Résumé
Postoperative maxillary cyst (POMC) is relatively common complication among patients who underwent Caldwell-Luc surgery. Patients with POMC usually have no symptoms, although cyst extension can result in bone destruction or cystic infection with pain. The trigeminal nerve consists of the ophthalmic nerve, maxillary nerve, and mandibular nerve. Among these branches, the maxillary nerve runs to the lateral and frontal sides of the maxillary sinus wall. POMC can rarely lead to trigeminal neuropathy caused by cyst enlargement that compresses some branches of the trigeminal nerve. Recently, we experienced a case with trigeminal neuralgia due to POMC. The patient was successfully treated with inferior meatal antrostomy. We report this rare case with a literature review.

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).

The postoperative cheek cyst develops as a delayed complication, usually 10 to 20 years after the Caldwell-Luc operation. The most common symptoms are swelling or pain of the cheek and the mucogingival fold of the maxilla. The pathophysiology of postoperative cheek cyst is under debate. Clinically bony destruction of infraorbital portion of orbit is rare. Recently, we experienced a case of a postoperative cheek cyst which had a infraorbital protrusion, so we report this rare case with the review of literatures.
