Maxillary sinus atelectasis.
Two patients are presented with maxillary bone loss and atelectasis of the sinus walls in association with chronic subclinical maxillary sinusitis. Maxillary sinus atelectasis results in a mild cosmetic deformity, but may also cause diplopia by involving the orbital floor. Ostial obstruction and inflammation-mediated osteopenia are postulated to be the responsible mechanisms. Surgical treatment of the sinusitis may prevent progression of the bone loss.
