Application of an L-shaped anterolateral thigh flap in reconstruction after hemiglossectomy

OBJECTIVE: Tongue defect reconstruction is one of the key components of tongue cancer surgery. In this study, we used an L-shaped flap design adopted as a simple and efficient method to repair tongue defects after hemiglossectomy. Furthermore, we evaluated and contrasted the clinical effects of two methods, the L-shaped and traditional methods. STUDY DESIGN: Fifteen patients in the L-shaped group and 20 patients in the traditional group were evaluated and compared in terms of postoperative complications, dysphagia, language function and appearance satisfaction. RESULTS: The results (Table 1) showed that there were 2 cases of donor area invalid traumas, and 2 patients had scar hyperplasia in the traditional group. The degree of global and functional dysphagia of the L-shaped group (2.60 ± 0.29 and 11.47 ± 1.38) was lower than that of the traditional group (3.55 ± 0.29 and 15.75 ± 1.22) (P < 0.05). In the language evaluation, the traditional group (3.20 ± 0.26) had lower scores than the L-shaped group (4.13 ± 0.30) (P < 0.05). CONCLUSION: The L-shaped ALTP flap is a simple and efficient modification of ALTP, that can be used for half-tongue repair after radical operations for tongue cancer. It has better performance in the recovery of dysphagia and language function than the traditional ALTP flap.
