Abstract

This study was undertaken to determine the association of sinus anatomy and anatomic variants with the predisposition for such a complication.</p> <p>All adult patients (n = 16) with orbital proptosis were identified from a prospectively‐collected database at a tertiary institution. These were compared with a series of randomly‐selected patients (n = 50) diagnosed with chronic sinusitis and who had undergone sinus computed tomography. The presence or absence of supraorbital ethmoid air cells (SOECs) was noted and compared between the 2 groups. The primary sinus anatomy responsible for the proptosis was also identified. Statistical analysis was performed using the chi squared test.</p> <p>Sixteen patients with orbital proptosis were identified, of which all but 1 had SOECs present.
