Sensitivity of breasts reconstructed with the autologous latissimus dorsi flap

A Comparative Analysis of Sensory Return in Delayed-Immediate Versus Immediate Neurotized Deep Inferior Epigastric Perforator Flap Breast Reconstruction

BACKGROUND

Breast reconstruction patients who anticipate adjuvant radiation are not suitable candidates for immediate deep inferior epigastric perforator (DIEP) flap reconstruction due to the risk of flap fibrosis, shrinkage, and fat necrosis. Rather, many of these patients undergo delayed-immediate, or "babysitter," reconstruction, where a tissue expander is placed first as a temporizing measure during adjuvant therapy before definitive flap reconstruction. In this study, we aim to compare sensory changes in delayed-immediate to immediate DIEP flap patients.

METHODS

Ninety-one patients, including 26 patients (46 breasts) with "babysitter" procedures and 65 patients (120 breasts) with immediate DIEP flaps, were prospectively identified at their preoperative visit. For both cohorts, baseline level (t = 0) is defined as before mastectomy.

RESULTS

"Babysitter" patients underwent final-stage neurotized flap reconstruction on average at 12 months after initial tissue expander placement (range, 3-18 months). At 18 month after mastectomy (6 months after DIEP), delayed-immediate patients had comparable sensitivity measurements as immediate DIEP flap patients in all regions of the breast (P > 0.05). For delayed immediate patients, at 18 months postoperatively, sensitivity measurements were comparable with baseline levels only in the outer superior, outer medial, and outer lateral regions of the breast (P > 0.05). At 24 months postoperatively, cutaneous thresholds were comparable with baseline in all regions of the breast except the inner inferior region (P > 0.05), following a similar sensory recovery trajectory as immediate DIEP flap patients.

CONCLUSIONS

In patients who undergo "babysitter" procedures, the combination of sensory return from the native mastectomy skin flap along with the neurotized DIEP flap yields sensory recovery comparable with immediate DIEP flap patients after definitive flap reconstruction. When final-stage flap reconstruction occurs by 12 months after mastectomy, sensation can return beginning 24 months postoperatively, or even sooner in some regions of the breast.

A Pilot Study Comparing Sensation in Buried Versus Nonburied Deep Inferior Epigastric Perforator Flaps

BACKGROUND

Neurotized deep inferior epigastic perforator (DIEP) flaps have been shown to improve sensory recovery after mastectomy and reconstruction. With the recent trend toward nipple-sparing mastectomies, sensation likely originates within the buried DIEP flap and then innervates the breast skin. In contrast, for patients undergoing skin-sparing mastectomies, the DIEP flap skin is preserved, brought up to the surface, and directly innervated. In this study, we aim to evaluate inner breast region sensation between patients whose DIEP flap is buried and whose DIEP flap skin is brought to the surface.

METHODS

Seventy patients who underwent mastectomy with immediate reconstruction using the DIEP flap were prospectively identified. Of these, 60 patients underwent nipple-sparing mastectomy with buried DIEP flap reconstruction while 10 patients underwent skin-sparing mastectomy with nonburied DIEP flap reconstruction. Patients in both cohorts received nerve grafting using the 70 × 1-2-mm Avance Nerve Graft in identical fashion. Sensitivity evaluation was performed in five inner breast regions (corresponding to the nonburied DIEP flap area).

RESULTS

In the buried DIEP cohort, at 6 months postoperatively, there was a statistically significant difference in inner breast region sensitivity measurements compared with baseline levels (P < 0.001). In contrast, in the nonburied DIEP cohort, at 6 months postoperatively, sensation in the inner breast region was comparable with preoperative baseline levels (P = 0.236). At 24 months postoperatively, inner breast region sensitivity measurements in both cohorts were comparable with preoperative baseline measurements (P > 0.05).

CONCLUSIONS

Neurotized DIEP flap skin raised directly to the surface confers earlier sensory recovery than buried DIEP flaps. In patients who undergo skin-sparing mastectomies with nonburied DIEP flap reconstruction, they can expect significantly better sensation in the inner regions of the breast at 6 months postoperatively. In patients who undergo nipple-sparing mastectomies with buried DIEP flap reconstruction, they can expect sensation in the inner breast to return to preoperative baseline levels at a later time point-beginning as early as 24 months postoperatively.

