ABSTRACT
BACKGROUND AND OBJECTIVES: Anterolateral thigh (ALT) flaps are commonly used for head and neck surgery reconstruction. However, a thick ALT often leads to long operation times. Therefore, ALT thickness on a preoperative non contrast image of positron emission tomography-computed tomography (PET-CT) scan was measured to predict surgical outcome. SUBJECTS AND METHOD: The correlation between ALT thickness and total reconstruction time was analyzed in 106 patients. The differences in ALT thickness between the successful and compromised-flap groups were analyzed retrospectively. RESULTS: Median ALT thickness was 4.49 mm, and total reconstruction time was 190 min. Total reconstruction time was significantly correlated with ALT thickness (p=0.019). ALT thickness, body mass index (BMI), total reconstruction time and ischemia time were significantly greater in the compromised-flap group than in the successful group. In the multivariate analysis, only BMI and ischemia time were predictors for the compromised flap. CONCLUSION: ALT thickness measured on a non-contrast image of PET-CT scan is useful as a surgical outcome predictor with respect to total reconstruction time. A further study may suggest the risk of a thick ALT in a compromised flap in head and neck reconstruction using an ALT free flap.
