Bilateral Accessory Middle Turbinate: A Rare Anatomical Varaition

Abstract

A bilateral accessory middle turbinate is an extremely rare anatomical variation. The embryological development of the nasal turbinate is a complex process during which anatomic variations may occur at multiple points. It is a bony prominence covered with soft tissue that originates from the lateral wall. In this study, we report a case of bilateral accessory middle turbinate projecting inferolaterally leading to chronic nasal obstruction .With the advent of imaging techniques like CT scans of paranasal sinuses,and diagnostic nasal endoscopy, the anatomical variations of nose and paranasal sinuses can easily be elicited. In this case after confirming the diagnosis by CT scan and diagnostic nasal endoscopy the patient was electively posted for Functional Endoscopic Sinus Surgery and bilateral accessory middle turbinates were resected out.
