Abstract

Objective of this paper aims to evaluate the result of thinning the anterolateral thigh flap in plastic surgery. The study was carried out on 24 patients who underwent ALT flap thinning at the Department of Plastic surgery of Saint Paul Hospital and Bach Mai Hospital between January 2017 to August 2021. Primary thinning was performed on 23 out of 28 flaps (82.14%) to remove the deep adipose tissue with Mayo scissors and microdissected thinning by microscopy was performed on the remaining 5 flaps (17.86%) to remove an extra part of superficial adipose tissue. ALT thinning flap was harvested with 1.5x1.5cm of minimal deep fascial spared. Complete flap survival in  26 out of 28 flaps (92.86%), partial flap necrosis in the remaining 2 flaps (7.14%); average flap thinning area was 139.11±67.95cm2, the largest flap was 322cm2, the average flap thickness after thinning was 0.49±0.12cm, the thinnest flap obtained was 0.3cm. The short term result showed flaps with good coverage and good healing. Moreover, patients were satisfied with aesthetic and functional results in long-term follow-ups. In conclusion, the primary or microdissection ALT flap can be used multi-purposely, safely, and effectively in plastic surgery to cover defects in various areas that need thinned flaps to improve functional and aesthetic results.
