Cadaveric Study for Safe Elevation of a Profunda Artery Perforator Flap: Anatomy of the Perforators and Obturator NervesAffiliations
AbstractBackground: This cadaveric study aimed to describe the anatomy of the profunda artery perforators (PAPs). Methods: In total, nine free cadavers with 18 upper thighs were dissected, 12 of which were from female cadavers, and 6 were from male cadavers. The average age of the cadavers was 84.7 ± 4.2 years. Dissection was performed to evaluate the anatomic position and characteristics of the femoral PAPs. The perforator distance from the gluteal sulcus, number of perforators, perforating muscles, diameter of the perforators, origin of the perforators, and number of nerves passing above and below the perforators were determined. Results: The average number of perforators that penetrate the adductor magnus muscle was 2.5. The average distance from the origin of the perforators to the gluteal sulcus was 71.72 ± 28.23 mm. The average numbers of the obturator nerves passing above and below the perforator in the adductor magnus muscle were 1.3 (range, 0-4) and 0.7 (range, 0-2), respectively. Conclusion: The results provide a detailed anatomic basis for the PAP flap. The perforators of a PAP flap may be included in a flap with a transverse design. Sacrificing the small obturator nerves during dissection may not lead to significant donor site morbidity.
Human-Mimic Submuscular and Premuscular Irradiated Rat Model: Histologic Characteristics of the Capsule Tissue in Contact with the Breast ImplantAffiliations
AbstractBackground: In this study, we established two rat models that mimic human submuscular and premuscular breast reconstruction. We analyzed the capsule formation according to surgical techniques and adjacent tissues, including the chest wall tissues, such as the ribs and acellular dermal matrices (ADMs) that come in contact with silicone implants. Methods: This study consisted of experiments on 12 Sprague-Dawley rats that underwent implant reconstruction using ADM. They were divided into two groups: rats that underwent dual-plane implantation (n = 6; group 1) and those that underwent premuscular implant insertion (n = 6; group 2). All rats were irradiated with 35 Gy of fractionated radiation. Three months after surgery, the histology and immunochemistry of the capsule tissues of the ADM, muscle, and chest wall were analyzed. Results: Overall capsule thickness was thicker in group 1. Based on the tissue in contact with the silicone implant, ADM had a thinner capsule, less inflammation, less fibrosis, and less vascularization than the muscle and chest wall tissues. Conclusions: This study described two rat models of clinically relevant implant-based breast reconstruction using a submuscular and premuscular plane, ADM, and irradiation. Overall, the premuscular implantation rat model was associated with a thinner capsule. The ADM in contact with the silicone implant, even after irradiation, had superior protection from radiation compared with the other tissues.
A comprehensive evaluation of ChatGPT consultation quality for augmentation mammoplasty: A comparative analysis between plastic surgeons and laypersonsAffiliations
AbstractObjectives: ChatGPT has gained significant popularity as a source of healthcare information among the general population. Evaluating the quality of chatbot responses is crucial, requiring comprehensive and qualitative analysis. This study aims to assess the answers provided by ChatGPT during hypothetical breast augmentation consultations across various categories and depths. The evaluation involves the utilization of validated tools and a comparison of scores between plastic surgeons and laypersons. Methods: A panel consisting of five plastic surgeons and five laypersons evaluated ChatGPT's responses to 25 questions spanning consultation, procedure, recovery, and sentiment categories. The DISCERN and PEMAT tools were employed to assess the responses, while emotional context was examined through ten specific questions. Additionally, readability was measured using the Flesch Reading Ease score. Qualitative analysis was performed to identify the overall strengths and weaknesses. Results: Plastic surgeons generally scored lower than laypersons across most domains. Scores for each evaluation domain varied by category, with the consultation category demonstrating lower scores in terms of DISCERN reliability, information quality, and DISCERN score. Plastic surgeons assigned significantly lower overall quality ratings to the procedure category compared to other question categories. They also gave lower emotion scores in the procedure category compared to laypersons. The depth of the questions did not impact the scoring. Conclusions: Existing health information evaluation tools may not be entirely suitable for comprehensively evaluating the quality of individual responses generated by ChatGPT. Consequently, the development and implementation of appropriate evaluation tools to assess the appropriateness and quality of AI consultations are necessary. Keywords: Artificial intelligence; Consumer health information; Health literacy; Internet.
