Free Flaps in Patients with Advanced Arteriosclerosis of the Tibial Vessels: Mini Vein Graft to the Peroneal Artery.

Lower extremity reconstruction with free flaps in patients with only peroneal artery runoff remains a challenge. Here, we present a novel technique for reconstruction of medial defects in the distal leg using a medial approach to the peroneal artery and a short interposition vein graft anastomosed end to side to the peroneal artery. A retrospective, single-center study was performed including all patients who underwent lower extremity reconstruction with free flaps anastomosed to the peroneal artery using a mini vein graft from November 2020 to March 2022. The primary outcome measure was limb salvage. Secondary endpoints were flap survival and postoperative complications. Seven patients received lower extremity free flap reconstruction with a mini vein graft to the peroneal artery. Flap loss rate was 0%. Limb salvage was achieved in five patients (71%). At 6-month follow-up, all patients were ambulatory. One patient died 1 month after surgery due to heart failure. Mini vein graft to the peroneal artery allows reliable and safe free flap reconstruction of distal leg defects in patients with only peroneal artery runoff.

Improving quality of life after breast cancer: a comparison of two microsurgical treatment options for breast cancer-related lymphedema (BCRL).

PURPOSE: Vascularized lymph node transfer (VLNT) entails the autologous relocation of lymph nodes to a lymphedematous region of the body, whereas lymphaticovenous anastomosis (LVA) creates a direct bypass between the lymphatic and venous system. Both techniques are meant to lastingly bolster the local lymphatic drainage capacity. This study compared safety and effectiveness of VLNT and LVA in patients with chronic breast cancer related lymphedema (BCRL). METHODS: A retrospective cohort study was conducted using data from our encrypted database composed of patients with chronic BCRL who were treated with either VLNT or LVA and had a minimum follow-up of two years. Patient-specific variables analyzed included pre- and postoperative arm circumferences, lymphedema stages and postoperative complications. RESULTS: A total of 105 patients met the inclusion criteria, of which 96 patients demonstrated a complete follow-up period of two years. The VLNT group displayed larger preoperative circumferential measurements, evident in both in the isolated examination of the affected arm, as well as when adjusted for the contralateral unaffected arm. Significant reduction in arm volume was achieved by both groups. However, VLNT demonstrated superior relative reduction rates than LVA, neutralizing any significant arm size disparities after 24 months. Surgery duration was slightly longer for VLNT than LVA. Postoperative complications, predominantly minor, were exclusively observed in the VLNT group. CONCLUSIONS: Both VLNT and LVA offer significant improvement for patients suffering from chronic BCRL. VLNT shows an even greater potential for improvement in more severe cases of BCRL, but involves a higher risk for (mostly minor) complications.

Rhinosurgery during and after the COVID-19 Pandemic: International Consensus Conference Statement on Preliminary Perioperative Safety Measures.

BACKGROUND: The coronavirus disease of 2019 (COVID-19) pandemic has widely affected rhinosurgery, given the high risk of contagion and the elective nature of the aesthetic procedure, generating many questions on how to ensure safety. The Science and Research Committee of the Rhinoplasty Society of Europe aimed at preparing consensus recommendations on safe rhinosurgery in general during the COVID-19 pandemic by appointing an international panel of experts also including delegates of The Rhinoplasty Society. METHODS: A Zoom meeting was performed with a panel of 14 international leading experts in rhinosurgery. During 3.5 hours, four categories of questions on preoperative safety measures in private practice and outpatient clinics, patient assessment before and during surgery, and legal issues were presented by four chairs and discussed by the expert group. Afterward, the panelists were requested to express an online, electronic vote on each category and question. The panel's recommendations were based on current evidence and expert opinions. The resulting report was circulated in an iterative open e-mail process until consensus was obtained. RESULTS: Consensus was obtained in several important points on how to safely restart performing rhinosurgery in general. Preliminary recommendations with different levels of agreement were prepared and condensed in a bundle of safety measures. CONCLUSION: The implementation of the panel's recommendations may improve safety of rhinoplasty by avoiding operating on nondetected COVID-19 patients and minimizing severe acute respiratory syndrome coronavirus 2 virus spread in outpatient clinics and operating rooms.

The Value of Morphometric Measurements in Risk Assessment for Donor-Site Complications after Microsurgical Breast Reconstruction.

