Optimising oral cancer reconstruction: a retrospective cohort study on the modified radial forearm free flap technique to eliminate the need for a secondary donor site

The radial forearm free flap (RFFF) is commonly used in the reconstruction of oral cancer patients. Traditional RFFF (TRFFF) techniques, which often require a secondary donor site to repair the forearm defect, may result in a scar extending to the dorsal hand. This can lead to significant functional and aesthetic concerns in the forearm. We designed a modified RFFF (MRFFF) that incorporates a glasses-shaped flap and features deep venous drainage. To evaluate its effectiveness we conducted a retrospective chart review of 105 patients with oral squamous cell carcinoma who underwent reconstructive surgery between 2018 and 2022. These patients were treated either with a TRFFF (n = 60) or the newly developed MRFFF (n = 45). Our inclusion criteria, guided by preliminary surgical experience prior to initiating the study, stipulated that single oral defects should be no larger than 6 × 6 cm2, and adjacent double defects no larger than 3 × 6 cm2. Flap size, pedicle length, harvesting duration, and anastomosis during the surgical procedure were compared between the two techniques. Preoperative and postoperative oral function, recurrence, mortality, and dorsal scarring were recorded. One-week, one-month, and six-month postoperative subjective aesthetics assessments, and self-reported postoperative donor hand function, were measured using the Michigan hand questionnaire (MHQ). There were no significant differences between the groups in terms of flap size, pedicle length, harvesting time, anastomosis time, postoperative oral function, recurrence, and mortality. However, patients with a MRFFF did not require a second donor graft site and did not have scars extending to the dorsal forearm. They also had significantly improved postoperative aesthetic outcomes (1 week: 70.6%, 1 month: 62.2%) and donor hand function (1 week: 54.6%, 1 month: 40.4%) compared with the TRFFF group (p < 0.001). The MRFFF eliminates the need for secondary donor sites and improves primary donor site outcomes. It is versatile and can be employed for either single or composite oral defects. Through extensive case studies, we have defined its specific scope: it is suitable for single defects measuring no more than 6 × 6 cm2, or for composite defects no larger than 3 × 6 cm2. Furthermore, it does not compromise the functional recovery of the recipient site, and should be widely adopted for all qualifying patients.

Abdominal donor-site complications following autologous breast reconstruction: A multi-institutional multisurgeon study

BACKGROUND

The deep inferior epigastric perforator (DIEP) free flap is the gold standard procedure for autologous breast reconstruction. Although breast-related complications have been well described, donor-site complications and contributing patient risk factors are poorly understood.

METHODS

We examined a multi-institutional, prospectively maintained database of patients undergoing DIEP free flap breast reconstruction between 2015 and 2020. We evaluated patient demographics, operative details, and abdominal donor-site complications. Logistic regression modeling was used to predict donor-site outcomes based on patient characteristics.

RESULTS

A total of 661 patients were identified who underwent DIEP free flap breast reconstruction across multiple institutions. Using logistic regression modeling, we found that body mass index (BMI) was an independent risk factor for umbilical complications (odds ratio [OR] 1.11, confidence interval [CI] 1.04-1.18, p = 0.001), seroma (OR 1.07, CI 1.01-1.13, p = 0.003), wound dehiscence (OR 1.10, CI 1.06-1.15, p = 0.001), and surgical site infection (OR 1.10, CI 1.05-1.15, p = 0.001) following DIEP free flap breast reconstruction. Further, immediate reconstruction decreases the risk of abdominal bulge formation (OR 0.22, CI 0.108-0.429, p = 0.001). Perforator selection was not associated with abdominal morbidity in our study population.

CONCLUSIONS

Higher BMI is associated with increased abdominal donor-site complications following DIEP free flap breast reconstruction. Efforts to lower preoperative BMI may help decrease donor-site complications.

First do no harm: A patient-reported survey of split skin graft donor site morbidities following thin and super-thin graft harvest

The split-thickness skin graft (STSG) donor site is the commonest used during burn surgery which has its own complications and as such the focus should be on minimizing it. Modifications to practice in our unit which we believe aid this include limiting the amount of STSG taken and the harvest of super-thin STSGs, with 0.003-0.005 in. (0.08-0.13 mm) being the commonest dermatome settings used. A patient-reported survey via a mobile phone link to a questionnaire was sent to 250 patients who had a STSG for an acute burn between 1st August 2020 and 31st July 2021. Patient demographics were collected from electronic records including the thickness of the FTSG taken when recorded. Patient responses were statistically analyzed and logistic regression with backwards elimination was performed to explore which contributing factors led to an improved experience of the donor site. Questionnaire responses were obtained from 107 patients (43%). These were between one and two and a half years after the injury. Concerning early donor site issues, itch was a problem for 52% of patients, pain was a problem for 48% of patients. Less common problems (fewer than 25% of patients) were leaking donor sites, wound breakdown, and over-granulation. Regarding long-term outcomes, increased, decreased or mixed pigmentation at the donor site was reported by 32% patients at the time of the survey. Hyper-vascular donor sites were reported by 24% patients. Raised or uneven feeling donor sites were reported by 19% patients, firm or stiff donor sites by 13% patients, and altered sensation by 10% patients. At the time of the survey, 70% responders reported their donor site looked "the same or about the same as my normal skin". Of these, 62 reported how long it took for this to happen, and it equates to a third looking normal at 6 months and half looking normal at a year. For the 32 patients who reported their donor site looking abnormal, 72% were "not bothered" by it. Patients with super-thin grafts (0.003-0.005 in.) were significantly more likely to have normal sensation, normal stiffness, and be less raised at their donor sites than those who had thin grafts (0.006-0.008 in.). This survey gives important information on patients' experiences of donor site morbidity that may form part of an informed consent process and allow tailored advice. Furthermore, it suggests that super-thin grafts may provide a superior donor site experience for patients.

The use of artificial dermal substitutes for repair of the donor site following harvesting of a radial forearm free flap: A systematic review

BACKGROUND

Artificial dermal substitutes (ADMs) have been trialled to improve outcomes at the donor site following the harvesting of a radial forearm free flap (RFFF). This systematic review compares donor site aesthetic and functional outcomes, with the use of an ADM versus conventional practice.

METHODS

The databases Medline, Embase, Cochrane Library, Web of Science (Core Collection), and Scopus were searched for retrospective, prospective, and case-control studies and randomised control trials (RCTs) involving any ADM. Studies with adult patients having undergone RFFF harvesting and donor site repair with an ADM, commenting on appropriate clinical outcomes and without high risk of bias, were included. Direction-of-effect analysis was performed on relevant groupings of studies since heterogeneity in outcome measurement precluded meta-analyses.

RESULTS

Across eight non-comparative studies included, 132 patients had donor site coverage with AlloDerm™, Integra™, Matriderm™, or Rapiderm. Across 11 comparative studies included, 240 patients had donor site coverage with fish-skin matrix, AlloDerm™, amniotic membrane, MegaDerm™, Hyalomatrix, Integra™, or Matriderm™. Five out of 11 comparative studies demonstrated superior aesthetic outcomes with ADMs according to at least one aesthetic metric compared to controls, whilst 6/11 demonstrated superior functional outcomes with ADMs. No study demonstrated poorer aesthetic or functional outcomes with an ADM compared to conventional practice.

CONCLUSIONS

In summary, the lack of studies reporting poorer outcomes with them compared to conventional practices, and a cumulative effect direction in their favour, provide strong indications in support of the use of AlloDerm™, Integra™, or Matriderm™ grafts. Further comparative studies, including RCTs, are needed to reinforce these initial indications.

Planning of physiotherapeutic procedure in patients after mandible reconstruction taking into account donor site: a literature review

BACKGROUND

Mandible tumors are very rare. One of the main methods of the treatments is resection of the tumor and then reconstruction of the mandible. The donor site is often distant tissue-fibula or ilium. Following this, it is necessary to improve the patient in two ways, on one hand restoring the function of the mandible, and on the other hand, improving the donor site area. For that reason, physiotherapy after tumor resection and reconstruction of the mandible is very complicated. The aim of this bibliographic review was to find the methods of the reconstruction of the mandible in the context of patients' functional assessment after surgeries to create effective physiotherapeutic procedures in the feature.

METHODS

PEDro, Medline (PubMed), Cochrane Clinical Trials were searched.

RESULTS

767 articles were found. 40 articles were included to this literature review.

CONCLUSIONS

Authors showed different kinds of surgeries strategy for patients with tumors of the mandible. They also showed manners of patients' functional assessment in the localization of transplantation and donor site. It could be useful for physiotherapists during planning of comprehensive physiotherapy.

