The clinical features were correlated with the coronal CT scan appearance of the paranasal sinuses of 49 patients who had received the Caldwell-Luc operation 16 to 58 years ago. The clinical diagnosis at the time of the CT scan was postoperative maxillary cyst in 22 patients, chronic sinusitis in 21 patients, trigeminal neuralgia in 3 patients, radicular cyst, postoperative ethmoid cyst and inverted papilloma in one patient each. The CT scans of the 91 operated maxillary sinuses showed obliterated cavity in 21 cases, small cavity in 46 cases, cystic formation in 24 cases. The authors speculated that some maxillary sinuses which appeared in CT scans as small cavities might cause the clinical symptoms of postoperative maxillary cyst in the future.
