[The reconstruction of the losses of substance in the floor of the mouth with split lingual flaps].

The loses of substance, as a result of malignant tumor removement of floor of the mouth, with or without metastasis in the afferent ganglions, have such multiple and difficult morphological complications, that need immediate and complete reconstruction. From the multiple sources with reconstructive potential of the loco-regional or distant prevention suggested in literature, authors have used lingual musculo-mucosal flap. The use of the lingual flap avoided the inconveniences and the risks of tissue transfer from another origin, offering the advantages of one and only surgery and at the same time the superior morphological and functional results.