Is the retroauricular region a suitable donor site for full-thickness skin grafting in the era of mask wearing?

BACKGROUND

During the coronavirus disease 2019 (COVID-19) pandemic, the everyday use of face masks massively increased to prevent the spread of infection. Many people complain of ear pain and erosion when wearing a mask for extended periods of time. If prolonged mask usage is uncomfortable for ordinary people, a question arises-how much more inconvenient must mask wearing be for patients with a full-thickness skin graft (FTSG) donor site in the retroauricular region? Herein, we evaluated complications related to face mask use in 27 patients with a retroauricular FTSG donor site, with the goal of clarifying whether the retroauricular region is still an appropriate FTSG donor site in the context of the COVID-19 pandemic.

METHODS

Complications in 27 patients treated by FTSGs harvested from the retroauricular region from 2019 to 2021 were investigated. A questionnaire comparing the normal and the operated sides was administered. Pain, itching, soreness, deformity, and symmetry were further investigated.

RESULTS

Pain and itching were the only observed complications. The operated side was slightly more painful than the normal side in four patients (14.8%), and four patients (14.8%) reported itching on the operated side. However, all patients who experienced complications stated that the pain or itching did not interfere with mask wearing. Most symptomatic patients were older than 60 years of age (23.8%, p=0.185) and wore masks for longer periods of time (28.5%, p=0.326).

CONCLUSION

Few retroauricular donor site-related complications occurred, and none of these complications caused inconvenience in daily life. Therefore, in the COVID-19 pandemic, the use of the retroauricular region as an FTSG donor site remains appropriate.

Lower donor site morbidity with hamstring and quadriceps tendon autograft compared with bone-patellar tendon-bone autograft after anterior cruciate ligament reconstruction: a systematic review and network meta-analysis of randomized controlled trials

PURPOSE

To perform a meta-analysis of RCTs evaluating donor site morbidity after bone-patellar tendon-bone (BTB), hamstring tendon (HT) and quadriceps tendon (QT) autograft harvest for anterior cruciate ligament reconstruction (ACLR).

METHODS

PubMed, OVID/Medline and Cochrane databases were queried in July 2022. All level one articles reporting the frequency of specific donor-site morbidity were included. Frequentist model network meta-analyses with P-scores were conducted to compare the prevalence of donor-site morbidity, complications, all-cause reoperations and revision ACLR among the three treatment groups.

RESULTS

Twenty-one RCTs comprising the outcomes of 1726 patients were included. The overall pooled rate of donor-site morbidity (defined as anterior knee pain, difficulty/impossibility kneeling, or combination) was 47.3% (range, 3.8-86.7%). A 69% (95% confidence interval [95% CI]: 0.18-0.56) and 88% (95% CI: 0.04-0.33) lower odds of incurring donor-site morbidity was observed with HT and QT autografts, respectively (p < 0.0001, both), when compared to BTB autograft. QT autograft was associated with a non-statistically significant reduction in donor-site morbidity compared with HT autograft (OR: 0.37, 95% CI: 0.14-1.03, n.s.). Treatment rankings (ordered from best-to-worst autograft choice with respect to donor-site morbidity) were as follows: (1) QT (P-score = 0.99), (2) HT (P-score = 0.51) and (3) BTB (P-score = 0.00). No statistically significant associations were observed between autograft and complications (n.s.), reoperations (n.s.) or revision ACLR (n.s.).

CONCLUSION

ACLR using HT and QT autograft tissue was associated with a significant reduction in donor-site morbidity compared to BTB autograft. Autograft selection was not associated with complications, all-cause reoperations, or revision ACLR. Based on the current data, there is sufficient evidence to recommend that autograft selection should be personalized through considering differential rates of donor-site morbidity in the context of patient expectations and activity level without concern for a clinically important change in the rate of adverse events.

Comparison of the Effect of Using Collective Plus Ag Dressing and Vaseline Gauze Dressing in the Donor of Split-Thickness Burn Grafts

Background

Skin graft involves removing a part of the skin and using it in another part of the body. One of the most common reasons for using a graft is burns. We aimed to compare the effect of Colactive plus Ag dressing with Vaseline gauze dressing in donor sites of split-thickness skin grafts of burned patients.

Methods

The present study was conducted as a randomized clinical trial (RCT) in the Motahari burn Hospital, Tehran, Iran in 1401. The sampling method was done using Cochran's formula and available patients so 15 people were enrolled. The findings of the study were collected using a researcher-made form.

Results

The average duration of recovery, the amount and intensity of pain, and the amount of itching between the two types of Colative plus Ag plus Ag dressing with Vaseline gauze are statistically significant at the 95% confidence level. (P-value<0.05). In addition, the findings showed that the average amount of scar left by the wound in the two types of dressings examined is not statistically significant at the 95% confidence level (P-value > 0.05).

Conclusion

The use of Colactive silver dressing has less pain, less itching in the donor area, and a shorter average recovery time than Vaseline gauze. The use of the Colactive plus Ag will be more effective than Vaseline gauze.

Patient-reported outcomes and morbidity after head and neck reconstructions: An evaluation of fibular and scapular free flaps

BACKGROUND

Fibular (FFF) and scapular free flaps (SFF) are versatile tissue transfers for head and neck reconstruction. However, their relative morbidity has been sparsely studied. The primary goal of this study was to evaluate the morbidity and patient-reported outcome measures of these two reconstructive options.

MATERIALS AND METHODS

Case series of patients from 2017 to 2020 who underwent a FFF or SFF for head and neck ablation. Demographic and surgical outcome measures, such as Charlson Comorbidity Index (CCI), anesthetic time, donor site morbidity, and perioperative morbidity score (POMs) were extracted. Patients were contacted to complete the Decision Regret Scale (DRS), University of Washington Quality of Life (UW-QoL), Oral Health Impact-14, and limb specific functional outcome measures. Statistical analyses included a linear regression.

RESULTS

In total, 97 FFF (mean age 58.5, 62.9% male) and 55 SFF (mean age 64.8, 63.6% male) were included. Total surgical time was higher in the SFF group (p < 0.05) and they had more comorbidities (p < 0.01). SFF patients had lower POM scores on post-operative day three (p < 0.05) while FFF patients scored better on the UW-QoL Physical Domain (p < 0.01). The DRS for both groups (FFF mean DRS 22.7, SFF mean DRS 19.2) was similar. When adjusted for patient morbidity, however, the SFF group had less decisional regret (p < 0.05).

CONCLUSION

This is the largest comprehensive evaluation of patient-reported outcome measures for FFF and SFFs. SFFs required longer surgical times but had less early morbidity than FFFs. Patients who underwent either reconstructions reported mild decisional regret, proving these are generally well tolerated procedures.

Evaluation of liposomal bupivacaine infiltration at reconstructive skin graft donor sites in adolescent and young adult burn patients: A retrospective analysis

BACKGROUND

Postoperative pain at skin graft donor sites is frequently undertreated in burn patients, which can impair reconstructive outcomes and result in harmful psychological consequences. We find a critical need to explore and promote non-opioid, multimodal analgesics. Donor site infiltration of the local anesthetic liposomal bupivacaine in adolescent and young adult burn patients has not been previously investigated. Therefore, the goal of this study was to evaluate intraoperative liposomal bupivacaine infiltration for postoperative donor site pain control in adolescent and young adult burn patients undergoing reconstructive skin graft procedures.

METHODS

This retrospective analysis included patients aged 14-25 years, who underwent at least two reconstructive skin graft procedures, one that received donor site infiltration of the standard treatment (bupivacaine hydrochloride) and one that received donor site infiltration of liposomal bupivacaine. The final sample included 30 patients with a total of 44 liposomal bupivacaine cases and 53 standard treatment cases analyzed.

RESULTS

In the authors' five-year experience, the use of liposomal bupivacaine compared to standard treatment was associated with statistically significant decreases in 0-4 h postoperative pain scores (mean 1.4/10 versus 2.3/10, p = 0.04) and 0-24 h postoperative pain scores (mean 1.7/10 versus 2.4/10, p = 0.02). Neither analgesic was associated with adverse events. Differences in length of stay and inpatient postoperative opioid usage were not regarded as significant.

CONCLUSION

In this retrospective analysis, the authors report the first results that suggest intraoperative liposomal bupivacaine donor site infiltration may be associated with statistically improved patient outcomes in adolescent and young adult burn patients. However, the reported differences are most likely not clinically significant, establishing the necessity for further evaluation of using liposomal bupivacaine in this unique patient population.