Microsurgical abdominally-based reconstruction is considered the gold standard in autologous breast reconstruction. Despite refined surgical procedures, donor-site complications still occur, reducing patient satisfaction and quality of life. Recent work has outlined the potential of morphometric measurements in risk assessment for postoperative hernia development. With rising demand for personalised treatment, the goal of this study was to investigate their potential in risk assessment for any donor site complication. In this retrospective cohort study, 90 patients were included who each received microsurgical breast reconstruction at the hands of one surgeon between January 2015 and May 2017. Donor-site complications formed the primary outcome and were classified according to Clavien-Dindo. Morphometric measurements were taken on a routinely performed computed tomographic angiogram. Complications occurred in 13 of the 90 (14.4%) cases studied. All patients who developed any type of postoperative donor site complication had a history of abdominal surgery. The risk of postoperative complications increased by 3% with every square centimetre of omental fat tissue (OR 1.03, 95% CI 1.00-1.06, and p-value = 0.022). Morphometric measurements provide valuable information in risk assessment for donor-site complications in abdominally-based breast reconstruction. They may help identify personalised reconstructive options for maximal postoperative patient satisfaction and quality of life.

What Happened after the Poly Implant Prothèse Recall? A Prospective Cohort Study of 808 Implants into the Predictive Value of Implant Rupture on Postexchange Complications.

BACKGROUND: Problems with a variety of breast implants have emerged with consequences for patients' health and safety. The authors' goal was to follow up on their Poly Implant Prothèse patients after their implant exchange. METHODS: This single-center, single-surgeon, prospective cohort study lasted from 2012 until 2017. Implant size, implantation interval, surgical details, and complications were registered. The Clavien-Dindo classification was used to grade postoperative complications. Logistic regression was used to investigate whether rupture, interval between implantation and explantation, and new implant size were predictors of postexchange complications. RESULTS: The authors explanted 808 implants in 404 patients. The rupture rate was 30.9 percent per patient and 20.2 percent per implant. The capsular contracture rate at the time of exchange was low, with 1.86 percent of implants and 2.7 percent of patients; 97.8 percent of patients elected implant exchange and only 2.2 percent just wanted their implants removed. The mean follow-up after implant exchange was 5.2 years, with the last mandatory outpatient appointment usually being scheduled 6 to 12 months after implant exchange. The authors found that 74 patients (18.3 percent) and 124 implants (15.3 percent) had postexchange complications, the majority of them minor (83 percent Clavien-Dindo grade I). Patients with a ruptured implant at the time of exchange were significantly more likely to develop postexchange complications than were patients without rupture. CONCLUSIONS: This is the first study providing such a complete long-term postexchange follow-up of a single surgeon's Poly Implant Prothèse implant cohort. Implant rupture at the time of exchange had a high predictive value for postexchange complications in the authors' series of 808 implants and 404 Poly Implant Prothèse recall patients. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Engineered autologous cartilage tissue for nasal reconstruction after tumour resection: an observational first-in-human trial.

BACKGROUND: Autologous native cartilage from the nasal septum, ear, or rib is the standard material for surgical reconstruction of the nasal alar lobule after two-layer excision of non-melanoma skin cancer. We assessed whether engineered autologous cartilage grafts allow safe and functional alar lobule restoration. METHODS: In a first-in-human trial, we recruited five patients at the University Hospital Basel (Basel, Switzerland). To be eligible, patients had to be aged at least 18 years and have a two-layer defect (≥50% size of alar subunit) after excision of non-melanoma skin cancer on the alar lobule. Chondrocytes (isolated from a 6 mm cartilage biopsy sample from the nasal septum harvested under local anaesthesia during collection of tumour biopsy sample) were expanded, seeded, and cultured with autologous serum onto collagen type I and type III membranes in the course of 4 weeks. The resulting engineered cartilage grafts (25 mm × 25 mm × 2 mm) were shaped intra-operatively and implanted after tumour excision under paramedian forehead or nasolabial flaps, as in standard reconstruction with native cartilage. During flap refinement after 6 months, we took biopsy samples of repair tissues and histologically analysed them. The primary outcomes were safety and feasibility of the procedure, assessed 12 months after reconstruction. At least 1 year after implantation, when reconstruction is typically stabilised, we assessed patient satisfaction and functional outcomes (alar cutaneous sensibility, structural stability, and respiratory flow rate). FINDINGS: Between Dec 13, 2010, and Feb 6, 2012, we enrolled two women and three men aged 76-88 years. All engineered grafts contained a mixed hyaline and fibrous cartilage matrix. 6 months after implantation, reconstructed tissues displayed fibromuscular fatty structures typical of the alar lobule. After 1 year, all patients were satisfied with the aesthetic and functional outcomes and no adverse events had been recorded. Cutaneous sensibility and structural stability of the reconstructed area were clinically satisfactory, with adequate respiratory function. INTERPRETATION: Autologous nasal cartilage tissues can be engineered and clinically used for functional restoration of alar lobules. Engineered cartilage should now be assessed for other challenging facial reconstructions. FUNDING: Foundation of the Department of Surgery, University Hospital Basel; and Krebsliga beider Basel.

