The radial forearm free flap in orofacial reconstruction. Personal experience in 120 consecutive cases

Clinical outcomes of bilobed platysma myocutaneous flap technique with neck dissection in lower lip squamous cell carcinoma

BACKGROUND

Squamous cell carcinoma (SCC) in the lower lip is among the most frequently encountered types of cancer. As the size of this cancer increases, the need for reconstruction becomes evident, posing a significant challenge. Depending on the staging results in these patients, neck dissection may be recommended.

OBJECTIVE

This study aims to demonstrate the successful application or feasibility of our Bilobed Platysma Myocutaneous Flap technique in patients with lower lip SCC.

METHODS

The Bilobed Platysma Myocutaneous Flap was applied to all patients. Following TNM staging, supraomohyoid and/or radical neck dissection were performed. Surveys were conducted with the patients, and scoring was implemented based on the results for evaluation.

RESULTS

Between 2014 and 2018, 23 patients underwent treatment with this flap, and all flaps survived. Among these patients, bilateral supraomohyoid neck dissection was performed on 14, while modified radical neck dissection on one side and supraomohyoid neck dissection on the other side were conducted on the remaining 9 patients. Throughout the 5-year follow-up period, no recurrence was observed in the patients.

CONCLUSION

The combination of the Bilobed Platysma Myocutaneous Flap technique and neck dissection can be successfully employed in the reconstruction and treatment of lower lip cancers.

The fibula osteoseptocutaneous flap: evolution in concepts, techniques, and technologies during mandibular reconstruction - a review

The fibula-free flap has evolved from its initial description to be a reliable workhorse-free flap providing bone, soft tissue, and a reliable skin paddle. The senior author has been refining this technique since the mid-1980s and has personally performed over 950 hundred cases of the fibula-free flap. The following paragraphs detail an evolution in surgical concepts related to this technique's refinement and serves as a roadmap detailing contemporary mandibular reconstruction.

Comparing the Outcomes of Osteocutaneous Radial Forearm and Fibula Free Flaps in the Reconstruction of Mandibular Osteoradionecrosis

BACKGROUND

This study compares the outcomes of osteocutaneous radial forearm free flap (OC-RFFF) and fibula free flap (FFF) reconstruction of mandibular osteoradionecrosis (ORN).

METHODS

Retrospective review of patients undergoing OC-RFFF/FFF reconstruction for mandible ORN between 2005 and 2020 at a tertiary center. Patient characteristics, postoperative complications, and functional outcomes were evaluated using chi-squared and logistic regression analysis.

RESULTS

Fifty-six patients were included (OC-RFFF: 38; FFF: 18). Significantly more OC-RFFF patients had lateral mandible defects (94% vs. 61%, p = 0.0014). There were significantly more patients with exposed intraoral bone in the OC-RFFF group (23% vs. 0% p = 0.02), but no significant differences in hardware complications or flap failure. Donor site partial skin graft loss was more common in the FFF group (22% vs. 2.6%, p = 0.016), but no other significant differences in donor site morbidity were seen. Bivariable analysis showed no impact of flap type, tobacco/alcohol use, diabetes, or hypothyroidism on postoperative complications. Sixty percent of OC-RFFF, and 67% of FFF, patients resumed an oral diet after surgery. Oral diet was not impacted by flap type (OR = 0.769, 95% CI = 0.201-2.706, p = 0.688).

CONCLUSION

The OC-RFFF is an acceptable option in the reconstruction of ORN involving the lateral mandible, though there is increased risk of bone exposure. These findings can help guide surgeon selection of microvascular free flap donor sites and appropriate patient counseling.

"DO ONE, GET TWO": dual venous drainage of the radial forearm free flap by a single venous anastomosis

PURPOSE

The radial forearm free flap (RFFF) remains a workhorse in microsurgical reconstruction. Its failure is primarily due to problems with venous drainage; for this reason, controversy on venous anastomosis patterns still exists. This manuscript describes our experience in using a communicating vein to overcome the complications of venous drainage of the RFFF.