Dimensional changes of keratinized mucosa after accordion versus conventional free gingival graft around dental implants: A randomized two-arm parallel clinical trial

OBJECTIVES

Free gingival graft (FGG) is the most effective way to increase the apico-coronal width of the keratinized mucosa. In case of limited donor tissue, the accordion technique can be used. This study compared FGG for dimensional and clinical changes using accordion and conventional methods.

MATERIALS AND METHODS

Ninety-four implants with keratinized tissue deficiency (< 2mm) were randomly assigned to treatment with accordion (49 implants) and conventional (45 implants) FGG. Endpoints including apico-coronal keratinized tissue width, vertical shrinkage, vestibular depth, probing depth, bleeding on probing, and plaque index were measured. The graft harvesting and recipient bed preparation method were similar in the two groups, and the only difference was the graft length. FGG was harvested with a length 40% shorter than the mesiodistal length of the recipient area in the accordion method and as much as the recipient area in the conventional method.

RESULTS

vertical graft shrinkage 1, 3 and 6 months following conventional graft placement was 12.04±14.99, 17.12±20.40, 23.29±24.63 percent, respectively. In the accordion graft group, the shrinkage was significantly greater with 30.10±16.12, 36.99±15.51, 43.75±18.78 percent at 1, 3 and 6 months, respectively (p-Value<0.001). Other factors did not show a clinically significant difference between the two groups.

CONCLUSIONS

Comparison of vertical shrinkage changes shows that the shrinkage rate in the accordion group is significantly higher than the conventional group.

Breast-related and body-related quality of life following autologous breast reconstruction is superior to implant-based breast reconstruction - A long-term follow-up study

INTRODUCTION

The better survival rates after breast cancer allow for setting of long-term goals, such as Quality of Life (QoL) and aesthetic outcomes following breast reconstruction. Studies find a higher breast-related QoL and greater satisfaction with breasts following autologous breast reconstruction (ABR) compared to implant-based breast reconstruction (IBR). However, aesthetic results from donor sites can influence body image. This concern is little addressed in the literature. Therefore, the aim of this study was to compare the long-term breast-related and body-related QoL of women who underwent ABR to women who underwent IBR.

MATERIAL AND METHODS

A multicenter, cross-sectional survey was conducted between November and December 2020 among women who underwent postmastectomy breast reconstruction between January 2015 and December 2018. A general questionnaire, the BREAST-Q, and the BODY-Q were used to collect data. Multivariable linear regression was performed to adjust differences in Q-scores for potential confounders.

RESULTS

In total, 336 patients were included (112 IBR, 224 ABR). Autologous reconstruction resulted in significantly higher mean scores in all subdomains of the BREAST-Q. On the BODY-Q, IBR scored significantly higher on scars, while ABR scored moderately to significantly higher on all other scales. Despite a lower mean score on Hips & outer thighs in women with Lateral Thigh Perforator (LTP) flap reconstruction, no negative influence on body image was found in these women.

CONCLUSIONS

Long-term breast-related and body-related outcomes of ABR are superior to IBR. Donor site aesthetic does not adversely affect body image in women who underwent free flap breast reconstruction.

Aesthetic reconstruction for syndactyly using the "gradation skin graft" from the plantar instep area

In syndactyly, the donor site of the skin graft should have the characteristics of both the dorsal and the plantar or palmar skin because the skin defects after the dividing procedure are at the lateral sides of the digits. The plantar instep region has a color and texture border between the dorsal and plantar skin as a gradational boundary belt. We performed "gradation skin grafting" including the belt for syndactyly. We retrospectively analyzed 110 skin graft sites in 56 patients, aged ≤ 2 years, with syndactyly of the hand or foot. The follow-up durations were ≥ 6 months. The skin graft sites were divided into the gradation skin graft (G[+]) and the traditional skin graft (G[-]) groups. They were examined for matching of the skin graft with the circumferential skin, the causes of mismatching, the closing method of the donor site, and the complications. Regarding skin graft matching, the excellent rate of achievement was greater in the G(+) than in the G(-) group (P < 0.01). The causes of mismatching were misalignment of the gradational boundary belt in the G(+) group and postoperative pigmentation in the G(-) group. All the donor sites were closed directly without complications. The gradation skin graft for syndactyly was cosmetically superior to the traditional one from the submalleolar area. The design's hazard is that the gradational boundary belt of the skin graft should match the alignment with the gradational boundary belt around the skin defect of the digits.

The ban of the ipsilateral limb as a skin graft donor site after melanoma excision: A critical review

Split-thickness skin grafts are often applied in the management of primary cutaneous melanoma. It is routine surgical practice to use the contralateral limb because of the alleged risk of donor site metastases that may occur when the ipsilateral limb is used. The rationale and clinical evidence for this routine were assessed in light of current understanding of pathways of metastasis of melanoma. We found the preference for the contralateral limb to go back to Paget's ideas on melanoma spread from 1889, and the clinical observation of five cases of split-thickness skin graft donor site metastases in a series of 226 tumours, published in 1962. We traced ten additional reported cases of melanoma metastases occurring in the skin graft donor site. Contralateral donor sites were involved in seven of these cases. In light of current knowledge, the occurrence and the location of any split skin donor site metastasis are to be considered as mere indicators of an aggressive course of systemic disease. Any location of a split skin donor site, whether ipsilateral or contralateral in relation to the primary tumour, may become the location of metastases but chances that such metastases occur are extremely rare. Because of the lack of evidence in favour of the use of the contralateral limb and because of sound considerations in favour of using the ipsilateral limb, we conclude that there is no objective argument to sustain the dogmatic ban of the ipsilateral limb as a donor site for a split-thickness skin graft in melanoma surgery.

Novel skin graft donor site for the scalp transposition flap

Transposition scalp flaps are a versatile solution for soft-tissue cover in a multitude of scalp defects. They are frequently used to reconstruct larger skin cancers that involve the outer table of the cranium in addition to covering neurosurgical bony defects and hardware. The transposition flap requires the donor site to be grafted using a split-thickness graft, which results in a secondary wound elsewhere on the body, commonly the lateral thigh. Although quite routine in such surgery, this procedure does require another body area to be prepared and draped. We sought to streamline this procedure with an adjustment to the location of the donor site. In harvesting the graft from the skin of the flap itself, we localised all surgery to one area, which has a number of logistical and patient-care advantages. Our experience has shown significant benefits from this technique and this is now our chosen and recommended donor site for these reconstructions.

Observational study of the long-term impact of donor-site sequelae after head and neck reconstruction by free anterolateral thigh flap

OBJECTIVE

Free anterolateral thigh flap has many applications in head and neck reconstruction surgery. The aims of the present study were: (1) to assess functional and esthetic sequelae of harvesting for oncologic purposes; and (2) to assess long-term impact of harvesting on quality of life according to patient and to physician.

MATERIALS AND METHODS

Forty-one patients undergoing reconstruction by free anterolateral thigh flap following oncologic head and neck surgery were assessed by questionnaire at>6 months postoperatively. Donor site sequelae were assessed in consultation. Harvesting impact was assessed on 5-point Likert scales by patient and by surgeon.

RESULTS

Thirty nine percent of patients showed≥1 sequelae. Donor site sequela impact on sport, daily living and work was assessed by patients as none or mild in 94%, 98% and 100% of cases, respectively. Sixty-one percent of patients and 58.5% of surgeons considered scar esthetics to be discreet or very discreet.

CONCLUSION

Morbidity related to anterolateral thigh flap harvesting was low, and functional sequelae at the donor site were well tolerated. The scar was only moderately satisfactory, but could easily be hidden.

Split-thickness skin graft donor-site morbidity: A systematic literature review

The purpose of this systematic literature review is to critically evaluate split-thickness skin graft (STSG) donor-site morbidities. The search of peer-reviewed articles in three databases from January 2009 to July 2019 identified 4271 English-language publications reporting STSG donor-site clinical outcomes, complications, or quality of life. Of these studies, 77 met inclusion criteria for analysis. Mean time to donor-site epithelialization ranged from 4.7 to 35.0 days. Mean pain scores (0-10 scale) ranged from 1.24 to 6.38 on postoperative Day 3. Mean scar scores (0-13 scale) ranged from 0 to 10.9 at Year 1. One study reported 28% of patients had donor-site scar hypertrophy at 8 years. Infection rates were generally low but ranged from 0 to 56%. Less frequently reported outcomes included pruritus, wound exudation, and esthetic dissatisfaction. Donor-site wounds underwent days of wound care and were frequently associated with pain and scarring. Widespread variations were noted in STSG donor-site outcomes likely due to inconsistencies in the definition of outcomes and utilization of various assessment tools. Understanding the true burden of donor sites may drive innovative treatments that would reduce the use of STSGs and address the associated morbidities.

