Postoperative maxillary cyst(POMC) or surgical ciliated cyst is defined as a variant of sinus mucoceles which developed after trauma or surgery to the maxillary since. The POMC most frequently originates after a Caldwell-Luc operation or infrequently arises from difficulf extraction of a maxillary tooth. Although the clinicopathologic parameters of POMC involoing Japanese have been studied well, its clinicopathologic parameters in Korean has not been investigated yet. The objective of this investigation is to provide the Korean dentists who have frequently experienced difficult extraction with the clinicopathologic parameters of POMC. Eighty two cases of POMC were retrieved from the Department of Oral Pathology, Seoul National University Hospital, and seventy were selected after scrupulous reexamaination of histopathologic and radiographic features. They were reviwed with respect to age, gender, site of involvement, clinical findings, and pathologic appearance. POMC occurred more frequently in males(41 case, 58.6%) than in females (29 cases, 41.4%), and they occurred over a wide age range, most commonly in the fourth decade (28 cases, 40.0%), and mean age was 44 years. Average duration of development of POMC after surgery was 20.7 years. The most common clinical manifestations at the time of admission was pain with swelling particularly in the buccal or retromolar area of affected side of the maxillary sinus.
