SURGICAL TREATMENT OF MAXILLARY MALIGNANT TUMORS

Surgical treatment is the choice of treatment for the maxillary malignant tumors. Conventional maxillectomy technique dosen t allow the easy approach to the pterygomaxillary plate area and leads to the troublesome problems such as the ptosis of oribital content. Through some technical modifications of the maxillectomy as preservation of the infraorbital rim and use of zygomaticomasseter and coronoidotemporalis flaps, we obtained good results as follows; prevention of the ptosis of the oribital content, easy exposure of the pterygoid plate, reduction of the interoperative bleeding and easy ligation of the internal maxillary artery under direct vision.