Aesthetic Comparison of Abdominal Donor Site Scar Between Absorbable Dermal Staple and Subcutaneous Suture after Autologous Breast Reconstruction: A Prospective Randomized Controlled, Double-Blinded Study

BACKGROUND

Abdominal tissue transfer has become the most commonly used tool for breast reconstruction. However, a secondary operator is often responsible for donor closure, which leaves dissatisfaction to patients due to inconsistent donor scars. Now, an absorbable dermal stapler is popularized worldwide and currently used for wound closure in many surgical fields. In this study, we aim to evaluate the abdominal donor site scar in using an absorbable dermal staple compared to a conventional suture.

METHODS

This is a prospective, randomized controlled and double-blinded study. Between January 2018 and April 2019, a total of 30 patients who underwent breast reconstruction using abdominal flap were included. Donor sites were divided into equal halves, and the each dermal layer was sutured with either dermal staples or traditional suturing, respectively. At 1, 3 and 6 months after operation, the scar was evaluated by two blinded plastic surgeons by using the modified Manchester scar scale (MSS).

RESULTS

An averaged sum of modified MSS was lower for the side sutured with a dermal stapler at the first month (11.76 ± 2.12 vs. 12.28 ± 2.03, p = 0.097), third month (12.17 ± 1.86 vs. 12.62 ± 2.31, p = 0.301) and sixth month (11.28 ± 2.63 vs. 12.14 ± 2.76, p = 0.051). Also, the dermal stapler side scored significantly higher for patient satisfaction than did the suture side (4.03 ± 0.98 vs 3.66 ± 0.97, p < 0.05).

CONCLUSION

The objective outcome of the scar closed by an absorbable dermal stapler was not statistically superior to conventional suturing. (p > 0.05) In the subjective outcome, however, it showed a significantly higher patients' satisfaction (p < 0.05).

The influence of harvesting free gingival graft on self-reported pain perception: A randomized two-arm parallel clinical trial

Background/purpose

Free gingival graft (FGG) is used as an effective method to increase the width of keratinized tissue. However, it can cause pain at the donor site. Techniques accompanied by lesser tissue harvesting can reduce pain after surgery. The purpose of this study was to evaluate the self-reported pain perception following harvesting FGG using conventional and accordion methods.

Materials and methods

In this randomized clinical trial study, 31 patients with a deficiency of keratinized tissue around implant were investigated. Sixteen subjects in the accordion group and 15 subjects in the control group received conventional FGG. In the accordion group, FGG was harvested with a length of 60% of the mesiodistal length of the recipient area and with the same length as the mesiodistal length of the recipient area in the conventional group. The patients were asked to record their daily pain using a numerical rating scale.

Results

The severity of the pain after reaching to the peak on the second day was reduced and reached zero at day 14 in both groups. Pain severity showed no significant difference between the treatment groups. The highest level of pain was reported in the conventional group in those subjects under 50 years old, and the lowest one was in the conventional group's subjects above 50 years old. There was no difference between men and women in the reported pain between the treatment groups.

Conclusion

Harvesting graft with a smaller size in the accordion group has no effect on reducing pain.

Aesthetic Reconstruction of Fingers and Thumbs With the Vascularized Half-Big Toenail Flap With Minimum Donor Site Morbidity

Purpose

The vascularized half–big toenail flap is a short-pedicle free vascularized flap approximately 30 mm in size that contains a fibular half-nail with a 5-mm skin edge and the partial distal phalanx bone. The fingertip skin of the amputated finger is reflected to cover the skin deficiency. The sensation and function are maintained at the donor site, and primary wound closure of the donor site is possible. This study aimed to evaluate the clinical outcomes of thumb and finger reconstruction operations performed using this flap.

Methods

We assessed 16 patients (19 digits) with digit amputation who underwent this procedure. We evaluated the following parameters: reconstructed digits, amputation level, survival rate, period until bone union, elongated length, morphologic indices, feeding artery, vein distribution, static 2-point discrimination, and patient occupation. We used the Michigan Hand Outcomes Questionnaire for the evaluation of the function and appearance of the arm.

Results

We reconstructed 3 thumbs and 16 fingers. No patients with zone I or V or palm amputation underwent surgery. Flap survival was obtained in all cases, including one atrophic case. Elongated length was 14.1 mm (range, 0–30 mm). The width and longitudinal/axial convexity of the transferred nail increased and the length decreased, whereas the width of the donor site nail increased at final follow-up. Reasonable sensation of the flap was obtained. The feeding artery was the plantar digital artery in 15 toes, the branch in 1, and the arterial anonymous vessel in 3. We could harvest the vein in the first web in 16 toes. All patients went back to their former jobs.

Conclusions

The aesthetic and functional outcomes of the reconstructed thumbs and fingers significantly improved. Donor site functional morbidity was minimum. Nevertheless, patients’ expectations regarding the reconstructed digit seemed to be that of an intact digit.

A novel design of palatal stent to reduce donor site morbidity in periodontal plastic surgery

Background/ purpose

The connective tissue graft from hard palate is a reliable graft technique that has been used for achieving root coverage, increasing keratinized tissue width and thickness in periodontal plastic surgeries. Donor site morbidities, including complications from postoperative bleeding, pain during healing phase, difficulties in eating and speaking and unexpecting healing patterns, are always a concern for both doctors and patients. The aim of this study was to investigate a novel design of palatal stent to reduce these complications and provide patient with a smooth healing experience after soft tissue harvesting from hard palate.

Materials and methods

Eight patients requiring connective tissue graft from palatal site were included in the study. The palatal stents made with light-curing hybrid composite resin were fabricated and tried in for patients prior to the periodontal plastic surgeries. Stent was delivered immediately without other dressing material or suture after the graft harvesting procedure for blood clot stabilization. Bleeding tendency was evaluated at the completion of the procedure. Patients came back for follow up in 1 week, 2 weeks and 1 month after the surgery. In the consecutive clinical cases, all patients reported minimal postoperative pain and discomfort (score ranged between 0 and 2). Both chewing and swallowing were not affected when wearing the stent, while four patients reported speaking inconvenience influenced by the stent.

Results

In the consecutive clinical cases, all patient reported minimal postoperative pain and discomfort (Score ranged between 0 and 2). Both chewing and swallowing were not affected when wearing the stent while four patients reported speaking influenced by the stent.

Conclusion

The novel design of palatal stent reduces donor site morbidity and provides patient with a good healing experience after soft tissue harvesting from hard palate.

[Effects of free perforator propeller flap from buttock in repairing deep wound of buttock]

Objective: To explore the effects of free perforator propeller flap from buttock in repairing deep wound of buttock. Methods: From February 2016 to May 2018, 27 patients with buttock skin and soft tissue defects caused by various reasons were admitted to the Burn and Plastic Surgery Center of the 940th Hospital of the Joint Logistic Support Force of People's Liberation Army, including 19 males and 8 females, aged from 28 to 70 years. Among the protopathy, there were 14 cases of pressure sores, 7 cases of scar carcinoma, 2 cases of low-temperature scald, 2 cases of abscess, and 2 cases of pilonidal sinus. The wounds were located in the sacrococcygeal region in 15 cases, the ischial tuberosity in 8 cases, and the rest area of buttock in 4 cases after injury or lesion resection. The size of wounds ranged from 4.0 cm×4.0 cm to 12.0 cm×6.0 cm after debridement or extended resection. The free perforator propeller flaps from buttock with areas of 8.0 cm×4.0 cm-16.0 cm×6.0 cm were used to repair the wounds, and the donor sites were selected adjacent to the wounds where the skins were relatively loose. All flaps took buttock free perforator vessels as the axis and were transferred in propeller-type to repair the wounds. The donor sites were directly closed and sutured. The survival, complications, and follow-up of flaps were recorded. Results: All the flaps survived 100% in 27 patients. Congestion formed under flaps 2-6 days post operation in 2 patients due to inadequate drainage, which were healed after dressing change and drainage for 14-18 days. The sutures of flaps in the other cases were removed in 10-14 days post operation, and the wounds were healed. Follow-up for 2-12 months showed that the shapes of flaps and the donor sites were plump, which were not much different from the healthy sides, and the flaps could bear weight. Conclusions: Repairing buttock deep wound with buttock free perforator propeller flap has good effects. The donor site can be designed in the area adjacent to the wound where the skin is relatively loose and can be directly closed and sutured while repairing the wound, which can ensure plump buttock appearance.

