Abstract

OBJECTIVE
This article describes use of the osteoplastic technique in the treatment of maxillary benign tumors. This procedure yielded favorable outcomes in situations where the tumor was difficult to remove using the standard endoscopic approach.
METHODS
This study included six sinuses of six patients with maxillary sinus benign tumors (five inverted papillomas and one hemangioma). The tumors were located in the anterior wall of the maxillary sinus and were difficult to remove by the endoscopic approach. The traditional gingivobuccal incision was performed to expose the anterior maxillary sinus wall. A rectangular bone flap was designed on the anterior maxillary wall and a bony window was made using a reciprocating saw. After eradicating all lesions, the bone flap was repositioned to its original site and fixed with a miniplate. Postoperative paranasal sinus computed tomography was performed after 12 and 24 months.
RESULTS
All bone flaps healed without any complications. Patients had succes-sful postoperative outcomes without any complications. In one inverted papilloma case, the lesion recurred and was removed easily with the same procedure.
CONCLUSION
The osteoplastic technique is a simple and useful method to eradicate benign lesions in the maxillary sinus due to its good access to the maxillary sinus antrum, optical surgical view, and minimal complications.
