Concha bullosa is a term used for enlarged middle turbinates filled with air. Most of the time they are asymptomatic but with their mass effect they can cause stuffy nose. Deviated nasal septum can be associated with this compromising other side of the nose as well. Concha bullosa may itself become diseased sometimes. Concha bullosa may obstruct the drainage of maxillary sinus giving rise to maxillary sinusitis as well.
Treatment involves removing a part of bone on its lateral side with preservation of mucosa (lateral turbinectomy).