Second free radial forearm flap for urethral reconstruction after partial flap necrosis of tube-in-tube phalloplasty with radial forearm flap: a report of two cases.

We present a salvage procedure to reconstruct the neo-urethra after partial flap necrosis occurring in free radial forearm flap (RFF) phalloplasty for sex reassignment surgery. Two cases of tube-in-tube phalloplasty using a free sensate RFF are described in which partial flap necrosis occurred involving the complete length of the neo-urethra and a strip of the outer lining of the neo-phallus. Neo-urethra-reconstruction was performed with a second RFF from the contralateral side providing well-vascularized tissue. No flap-related complications were observed. Twelve months postoperatively, both patients were able to void while standing. A satisfactory aesthetic appearance of the neo-phallus could be preserved with an excellent tactile and erogenous sensitivity. Using this technique, we successfully salvaged the neo-urethra and reconstructed the outer lining of the neo-phallus

Three-dimensional laser surface scanning in rhinosurgery.

Objective outcome analysis of nasal surgery remains difficult. Recently, evaluation of nasal shape following rhinosurgery shifted from two-dimensional evaluation to more sophisticated three-dimensional (3D) analysis techniques, including stereophotogrammetry, computed tomography, and 3D laser scanning. This article explores the feasibility of using 3D laser surface scanners as a tool for preoperative planning and quality control in rhinosurgery.

Facing depression with botulinum toxin: a randomized controlled trial.

Positive effects on mood have been observed in subjects who underwent treatment of glabellar frown lines with botulinum toxin and, in an open case series, depression remitted or improved after such treatment. Using a randomized double-blind placebo-controlled trial design we assessed botulinum toxin injection to the glabellar region as an adjunctive treatment of major depression. Thirty patients were randomly assigned to a verum (onabotulinumtoxinA, n = 15) or placebo (saline, n = 15) group. The primary end point was change in the 17-item version of the Hamilton Depression Rating Scale six weeks after treatment compared to baseline. The verum and the placebo groups did not differ significantly in any of the collected baseline characteristics. Throughout the sixteen-week follow-up period there was a significant improvement in depressive symptoms in the verum group compared to the placebo group as measured by the Hamilton Depression Rating Scale (F((6,168)) = 5.76, p < 0.001, η(2) = 0.17). Six weeks after a single treatment scores of onabotulinumtoxinA recipients were reduced on average by 47.1% and by 9.2% in placebo-treated participants (F((1,28)) = 12.30, p = 0.002, η(2) = 0.31, d = 1.28). The effect size was even larger at the end of the study (d = 1.80). Treatment-dependent clinical improvement was also reflected in the Beck Depression Inventory, and in the Clinical Global Impressions Scale. This study shows that a single treatment of the glabellar region with botulinum toxin may shortly accomplish a strong and sustained alleviation of depression in patients, who did not improve sufficiently on previous medication. It supports the concept, that the facial musculature not only expresses, but also regulates mood states.

Managing the ear as a donor site for composite graft in nasal reconstruction: update on technical refinements and donor site morbidity in 110 cases.

Reconstruction of multilayer defects of the lower nose, using composite grafts from the ear is a widespread technique. Little information exists about important aspects of managing the ear as a donor site for composite grafts. In a retrospective study, patient data were worked up concerning special preoperative planning features (donor site, recipient site), defect closure techniques, donor site morbidity, and esthetic and functional long-term results. One hundred ten composite grafts from the auricle were harvested for different defects at the lower nose. Skin and soft-tissue defect reconstruction at the auricle was carried out by tissue advancement in 43 cases or local flaps in 66 cases. Donor site morbidity was low (5 cases of delayed wound healing, 1 abscess). No flap necrosis occurred. Long-term follow-up (2-5 years) revealed no esthetic or functional impairments. Composite graft harvesting from the auricle is safe with minimal donor site morbidity, proper implementation assumed.