METHODS

Following a review of the vascular anatomy of the RFFF, we retrospectively review the use of the communicating vein and report our results, with the aim of overcoming the dichotomy "superficial versus deep venous system" and "single versus double anastomosis" and discussing the evidence of advantages in using a single microanastomosis with a communicating vein.

RESULTS

Our retrospective review included a total of 123 patients in which a RFFF was performed to reconstruct intraoral defects, performed with a single venous anastomosis using the communicating vein. Four patients (3.25%) required a return to theatre for revision of the venous anastomosis and one case resulted in flap failure due to arterial insufficiency (0.81%).

CONCLUSIONS

Our series highlights the constant presence of the communicating vein, although with variations of origin and course that did not preclude the possibility to correctly perform the anastomosis. Advantages of a single microanastomosis with the communicating vein include ease, speed, reliability and versatility in planning the anastomosis. Based on our results, the use of the communicating vein showed comparable and, in some cases, more favourable results when compared to venous anastomotic complications reported in the literature.

Rates of bone reabsorption and union in mandibular reconstruction using the osteocutaneous radial forearm free flap

BACKGROUND

Historical concerns over bone resorption and malunion of the osteocutaneous radial forearm free flap (OCRFFF) limited its widespread adoption for head and neck reconstruction, despite lack of outcomes data evaluating this notion.

METHODS

A retrospective cohort study was performed including patients 18 years or older who underwent reconstruction of the mandible using an OCRFFF. Linear modeling and logistic regression were used to evaluate the change in bone volume and union over time.

RESULTS

One hundred and twenty-one patients were included in the study. A mixed effects linear model incorporating age, sex, treatment type, and number of bone segments did not demonstrate a significant loss of bone volume over time. A logistic regression model identified lack of adjuvant treatment and time to be significantly associated with complete union.

CONCLUSION

This study supports that the OCRFFF is a stable form of osseus reconstruction for defects of the head and neck.

Outcomes of Single Anastomoses for Superficial and Deep-System Venous Drainage of Radial Forearm Free Flaps

Objective

Venous insufficiency occurs in radial forearm free flaps (RFFFs) when either the deep venous system (DVS) or superficial venous system (SVS) is used as the venous outlet. We report our experience using the antecubital perforating vein (APV) in a single-vessel anastomosis to the median-cubital or cephalic vein to drain both systems.

Study Design

Retrospective review.

Setting

Single, academic, tertiary care center.

Methods

Data were collected from 72 patients who underwent RFFF from October 2009 to January 2017. In all cases, DVS and SVS were dissected, and an APV single-vessel anastomosis was attempted.

Results

Anatomical variations precluded single-vessel anastomosis in 11 (15.3%) cases. In 61 (84.7%) cases, single-vessel anastomosis produced unobstructed drainage for DVS and SVS without intrinsic venous insufficiency. Venous thrombosis and total loss occurred in 2 (3.3%) and 1 (1.6%) patients, respectively. Proximal dissection of the cephalic vein addressed a vessel-depleted neck in 3 cases.

Conclusion

The antecubital perforating vein is present and functional in most patients, allowing for single anastomosis techniques for RFFF. Antecubital perforators capture DVS and SVS outflow through a single, extended venous pedicle, eliminating the risk of venous insufficiency and need for vein grafts.

A simple method for preconditioning radial forearm flaps in the case of an insufficient ulnar vascular supply: a retrospective clinical analysis

Due to its versatile applicability, many reconstructive surgeons use the radial forearm flap (RFF) as the first choice for soft tissue replacement. Donor site limitations of the flap arise with an insufficient blood supply along the ulnar artery. This study presents a simple and safe method for RFF preconditioning by recruitment of the deep palmar arch via the ulnar artery. Fourteen patients scheduled for RFF surgery between 2013 and 2018 showed an insufficient vascular supply according to the Allen test, which was confirmed by digital subtraction angiography (DSA). These 14 patients underwent temporary ligature of one or both radial arteries with elastic vessel loops under local anaesthesia and continuous pulse oximetry. A control DSA was performed about 24hours later in 10 of the 14 patients. Recruitment of the blood supply along the enlarged ulnar artery or reanimated collaterals was confirmed in all 10 patients. No local complications such as ischemia of the hand were seen. All flaps could be harvested regularly and were used for different reconstructive purposes. This simple technique may help to overcome vascular limitations of the RFF via the rapid, efficient, and reliable recruitment of the biological vascular reserve. Within the limits of a case series, this procedure appears practicable and safe.

