title: Large Doubly Septated Concha Bullosa: An Unusual Anatomic Variation.
abstract: Partial or total pneumatization of the middle turbinate is called concha bullosa. It's one of the most common anatomic variations of the lateral nasal wall. The exact reason of such pneumatization is not known. It can originate from the frontal recess, middle meatus, sinus lateralis or, less frequently, from the posterior ethmoid cells. Concha bullosa remains usually asymptomatic. However, an extensively pneumatized middle turbinate may constitute space-occupying mass, and thus, it may cause nasal obstruction. We report an extremely rare case of a patient with a large, doubly septated concha bullosa with four different sources of aeration.
