Article Abstract
Background: While autologous breast reconstruction using the profunda femoris artery perforator (PAP) flap is becoming increasingly popular, no aesthetic evaluation has been reported. The aim of this study is to evaluate the reconstructed breast using the PAP flap quantitatively and to clarify which factors contribute to the aesthetically favorable results.
Methods: We identified 127 patients who underwent breast reconstructions using the vertically designed PAP flap for unilateral breast cancer between April 2018 and December 2021. The PAP flap was elevated vertically to avoid disrupting lymphatic pathways and was inserted between the pectoralis major muscle and the subcutaneous fat after the anastomoses. We classified cases into two groups: the "Favorable cosmesis group" and the "Unfavorable cosmesis group" based on aesthetic evaluations using the vectra three-dimensional (3D) imaging system. Patient characteristics and outcomes between two groups were compared.
Results: Of the 127 patients, 15 were excluded: three with stacked PAP flaps, two with flap necrosis, and 10 with missing aesthetic outcome data. Among the remaining 112 patients, 18 were classified in the "Favorable cosmesis group" and 94 in the "Unfavorable cosmesis group." Comparative analysis revealed that the "Favorable cosmesis group" showed significantly higher ratio with small volume in the upper pole of the unaffected side (21% vs. 72%, p < 0.01) and had a smaller final inset flap weight (147 vs. 190 g, p = 0.028) compared to the "Unfavorable cosmesis group." All 112 patients were evaluated using vectra 3D system at 12 months postoperatively, and their postoperative flap courses were uneventful.
Conclusions: In our study, inherent small volume of the upper pole and smaller flap inset weight contribute to more favorable outcomes.

Background: To compare surgical and long-term patient-reported outcomes (PRO) between excisional (Nesbit) and incisional (Yachia) corporoplasty for correction of uncomplicated Peyronie's-related penile curvature in a large, single-surgeon cohort. A retrospective audit identified men who underwent Nesbit or Yachia corporoplasty (2015-2021). Operative data was extracted from records.

Background: Minimally invasive cardiac surgery (MICS) has become a popular approach due to its potential benefits such as improved cosmesis, faster recovery, shorter hospital stays, and cost effectiveness compared to traditional median sternotomy. However, there have been some concerns regarding procedural efficiency and surgical outcomes especially in the early phase of the learning curve of these procedures.
Methods: In March 2025, a systematic review was conducted using MEDLINE, Embase, the Cochrane Library and Google Scholar databases to identify potential studies that quantitively assessed the learning curve in MICS using pre-defined metrics based on surgical times and/or clinical outcomes.
Cosmetic outcomes of rotation flap and suture scaffold for breast-conserving therapy in the lower quadrants.

Background: Achieving good cosmetic outcomes after breast-conserving therapy (BCT) is crucial, particularly for tumors in the lower quadrant (BD region). This study evaluated the cosmetic outcomes of two oncoplastic techniques in patients with breast cancer in the BD region: rotation flap (RF) and suture scaffold (SS).
Methods: This retrospective cohort study, conducted at a single institution, initially identified 45 consecutive female patients with primary unilateral breast cancer who underwent breast-conserving therapy using the RF (n = 22) or SS (n = 23) methods.
Surgical Outcomes of U-Shaped Incisions Versus Conventional Incisions in Parotidectomy.

ImportanceModified Blair and Facelift incisions are conventional approaches to parotid pathologies. However, they frequently result in prominent scars in cosmetically sensitive regions. A newer alternative, U-shaped incision offers a minimally visible scar along the contour of the pinna while enabling management of parotid pathologies.

Objective: To assess the psychological status and quality of life improvements in parents of children undergoing facial trauma repair emphasizing cosmetic outcomes with fast-absorbing collagen sutures, and to compare these outcomes with those in parents of children repaired with nylon sutures. A secondary objective was to compare scar outcomes between the two suture materials.
Methods: From January 2024 to October 2024, 120 primary caregivers (defined as the parent providing ≥80% of daily wound care) of pediatric facial trauma patients were randomized into an observation group ( = 60, 7-0 fast-absorbing collagen sutures, non-removal) or a control group ( = 60, 7-0 nylon sutures, removed on day 7).