Scarless Composite Breast Reconstruction Utilizing an Advancement Skin Flap, Loops, and Lipofilling

BACKGROUND

Autologous fat grafting has gained popularity in breast reconstructive surgery. To further increase the breast volume and provide a reliable breast shape, a skin flap can be advanced from the upper abdomen and lateral thorax to the breast.

OBJECTIVES

The aim of this study was to propose a method of breast reconstruction utilizing the principles of power-assisted liposuction and lipofilling (PALL) for breast matrix dissociation applied through infiltration, tunnelization, extensive undermining and lipofilling, in combination with loops (PALLL) to recruit a vascularized flap to reshape the breast.

METHODS

A prospective study was performed from January 2014 to January 2019. Demographic data, surgical procedure information (including volumes of the recruited advancement flap and lipofilling, and stages of lipofilling), and complication data were collected. Patient-reported outcomes, including satisfaction and well-being, were measured by a questionnaire.

RESULTS

In total, 37 women (41 breasts) underwent breast reconstruction by PALLL with an average follow-up of 26 months. The mean age of the patients was 54 years, and their mean BMI was 29 kg/m2. The mean recruited flap volume was 197 mL, and the mean lipofilling volumes were 153 mL for the first session, 190 mL for the second session, and 110 mL for the third session. Nine patients needed 3 sessions, 27 patients 2 sessions, and 1 patient only 1 session. Overall, 94% of patients were satisfied with their breast shape. All patients reported sensitive breasts. There were minimal complications.

CONCLUSIONS

Breast reconstruction with PALLL is a minimally invasive alternative to reconstructing and reshaping sensate breasts in which a vascularized skin flap recruited by loops from breast surroundings is combined with fat grafting. This approach provides long-term shape stability with minimal scarring and low complication rates.

Risk and protective factors affecting sensory recovery after breast reconstruction

Background

Although loss of sensation in patients with breast cancer after mastectomy followed by breast reconstruction is an important factor affecting patients’ quality of life, the mechanism of sensory recovery is still unclear. Our study aimed to identify variables that affect sensory recovery, especially pain, in reconstructed breasts.

Methods

All patients with breast cancer who underwent mastectomy followed by immediate breast reconstruction, including nipple reconstruction or areolar tattooing, were included in this study. Sensation was evaluated in the nipple as an endpoint of sensation recovery of the whole breast. Patients rated pain severity using a 3-point verbal rating scale (VRS): grade 0, no pain; grade 1, mild to moderate pain; and grade 2, severe pain. The VRS was assessed by a single experienced plastic surgeon.

Results

In the univariate analysis, the odds ratio (OR) for sensation recovery was 0.951 for age (P=0.014), 0.803 for body mass index (P=0.001), 0.996 for breast volume before surgery (P=0.001), 0.998 for specimen weight after mastectomy (P=0.040), and 1.066 for the period between mastectomy and sensory assessment (P=0.003). In the multivariate analysis, the variables that showed a significant effect were age (OR, 0.953; P=0.034), the period between mastectomy and sensory assessment (OR, 1.071; P=0.006), and reconstruction using abdominal tissue instead of prosthetic reconstruction (OR, 0.270; P=0.004).

Conclusions

Based on our results, it can be inferred that aging has a negative impact on the recovery of sensation, breast sensation improves with time after surgery, and the recovery of sensation is better in prosthetic reconstruction.

[Breast reconstruction with the autologous latissimus dorsi flap]

Amongst various techniques of breast reconstruction, Autologous Latissimus Dorsi (ALD) flap without breast implant is the newest technique that took advantage of recent improvement during the last decade. Surgical procedure is well standardized, and allows to harvest various fat areas attached to the muscle, to obtain an autologous reconstruction. Thoracodorsal pedicle is steady and makes ALD the most reliable flap that can be used in several indications, especially when DIEP or TRAM flap are inappropriate. Lipomodeling of the cleavage is performed during the first surgery. Additionnal lipomodeling is performed in the whole reconstructed breast area at 2 months to get the expected volume. In some cases, two lipomodelings may be required. Advantages of ALD flap are numerous such as its reliability, its trophicity, and a very low complications rate. After a learning curve, drawbacks are well controlled, since quilting suture of the donor site helped to reduce drastically seroma rate. Finally, ALD flap became the best technique, and the most used in our team for autologous breast reconstruction, and surpassed abdominal flaps such as TRAM flap or DIEP flap.

