Rare anatomical variation of the inferior turbinate: two cases of concha bullosa with review of the literature

Inferior concha bullosa (ICB) is a rare anatomical variation characterized by pneumatization of the inferior nasal turbinate. It is usually asymptomatic and discovered incidentally on computed tomography (CT) imaging but may contribute to nasal obstruction or rhinosinusitis in certain patients. We present two cases of ICB diagnosed on CT imaging. One patient underwent endoscopic sinus surgery with resolution of symptoms, while the second was managed successfully with conservative medical therapy. These cases highlights the importance of considering ICB in the differential diagnosis of nasal obstruction and emphasizes CT imaging as the diagnostic modality of choice.
