A Comparative Clinical Study of Flap Thickness: Medial Sural Artery Perforator Flap Versus Anterolateral Thigh Flap

Introduction The purpose of this study is to measure flap thicknesses of anterolateral thigh (ALT) and medial sural artery perforator (MSAP) flaps in healthy subjects by Doppler ultrasonography and compare the results in relation to sex and body mass index (BMI). Method The perforators of ALT and MSAP flaps were marked on 30 healthy subjects. The thickness of skin and subcutaneous tissue was measured in millimeters at the site of the perforator using Doppler ultrasonography. Results The mean ± SD age of the participants was 36.4 ± 10.5, the mean ± SD BMI was 25.2 ± 3.9 (19.4–32.5). The mean ± SD flap thickness was 11.55 ± 4.38 mm for ALT and 8.31 ± 3.6 mm mm for MSAP (P