Herpes Zoster Lesions on Reconstructed Breast Skin: Rare Objective Proof of Reinervation

Blazed up Herpes zoster lesions have been described in very few patients after free and pedicled flap transfer for reconstructive purpose. Although sensory recovery after flap reconstructions has been studied extensively most studies addressed subjective perceptions of sensation. Objective investigations of spontaneous reinervation of free and pedicled flaps are rare. We would like to present a witnessed herpes zoster infection of a latissimus dorsi skin flap 2 years after breast reconstruction.

[Correction of thoraco-mammary deformity of Poland syndrome]

Breast deformity of Poland syndrome is a malformation known to be difficult to treat. Numerous descriptions of surgical corrections have been published but none achieved to correct severe cases before description of lipomodeling technique. The aim of this article is to present thoraco-mammary deformity of Poland syndrome, corrections techniques already available and therapeutical indications in primary and secondary cases. Constant anomaly of Poland syndrome is agenesis of sternocostal part of pectoralis major muscle but other muscular anomalies can be associated. Skin and glandular anomalies present with a fine skin and an absent or hypoplasic subcutaneous fat with a glandular hypoplasia of various degree. Osteo-cartilaginous anomalies can be associated in very severe cases. Clinical sign of Poland syndrome is forced adduction maneuver highlighting pectoralis major agenesis. Functional impact of the deformity is low but psychological and psychosocial implications can be very important, supporting an early surgical correction. Therapeutic means are various and accurate descriptions are given in this article: thoracic bony reconstruction, thoracic implant made of silicone elastomer, breast implant, skin expansion, latissimus dorsi pedicled flap, free flaps, breast lipomodeling, breast-pectoralis flap. Principles of each technique are described and balanced with their actual use in this malformation. Indications have been completely modified these last years due to lipomodeling contribution which represented a huge step in this deformity treatment. In our practice, if autologous reconstruction with lipomodeling is possible, we choose this solution at first. In case of severe thoracic deformity, a silicone elastomer implant made with the help of computed assisted conception can be an important adjunct, mainly by thin young man. In secondary cases, if implant is well tolerated, we found logical to stay in the same reconstruction path and do one or two sessions of lipomodeling in order to improve reconstruction. If implant tolerance is low and skin very thin at risk of exposure, we do recommend a conversion of implant reconstruction to autologous reconstruction. In conclusion, thoraco-mammary deformities of Poland syndrome are rare and hard to treat and should be managed by well trained and experimented surgeons. Breast lipomodeling is a huge step in the treatment of these deformities and should be regarded, in our opinion, as first line treatment if fat deposits are sufficient. In case of low fat provisions or in the thin young man, composite techniques should be used with silicone elastomer implant.

Pilot study of breast sensation after breast reconstruction: evaluating the effects of radiation therapy and perforator flap neurotization on sensory recovery

BACKGROUND

Some sensation to the breast returns after breast reconstruction, but recovery is variable and unpredictable. We primarily sought to assess the impact of different types of breast reconstruction [deep inferior epigastric artery perforator (DIEP) flaps versus implants] and radiation therapy on the return of sensation.

METHODS

Thirty-seven patients who had unilateral or bilateral breast reconstruction via a DIEP flap or implant-based reconstruction, with or without radiation therapy (minimum follow-up, 18 months; range, 18-61 months) were studied. Of the 74 breasts, 27 had DIEP flaps, 29 had implants, and 18 were nonreconstructed. Eleven breasts with implants and 10 with DIEP flaps had had prereconstruction radiation therapy. The primary outcome was mean patient-perceived static and moving cutaneous pressure threshold in nine areas. We used univariate and multivariate analyses to assess what independent factors affected the return of sensation (significance, P < 0.05).

RESULTS

Implants provided better static (P = 0.071) and moving sensation (P = 0.041) than did DIEP flaps. However, among irradiated breasts, skin over DIEP flaps had significantly better sensation than did that over implants (static, P = 0.019; moving, P = 0.028). Implant reconstructions with irradiated skin had significantly worse static (P = 0.002) and moving sensation (P = 0.014) than did nonirradiated implant reconstructions.