Factors associated with skin graft take in fibula and radial forearm free flap donor sites

LEARNING OBJECTIVES

Identify factors associated with skin graft take in fibula free flaps (FFF) and radial forearm free flaps (RFFF) donor sites.

STUDY OBJECTIVES

To determine which factors are associated with decreased skin graft take at the donor site in FFF and RFFF in head and neck patients.

DESIGN

Retrospective Chart Review Case Series.

SETTING

Multicenter Tertiary Care.

METHODS

A multicenter retrospective review was performed at three institutions identifying patients who underwent free tissue transfer, specifically either FFF or RFFF, between 2007 and 2017. Patient demographics, medical history, and social history were examined including age, gender, BMI, smoking status, diabetes and preoperative anticoagulation use. Preoperative, intraoperative data, and postoperative data were also examined including tourniquet use, type of flap, area of skin graft, if the skin graft had a donor site or if it was taken from the flap, wound NPWT use, cast use, use of physical therapy, DVT prophylaxis, limb ischemia, heparin drip, and postoperative aspirin use. Statistical analysis was used to determine which factors were significantly associated with skin graft take.

RESULTS

1415 patients underwent a forearm or fibula flap and 938 patients underwent split-thickness skin graft. Of these, 592 patients had sufficient information and were included in the final analysis. There were 371 males and 220 females. The average age was 55.7. Complete skin graft take was seen in 480 patients (81.1%). On univariate analysis, patients with diabetes (p = .003), type of flap (fibula p < .001), skin graft area (p = .006), tourniquet use (p = .003), DVT prophylaxis (p = .008) and casting (p = .003) were significantly associated with decreased skin graft take rate. In a multivariate analysis, diabetes (OR 2.17 (95%CI 1.16-3.98)), fibula flaps (OR 2.86 (95%CI 1.79-4.76)), an increase in skin graft area (OR 1.01 (95%CI 1.01-1.01)), post-operative aspirin (OR 2.63 (95%CI 1.15-5.88), and casting (OR 2.94 (95%CI 1.22-7.14)) were associated with poor rates of skin graft take.

CONCLUSION

Several factors affect skin graft take rate and should be considered when performing a skin graft for a donor site defect.

Prevalence of Accessory Branches and Other Anatomical Variations in the Radial Artery Encountered during Radial Forearm Flap Harvest: A Systematic Review and Meta-analysis

Background Harvest of the radial forearm flap (RFF) for reconstructive surgery is proceeded by the Allen test to assess for adequate contralateral perfusion of the hand, yet the Allen test may fail to detect anatomical variations in the radial artery such as aberrant branching. Therefore, the goal of this study was to systematically review the literature regarding anatomical abnormalities of the radial artery that can affect flap harvest and to perform a meta-analysis to estimate the prevalence of such abnormalities.

Methods A systematic review of the literature was conducted using five online databases to identify all instances of radial artery anatomical variations. Abstracts were reviewed and categorized into either (1) large cohort studies of anatomical variations identified by angiogram or (2) case reports specifically mentioning anomalous or accessory branches of the radial artery. Data from the large cohort studies were included in a random effect meta-analysis to estimate the prevalence of such variations.

