Aesthetic outcome and oncological safety of nipple-areola complex replantation after mastectomy and immediate breast reconstruction

Immediate breast reconstruction (IBR) has become an established procedure for women necessitating mastectomy. Traditionally, the nipple-areola complex (NAC) is resected during this procedure. The NAC, in turn, is a principal factor determining aesthetic outcome after breast reconstruction, and due to its particular texture and shape, a natural-looking NAC can barely be reconstructed with other tissues. The aim of this study was to assess the oncological safety as well as morbidity and aesthetic outcome after replantation of the NAC some days after IBR. Retrospective analysis of 85 patients receiving 88 mastectomies and IBR between 1998 and 2007 was conducted. NAC (n=29) or the nipple alone (n=23) were replanted 7 days (median, range 2-10 days) after IBR in 49 patients, provided the subareolar tissue was histologically negative for tumour infiltration. Local recurrence rate was assessed after 49 months (median, range 6-120 months). Aesthetic outcome was evaluated by clinical assessment during routine follow-up at least 12 months after the last intervention. Malignant involvement of the subareolar tissue was found in eight cases (9.1%). Patients qualifying for NAC replantation were in stage 0 in 29%, stage I in 15%, stage IIa in 31%, stage IIb in 17% and stage III in 8%. Total or partial necrosis occurred in 69% and 26% if the entire NAC or only the nipple were replanted, respectively (P<0.01). Depigmentation was seen in 52% and corrective surgery was done in 11 out of 52 NAC or nipple replantations. Local recurrence and isolated regional lymph node metastasis were observed in one single case each. Another 5.8% of the patients showed distant metastases. We conclude that the replantation of the NAC in IBR is oncologically safe, provided the subareolar tissue is free of tumour. However, the long-term aesthetic outcome of NAC replantation is not satisfying, which advocates replanting the nipple alone.

Evaluation of late results in breast reconstruction by latissimus dorsi flap and prosthesis implantation

BACKGROUND: Breast reconstruction by latissimus dorsi myocutaneous flap in combination with a prosthesis is a widely used, well-established procedure. Short- and medium-term evaluation after this procedure is well described in the literature, but there have been no evaluations of the late course (over 10 years) published until now. METHODS: In a retrospective study, 68 patients operated on by means of this technique at the authors' institution from 1981 to 1993 resulting in a minimal follow-up of 10 years were included. Patients were invited to an interrogation, clinical examination, and photographic documentation (n = 51). Incidence of late flap or prosthesis-related complications, number of and indications for corrective procedures, and the correlation of the patients' subjective judgment and objective results in the late course have been the main interest of the authors' survey. RESULTS: The authors found that 50 percent of the patients needed a late reoperation for change or removal of the prosthesis. Seven (10 percent) of 68 patients needed a definitive removal of the implant in the late course. Assessment of the photographic documentation of the late result by four nonprofessionals showed that the objective aesthetic results of a considerable number of the authors' reconstructions were not sufficient. CONCLUSION: The procedure combines two basic techniques of reconstructive surgery, the soft-tissue restoration by a pedicled flap as the autologous reconstructive component and the volume reconstruction by prosthesis. Therefore, these patients are subject to a cumulation of the basic morbidity of the two techniques. The authors conclude that the indication for this procedure should be restricted to patients not qualifying for "pure" reconstructive techniques.

Outcome analysis of breast reconstruction with free transverse rectus abdominis musculocutaneous (TRAM) flaps

