A Case of Primary Septated Mucocele of Maxillary Sinus / 대한이비인후과학회지

ABSTRACT

Paranasal sinus mucoceles are benign non-neoplastic condition characterized by cystic expansion. They are classified into primary and secondary mucoceles by known causes. Most mucoceles are located in the frontal and anterior ethmoid sinuses and they involve the frontoethmoial region, expanding to the region of the orbit, leading to the ocular symptoms. The primary maxillary sinus mucoceles are not common, whereas secondary ones such as postoperative maxillary sinus mucoceles (POMMs) developing after Caldwell-Luc operation are pretty common. POMMs have often multiple septated mucoceles. However, most of the primary maxillary sinus mucoceles are an expansile and cystic mass of maxillary sinus with medial bulging. We present a case of primary septated mucocele in the maxillary sinus of a 36-year-old male who underwent revision surgery.