Results Eighteen angiogram cohort studies containing a total of 18,115 patients were included in the meta-analysis. Accessory branches were the least common anatomical variant reported, with an estimated average prevalence of 0.5%. Prevalence estimates for more common anatomical variants, including radial artery loops (0.9%), stenosis (1.3%), hypoplasia (1.9%), tortuosity (4.3%), and abnormal origin (5.6%), were also calculated. Thirteen case reports detailing anomalous branches of the radial artery were identified, seven of which involved accessory branches encountered during RFF harvest with no incidence of flap loss.

Conclusion Radial artery accessory branches are exceedingly rare, but the prevalence of other anatomical variations that can affect harvest of the RFF warrants consideration. We recommend surgeons consider comprehensive screening prior to RFF harvest to avoid intraoperative discovery of anatomical variants and suggest a low threshold for repeat perfusion testing intraoperatively if radial artery accessory branches are encountered.

Tourniquet use and factors associated with hematoma formation in free tissue transfer

PURPOSE

Our objective was to understand which variables are associated with hematoma formation at both the donor and recipient sites in head and neck free tissue transfer and if hematoma rates are affected by tourniquet use.

METHODS

Patients were identified who underwent free tissue transfer at three institutions, specifically either a radial forearm free flap (RFFF) or a fibula free flap (FFF), between 2007 and 2017. Variables including use of tourniquet, anticoagulation, treatment factors, demographics, and post-operative factors were examined to see if they influenced hematoma formation at either the free tissue donor or recipient site.

RESULTS

1410 patients at three institutions were included in the analysis. There were 692 (49.1%) RFFF and 718 (50.9%) FFF. Tourniquets were used in 764 (54.1%) cases. There were 121 (8.5%) hematomas. Heparin drips (p < .001) and DVT prophylaxis (p = .03) were significantly associated with hematoma formation (OR 95% CI 12.23 (4.98-30.07), 3.46 (1.15-10.44) respectively) on multivariable analysis.

CONCLUSIONS

Heparin Drips and DVT prophylaxis significantly increased hematoma rates in free flap patients while tourniquets did not affect rates of hematoma.

Revisiting radial forearm free flap for successful venous drainage

Tissue defect reconstruction using radial forearm free flap (RFFF) is a common surgical technique whose success or failure is mainly dependent on venous drainage. RFFF has two major venous outflow systems, superficial and deep vein. Drainage methods include combining both systems or using one alone. This review aims to recapitulate the vascular anatomy and network of RFFF as well as shed light on deep vein as a reliable venous drainage system. We also discuss basic evidence for and advantages of single microanastomosis with coalesced vein to overcome technical difficulties associated with the deep vein system.

Osteocutaneous radial forearm free flap in nonmandible head and neck reconstruction

BACKGROUND

The osteocutaneous radial forearm free flap (RFFF) is a versatile flap primarily used to reconstruct composite defects involving the mandible. The purpose of this study was to describe our experience with this flap for nonmandible reconstruction.

METHODS

All patients undergoing nonmandible osseous reconstruction with free-tissue transfer were reviewed. Patients with osteocutaneous RFFF reconstructions were evaluated. The retrospective review of all osteocutaneous RFFFs was performed from 1998 to 2014.

RESULTS

One hundred forty-two nonmandible osseous reconstructions were performed. Twenty-five patients underwent nonmandible osteocutaneous RFFF reconstruction. Eleven patients failed previous nonmicrovascular reconstruction. Reconstruction was for defects of the: palatomaxillary complex (n = 15), orbitomaxillary complex (n = 4), nasomaxillary complex (n = 4), larynx (n = 1), and clavicle (n = 1). There were no flap compromises. Postoperative complications included: 2 partial intraoral dehiscences; 1 recipient-site infection; and 1 seroma. Eight reconstructions required secondary procedures to improve functional and/or cosmetic outcomes.

CONCLUSION

The osteocutaneous RFFF is a robust flap that can be used to reconstruct composite defects involving bone and soft-tissue beyond the mandible.

