ABSTRACT

Introduction: infraorbital ethmoidal air cells are actually pneumatized ethmoidal air cells that spread along the laminae papyracea and under ethmoid bulla and within lateral uncinate process. These cells often originate from anterior ethmoidal cells and are adjacent to infundibulum.According to some authors, the presence of these cells acts as a predisposing factor for recurrent sinusitis. Materials and Methods: This study was carried out using cone-beam computed tomography images of 104 patients in maxillofacial radiology archives of Jundishapur School of Dentistry, Ahvaz. All images were evaluated by software (NNT Viewer, QR, Verona, Italy), version 3.00 by two oral and maxillofacial radiologists. Patient information including age and gender, presence or absence of Haller’scells, affected side (left or right), its shape (round or oval), multilocular or unilocular, increased thickness of maxillary sinus mucosa (thickness greater than 3 mm), and orbital floor dehiscence was recorded in the information form. Finally, the statistical consultant was referred to for statistical analysis. Results: After examining the images, Haller’s cell was found in 35% of the patients which was more in females than males but there was no significant difference. People with Haller’s cell were significantly younger than people without Haller’s cell. Haller's cells were mostly unilateral, unilocular and oval in shape. Significantly more orbital floor dehiscence was observed in patients with Haller’s cell. There was no significant relationship between Haller’s cell and maxillary sinus thickening. Conclusion: Haller’s cell can cause vulnerable orbitis, especially when using surgical instruments. Therefore, a thorough evaluation of pre-operative bone structure is necessary to know the exact anatomy of paranasal sinuses.
