Abstract
Endoscopic modified medial maxillectomy (EMMM) is a method of directly approaching the maxillary sinus endoscopically. We report on EMMM performed in our department. We performed EMMM in 26 cases. There were 18 men and 8 women, with an average age of 56.5 years. The breakdown of cases was as follows: 9 cases were inverted papilloma, 8 cases were postoperative maxillary cyst, 3 cases were choanal polyp, 2 cases were radicular cyst, 2 cases were impacted teeth, 1 case was hematoma of the maxillary sinus, and 1 case was maxillary sinus mycosis. Of these, there were 3 cases of postoperative recurrence and 3 cases of cheek numbness and pain.
