This bone lesion filled the largest part of the concha bullosa
One study20 reported that 73% subjects with concha bullosa
suffered from paranasal sinus inflammatory disease; but 78% subjects without concha bullosa
also indicated some forms of inflammatory disease.

At the time of surgery, the left concha bullosa
was entered anteriorly (figure, B) and the lateral portion of the concha bullosa
were addressed in 3 cases, and agger nasi cells in 1 case.

Pneumatization of the nasal turbinates is a common anatomic variant that most frequently occurs as a concha bullosa
of the middle turbinate.