QUESTIONS UNDER STUDY: With the reduction in breast cancer mortality in recent years the aesthetic outcome after treatment has gained increasing attention. The aim of this study was to assess the outcome quality of our single institution concept of free TRAM flap breast reconstruction with the aim of providing data to assist the patient's decision-making when breast reconstruction is an option. PRINCIPLES/METHODS: Thirty-two consecutive patients receiving immediate (n = 14) or delayed (n = 18) breast reconstruction with free transverse rectus abdominis musculocutaneous (TRAM) flaps were included. The selection of patients was based on their own wish and the availability of abdominal tissue, without excluding patients at risk for wound healing complications. Patient data were assessed prospectively and the aesthetic outcome was rated after the final result had been achieved. RESULTS: Ten patients sustained wound healing complications (4 of 9 smokers, 8 of 16 patients with a BMI over 25 kg/m2), 8 of them requiring revisional surgery. An average of 1.06 corrective procedures were performed per patient. The aesthetic outcome was judged to be good by 20 patients, fair by 5 and poor by 1 patient who sustained severe tissue loss. CONCLUSIONS: Our results revealed that a large measure of satisfaction is achievable from breast reconstruction with free TRAM flaps, in spite of the invasive nature of the procedure and the inclusion of patients at risk for wound healing complications. These data may be used in the decision-making process by patients eligible for breast reconstruction after mastectomy.

To evaluate safety and fertility outcome after assisted conception in patients who were treated conservatively for a borderline ovarian tumor (BOT).

Combined bone and soft-tissue augmentation surgery in temporo-orbital contour reconstruction

Temporal hollowing due to temporal muscle atrophy after standard skull base surgery is common. Various techniques have been previously described to correct the disfiguring defect. Most often reconstruction is performed using freehand molded polymethylmethacrylate cement. This method and material are insufficient in terms of aesthetic results and implant characteristics. We herein propose reconstruction of such defects with a polyetheretherketone (PEEK)-based patient-specific implant (PSI) including soft-tissue augmentation to preserve normal facial topography. We describe a patient who presented with a large temporo-orbital hemangioma that had been repaired with polymethylmethacrylate 25 years earlier. Because of a toxic skin atrophy fistula, followed by infection and meningitis, this initial implant had to be removed. The large, disfiguring temporo-orbital defect was reconstructed with a PEEK-based PSI. The lateral orbital wall and the temporal muscle atrophy were augmented with computer-aided design and surface modeling techniques. The operative procedure to implant and adopt the reconstructed PEEK-based PSI was simple, and an excellent cosmetic outcome was achieved. The postoperative clinical course was uneventful over a 5-year follow-up period. Polyetheretherketone-based combined bony and soft contour remodeling is a feasible and effective method for cranioplasty including combined bone and soft-tissue reconstruction of temporo-orbital defects. Manual reconstruction of this cosmetically delicate area carries an exceptional risk of disfiguring results. Augmentation surgery in this anatomic location needs accurate PSIs to achieve satisfactory cosmetic results. The cosmetic outcome achieved in this case is superior compared with previously reported techniques.

The extended diep flap: extending the possibilities for breast reconstruction with tissue from the lower abdomen

The classical DIEP-flap is considered state-of-the-art in microsurgical autologous breast reconstruction. Some patients may require additional volume to match the contralateral breast. This quality control study prospectively evaluates the feasibility and outcome of a surgical technique, which pursues the volumetric augmentation of the DIEP-flap by harvesting of additional subscarpal fat tissue cranial to the classical flap border.

Incorporation of a preexisting scar in the star-flap technique for nipple reconstruction

This report describes the authors' currently favored method of nipple reconstruction in cases of a pre-existing scar on the breast mound that passes through the intended site of nipple reconstruction.

Secondary breast reconstruction with deepithelialized free flaps from the lower abdomen for intractable capsular contracture and maintenance of breast volume

Although surgical techniques and the quality of mammary prostheses have been improved significantly in recent years, capsular contracture attendant on prosthetic mammary reconstruction remains a major flaw. Although rarely, some patients are confronted with recurrent and intractable capsular contractures with resultant breast deformity, even after multiple attempts at capsulectomies and implant exchange. Patients with recurrent capsular contracture often do not want replacement with a new prosthesis, but desire the maintenance of their breast volume with a safe alternative. In an attempt to maintain breast volume and to improve the aesthetic appearance, secondary breast reconstruction using bilateral deepithelialized free flaps from the lower abdomen was performed in a series of seven patients. Three bilateral muscle-sparing TRAM flaps, two bilateral DIEP flaps, one bilateral SIEA flap, one unilateral SIEA flap, and one unilateral DIEP flap (a total number of 14 flaps) were used following implant removal, total capsulectomy, and prophylactic subcutaneous mastectomy. The early postoperative course was uneventful, and all flaps survived completely with no complications. There were no donor-site problems, except in one patient (case 5), who had partial skin necrosis of the abdominal flap. The long-term results (mean follow-up: 4.8 years) demonstrated an aesthetically satisfactory appearance of the breasts, with no major donor-site problems. Several advantages, as well as drawbacks, are highlighted with this technique.

