Abstract
Endoscopic sinus surgery has been the first choice of treatment for postoperative maxillary cysts (POMC). In some cases, however, postoperative obstruction still occurs. Recently, endoscopic modified medial maxillectomy (EMMM) was reported to be an effective surgery for inverted papilloma and POMC. EMMM is a surgical procedure that preserves the lateral wall of the nasal cavity and nasolacrimal duct, while providing better access to the maxillary sinus.
We performed conventional endoscopic sinus surgery for 17 cases (20 sides) with POMC between January 2012 and December 2012. Of these cases, we performed EMMM in 11 cases (11 sides), of which one case suffered recurrence in the follow-up period.
EMMM is an effective procedure for POMC that occurs in the anterosuperior portion, which is very difficult to reach by conventional endoscopic sinus surgery. EMMM expands the indications for endoscopic surgery.
