Sliding anterior hemitongue flap for posterior tongue defect reconstruction.

Posterior tongue defects present a unique reconstructive challenge. The various reconstructive options available for treating the defect created by a posterior hemiglossectomy frequently result in a distorted tongue and functional impairment. This paper describes a novel sliding anterior hemitongue flap to allow reconstruction of moderate resection defects (i.e. for T1-T2 tongue squamous cell carcinomas) of the posterior tongue. By mobilizing the anterior tongue, near normal mobility and tongue length are maintained. This surgical technique may be performed alone intraorally or in combination with a neck dissection.
