Clinical Outcomes and Applicability of Serratus Anterior Muscle Flap With Split Thickness Skin Graft in Thin Resurfacing Reconstructive Surgeries

초록

This retrospective study evaluates the efficacy of the serratus anterior muscle (SAm) free flap combined with a split thickness skin graft (STSG) for thin resurfacing in reconstructive surgery, presenting an alternative to pure skin perforator flaps. It analyzes 14 SAm free flap procedures performed between January 2015 and December 2023. The study cohort comprised 5 women and 9 men, aged 31-80 years, addressing defects caused by infection, malignancy, burn, and trauma, located in various body parts. The study involves harvesting the SAm flap while focusing on anatomical features such as the distinct direction of muscle fibers and the surface location of the vascular pedicle for efficient dissection. It emphasizes the anatomical advantages of the SAm flap, such as robust vascular supply, controlled flap thickness, and preservation of the long thoracic nerve, making it suitable for a range of surgical needs. Complications included STSG loss, partial necrosis, and infection, all managed effectively. Postoperative shoulder function assessment showed no significant impairment. Results demonstrated the successful application of the SAm flap in all cases, with an average flap dimension of 38.21 cm2 and pedicle length of 7.3 cm. The average operation time was 122.1 minutes. The study underscores the SAm flap's adaptability, versatility, and minimal donor site morbidity. It concludes that the SAm flap, in conjunction with STSG, is a viable alternative for thin resurfacing in reconstructive surgery. However, limitations such as the small sample size and procedural variability suggest the need for further research to fully establish the flap's potential in diverse surgical contexts.
