Abstract:

Background: Knowledge of the anatomy constitutes an integral part in the total management of patients with Sinonasal diseases. The aim of this study was to obtain the prevalence of Sinonasal anatomic variations in Mongolian population and to understand their importance and impact on the disease process, as well as their influence on surgical management and outcome. Materials and methods: This study is prospective review of retrospectively performed normal computed tomography (CT) scans of the nose and paranasal sinuses in adult Mongolian population. Results: Of all CT scans that were reviewed, 53.7% were of women patients and 46.3% were of men patients. The mean age of the study sample was 45.6±16.3 years. The most common anatomic variation after excluding agger nasi cell was pneumatized crista Galli, which was seen in 98.8% of the cans. Anatomic variants with a potential impact on operative safety included Haller cell (13.3%), concha bullosa (20.5%)and paradoxical middle turbinate (27.3%). In our study, we compared the measurements between anterior ethmoid artery and adjacent anatomical structures in two groups. Conclusion: A wide range of regional differences in the prevalence of each anatomic variation exists. Understanding the preoperative CT scan is substantially important because it is the road map for the sinus surgeon. Detection of anatomic variations is vital for surgical planning and prevention of complications.
