Objective: A retrospective review of 18 cases with MSSS studied of 312 consecutive patients with maxillary sinusitis demonstrated by computed tomography of paranasal sinuses from January 2003 to November 2007. Age, sex, clinical manifestations and radiological findings were studied and compared. Results: All patients showed a orbital floor retraction toward the lumen of the affected sinus in sinus CT scans. All patients presented a homolateral enlarged middle meatus to the affected maxillary sinus. In 77,8% patients, affected maxillary ostium was obstructed by one or more anatomical causes, which was endoscopically and/or radiologically confirmed. In 55,6% patients, maxillary sinus was totally opacified. In all patients, the orbital content volume was increase in the affected sinus side.