The use of the radial styloid in the extended osteocutaneous radial forearm free flap

BACKGROUND

The osteocutaneous radial forearm free flap (OC-RFFF) remains a useful tool in head and neck reconstruction; however, it can be challenging to harvest sufficient bone for large reconstructions. The extended OC-RFFF is a modification that involves harvest of the distal border of the radius to the tip of the styloid. This increases the length of the bone flap by 2 cm to 3 cm, and the inherent contour of the styloid can be used to reconstruct the anterior curvature of the mandible or maxilla without additional osteotomies that may reduce blood supply.

METHODS

The key steps in harvesting the extended OC-RFFF are described. Six patients with mandibular or maxillary defects underwent reconstruction with the extended OC-RFFF. Patient data including demographics, defect features, reconstruction details and outcomes were collected.

RESULTS

Of the six patients who underwent the extended OC-RFFF, four had mandibular reconstruction and two had maxillary reconstruction. Two patients underwent reconstruction for osteoradionecrosis and the remainder for malignant disease. The average patient age at the time of surgery was 64.5 years. The length of radius harvested ranged from 8 cm to 14 cm (mean 9.7 cm). Two of six patients required a single osteotomy of their bone flap. Donor site complications included partial skin graft loss in 50% and a radius fracture in two patients. Recipient site complications included one patient with intraoral plate exposure. There have been no cases of nonunion.

CONCLUSIONS

The extended OC-RFFF was a safe and reliable option for bony reconstruction in the head and neck.

Single Superficial versus Dual Systems Venous Anastomoses in Radial Forearm Free Flap: A Meta-Analysis

Background

The radial forearm free flap (RFFF) has been widely used with increasing frequency in head and neck reconstruction following extirpative surgery. The controversy of the venous anastomoses patterns still exists. Thus, we conducted a meta-analysis to assess the relationship between the venous anastomoses patterns and venous compromise.

Methods

MEDLINE, PubMed, Web of Science, and Wanfang databases were searched for studies reporting the different venous anastomoses patterns of the RFFF. A meta-analysis was conducted using the random effects models. Publication bias and sensitivity analysis were also assessed.

Results

6 studies with 992 cases were included in this meta-analysis. The dual anastomosis group tended to have a lower incidence of venous compromise (RR = 1.39). However, the difference was not statistically significant (95%CI: 0.59, 3.24).

Conclusions

This meta-analysis indicated that performing dual venous anatomoses consisting of superficial and deep systems conferred a tendency of the reduction with regard to venous compromise.

Free Flaps in a Resource Constrained Environment: A Five-Year Experience-Outcomes and Lessons Learned

Introduction. Free flap surgery is a routine procedure in many developed countries with good surgical outcomes. In many developing countries, however, these services are not available. In this paper, we audit free flaps done in a resource constrained hospital in Kenya. Objective. This is a five-year audit of free flaps done in a tertiary hospital in Kenya, between 2009 and 2014. Materials and Methods. This was a prospective study of patients operated on with free flaps between 2009 and 2014. Results. A total of one hundred and thirty-two free flaps in one hundred and twenty patients were performed during the five-year duration. The age range was eight to seventy-two years with a mean of 47.2. All the flaps were done under loupe magnification. The overall flap success rate was eighty-nine percent. Conclusion. Despite the many limitations, free flaps in our setup were successful in the majority of patients operated on. Flap salvage was noted to be low due to infrequent flap monitoring as well as unavailability of theatre space. One therefore has to be meticulous during surgery to reduce any possibilities of reexploration.

Safe osteocutaneous radial forearm flap harvest with prophylactic internal fixation

We studied the efficacy of prophylactic plate fixation technique and a modified harvest of the osteocutaneous radial forearm free flap (OCRFFF) to minimize the incidence of postoperative donor radius pathological fracture. We retrospectively studied of the first 70 consecutive patients undergoing OCRFFF harvest by the University of Kansas Head and Neck Microvascular Reconstruction Team. Mean follow-up was 13 months. One of two patients undergoing OCRFFF harvest without prophylactic fixation developed a pathological radius fracture. The 68 subsequent OCRFFF patients underwent prophylactic fixation of the donor radius, and none developed a symptomatic radius fracture. Five of 68 patients did have a radiographically visible fracture requiring no intervention. The plate fixation technique was further modified to exclude monocortical screws in the radius bone donor defect (subsequent 39 patients), without any further fractures detected. One patient required forearm hardware removal for an attritional extensor tendon tear. The described modified OCRFFF harvest and prophylactic plate fixation technique may eliminate postoperative pathological fracture of the donor radius. Donor morbidity is similar to that of the fasciocutaneous radial forearm free flap , affording safe use of OCRFFF in head and neck reconstruction.

