Abstract: PURPOSE: To explore a flap design technique based on anatomy to achieve precise subtotal tongue reconstruction and evaluate the clinical efficacy. METHODS: Forty-four patients suffering from tongue squamous carcinoma received subtotal tongue reconstruction with anterolateral thigh flap, they were randomly divided into 2 groups according to flap design methods, a "five-points eight-line-segments"(FIPELS) group (23 patients) and a conventional flap design group (21 patients). All patients received nerve coaptation to the lingual or glossopharyngeal nerve. Likert scale was applied to assess the swallowing function, speech articulation, cosmetic outcomes, as well as epicritic sensation, proprioception and thermal sensitivity of the reconstructed tongue. The outcomes were analyzed by SPSS 18.0 software package. RESULTS: All flaps healed well, except 3 patients developed partial necrosis. FIPELS group attained larger area of flap than conventional group. Compared to the conventional group, the swallowing function (P=0.016) and cosmetic outcomes (P=0.001) in FIPELS group were significantly improved, but the speech articulation failed to achieve better outcome (P=0.064). Patients in both groups recovered similarly in epicritic sensation proprioception and thermal sensitivity. CONCLUSIONS: The clinical efficacy of FIPELS design based on anatomy for precise subtotal tongue reconstruction is remarkable and worthy of popularization.
