Upper Blepharoplasty Under Anticoagulant or Antiplatelet Therapy: Is Safety Still a Concern?
Objective: Dermatochalasis is defined as a skin excess in the upper or lower eyelid which may be associated with orbital fat prolapse, lacrimal gland prolapse, and involutional blepharoptosis. Upper blepharoplasty is the gold-standard procedure for correcting dermatochalasis and is the third most common cosmetic surgery performed in the United States. However, it is frequently performed on elderly patients, who are often ongoing anticoagulant and/or antiplatelet therapy. Due to the associated elevated risk of bleeding, it remains unclear whether upper blepharoplasty can be safely performed in this patient population. This study aimed to investigate the safety of upper blepharoplasty in patients receiving antithrombotic therapy. Material and Methods: A retrospective comparative study was conducted on 392 consecutive patients who underwent upper blepharoplasty for dermatochalasis at a single academic center over a three-year period. Patients with a history of prior eyelid or orbital surgery were excluded. The cohort was stratified into two groups: a study group of 100 patients on anticoagulant/antiplatelet therapy (including aspirin, warfarin, and apixaban) and a control group of 292 patients not on such therapy. Postoperative complications, clinical outcomes, and satisfaction scores (from both patients and surgeons) were compared between the groups. Results: Baseline characteristics differed significantly between groups, with patients on anticoagulant/antiplatelet therapy being older and having higher comorbidity rates. Operative time, estimated blood loss, time to return to work, and follow-up duration were comparable. The overall complication rate was not significantly different between the antithrombotic and control groups (6.0% vs. 3.5%, p =0.380). Notably, no major bleeding events occurred. The incidence of ecchymosis requiring extended observation was low and not significantly different (1.0% vs. 0.0%, p =0.573). Patient-reported and surgeon-assessed satisfaction scores were high and similar between groups. Reoperation rates were also equivalent. On multivariable logistic regression analysis, no variable was identified as a significant independent predictor of complications; however, hypertension demonstrated the highest odds ratio (OR 2.9, 95% CI 0.29-28.56, p =0.370). Conclusions: Upper blepharoplasty appears to be safely performed in carefully selected patients receiving anticoagulant or antiplatelet therapy. In this retrospective cohort, continuation of antithrombotic therapy was not associated with an increased rate of detected complications compared with controls. These findings support the feasibility of maintaining therapy in appropriately selected cases, although larger prospective studies are required to confirm these observations.

Upper Blepharoplasty for Dermatochalasis With or Without Resection of the Orbicularis Oculi Muscle, Preaponeurotic and Nasal Fat Pads: A Comparative Study
Objective: Upper blepharoplasty is the gold standard procedure for upper eyelid dermatochalasis. Upper blepharoplasties procedures include removing the skin, orbicularis oculi muscle, preaponeurotic, or nasal fat pad. The purpose of this study is to report surgical outcomes and compare them to the most common techniques. Material and Methods: A retrospective review of 386 consecutive patients who underwent upper blepharoplasty at Turku University Hospital from January 1st, 2015 to June 30th, 2017 was conducted. Data collected include patient demographics, surgical details, and details regarding the type and frequency of complications. Results: During the study period, 51 upper blepharoplasties with orbicularis oculi muscle excision, skin, preaponeurotic and nasal fat pads removal (study group) and 335 upper blepharoplasties with skin only removal (control group) were performed. Non-parametric tests showed that operative time (M=60.2min; SD=11.7min) and return to work (M=8.0days; SD=3.1days) were significantly shorter in the control group. No significant differences in the total amount of complications were detected (7.8% vs 2.4%, p=0.075). Subjective patients' satisfaction was significantly higher in the study group (from 0-10, mean 8.3 vs 7.0, p=0.034). Conclusions: When compared to skin-only blepharoplasty, upper blepharoplasty with orbicularis oculi muscle excision, removal of skin, preaponeurotic and nasal fat pad appears to be a safe surgery with improved patient satisfaction and without carrying on additional complications.