CONCLUSIONS

Without irradiation, skin overlying implants is associated with better sensation recovery than DIEP flap skin. However, with irradiation, DIEP flap skin had better sensation recovery than did skin over implants. Neurotization trended toward improvement in sensation in DIEP flaps.

Current indications for and comparative analysis of three different types of latissimus dorsi flaps

BACKGROUND

Free tissue transfer with lower abdominal flaps for autologous breast reconstruction is not suitable for all patients. The latissimus dorsi (LD) musculocutaneous flap is an alternative, effective method for both immediate and delayed breast reconstruction.

OBJECTIVES

The authors assess their experience with LD flaps for breast reconstruction, including indications for patient selection, donor site choice, aesthetic outcomes, complications, and patient satisfaction.

METHODS

Charts for all patients who underwent breast reconstruction with one of three types of LD myocutaneous flaps during a three-year period at a single institution were retrospectively reviewed. Patients (n = 82) were divided into three groups: (1) 35 patients received a standard LD myocutaneous flap with implant, (2) 18 patients underwent a muscle sparing LD flap procedure with implant, and (3) 29 patients had an autologous LD flap. A questionnaire was administered to assess flap and donor site complications, aesthetic outcomes, patient satisfaction, and shoulder function.

RESULTS

Flap complications occurred in 13 patients (15%). Donor site complications occurred in 24 patients (28%), mostly consisting of back seroma with the autologous LD flap. There was no significant difference in shoulder range of motion or muscle strength between the operated and unoperated sides. Patient satisfaction was high in all three study groups.

CONCLUSIONS

The LD is a safe, versatile, and reproducible technique for breast reconstruction. The procedure benefits from ease of flap harvesting and setting and may provide satisfactory results in diverse patients, including those for whom an abdominal flap is neither indicated nor feasible. .

[Oncologic, functional, and aesthetics results; evaluation of the quality of life after latissimus dorsi flap breast reconstruction. About a retrospective series of 450 patients]

Retrospective assesssment from 1998 to 2005 from women who have a breast reconstruction by autologus latissimus flap or by latissimus flap and silicone breast implant for differed breast reconstruction (DBR) or mastectomy and immediate breast reconstruction (MIBR).

PATIENTS AND METHOD

Analysis of oncologic results on 450 patients. Analysis of aesthetic, functional results and of quality of life by an anonymous questionnaire in the non progressive patients (407): 263 appraisable answers (13 DBR, 127 MIBR). Middle age: 49.8 years.

RESULTS ONCOLOGIC

Forty-three patients (9.5%) had a relapse of their disease, 33 patients died (7.2%). The relapse of the disease was done in the form of metastasis alone: 29 (67.4%), metastasis and local recurrence: three (7%), local recurrence only: four (9.3%), not specified: seven (16.3%). The average time between the breast reconstruction and the relapse was 18.25±15.4 months.

AESTHETIC RESULTS

The overall assessment is of 7.68/10. There is no statistical difference between immediate reconstruction and delayed reconstruction. A total of 11.2% patients considered it to be bad (<5/10). The symmetry between the two breasts in time is of 6.6/10 and 19.9% patients considered it to be bad (<5/10). The scar ransom, considered to be most important, is mostly in the back (4.1/10) then on the controlateral breast and then the breast reconstruction. This ransom is not easily acceptable in 15 to 20% of the patients.

FUNCTIONAL RESULTS

The discomfort and the pain prevail above all in the back (3.56 and 2.59/10). Weaker symptoms in the event of immediate reconstruction than delayed reconstruction. We noted that 77.2% had kinesitherapy after surgery and 18.9% continues to have kinesitherapy, long time after surgery, mainly for massages of the back. The handicap is considered to be overall low 2.5/10 but 10% of the patients keep a feeling of important handicap (>7.5/10).

QUALITY OF LIFE RESULTS

Seventy-one of the patients are serene. The discomfort to wear a bathing suit or to look at bare-chested is low (2.59 and 2.44/10). However 8.9% are in a very discomfort to see themselves bare-chested and 17.6% to show themselves to their spouse, with an impact on their emotional and sexual life in 36.4% of the cases. There is no significant difference between MIBR and DBR but on the other hand according to the judgement of the woman of her aesthetic result. A total of 95.7% do not regret having made this breast reconstruction.

