Concha bullosa

Concha bullosa in CT

A concha bullosa is a pneumatized (air-filled) cavity within a turbinate in the nose.[1] (Concha is another term for turbinate.) Bullosa refers to the air-filled cavity within the turbinate.[1] It is a normal anatomic variant seen in up to half the population. Occasionally, a large concha bullosa within a turbinate may cause it to bulge sufficiently to obstruct the opening of an adjacent sinus, possibly leading to recurrent sinusitis.[1] In such a case the turbinate can be reduced in size by endoscopic nasal surgery (turbinectomy). The presence of a concha bullosa is often associated with deviation of the nasal septum toward the opposite side of the nasal cavity.[2] Although it is thought that sinusitis or sinus pathology has relation to concha bullosa, no strong statistical correlation has been demonstrated.[1]
