Bilateral accessory middle turbinate presenting as double middle turbinate: A unique case report.

ABSTRACT

Many anatomical variations of the middle turbinate (MT), including pneumatized, paradoxically curved, bifurcate, trifurcate, secondary, and accessory, have been described. The most common is pneumatized MT (concha bullosa), but other less common variations may also impact the outcome of clinical management. Anatomical variations of the MT, particularly with a concomitant deviated nasal septum, tend to obstruct the middle meatus leading to disruption of the normal sinus drainage and worsening the symptoms of rhinosinusitis. By recognizing the unique anatomical variant by endoscopy or imaging will help us to improve the management. We report an endoscopic presentation of a rare accessory MT.
