Objective: To investigate the method and efficacy of reconstruction of anterior mouth floor defects with depressor labii inferioris flap.
Methods: Between March 2010 and August 2011, 4 patients with cancer in the anterior part of oral floor underwent tumour resection and simultaneous reconstruction with depressor labii inferioris flap. The patients were followed up for 2 - 18 months. The survival of the flaps, mobility of tongue and esthetic outcome of lip and mental region were evaluated.
Results: All the flaps survived completely, tongues moved well, and functional and esthetic results were good.
Conclusions: The depressor labii inferioris flaps are suitable for repairing defects of anterior oral floor.
