In 6 cases of tumors, two gigantic benign and four malignant in T4 having palatal and gingivo-alveolar starting point with invasive evolution into the structure of facial mass, surpassing the median alignment, the authors consider the problem concerning the indications for exeresis, possibilities of removal of healthy tissue and the reconstruction of massive losses of substance. The surgical treatment of reconstruction that completes the exeresis of the tumor is meant to sustain the ocular globe through a aponeurotic-muscular flap form the temporal muscle, with the aid of nasal septum or a skin graft also used to obtain a good coating of the cavity, and is also meant to a plastic reconstruction of the soft palate as well as to retention modelling of the cavity fields which resulted postsurgically. The main role in maxillofacial reconstruction in held by the obturator prosthesis that avoids morphofunctional prejudices and restores facial contour, without aesthetic and psychic prejudices. The results obtained in our 6 cases shown here have been fully satisfactory.
