[Experimental study of endosurgical approaches to maxillary sinuses].

Studies on 30 cadavers were carried out in order to develop endoscopic approaches to diagnosis and treatment of inflammatory and tumorous diseases of the maxillary sinuses. Morphometric data helped objectively validate surgical accesses and experimentally confirmed the efficiency of three accesses: from the maxillary tuber, through the anterior wall, and through the inferior nasal passage. Endosurgical approaches allow radical operations with minimum injury and ensure functional and esthetic effects.
