Biomechanical and biological advantages of retaining the silicone-induced capsule for cartilage graft survival in revision rhinoplasty.

To answer the increased demand for augmentation rhinoplasty, particularly in Asian demographics, a shift from autogenous materials to synthetic implants like silicone and expanded polytetrafluoroethylene has been witnessed. These materials present an increased risk of complications like infection, extrusion, capsular contracture, and dissatisfaction. This study focuses on a case of revision rhinoplasty in a 48-year-old patient with a previous silicone implant and propose an innovative approach in managing the implant capsule. The use of the existing capsule as a mechanical and biological support structure for the diced cartilage graft in dorsal reconstruction showcases a promising method to mitigate risks and improve outcomes in revision surgeries. The capsule around the silicone is biologically active and provides a good environment for the cartilage graft to survive and improve the healing process. This approach tends to minimize the dissection to avoid potential revision complications like skin necrosis, fibrotic tissue, and infections.

The Surgical Treatment of Tuberous Breast Deformity: A Review Article.

ABSTRACT: Tuberous breast is a common congenital deformity that might present as unilateral or bilateral breast base constriction, asymmetry, areolar herniation, hypoplasia, ptosis, and skin deficiency. Patients might present with one or more of the mentioned features, rendering a consensus about the optimal surgical technique to correct this deformity nonexistent. In our review article, we present the most common classifications of a tuberous breast, in addition to several surgical approaches that attempt to treat this deformity.

Depressor Reanimation After Facial Nerve Paralysis.

Facial expressions play a fundamental role in interpersonal communication and interaction; consequently, facial palsy has profound effects on the quality of life of patients. Reanimation of lower lip depressors is rarely addressed during facial reanimation but is as important as treating the eye sphincter and the lip levators. Depressors of lower lip are vital for full denture smile and the expression of facial emotions. Static and dynamic techniques are used to reanimate the lower lip depressors. Static techniques provide stationary results either by weakening the contralateral normal side to achieve symmetry using botulinum toxin injection, depressor labi inferioris myectomy and marginal mandibular nerve neurectomy, or by creating static slings and tightening procedures on the affected side. Dynamic techniques provide functional results by reanimating the affected depressor complex using nerve transfers, muscle transfers, and direct muscle neurotization. The purpose of this article is to present an overview of the literature on the applications of these techniques in lower lip reanimation. Furthermore, preoperative evaluation and indications are also discussed.

Skin adverse events in recently approved targeted therapies in solid malignancies.

Targeted anticancer therapies are an important weapon in the fight against cancer. Targeted therapies interfere with specific molecules necessary for tumor growth and cancer progression. They are divided mainly to either monoclonal antibodies or small molecules inhibitors. Their primary objective is to target directly and precisely the cancer cells leading to a minimal side-effects profile. The dermatologic adverse reactions of these targeted therapies is different from those seen with classical cytotoxic chemotherapy. Rashes, xerosis, hand-foot-skin reaction and mucositis are the most frequent side effects. In this paper, we aim to present a comprehensive review of the dermatologic side effects of targeted therapies including, specific side effects related to recently, approved targeted therapies.

End-to-Side Nerve Repair: Current Concepts and Future Perspectives.

Peripheral nerves injuries are extremely debilitating and have been a perennial challenge to the reconstructive surgeon. End-to-side (ETS) neurorrhaphy is a potential strategy for treating nerve lesions without usable proximal nerve stump. A number of interesting clinical and experimental studies have been carried out on ETS nerve repair during the first years of the 20th century. End-to-side nerve repair was then almost abandoned for more than 50 years. The rediscovery of ETS nerve repair was attributed to the experimental work of Viterbo.Two mechanisms have been suggested for axonal regeneration: terminal and collateral sprouting. While in collateral sprouting axonal outgrowth occurs along the length of the uninjured axons, in terminal sprouting, axonal regeneration takes place at the distal most aspect of either injured or uninjured axons. Clinical experience with ETS nerve repair includes management of upper extremity nerve injury, facial reanimation, reconstruction after tumor ablation, and the prevention of neuroma formation.The aim of this review article was 2-fold: (1) overviewing the most interesting experimental investigations and clinical studies published so far; (2) calling for more basic research on ETS nerve repair indicating the several unanswered questions that this concept asks to the microsurgical community.

Painful Neuroma Treatment of the Supraorbital Nerve and Forehead Neurotization Using Human Cadaveric Nerve Allograft.

Neuroma pain can be severe, persistent, and treatment-resistant. Forehead and scalp anesthesia is troublesome for patients. Following an iatrogenic ablative injury to the right supraorbital nerve, with subsequent painful neuroma formation, a human cadaveric nerve allograft (AxoGen, Alachua, FL) was used to restore sensation of the right forehead and treat pain. At 1-year follow-up, the patient was pain-free, and protective sensation to the right forehead was recovered with comparable static and dynamic 2-point discrimination between the injured (20 mm, 12 mm respectively) and the normal side (15 mm, 10 mm respectively). This is the first reported case of using a cadaver nerve allograft for successful direct neurotization of the skin and restoration of sensation in the upper part of the face, and for treating painful neuromas. Moreover, a brief review of the available techniques for treating neuromas of the supraorbital and supratrochlear nerves is provided.