Melanoma of the Scalp and Neck: A Population-Based Analysis of Survival and Treatment Patterns
Introduction: Melanoma is an aggressive skin cancer. Large demographic and clinic-pathologic studies are required to identify variations of tumour behavior. The aim of our study was to offer updated epidemiologic data on the scalp and neck melanoma with an overall survival analysis. Method: The SEER database was searched for all scalp and neck melanoma in adult patients between 2000 and 2019. Demographic and clinic-pathologic variables were described. Their impact on overall survival was assessed with the log-rank test after Kaplan–Meier model. A multivariable cox-regression was conducted to identify predictors of decreased survival. A p-value of <0.005 was considered statistically significant. Results: 20,728 Melanomas of the scalp and neck were identified. Mean age was 62.5 years. Gender ratio was 76.3% males. 79% of the tumours were localized at diagnosis. Increasing age, male gender, tumour ulceration, high mitotic rate or nodular subtype were independent prognostic factors of decreased overall survival. Surgery with less than 1 cm margin is associated with the best overall survival in this cohort. No significant difference in OS was seen between less than 1 cm and 1 to 2 cm margins. Conclusion: Knowledge of negative prognostic factors might help identify subgroups at risk and adapt their oncologic treatment.

Surgical Outcomes of VRAM vs. Gracilis Flaps in Vulvo-Perineal Reconstruction Following Oncologic Resection: A Proportional Meta-Analysis
Pelvic exenteration and abdominoperineal resection are radical techniques commonly used for locally advanced or recurrent pelvic malignancy with high morbidity due to large pelvic defects. Flaps can help provide healthy, well-vascularized, non-irradiated tissues to fill pelvic dead space. We conducted a proportional meta-analysis to compare surgical outcomes of vertical rectus abdominus myocutaneous flap (VRAM) vs. gracilis flap for vulvo-perineal reconstruction following oncologic resection. A comprehensive literature search was conducted in the MEDLINE, PubMed, Embase, Google Scholar, and Cochrane Library databases. Proportional meta-analysis was performed to compare the surgical outcomes of using VRAM or gracilis flaps. Our review yielded 16 eligible studies. The pooled resolution rate of overall donor site complications for VRAM flap (pooled proportion = 0.576 [95% CI 0.387, 0.754]) was significantly higher than the pooled rate of overall donor site complications of gracilis flap (pooled proportion = 0.160 [95% CI 0.058, 0.295]). Partial and total flap necrosis were similar in both groups. There was no statistically significant difference between minor and major complications for both flaps. Both flaps can be used safely for vulvo-perineal reconstruction following oncologic resection with similar recipient site outcomes, although the VRAM flap will have more donor site complications than the gracilis flap.

Reduction Mammoplasty: A Ten-Year Retrospective Review of the Omega Resection Pattern Technique
Reduction mammoplasty is the gold standard procedure for symptomatic breast hypertrophy and it is also used for contralateral breast symmetrisation following breast cancer surgery. We aim at introducing a new procedure, which uses an omega resection pattern to simplify the inferior pedicle breast resection technique. A retrospective review of all patients who underwent the omega resection reduction mammoplasty at the University Hospital of Basel between 2010 and 2020 was carried out. We collected patient demographics, surgical outcomes, operation time, type and frequency of complications at 12 months follow-up. Outcomes were compared with the most commonly used techniques. Additionally, we assessed if patients’ and clinical characteristics augmented/diminished the complication rate. During the study period, 67 reduction mammaplasties were performed by a senior plastic surgeon (Mage = 42.5, SDage = 15.6; MBMI = 27.28, SDBMI = 3.4; 20% smokers). The average tissue removed was 826 g (ranging from 15 to 2307 g). In 10 breasts (15%) occurred minor complications. No major complications were reported. Operation time (M = 149 min; ranging from 87 to 270 min) was significantly shorter than the inferior, superomedial, and superior pedicle techniques. Univariate Odd Ratios showed that no-smoker status, a BMI in a normal range, resection weight between 500 g to 1500 g, NTN distance < 30 cm, removal of drains one day after the operation, ASA index of 2, inpatient clinic hospitalisation, and not undergoing other concomitant surgical operations were protective factors against the risk to develop complications. The omega resection pattern technique demonstrated to be an effective, safe, and fast mammoplasty reduction procedure for bilateral macromastia and unilateral symmetrizing procedures, even for large breasts, able to be adopted as a new valid alternative to the existing ones.