[Clinical effects of perforating branch flaps of medial vastus muscle in repairing secondary wounds in donor sites of free anterolateral femoral perforator flaps]

Objective: To investigate the clinical effects of perforating branch flaps of medial vastus muscle in repairing secondary wounds in donor sites of free anterolateral femoral perforator flaps. Methods: From August 2014 to December 2016, 12 patients (8 males and 4 females, aged 35-72 years) with skin and soft tissue defects of extremities associated with tendon and bone exposure were treated in Hanzhong Central Hospital. The sizes of the primary wounds after debridement were 10 cm×8 cm-22 cm×14 cm, and the wounds were repaired with 12 cm×10 cm-24 cm×16 cm free anterolateral femoral perforator flaps. The anterolateral femoral donor sites, which were 8.0 cm×4.0 cm-14.0 cm×7.5 cm in the secondary wounds after skin extensional suture, were repaired with perforating branch flaps of medial vastus muscle in the size of 9.0 cm×5.0 cm-15.0 cm×8.5 cm. The medial femoral donor sites were sutured directly. Results: All the perforating branch flaps of medial vastus muscle and free anterolateral femoral perforator flaps survived in 12 patients. Following up for 6 to 12 months, the medial femoral perforator flaps had good local shape and texture. The flaps of 8 patients without cutaneous nerve transection were sensitive. The sensation of the flaps of the other 4 patients gradually recovered, and the functions of the ipsilateral knee joints were normal. Conclusions: The medial femoral perforator flap has a stable anatomy and abundant blood supply, which can be used to repair the secondary wound in the donor site of the free anterolateral femoral perforator flap conveniently. It is safe and easy to be popularized. Moreover, it has a good shape and function after operation.

The regeneration at non vascularized fibular harvest site and development of ankle valgus in donor leg-investigations done over two time points

INTRODUCTION

We retrospectively observed the fibular regeneration in non vascularized harvest in children and development of ankle valgus at 2 time points to find any possible relationship between them.

MATERIAL AND METHODS

A 6 month period was chosen as the first time frame to assess regeneration and ankle valgus. Radiographs at this time and a subsequent follow up were studied for regeneration, lateral distal tibial ankle (LDTA) and fibular station. The donor sites were divided into complete and incomplete regeneration groups and compared statistically.

RESULTS

There were 12 patients with 18 harvested fibulae. Ten out of 18 fibulae (56%) had complete longitudinal regenerate at 6 months. Two fibulae underwent delayed union. Of 8 incomplete regenerates at 6 months, 6 (75%) were also incomplete beyond a follow up of 2.75 years. Incomplete group had radiological ankle valgus in 6 legs (75%) at 6 months increased to 7 at follow up. Further, LDTA for incomplete group was significantly lower than complete group (p = 0.025) at 6 months.

CONCLUSIONS

More than half of harvested legs (56%) had complete longitudinal fibular regeneration at 6 months. Of incomplete regenerates at 6 months, three fourth remained so beyond 2.5 years. Ankle valgus was found strongly related to long standing fibular non regeneration. Radiological ankle valgus developed early in the incomplete regenerate group.

Proliferative and osteogenic differentiation capacity of mesenchymal stromal cells: Influence of harvesting site and donor age

Human mesenchymal stromal cells (hMSCs) are the cellular source of new bone formation and an essential component of autologous bone grafts. Autologous bone graft harvesting is routinely conducted at the iliac crest, although alternative donor sites with lower complication rates are available. Thus, the aim of this study was to compare hMSCs harvested from the iliac crest and the proximal tibia regarding their proliferative and osteogenic differentiation capacity. Furthermore, we investigated the influence of donor age on these biological properties. HMSCs were isolated from iliac crest or proximal tibia bone grafts of 46 patients. Proliferative capacity was assessed by cumulative population doublings, population doubling time, colony forming units and cell proliferation assays. Osteogenic capacity was assessed by quantification of extracellular calcium deposition and marker gene expression levels. The number of hMSCs per gram harvested tissue was determined. Furthermore, the adipogenic and chondrogenic differentiation capacity were quantified using BODIPY and Safranin Orange staining, respectively. Additional analyses were carried out after grouping young (18-49 years) and aged (≥50 years) donors. HMSCs derived from the proximal tibia featured a comparable proliferative and osteogenic differentiation capacity. No significant differences were found for any analysis conducted, when compared to hMSCs obtained from the iliac crest. Furthermore, no significant differences could be revealed when comparing young and aged donors. This was equally true for hMSCs from both donor sites after comparison within the same age group. Our study demonstrates comparable biological properties of hMSCs derived from both donor sites, the iliac crest and the proximal tibia. Furthermore, aging does not alter proliferative and osteogenic differentiation capacity. Consequently, the proximal tibia should be considered more closely as an alternative donor site in patients of all age groups.

Oral quality of life after buccal mucosal graft harvest for substitution urethroplasty. More than a bite?

INTRODUCTION

The aim of our study was to analyze the oral quality of life (QoL) in patients with urethral stricture treated with BMG by using a validated questionnaire (OIDP).

MATERIALS AND METHODS

A prospective, single-arm, observational single-centre study of a cohort of patients scheduled for BMG Urethroplasty was conducted. OIDP assesses the impact of oral conditions on daily activities including an oral QoL question (0-10). The questionnaire was self-administered before, 3 months postoperatively and at the end of the study. Means, pre- and postoperatively, were compared. Multivariate analysis was performed to analyze the risk factors for a low quality of life (<8) after surgery.

RESULTS

We included 41 patients (2013-2017). The mean preoperative oral QoL was 9.33 points (SD1.16). Preoperative mean OIDP dimensional score and global score were 0,5 (SD:0.02) and 0,8%. The most frequently preoperative altered aspect was hygiene. Mean oral QoL, 3 months after surgery, was 8,56 (SD1.89) and OIDP dimensional score and global score were 0,67 (SD0.21) and 1,1%. Mean oral QoL at the end of the study (mean 3,12 years) was 8,50 (SD1.13). OIDP dimensional score and global score were 0,7 (SD 0.16) and 1,1%.The most frequently altered aspect at the end of the study was eating. No statistical (p = 0.07) decrease in oral QoL was found. The increase in OIDP dimensional and global score was also not statistically significant. Neither age nor smoking, diabetes mellitus, cardiovascular morbidity, previous OIDP score, width, length of the graft, or surgery success could explain a low oral QoL alter graft harvesting.

CONCLUSIONS

BMG harvesting is not free of problems at the donor site. Eating seems to be the most affected aspect after surgery. Nevertheless, those sequelae do not induce a reduction in oral QoL.

Somatosensory changes at forearm donor sites following three different surgical flap techniques

BACKGROUND

The aim of this study was to investigate the somatosensory changes at the forearm donor region after using different types of modified flap surgical techniques.

METHODS

Thirty-one patients, who underwent oral and maxillofacial reconstructive surgery involving the use of a traditional radial forearm flap (TRFF) or two modified radial forearm flap techniques (MRFF-I; MRFF-II), participated in the study. Cold detection threshold (CDT), warm detection threshold (WDT), cold pain threshold (CPT), heat pain threshold (HPT), pressure pain threshold (PPT), mechanical detection threshold (MDT), and mechanical pain threshold (MPT) were assessed at four sites of the forearms corresponding to the middle of the vascular pedicle (VP) area, the middle of the forearm flap area, and the corresponding contralateral sites (cVP and cFF) at about 5.0 ± 1.9 months after the surgery. Data were analysed with one-way ANOVA, and post-hoc tests were performed using Tukey's Honest Significant Difference test.

RESULTS

Significant differences between the VP and cVP sites were detected for WDT (P < 0.001) in TRFF and for WDT (P < 0.001) and MDT (P = 0.006) in MRFF-I. Significant differences among TRFF, MRFF-I, and MRFF-II at the VP site were detected for CDT (P = 0.022), WDT (P < 0.001), and MDT (P = 0.015). MRFF-II was associated with significantly higher sensitivity compared to that of TRFF for WDT (P = 0.017) and higher sensitivity compared to that of MRFF-I for CDT (P = 0.017), WDT (P < 0.001), and MDT (P = 0.013).

CONCLUSIONS

Significant sensory loss was detected for all types of surgical procedures with free forearm flaps. However, the MRFF-II was associated with a better sensory recovery at short follow-up after surgery. These results suggest that a longer follow-up period and larger sample size should be included in future studies.

[Clinical application of the bilateral radial forearm flap for tongue cancer reconstruction]

The forearm radial flap is a reliable flap for the repair of the defect caused by tongue cancer resection. The clinical data of 11 tongue cancer patients that received this surgery were retrospectively analyzed. The clinical application of this technique is preliminarily discussed.

