Abstract :

INTRODUCTION: As functional endoscopic sinus surgery (FESS) is one of the advances in sinus surgery and is on peak now a days. Therefore understanding of anatomical variations of Accessory Maxillary Ostium(AMO) becomes essential for an endoscopic sinus surgeon in order to differentiate it from the natural ostium for safe and efficacious surgery in this region. MATERIAL AND METHOD:present study was carried on 150 CTscans(300 sides) of age >20years for presence of accessory maxillary foramen by Postgraduate Department of Anatomy in collaboration with Department of Radiodiagnosis and Imaging, Government Medical College, Srinagar RESULTS: In our study of 150 CT scans( total of 300 sides) presence of AMO( was seen in total 4sides which accounts 1.33%.3 AMO was present in posterior nasal fontanelle while in one case AMO was located in anterior nasal fontanelle. CONCLUSION:The radiologists and rhinologists must have complete knowledge of inconsistent location of these apertures and intricate topography of the middle meatus in any interventional endonasal endoscopic maxillary sinus surgery.
