Comparison between anterolateral thigh, radial forearm, and peroneal artery flap donor site thickness in Asian patients-A sonographic study

Purpose This study aimed to determine the thicknesses of the three locations used as donor sites for radial forearm (RF), anterolateral thigh (ALT), and peroneal flaps and to determine probable contributing factors of the thickness. Methods This study included 201 healthy participants (mean age: 45.8 ± 17.2 years; male: 114; female: 87; BMI: 24.3 ± 4.3). Sonography was used to measure the thickness of flap donor sites. Forward stepwise regressions were conducted to determine the contributing factors of flap thickness. Results The RF flap (0.28 ± 0.08 cm) was thinner than peroneal flap (0.47 ± 0.17 cm) (P