The antimicrobial spectrum of Xeroform®

INTRODUCTION/BACKGROUND

Xeroform^® is a petrolatum-based fine mesh gauze containing 3% bismuth tribromophenate. Bismuth, similar to other metals, has antimicrobial properties. Xeroform^® has been used for decades in burn and plastic surgery as a donor site dressing and as a covering for wounds or partial thickness burns. Despite this, the antimicrobial spectrum of Xeroform^® remains largely unknown. We examined the in-vitro efficacy of Xeroform^® against common burn pathogens using zone-of-inhibition methodology in a commercial research facility.

METHODS/DESIGN

Pure strains of 15 common burn pathogens including Methicillin-resistant Staphylococcus aureus (MRSA), Methicillin-sensitive Staphylococcus aureus (MSSA), Staphylococcus epidermidis, Pseudomonas aeruginosa, Enterobacter cloacae, Escherichia coli, Candida albicans, Vancomycin resistant Enterococcus, Acinetobacter baumennii, Klebsiella pneumonia, Extended spectrum beta-lactamase producing Klebsiella, Beta hemolytic Streptococcus pyogenes, Proteus mirabilis, Serratia marcescens, and Salmonella enterica ssp. Enterica were inoculated at a strength of 10⁶-10¹⁰ CFU/ml onto appropriate agar plates. A sterile 1 in² Xeroform^® square was placed in the center of each plate, and the Zone of Inhibition (ZOI) was measured following 18-24h of incubation at 37°C. A second bismuth pharmaceutical (bismuth subsalicylate, Pepto-Bismol^®) was then tested using the same methodology against the same strains of MRSA, MSSA, E. coli, K. pneumonia and S. marcescens. Finally, 3% w/v bismuth tribromophenate in glycerol suspension was tested against 13 burn pathogens for antimicrobial activity independent of the Xeroform^® dressing by measure of Zone of Inhibition.

RESULTS/FINDINGS

For Xeroform^®, none of the fifteen pathogens had a measurable zone of inhibition on any plate. Bismuth subsalicylate showed a zone of inhibition for MSSA in 3 plates (mean of 47.2mm), in one of three plates for MRSA (13.8mm), and in one of three plates for S. marcesens (89.6mm). There was no zone of inhibition seen for K. pneumonia or E. coli. Bismuth tribromophenate, when not bound to Xeroform^® showed activity against 12 of 13 pathogens.

CONCLUSIONS/IMPLICATIONS

While bismuth subsalicylate, and bismuth tribromophenate unbound to Xeroform^® demonstrate antimicrobial activity, it appears that Xeroform^® dressings do not. The utility of Xeroform^® in burn medicine may relate more to use as an impervious dressing than to antimicrobial effect. Donor sites are clean surgical wounds and clean partial thickness burns may have minimal colonization present. In such circumstances, an inactive and impervious dressing may be all that is necessary to promote wound healing.

Autogenous bone grafts in oral implantology-is it still a "gold standard"? A consecutive review of 279 patients with 456 clinical procedures

Background

This study assessed the clinical outcomes of graft success rate and early implant survival rate after preprosthetic alveolar ridge reconstruction with autologous bone grafts.

Methods

A consecutive retrospective study was conducted on all patients who were treated at the military outpatient clinic of the Department of Oral and Plastic Maxillofacial Surgery at the military hospital in Ulm (Germany) in the years of 2009 until 2011 with autologous bone transplantation prior to secondary implant insertion. Intraoral donor sites (crista zygomatico-alveolaris, ramus mandible, symphysis mandible, and anterior sinus wall) and extraoral donor site (iliac crest) were used. A total of 279 patients underwent after a healing period of 3–5 months routinely computer tomography scans followed by virtual implant planning. The implants were inserted using guided oral implantation as described by Naziri et al. All records of all the consecutive patients were reviewed according to patient age, history of periodontitis, smoking status, jaw area and dental situation, augmentation method, intra- and postoperative surgical complications, and surgeon’s qualifications. Evaluated was the augmentation surgical outcome regarding bone graft loss and early implant loss postoperatively at the time of prosthodontic restauration as well a follow-up period of 2 years after loading.

Results

A total of 279 patients underwent 456 autologous augmentation procedures in 546 edentulous areas. One hundred thirteen crista zygomatico-alveolaris grafts, 104 ramus mandible grafts, 11 symphysis grafts, 116 grafts from the anterior superior iliac crest, and 112 sinus lift augmentations with bone scrapes from the anterior facial wall had been performed. There was no drop out or loss of follow-up of any case that had been treated in our clinical center in this 3-year period. Four hundred thirty-six (95.6%) of the bone grafts healed successfully, and 20 grafts (4.4%) in 20 patients had been lost. Fourteen out of 20 patients with total graft failure were secondarily re-augmented, and six patients wished no further harvesting procedure. In the six patients, a partial graft resorption was detected at the time of implantation and additional simultaneous augmentation during implant insertion was necessary. No long-term nerve injury occurred. Five hundred twenty-five out of 546 initially planned implants in 259 patients could be inserted into successfully augmented areas, whereas 21 implants in 20 patients due to graft loss could not be inserted. A final rehabilitation as preplanned with dental implants was possible in 273 of the 279 patients. The early implant failure rate was 0.38% concerning two out of the 525 inserted implants which had to be removed before the prosthodontic restoration. Two implants after iliac crest augmentation were lost within a period of 2 years after loading, concerning a total implant survival rate after 2 years of occlusal loading rate of 99.6% after autologous bone augmentation prior to implant insertion.

Conclusions

This review demonstrates the predictability of autologous bone material in alveolar ridge reconstructions prior to implant insertion, independent from donor and recipient site including even autologous bone chips for sinus elevation. Due to the low harvesting morbidity of autologous bone grafts, the clinical results of our study indicate that autologous bone grafts still remain the “gold standard” in alveolar ridge augmentation prior to oral implantation.

Extensive Donor Site Keloids in Follicular Unit Extraction Hair Transplantation

Hair transplantation, a generally regarded as a safe surgical modality for the treatment of androgenetic alopecia, is not without its potential risks and complications. A case of an extensive keloid formation at donor site following follicular unit extraction is discussed. Hair transplant surgeons should be aware of this significant potential complication, especially in patients having previous keloidal tendencies to avoid such disastrous outcomes.

[Morbidity of autologous bone harvesting in implantology: Literature review from 1990 to 2015]

INTRODUCTION

Autogenous bone is commonly used in pre-implant bone reconstructions. Five harvesting sites are frequently used: mandibular symphysis and ramus, iliac crest, calvaria and tibia. One of the deciding criterions among these sites is the donor site morbidity. The purpose of our work was to analyze the intra- and postoperative complications that may occur on the different donor sites.

MATERIAL AND METHODS

An automatic and manual search on Medline covering the period 1990-2015 was made. Human studies, in English or French language, detailing the complications linked to bone harvest done for pre-implant surgery were included.

RESULTS

Eighty-three clinical trials or case reports were analyzed. Iliac crest, mandibular symphysis and ramus donor sites were afflicted with the highest pain scores and sensory disturbances. Iliac and tibial bone harvests were complicated by walk disturbances in the first weeks. Some rare neurological complications have been reported after calvarial bone harvest.

DISCUSSION

Although commonly used, iliac crest bone harvest is responsible for significant morbidity. Calvarial harvest is related to the lowest morbidity. It has to be performed by an experienced team in order to reduce the risk of neurologic injury. Regarding intraoral donor sites, mandibular symphysis becomes less popular. Mandibular ramus harvest has the lowest complication rate and is well accepted by patients.

The scalp as a donor site for skin grafting in burns: retrospective study on complications

Background

Split skin grafting (SSG) is the cornerstone in the treatment of deep burns and large skin defects. Frequently used donor sites are the thigh, abdomen and buttocks. The scalp is less common while considered as a reliable donor site. Advantages are a large surface area, rapid wound healing, cosmetically favourable results and multiple harvests from the same donor site. Complications include scab formation, chronic folliculitis and alopecia but have been recorded sporadically in previous studies. This article evaluates the complication rate of the scalp donor site in the treatment of deep burns in the Beverwijk Burn Centre.

Methods

A retrospective study was performed of all patients who received a skin graft from the scalp at the Beverwijk Burn Centre between January 2004 and December 2012. Data were collected from medical files of included patients, including gender, age, type of burn (scald, flame, other) and total body surface area (TBSA) burned at the time of first surgery. Postoperative variables were healing time of the donor site and incidence of complications. During follow-up, the incidence of late complications was reviewed.