CONCLUSION

This study makes it possible to concentrate on the group of non satisfied patient for better determining the causes and the improvements of the surgical techniques to bring but also the overall surgical management of the patient even if most of the patients were mainly satisfied with their breast reconstruction.

Sensation Following Immediate Breast Reconstruction with Implants

Sensation is a neglected aspect of the outcome of breast reconstructions with implants. The aim of this prospective study was to evaluate the cutaneous somatosensory status in breasts following mastectomy and immediate reconstruction with permanent adjustable prostheses and to analyze the patients' subjective experience of the sensation. Twenty-four consecutive patients diagnosed with invasive or in situ breast carcinoma were examined preoperatively and 2 years after mastectomy and reconstruction, for assessment of perception thresholds for touch, cold, warmth, and heat pain above and below the areola. Von Frey filaments and a Peltier element-based thermode were used. The patients completed a questionnaire concerning their experienced sensation in the reconstructed breast. Using quantitative somato-sensory testing, the sensation to all the examined modalities was significantly impaired compared to preoperatively. Most affected was the area above the areola. Patients given postoperative radiotherapy (n = 9) did not differ from those without radiotherapy (n = 15) regarding any of the modalities. All patients reported reduced sensation in the reconstructed breast compared to that preoperatively. Twenty-three patients stated that the reconstructed breast felt different from the other breast; nevertheless 16 reported that the reconstructed breast felt like a real breast. The study revealed sensation impairment following mastectomy and immediate reconstruction with implants. Patients should be informed about this effect preoperatively to allow adequate expectations regarding the sensation outcome. However, two-thirds of the study patients considered that the reconstructed breast felt like a real breast, which must be one of the main purposes of a breast reconstruction.

Lipomodeling of Poland's syndrome: a new treatment of the thoracic deformity

BACKGROUND

The severe forms of Poland's syndrome, with thoracic deformity, were until now very difficult to treat, with treatment involving complex surgery and implant insertion. Results were, in general, inadequate and the appearance unnatural. Our experience with fat transfer for breast reconstruction led us to propose reconstruction of the breast and thorax by serial fat transfer.

METHODS

Our patient had a very severe form of Poland's syndrome with agenesis of the pectoralis major and latissimus dorsi muscles and lack of fusion of the fourth costal arch. She was treated by fat transfer, or lipomodeling. Lipomodeling was developed in our team in 1998 to augment breast volume after autologous latissimus dorsi flap reconstruction. Because this technique and use of an implant were not possible, we attempted reconstruction by repeated lipomodeling. The patient underwent five sessions at intervals of a few months, the first in August 2001.

RESULTS

With 6 years of follow-up, the aesthetic, functional, and psychological results exceeded our expectations. In five sessions we were able to reconstruct a breast of natural shape, sensitivity, and consistency, and which was totally accepted by the patient. Mammography, echography, and MRI 1 year later showed a normal breast of fatty type.

CONCLUSION

Lipomodeling in Poland's syndrome is technically feasible. This original description of treatment of the severest form of Poland's syndrome, with impressive results and at the cost of limited constraints and scar sequelae, opens new perspectives and suggests extensive potential applications of lipomodeling in all disciplines related to the breast.

Triamcinolone reduces seroma re-accumulation in the extended latissimus dorsi donor site

BACKGROUND

The incidence of donor site seroma after autologous latissimus dorsi (ALD) breast reconstruction is in the order of 70%. In the majority of cases the seroma recurs following an initial aspiration. We designed a double-blind randomised controlled trial to test the hypothesis that an intracavity injection of the anti-inflammatory corticosteroid triamcinolone would inhibit seroma re-accumulation.

METHODS

We recruited 52 ALD breast reconstructions in 49 patients, of whom 41 involved immediate reconstruction and 11 delayed reconstruction. Patients exhibiting seromas at their first postoperative visit were randomised to receive either intracavity triamcinolone 80 mg (Group A, n=29) or saline (Group B, n=23), following seroma aspiration. We recorded the incidence of wound complications, total time (days) and number/volume of subsequent aspirations to dryness.

