Abstract

Approaches to the infratemporal fossa and nasopharynx are difficult because of the anatomic complexity of these regions. We describe our experience with osteoplastic maxillotomy, with our own modifications, and evaluate oncological outcomes and postoperative quality of life. Ten patients underwent osteoplastic maxillotomy, 3 of whom had a diagnosis of malignancy, and 7 of whom had nasopharyngeal angiofibromas (NPAs). A Weber-Fergusson incision was made to develop facial flaps and preserve the vascularity of the maxilla. Osteotomies were performed through the facial aspects of the maxilla, on the orbital rims, and on the malar eminence for the medial variant of the procedure. The anterolateral variant involved descent of the temporalis muscle with preservation of the facial nerve, and a zygomatic osteotomy. Four craniotomies were done. Two patients had the medial variant of the procedure, and 8 had the anterolateral variant. The complications were transient and mild. The patients who had malignancies are alive with no disease, and there was 1 recurrence among the 7 patients with NPAs. We found excellent aesthetic results in 8 of the 10 patients, and no change in basic functions in 8 patients. Osteoplastic maxillotomy allows resection of massive NPAs with no significant bleeding. Resection of malignant lesions with good results is feasible.