Results

A total number of 105 grafts were analysed in 93 patients: 58 males (62 %) and 35 females (38 %), with a median age of 2 years and 3 months old. Of the patients, 30 (32 %) had flame burns and 57 (61 %) had scald burns. Eighty-seven percent of patients had a TBSA burned of 5 % or less. All donor sites healed within 14 days. No alopecia or scar hypertrophy developed at the donor sites. Two patients (2.2 %) developed folliculitis; one patient (1.1 %) showed scab formation.

Conclusions

The scalp as a donor site in our Burn Centre shows a comparable short-term complication rate to the previous literature, with quick healing and no long-term complications. Therefore, we propose the consideration of the scalp as a primary donor site, especially in young children, where the scalp offers a larger donor site area than the buttocks or thighs.

Interim pressure garment therapy (4-6 mmHg) and its effect on donor site healing in burn patients: study protocol for a randomised controlled trial

Background

Pressure garment therapy (PGT) is well accepted and commonly used by clinicians in the treatment of burns scars and grafts. The medium to high pressures (24–40 mmHg) in these garments can support scar minimisation, and evidence is well documented for this particular application. However, PGT specifically for burn donor sites, of which a sequela is also scarring, is not well documented. This study protocol investigates the impact of a low pressure (4–6 mmHg) interim garment on donor site healing and scarring. With a primary purpose of holding donor dressings in place, the application of the interim pressure garment (IPG) appears to have been twofold. IPGs for donor sites have involved inconsistent application with a focus on securing wound dressing rather than scar management. However, anecdotal and observational evidence suggests that IPGs also make a difference to some patient’s scar outcomes for donor sites. This study protocol outlines a randomised controlled trial designed to test the effectiveness of this treatment on reducing scarring to burn donor sites.

Methods/design

This study is a single-centre, single (assessor)-blinded, randomised control trial in patients with burns donor sites to their thighs. Patients will be randomly allocated to a control group (with no compression to donor sites) or to an experimental group (with compression to donor sites) as the comparative treatment. Groups will be compared at baseline regarding the important prognostic indicators: donor site location, depth, size, age, and time since graft (5 days). The IPG treatment will be administered post-operatively (on day 5). Follow-up assessments and garment replacement will be undertaken fortnightly for a period of 2 months.

Discussion

This study focuses on a unique area of burns scar management using a low-pressure tubular support garment for the reduction of donor site scars. Such therapy specifically for donor scar management is poorly represented in the literature. This study was designed to test a potentially cost-effective scar prevention for patients with donor sites to the thigh. No known studies of this nature have been carried out to date, and there is a need for rigorous clinical evidence for low-pressure support garments for donor site scar minimisation.

Rapid onset of squamous cell carcinoma in a thin skin graft donor site

BACKGROUND

Squamous cell carcinomas are malignant tumours of epithelial origin that can appear on sites subjected to chronic inflammation after a period of several years. The rapid development of squamous cell carcinoma at the donor site for a thin skin graft is a rare and poorly understood situation.

PATIENTS AND METHODS

We report the case of a patient undergoing thin skin grafting to cover the area of removal of a vertex squamous cell carcinoma and in whom squamous cell carcinoma appeared at the donor site within 9 weeks.

DISCUSSION

In our case, we ruled out intraoperative contamination because two sets of surgical instruments were used. Given the number of cases reported in the literature, a chance event seems unlikely. The hypothesis of an acute inflammatory process caused by scarring of the thin skin graft site appears to us the most convincing. Development of cancer at the graft donor site may thus be added to the list of complications of thin skin grafting.

Donor-site closure using absorbable dermal staple for deep inferior epigastric artery perforator flaps: its efficacy and cosmetic outcomes

BACKGROUND

Surgeons tend to pay less attention to the donor site during breast reconstruction using deep inferior epigastric artery perforator flaps because attention is focused on microanastomosis and breast shaping. Therefore, donor site closure is typically performed by a secondary operator. We present consistently reduced operative times and improved scar quality using an absorbable dermal staple.

METHODS

Retrospective review was performed on 25 patients who were either standard suture controls (group I, n = 15) or received absorbable staples (group II, n = 10). Mean age, flap size, whole operative time, and length of hospital stay were collected. The donor site scar was evaluated by three plastic surgeons in a blinded manner using the modified Vancouver scar scale 6 months after surgery. Data were analyzed with the independent t test, and a p value ≤0.05 was considered significant.

RESULTS

No differences were detected between the groups for age, harvested flap size, or length of hospitalization. However, operative time was significantly longer in group I (1.07 ± 0.24 min/cm(2)) than that in group II (0.86 ± 0.16 min/cm(2), p = 0.015). The total scar assessment score was significantly lower in group II (3.8 3 ± 1.30) than that in group I (5.27 ± 1.83, p = 0.043).

CONCLUSIONS

Absorbable dermal stapling reduced operative time, compared to that of traditional suturing. In addition, scar quality from absorbable dermal staples was superior to that resulting from traditional sutures.

Donor site selection and clinical outcomes of nipple-areola skin-sparing mastectomy with immediate autologous free flap reconstruction: A single-institution experience

BACKGROUND

The objective of this study was to examine the clinical outcomes of immediate breast reconstruction using perforator flaps from different donor sites, and to characterize the trends among these flaps.

METHODS

We retrospectively reviewed 136 consecutive patients who underwent immediate breast reconstruction using free flaps after skin-sparing mastectomy (SSM) or nipple-sparing mastectomy (NSM). The whole breast was pathologically analyzed in 5-mm sections. Breast reconstruction was performed using the deep inferior epigastric perforator (DIEP) flap, gluteal artery perforator (GAP) flap, and posterior medial thigh perforator (PMTP) flap. Patient characteristics were compared among donor sites.

RESULTS

NSM was converted to SSM because of intraoperative subareolar tumor positivity in 7 of 107 patients. Eleven patients had positive margins in permanent sections. All but one patient had a positive horizontal margin in the peripheral direction. The 5-year recurrence-free survival rate was 91.9%. The locoregional recurrence rate was 5.1% with a mean follow-up observation period of 75 months. DEIP, GAP, and PMTP flaps were used in 64 (47.1%), 38 (27.9%), and 34 (25.0%) patients, retrospectively. DIEP flaps were used in older patients and those with a higher body mass index. GAP flaps were used in younger patients. DIEP and GAP flaps were used for larger breasts, and PMTP flaps for smaller breasts.

CONCLUSION

NSM or SSM with immediate perforator flap breast reconstruction is an oncologically acceptable surgical option. We believe that age, desire to have children, body mass index, and excised breast volume are valuable factors for selecting the optimal donor site.

Long-term effects of toe transfers on the donor feet

The purpose of this study was to assess the long-term consequences to the donor site of microvascular transfer of one or two toes. This was achieved retrospectively by patient-reported, clinician-based and functional testing. Weight-bearing radiographs were taken of both feet. Seventy-four patients (80 feet, 84 transferred toes) participated in this study. After a median of 16 years follow-up, most patients reported no or only minor complaints concerning the donor site. Cold intolerance and pain during exertion were the most commonly reported complaints. According to the two functional scores used, 92% of patients reported no or minor complaint and 83% of patients received a good result at the donor feet. Maintaining first ray alignment and avoiding early postoperative complications predicted a better outcome. Even though donor site ramifications should be expected after microvascular transfer of toes, patient satisfaction remains high.

Donor’s site evaluation after restoration with autografts or synthetic plugs in rabbits

AIM: To investigate donor site’s area histological and immunohistochemical knee cartilage appearances after resurfacing iatrogenic defects with biosynthetic plugs orautografts.

METHODS: Thirty New Zealand White rabbits were used in this study. A full-thickness cylindrical defect of 4.5 mm (diameter) × 7 mm (depth) was created with a hand drill in the femoral groove of every animal. In Group A (n = 10) the defect of the donor site was repaired with a biosynthetic osteochondral plug, in Group B (n = 10) with an osteochondral autograft, while in Group C (control group of 10) rabbits were left untreated.

RESULTS: Twenty-four weeks postoperatively, smooth articular cartilage was found macroscopically in some trocleas’ surfaces; in all others, an articular surface with discontinuities was observed. Twenty-eight out of 30 animals were found with predominantly viable chondrocytes leaving the remaining two -which were found only in the control group- with partially viable chondrocytes. However, histology revealed many statistical differences between the groups as far as the International Cartilage Repair Society (ICRS) categories are concerned. Immunofluoresence also revealed the presence of collagen II in all specimens of Group B, whereas in Group A collagen II was found in less specimens. In Group C collagen IIwas not found.