Free flap reconstruction of self-inflicted submental gunshot wounds

In this study, we review outcomes for 15 patients with self-inflicted submental gunshot wounds requiring free flap reconstruction. Patients presented to two tertiary care centers over a 7-year period. Mean age was 46 years (range, 16 to 76 years), 67% (n = 10) had a psychiatric history, and four were known to abuse illicit substances. Patients with oromandibular involvement required on average a total of 2.8 procedures, and those with midface (3.7) or combined defects (6) required more total procedures (p = 0.21). Donor sites included osteocutaneous radial forearm (n = 8), fibula (n = 4), fasciocutaneous radial forearm (n = 5), and anterior lateral thigh (n = 1). Median length of hospitalization was 8 days. Overall complication rate was 33% (n = 5), and included hematoma (n = 1), fistula (n = 1), and mandibular malunion (n = 2). Most patients were able to tolerate a regular or soft diet (92%), maintain oral competency (58%), and demonstrate intelligible speech (92%) at a median time to follow-up of 12 months. Despite the devastating nature of this injury, free flap reconstruction of self-inflicted submental gunshot wounds results in acceptable functional results for the majority of patients.

Comparison of sensory recovery at the subfascial and suprafascial donor sites of the free radial flap

The radial flap may be raised using a subfascial or suprafascial approach. The latter donor site is associated with fewer healing complications. We retrospectively evaluated the quality of sensory recovery within two comparable groups of 30 patients with subfascial and suprafascial donor sites. When considering the two groups, two-point discrimination was the modality most commonly reduced, with 97% of patients in both groups having reduced sensation in at least one anatomical zone. Sensation of sharp touch was most often lost; 90% in the subfascial and 83% in the suprafascial groups lost sensation in at least one anatomical zone. Roughly half the patients had reduced perception of light touch (43% and 50%), whilst perception of heat (27% and 17%) and cold (33% and 27%) were lost least often. At least one modality in at least one anatomical zone was lost or reduced in all patients, and roughly two-thirds (73% and 63%) had a reduction in 3 or more. The only significant difference between the donor and non-donor arms was reduced perception of sharp touch in the anterior forearm in both groups (p<0.001). Perception at the two sites (including the anatomical snuff box) was similar except for superior thenar palmar light touch (p=0.015) in the suprafascial group, which may indicate injury to the thenar cutaneous sensory branches during subfascial dissection.

Osteocutaneous radial forearm free flaps: prophylactic fixation of donor site using locking plate augmented with mineral cement

Prophylactic plating of donor site in osteocutaneous radial forearm free flaps have demonstrated improvement in fracture rates. Previous series used conventional plating systems which rely on plate-bone friction forces to generate stability and can result in iatrogenic fractures if not accurately contoured. Locking plates have superior stability and do not require contouring. This retrospective series reports our experience using locking plate fixation augmented with calcium phosphate mineral cement. Twenty patients' records were reviewed; 13 were alive and reviewed clinically. Mean radiological follow-up was 28.2 months. Two deceased patients had donor site fractures diagnosed on the first postoperative radiograph. These fractures were related to technical fixation errors and failure to apply correct locking fixation principles. None of the other patients with proper locking fixation had fractures or metalwork related complications. We believe that locking fixation augmented with mineral cement can provide more biological stability and enhance restoration of bone structural strength.