Lung volume reduction surgery versus conservative treatment in severe emphysema

Lung volume reduction surgery (LVRS) has been proposed for patients with severe emphysema to improve dyspnoea and pulmonary function. It is unknown, however, whether prognosis and pulmonary function in these patients can be improved compared to conservative treatment. The effect of LVRS and conservative therapy were compared prospectively in 57 patients with emphysema, who fulfilled the standard criteria for LVRS. The patients were divided into two groups according to their own decision. Patients in group 1 (n=29, eight females, mean+/-SEM 58.8+/-1.7 yrs, forced expiratory volume in one second (FEV1) 27.6+/-1.3% of the predicted value) underwent LVRS. Patients in group 2 (n=28, five females, 58.5+/-1.8 yrs, FEV1 30.8+/-1.4% pred) preferred to postpone LVRS. There were no significant differences in lung function between the two groups at baseline; however, there was a tendency towards better functional status in the control group. The control group had a better modified Medical Research Council (MMRC) dyspnea score (3.1+/-0.15 versus 3.5+/-0.1, p<0.04). Model-based comparisons were used to estimate the differences between the two groups over 18 months. Significant improvements were observed in the LVRS group compared to the control group in FEV1, total lung capacity (TLC), Residual volume (RV), MMRC dyspnea score and 6-min walking distance on all follow up visits. The estimated difference in FEV1 was 33% (95% confidence interval 13-58%; p>0.0001), in TLC 12.9% (7.9-18.8%; p>0.0001), in RV 60.9% 32.6-89.2%; p>0.0001), in 6-min walking distance 230 m (138-322 m; p<0.002) and in MMRC dyspnoea score 1.17 (0.79-1.55; p<0.0001). In conclusion, lung volume reduction surgery is more effective than conservative treatment for the improvement of dyspnoea, lung function and exercise capacity in selected patients with severe emphysema.

Accelerated partial breast irradiation with interstitial brachytherapy as second conservative treatment for ipsilateral breast tumour recurrence: multicentric study of the GEC-ESTRO Breast Cancer Working Group

PURPOSE To analyse the clinical outcome after salvage lumpectomy and multi-catheter brachytherapy (MCB) for ipsilateral breast tumour recurrence (IBTR). MATERIAL AND METHODS Between 09/00 and 09/10, 217 patients presenting an IBTR underwent lumpectomy and MCB (low, pulsed, or high-dose rate). Survival rates without second local recurrence (2nd LR), distant metastasis (DM), and overall survival (OS) were analysed as well as late effects and cosmetic results. Univariate and multivariate analyses (MVA) based on IBTR data were performed to find prognostic factors for 2nd LR, DM, and OS. RESULTS Median follow-up after the IBTR was 3.9 years [range: 1.1-10.3]. Five and 10-year actuarial 2nd LR rates were 5.6% [range: 1.5-9.5] and 7.2% [range: 2.1-12.1], respectively. Five and 10-year actuarial DM rates were 9.6% [range: 5.7-15.2] and 19.1% [range: 7.8-28.3], respectively. Five and 10-year actuarial OS rates were 88.7% [range: 83.1-94.8] and 76.4% [range: 66.9-87.3], respectively. In MVA, histological grade was prognostic factor for 2nd LR (p=0.008) and OS (p=0.02); while tumour size was prognostic factor for DM (p=0.03). G3-4 complication rate was 11%. Excellent/good cosmetic result was achieved in 85%. CONCLUSION This study suggests that in case of IBTR, lumpectomy plus MCB is feasible and effective in preventing 2nd LR with an OS rate at least equivalent to those achieved with salvage mastectomy.