CONCLUSION: The matrix, cell distribution, subchondral bone and cartilage mineralization ICRS categories showed statistically differences between the three groups. Group A was second, while group B received the best scores; the control group got the worst ICRS scores in these categories. So, the donor site area, when repairing osteochondral lesions with autografting systems, is better amended with osteochondral autograft rather than bone graft substitute implant.

Female hair restoration

Female hair loss is a devastating issue for women that has only relatively recently been publicly acknowledged as a significant problem. Hair transplant surgery is extremely successful in correcting the most cosmetically problematic areas of alopecia. This article discusses the surgical technique of hair transplantation in women in detail, including pearls to reduce postoperative sequelae and planning strategies to ensure a high degree of patient satisfaction. A brief overview of some of the medical treatments found to be helpful in slowing or reversing female pattern hair loss is included, addressing the available hormonal and topical treatments.

Harvesting free abdominal perforator flaps in the presence of previous upper abdominal scars

PURPOSE

Subcostal scars pose a risk of upper abdominal flap ischaemia when raising a free abdominal flap. The aim of this study was to describe a clinical approach to increase flap reliability and donor site healing in the presence of transverse abdominal scars while harvesting lower abdominal free flaps.

METHODS

A total of 11 patients who had subcostal scars and one who had an extended subcostal scar (rooftop or chevron incision) underwent free abdominal flaps for breast reconstruction. Preoperative radiological imaging was used to evaluate the blood supply to the planned flaps. A classification of clinical approaches (I-IV) was used. When the cranial (the abdominal closure) flap width was equal to or greater than half length, a caudal (the breast) flap could safely be harvested (Type I); if not, the cranial flap was enlarged by more caudal flap planning (Type II), an oblique design of the free flap (Type III) or by lowering the free flap marking more distally (Type IV) with a sparing of the peri-umbilical perforators to preserve blood supply to the caudal (abdominal closure) flap.

RESULTS

Unilateral free deep inferior epigastric perforator (DIEP) and superficial inferior epigastric artery (SIEA) flaps were successfully harvested in eight and two cases, respectively. In two cases, a bipedicled DIEP/SIEA flap was harvested for unilateral breast reconstruction. Slight abdominal wound slough occurred in one patient; however, no ischaemia resulted in flaps or at donor sites.

CONCLUSIONS

Using a pragmatic approach to flap design, based on clinical classification, we have found that both flap and donor site morbidity can be avoided in patients who have previous upper abdominal scars.

Graft harvesting and management of the donor site

The strip technique remains the most popular method of harvesting grafts. The challenge in every patient is to maximize the number of grafts while minimizing the scar. Fortunately, there are many ways to ensure that the donor site will be inconspicuous. This article reviews the details of planning for follicle graft harvesting, including formulae for assessing scalp laxity and calculating strip dimensions. The procedure is discussed in detail, from preparation of the donor site and estimation of graft total through closure of the incision. The author presents his preferences for the technique with rationale and surgical tips.

A prospective, randomized, placebo controlled, double blind study of silicone gel in prevention of hypertrophic scar at donor site of skin grafting

Background:

Hypertrophic scarring at donor site of skin grafting is prevalent among Asians. The effectiveness of silicone gel in scar prevention may influence the surgeons and patients regarding its routine use during the postoperative period.

Aims and Objectives:

To study the efficacy of silicone gel in prevention of hypertrophic scars at donor site of skin grafting.

Design:

Prospective randomized placebo controlled double blind study.

Setting:

The study was conducted in the department of Plastic Surgery, Sri Venkateswara Institute of Medical Sciences (SVIMS) University, Tirupati, Andhra Pradesh, India from June 2007 to June 2009. Patients were recruited during follow-up in the OPD.

Materials and Methods:

The susceptibility to scar development varied among patients; therefore, donor site scars were divided into upper half and lower half. Two types of coded gel prepared by an independent pharmacist were used on either half. Thus, selection and assessment biases and confounders were eliminated.

Results:

100 scars in 50 patients were randomized into two arms, 50 control and 50 silicone gel. The median age was 25.5 years and there were 30 men (60%) and 20 women (40%). Thirty-seven patients (74%) had good compliance. The overall incidence of donor site hypertrophic scar was 94% (47 out of 50). At the second month postoperatively, the silicone gel scars were scored lower when compared with the control scars. The differences were statistically significant in all parameters, including pigmentation (P = 0.001), Vascularity (P = 0.010), pliability (P = 0.001), and height (P = 0.010).

Conclusion:

The effect of silicone gel in prevention of hypertrophic scar development in donor site scars is promising. Success of silicone gel in its prophylactic role will create its routine use in all types of surgery to minimize the formation of hypertrophic scars in the early postoperative period.

A systematic review of anterolateral thigh flap donor site morbidity

PURPOSE

The anterolateral thigh (ALT) flap is widely used in reconstruction. Its advantage over other flaps is its purported minimal donor site morbidity. The present systematic review summarizes the types of complications and their incidence with this flap. A secondary objective is to delineate factors that influence these complications and make recommendations to avoid them.

METHOD

Two independent assessors undertook a systematic review of the literature using multiple databases. All patients with ALT flap reconstruction for any defect were included. Donor site complications including lateral thigh paresthesia, musculoskeletal dysfunction, hypertrophic scarring, wound breakdown, infection, donor site pain, seroma, hematoma, compartment syndrome and muscle necrosis were extracted from identified articles and tabulated. Based on the number of pooled events and the number of cases performed, an incidence rate was calculated.

RESULTS

Forty-two relevant articles were identified that included 2324 flaps. Of the 2324 flaps, the majority were fasciocutaneous (n=737), and 1303 of the flaps were used in head and neck reconstruction. The incidence of complications were: lateral thigh paresthesia (24.0%); musculoskeletal dysfunction (4.8%); hypertrophic scarring or wound dehiscence (4.8%); donor site pain (3.3%); seroma (2.4%); infection (2.2%); hematoma (0.7%); compartment syndrome (0.09%); and partial muscle necrosis (0.09%).

CONCLUSION

Lateral thigh paresthesia is the most common complication. Severe complications such as compartment syndrome and muscle necrosis can occur, but are rare. Preservation of the lateral cutaneous nerve of the thigh, femoral motor nerve branches and deep fascia decreases the risk of complications. The degree of vastus lateralis disruption did not show a significant impact on musculoskeletal dysfunction.

A Clinical Study Comparing Helicoll with Scarlet Red and OpSite in the Treatment of Split Thickness Skin Graft Donor Sites-A Randomized Controlled Trial

Split thickness skin graft (STSG) is a key method in the reconstructive ladder for covering skin defects used widely by surgeons from all specialties. The donor site is often a source of delayed healing, associated with considerable pain and discomfort even more than the recipient wound. The aim of this prospective randomized controlled study was to compare Helicoll® (EnColl Corp., Fremont, CA, USA), a type I pure collagen dressing, to OpSite® (Smith & Nephew, USA) dressing and to Scarlet Red® (Kendall HealthCare, USA) dressing in the treatment of standardized STSG donor sites. Thirty patients, over a 3-month period, underwent various reconstructive procedures, necessitating the use of STSGs. Following a simple randomized clinical protocol, the analysis of data included donor site pain, healing time of the donor site, initial absorption of the applied dressing and rate of infection with the three different dressings to form the basis of this paper. Patients in the Helicoll group reported significantly less pain, less infection rate and required no dressing change when compared with the OpSite (Johnson & Johnson, Langhorne, PA, USA) or the Scarlet Red groups. Healing time of the donor site in the Helicoll group was shorter than that in the Scarlet Red group; however, it was comparable to the OpSite group. This study indicates that Helicoll, as a donor site dressing, is successful in providing pain-free mobility with a measurable healing rate.

Flap donor site size reduction with substratum horizontal mattress suture

BACKGROUND

Closure of donor site of the flap has special problems. Reduction of this site will decrease the morbidity of operation. In this study, we present our experience in donor site size reduction.

METHODS

Between 2006 and 2008, 15 patients with skin and soft tissue defects underwent operation. In all patients, coverage of defect was performed with various flaps. Substratum horizontal mattress suture was used to reduce donor site dimensions. In all 15 patients, size of the flaps, the defect after the flap elevation and the scar size were measured.

RESULTS

The mean size of the flap, the defect after flap elevation, and the scar after 3 months were 43.9 cm(2), 69.4 cm(2), and 32.2 cm(2), respectively. There was 46.5% reduction in the donor site after using this suture.

CONCLUSION

The substratum horizontal mattress suture was shown to de- crease the donor site dimensions and also its scar size in flap surgery. This suture is highly recommend in order to reduce donor site dimensions.
