Scalp reconstruction with locoregional and free flaps - a retrospective cohort study.

Abstract

Scalp defect reconstruction requires interdisciplinary cooperation to restore soft tissue and osseous defects. While wound closure and form restoration, often a short-term treatment goal, ensures patient survival, the long-term preservation of the head and neck's integrity and aesthetics is crucial for maintaining quality of life. This study aims to compare, quantify, and establish a safe and reproducible approach to various reconstruction options and the postoperative complication profile for individual scalp defect areas. We retrospectively evaluated patients who underwent scalp reconstruction at our institution between March 2017 and April 2022. The inclusion criterion was the presence of a soft tissue defect at the cranium level. We included 31 patients in the study (17 males, 14 females), with an average age of 61 years (range 17-92 years). Eight patients had received radiotherapy in the affected region. The mean defect size was 72.5±116 cm2 (range 20-441 cm2), and an average of 3±2 surgeries had been performed before the plastic surgical treatment was initiated. Eleven patients had only a soft tissue defect, while 20 patients had an associated bone defect. Fifteen of these patients received a cranioplasty. The rotation flap was the most frequently used (n=23), with or without split-thickness skin grafting, followed by the free latissimus dorsi muscle flap with split-thickness skin grafting (n=5), and the free lateral arm flap (n=2). Revision surgeries were necessary in 38.7% of cases due to wound healing disorders (n=9), bleeding (n=2), and cerebrospinal fluid leaks (n=1). Eventually, all wounds were successfully closed. Complex scalp defects can be closed using local flaps, thereby restoring aesthetics and tissue integrity. Free flaps remain a reliable solution for extensive defects. Moreover, in cases requiring cranioplasty, careful preoperative planning and an uncontaminated wound are essential for successful treatment.
