Giant concha bullosa: a case report.

Concha bullosa is a relatively common anatomic variant that is in fact an enlarged pneumatized middle turbinate. We report a case of giant concha bullosa in a 21-year-old woman who had a history of nasal obstruction. Anterior nasal examination of the nasal cavity revealed bilateral nasal masses which were covered with normal mucosa. Nasal endoscopy of both nasal cavities was impossible because of total occlusion. Computed tomography showed a bilateral giant concha bullosa. Under general anesthesia, resection of lateral half of the concha bullosa was performed bilaterally by a transnasal endoscopic technique to achieve nasal airway patency.