Transaxillary-subclavian transfer of pedicled latissimus dorsi musculocutaneous flap to head and neck region

Free-tissue transfer is the reconstruction of choice for most head and neck defects. However, pedicled flaps are also used, especially in high-risk patients and after failure of a free flap. The aim of this study was to compare transaxillary-subclavian pedicled latissimus dorsi musculocutaneous (PLDMC) flap, pectoralis major musculocutaneous flap, and free-tissue transfer for head and neck reconstruction in American Society of Anesthesiologists grades II and III patients. During the last 4 years, PLDMC flap with a modified transaxillary-subclavian route for transfer to the neck was used in 8 patients, pectoralis major musculocutaneous flap was used in 7 patients, and free flaps were used in 12 patients for head and neck reconstructions. These 3 methods were compared regarding the flap dimensions, complications, flap outcome scores, hospitalization time, and cost of the treatment. Mean age of the patients, mean American Society of Anesthesiologists scores, mean dimensions of the flaps, and mean hospitalization time did not differ significantly among the 3 groups. Regarding the operation time, flap complications, outcomes, and cost of total treatment, although statistically not significant, PLDMC group offered the fastest reconstruction with highest flap outcome scores and minimum cost. Free-tissue transfer is the procedure of choice especially for functional reconstruction of head and neck region. Occasionally, there exist cases in whom a pedicled flap could offer a safer option. The PLDMC flap transferred via the transaxillary-subclavian route may be preferred than, with advantages including increased arc of rotation, safer pedicle location, shorter duration of the procedure, and reduced complication rates and costs.

Lower lip reconstruction with neck flaps as a salvage procedure

There are many surgical reconstructive techniques after lower lip ablation. As the lower lip defect gets larger, the required reconstructive techniques become more complex. Despite the indication of free flaps, some situations require local flaps for reconstruction. These situations may be donor and/or recipient vessel problems or systemic disorders of the patient. In this article, a total lower lip reconstruction technique using the neck skin was described. The technique was applied successfully in 2 cases. An acceptable cosmetic result was obtained, and there were no early or late surgical complications in 2 years' follow-up. The patients were satisfied with the results. Lower lip reconstruction with the neck flaps must be kept in mind as a quicker alternative and a salvage method when the free flaps cannot be applied.

No reduction in complication rate by stay in the intensive care unit for patients undergoing surgery for head and neck cancer and microvascular reconstruction

BACKGROUND

The aim of this prospective cohort study was to determine whether an immediate postoperative period of deep sedation and artificial respiration in an intensive care unit (ICU) leads to fewer complications and a reduced failure rate of microvascular flaps compared with a situation in which patients are allowed to breathe spontaneously without sedation in a recovery room.

METHODS

Each group comprised 50 patients. General medical complications and flap donor and recipient site complications were documented.

RESULTS

Significantly, more patients had problems with weaning from ventilation in the ICU group (p = .022). More cases of respiratory insufficiency (p = .240) and pneumonia (p = .081) occurred in the ICU group compared with the recovery room group without statistically significant differences. The number of flaps lost was comparable in both groups (p = .646).

CONCLUSIONS

Admission to an ICU did not reduce complications after microvascular reconstruction and, therefore, has only to be considered for selected cases.

Dealing with aberrant vessels in radial forearm flaps - report of a case and review of literature

INTRODUCTION

Anomalies of the radial artery are uncommon. A brief tabulated review of the literature is presented.

CASE REPORT

We report a rare anomaly of the forearm vascular anatomy we encountered when elevating a radial forearm free flap. This is a previously unreported anatomical variation. The radial artery divided into medial and lateral branches (accompanied by their respective venae commitantes) about 1.5 cm below the bifurcation of the brachial artery. The skin paddle was predominantly supplied by the aberrant medial branch and was raised on this branch along with its venae commitantes up to the point of division.

CONCLUSION

This case highlights the need for vigilance when raising free flaps and the techniques employed to avoid compromising both limb and skin paddle perfusion.

The Transverse Radial Artery Forearm Flap

BACKGROUND

In an attempt to improve the versatility of the radial forearm flap, a new design was developed: the transverse radial artery forearm flap.