The Surgical Management of Nerve Gaps: Present and Future.

Peripheral nerve injuries can result in significant morbidity, including motor and/or sensory loss, which can affect significantly the life of the patient. Nowadays, the gold standard for the treatment of nerve section is end-to-end neurorrhaphy. Unfortunately, in some cases, there is segmental loss of the nerve trunk. Nerve mobilization allows primary repair of the sectioned nerve by end-to-end neurorrhaphy if the gap is less than 1 cm. When the nerve gap exceeds 1 cm, autologous nerve grafting is the gold standard of treatment. To overcome the limited availability and the donor site morbidity, other techniques have been used: vascularized nerve grafts, cellular and acellular allografts, nerve conduits, nerve transfers, and end-to-side neurorrhaphy. The purpose of this review is to present an overview of the literature on the applications of these techniques in peripheral nerve repair. Furthermore, preoperative evaluation, timing of repair, and future perspectives are also discussed.

Gluteal Implants Versus Autologous Flaps in Patients with Postbariatric Surgery Weight Loss: A Prospective Comparative Study of 3-Dimensional Gluteal Projection After Lower Body Lift.

BACKGROUND: Deformities and excess skin resulting from massive weight loss are corrected with circumferential lower body lift (LBL). The gluteal area is frequently flattened due to aggressive skin excision during LBL. Gluteal implants can circumvent this problem. OBJECTIVES: We aimed to objectively evaluate the outcomes of gluteal augmentation with implants versus flap surgery performed simultaneously with LBL. METHODS: Between January 2014 and June 2015, twenty-seven patients underwent LBL with gluteal implants (10 patients), flaps (14 patients), or no gluteal augmentation (3 patients) in our hospital. Three-dimensional analysis was used to assess gluteal projection preoperatively and at 6 months. Gain in projection, pain scores, complications, and patient and surgeon satisfaction were compared. RESULTS: The mean follow-up duration was 18 months. The mean gain in projection at 6 months was 4.9 mm in the implant group, -0.5 mm in the flap group (P = 0.1), and -9.6 mm in the control group. The mean implant volume was 294.5 mL. Operation time was shorter in the flap group (192 min) than in the implant group (218 min, P = 0.001). Surgeon satisfaction was higher in the implant group (P = 0.007). Implants were more painful than flaps at 4 days and 2 weeks (P = 0.004 for both). There were 6 minor complications (60%) in the implant group versus 7 (50%) in the flap group (P = 0.94). CONCLUSIONS: In selected patients, LBL with gluteal implants is safe and slightly increases gluteal projection. LEVEL OF EVIDENCE: 2.

Does the Addition of Progressive Tension Sutures to Drains Reduce Seroma Incidence After Abdominoplasty? A Systematic Review and Meta-Analysis.

BACKGROUND: Progressive tension sutures (PTS) are commonly utilized to reduce postoperative seroma in abdominoplasty. However, current evidence regarding PTS in abdominoplasty is limited to small series and the findings of single institutions. OBJECTIVES: The authors reviewed the available literature concerning the effects of PTS and drains on seroma formation following abdominoplasty, and summarized the different techniques that have been described to date. METHODS: We conducted a systematic review of the Medline, Embase, and Cochrane databases. We identified randomized controlled trials (RCTs) and observational studies in which the numbers of patients who had postoperative seroma were indicated. We applied the Cochrane Collaboration's tool for assessing the risk of bias. RESULTS: Seven studies were included (three RCTs and four retrospective studies). Patients who had PTS and drains following abdominoplasty had a significantly lower rate of postoperative seroma than those who had drains only. The mean surgical time difference between the two groups was 23 minutes. There was no difference in postoperative seroma rate in patients who had PTS and drains placed following abdominoplasty compared to those who had PTS only. CONCLUSIONS: Addition of PTS to drains reduces the risk of postoperative seroma in standard abdominoplasty. More RCTs with larger sample sizes and better comparability are warranted to confirm with more confidence the impact of PTS in abdominoplasty.

Dermatologic adverse events of checkpoint inhibitors: what an oncologist should know.

Immune checkpoint inhibitors (ICI) represent a new revolutionary weapon in the armamentarium of anti-cancer therapies. The side effects of these new agents represent a new challenge for oncologists; they are usually unpredictable and sometimes life threatening, if not managed rapidly and adequately. The most frequent side effects are the dermatologic, but they are usually low grade side effects and consequently easily manageable. Rash, pruritus and vitiligo are the most frequent dermatologic side effects. We aimed in this review to describe first all the dermatologic side effects of ICI according to the subtype of ICI and combination therapies in the clinical trials, then to report all the rare case reports dermatologic side effects, and finally to present the management algorithm of these side effects.
