Two Cases of Postoperative Cheek Cyst with Exophthalmos / 대한이비인후과학회지

ABSTRACT

Postoperative cheek cysts develop as a delayed complication of Caldwell-Luc operation, usually 10 to 20 years following the surgery. The general clinical presentations are swelling of the cheek, accompanied 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 two cases of exophthalmos caused by the protrusion of a postoperative cheek cyst into the orbit. One patient, a 39-year-old man, underwent Caldwell-Luc operation 21 years ago, and the other patient, a 53-year-old man, 36 years ago. We were able to secure an accurate measurement of the defective orbital floor using the preoperative 3-dimensional reconstruction CT scan. The postoperative cheek cyst was completely removed using the endonasal and transantral endoscopic approach, and the widely defective orbital floor was reconstructed with Medpor(R).