METHODS

The transverse radial artery forearm flap is designed elliptically in the distal palmar forearm with the long axis oriented transversely parallel to the wrist. The donor defect is closed by a V-shaped flap, which is elevated as a fasciocutaneous flap based on the ulnar artery by V-Y advancement. This second flap allows defect coverage without the need for a skin graft. From March of 1994 to February of 2005, the authors treated 39 patients with this flap. Free flaps were used in 36 patients and three patients were operated on with reverse pedicled flaps.

RESULTS

Twenty-five patients had head and neck defects, 11 patients had defects of the distal foot or great toe, and three patients had hand defects. In 13 cases, an osteocutaneous flap was elevated, and three flaps were transferred as sensate flaps. Maximum flap dimensions were 10 x 6 cm. The longest vascular pedicle in this series was 20 cm. All flaps survived. Except for two cases of delayed healing, no complications occurred at the donor site.

CONCLUSIONS

The transverse radial artery forearm flap is more versatile than the conventional radial flap, with the additional advantage of a long vascular pedicle. Its design allows for harvest of a piece of radial bone, which is pedicled on a completely different portion of the radial artery than the skin paddle. Thus, the setting of the bony portion can be chosen liberally. Donor-site morbidity is reduced, and the result is aesthetically pleasing.

Radial forearm free flap for reconstruction of the oral cavity: clinical experience in 55 cases

OBJECTIVE

Since the advent of modern microvascular techniques, the radial forearm free flap (RFFF) has become a reliable method for reconstruction of defects within the oral cavity. The purpose of the present study was to evaluate our experience with the use of the RFFF for the reconstruction of oral cavity defects after tumor resection.

STUDY DESIGN

During a 9-year period, 103 consecutive patients were treated in our department for the reconstruction of oral defects after tumoral ablation by means of microvascularized free flaps. Fifty-five patients were reconstructed by means of the RFFF. Patients were treated for benign (n = 1) and malignant (n = 54) entities. All the patients underwent an abdominal split-thickness skin graft for the closure of the donor site.

RESULTS

Fifty-five patients underwent reconstruction by means of the RFFF after resection of the oral cavity. Squamous cell carcinoma was present in 54 patients. A mean age of 55.5 years was observed (range 16-78). Thirty-nine patients (70.9%) were men and 16 (29.1%) women. Primary reconstruction was achieved in 52 patients (96.3%). A fasciocutaneous graft was used in all of the cases, with a mean size of 7.39 x 5.17 cm. The mean flap ischemic time was 56.02 minutes. During the immediate follow-up period, revision of the vascular anastomosis was necessary in 18.9% of the cases owing to flap ischemia.

CONCLUSION

Our results revealed that the RFFF is a reliable method for reconstructing a wide range of oral cavity defects with an acceptable low morbidity rate. It provides adequate bulkiness and pliability, resulting in adequate reconstruction of a wide variety of defects within the oral cavity.

Long-Term Results of Free Radial Forearm Flap Used for Oral Reconstruction: Functional and Histological Evaluation

PURPOSE

The aim of this study was to evaluate the radial forearm flap with regard to recovery of sensory function, general performance status, cutaneous blood flow and histological observations.

PATIENTS AND METHODS

Thirty patients (23 male and 7 female) with oral carcinoma underwent immediate reconstruction with radial forearm flap after ablative surgery and returned for evaluation. Interviews were conducted to assess the degree of articulation and mastication.

RESULTS

Sensory function tests suggested the restoration of cutaneous sensibility of the forearm flap. Histological findings indicated mucosa-like changes of flaps about 10 months after reconstruction. The clarity of conversation recovered favorably in most patients. However, the degree of recovery was generally related to the time after surgery.

CONCLUSION

The radial forearm flap is a unique flap with specific characters that allowed for best available functional reconstruction of the oral cavity in terms of restoration of sensation, performance, and histological changes to adapt to the new oral environment.
