Abstract
BACKGROUND: The treatment of soft tissue defects with exposed cartilage after tumor excision is challenging. Local flap reconstruction causes occasional scarring, especially in non-Caucasian populations. Scar treatment requires secondary procedures for aesthetic modifications. Two-step reconstruction with an acellular dermal matrix addresses this issue and yields highly acceptable aesthetic resultsWe aimed to investigate the efficacy of an artificial dermal matrix cover using one-step reconstruction for defects with cartilage exposure. METHODS: From July 2018 to September 2020, seven patients were enrolled and underwent a single-stage operation using acellular dermal matrices. Patients were followed up for at least 6 months and the size of the wound, days to heal, patient satisfaction, and scar scale scores were recorded. RESULTS: Patients were followed up for an average of 25.7 months. The average time to heal was 23.4 days postoperatively. No hyperpigmentation, tumor recurrence, or retraction was noted. High acceptance and satisfaction with the outcome were observed in all patients. CONCLUSIONS: Single-stage reconstruction yielded high acceptance of aesthetic results similar to that in two-stage reconstruction. Less time and cost make this an effective and efficient treatment for soft tissue defects compared with traditional techniques.
