Abstract
|
|
|
|
Postoperative mucoceles of the maxillary sinus develop as a delayed complication of Caldwell-Luc operation, usually 10-20 years following the surgery. The general clinical presentations are swelling of the cheek, accompa-nied by dull maxillary facial pain and numbness. Enlarged postoperative cheek cysts infrequently protrude into the orbit and elevate the eyeball, causing double vision. Recently, we experienced a case of hypertropia caused by the protrusion of a postoperative cheek cyst into the orbit through widely defective inferior orbital wall. We were able to remove the cyst and identify the size and shape of the defective orbital floor using endoscopic transantral approach. The widely defective orbital floor was reconstructed with porous polyethylene via transconjunctival approach successfully.
