A modified classification for the maxillectomy defect

Background. At present no widely accepted classification exists for the max illectomy defect suitable for surgeons and prosthodontists. An acceptable c lassification that describes the defect and indicates the likely functional and aesthetic outcome is needed. Methods. The classification is made on the basis of the assessment of 45 co nsecutive maxillectomy patients derived prospectively from the database (Se ptember 1992) and retrospectively from 1989. Results. The classification of the vertical component is as follows: Class 1, maxillectomy without an ore-antral fistula; Class 2, low maxillectomy (n ot including orbital floor or contents); Class 3, high maxillectomy (involv ing orbital contents); and Class 4, radical maxillectomy (includes orbital exenteration); Classes 2 to 4 are qualified by adding the letter a, b, or c . The horizontal or palatal component is classified as follows: a, unilater al alveolar maxillectomy; b, bilateral alveolar maxillectomy; and c, total alveolar maxillary resection. Conclusion. This practical classification attempts to relate the likely aes thetic and functional outcomes of a maxillectomy to the method of rehabilit ation. (C) 2000 John Wiley & Sons. Inc.
