Defects caused by tumour excision in the floor of the mouth can be closed by different methods. We present thirteen cases treated in our department over the last seven years in whom naso-labial flaps were used. Twelve patients had squamous cell carcinoma of the floor of the mouth and one had fibro-sarcoma of the right lower mandible. Five received post-operative radiotherapy, one was resected following radiotherapy and seven were treated with surgery alone. Patient selection is important to give good functional results without compromising tumour clearance.
