[A giant bilateral concha bullosa causing nasal obstruction]

Abstract

Pneumatization of the middle turbinate or concha bullosa is the most common anatomical variant of this structure. Although usually small and asymptomatic, a large concha bullosa may obstruct sinus drainage. We present an uncommon case of massive bilateral concha bullosa that produced complete obstruction of the left nasal cavity and partial obstruction of the right nasal cavity.
