초록

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. Korean J Otorhinolaryngol-Head Neck Surg 2016;59(11):780-6