RESULTS

Triamcinolone significantly reduced the need for any further aspiration (A=16/29, B=22/23), total number of aspirations (A: median=1, interquartile range=0-1; B: median=4, interquartile range=2-5; P<0.0001), total volume aspirated (A: median=30 ml, interquartile range=0-80; B: median=325 ml, interquartile range=199-550; P<0.0001), and total time to dryness (A: median=12 days, interquartile range 7-17; B: median=37 days, interquartile range 20-49; P<0.0001). The incidence of adjuvant chemotherapy (A=16/29, B=9/23) and radiotherapy (A=16/29, B=10/23) was similar, and there was no effect upon donor site complications (Group A=4/29, Group B=2/23, P=0.725). The mean follow-up time for patients in the steroid group was 264 days compared to 254 days for those in the placebo group. Steroid injections were well tolerated, and there were no infective complications.

CONCLUSION

Following initial aspiration, intracavity injection of triamcinolone significantly reduced seroma re-accumulation after ALD breast reconstruction.

Alternatives aux prothèses mammaires

The use of implants is a basic technique in breast reconstruction after mastectomy, for the correction of breast abnormalities or even more in aesthetic breast augmentation. However, especially in difficult cases, implants can have inconveniences and insufficiencies (poor natural aspect, necessity of replacement, capsular contracture). To mitigate these, numerous alternatives were developed. These autologous techniques use mainly the pedicled or free musculocutaneous flaps, which were at first used in breast reconstruction. Their indications were then widened in surgery of breast abnormalities and in aesthetic surgery of the breast. Main alternatives, described, in the breast implants are envisaged by clarifying their advantages, inconveniences, indications and contraindications. The current place of the fat grafting in breast plastic surgery is defined by taking into account the most recent data.

Impact of skin-sparing mastectomy with immediate reconstruction and breast-sparing reconstruction with miniflaps on the outcomes of oncoplastic breast surgery

BACKGROUND

The aim of this study was to compare the outcomes of skin-sparing mastectomy (SSM) with immediate myocutaneous flap reconstruction and partial mastectomy with latissimus dorsi miniflap reconstruction (LDMF) for breast cancer.

METHODS

Some 106 disease-free patients (57 SSM, 49 LDMF) who had breast reconstruction between 1991 and 1999 participated in this retrospective review. The mean duration of follow-up was 42 (range 6-102) months. Measured outcomes included surgical complications, functional disability, cosmetic result and psychological morbidity.

RESULTS

SSM outcomes were less favourable than LDMF outcomes with regard to postoperative complications (14 versus 8 per cent), further surgical interventions (79 versus 12 per cent), nipple sensory loss (98 versus 2 per cent), restricted activities (73 versus 54 per cent) and cosmetic outcome by panel assessment. Anxiety about residual cancer and ease of breast self-examination were similar in both groups.

CONCLUSION

LDMF was associated with fewer adverse surgical and physical sequelae than SSM, without compromising local control or cosmetic outcome. Both operations were associated with low psychological morbidity.

Breast reconstruction using the sensate latissimus dorsi musculocutaneous flap

The authors performed immediate breast reconstruction on four patients using a sensate latissimus dorsi musculocutaneous flap accompanied by neurorrhaphy during the past 6 years. In the neurorrhaphy, the lateral cutaneous branch of the dorsal primary divisions of the seventh thoracic nerve, which controls the sensation of the myocutaneous flap, was anastomosed to the lateral cutaneous branch of the fourth intercostal nerve, which controls the sensation of the breast. The subjects consisted of four patients whose postoperative follow-up period was 14 to 29 months, with an average of 19.3 months. The control subjects consisted of 10 cases with a latissimus dorsi musculocutaneous flap whose sensory nerve had not been reconstructed (postoperative follow-up period, 15 to 49 months; average, 26.9 months). The sensory examination included tests of touch, pain, and temperature. The innervated musculocutaneous flap sensation showed gradual recovery at about 6 months after surgery and reached the value of the normal side after about 1 year. In the control subjects, the recovery was gradual after more than 1 year and reached the value of the normal side in only some of the control subjects. On the basis of these findings, the authors consider the present technique to be useful for the recovery of sensation in immediate breast reconstruction.
