Giant concha bullosa.

Concha bullosa is the most frequently encountered anatomical variation of the lateral nasal wall characterised with pneumatisation of the middle concha. The incidence of middle concha bullosa varies between 14% and 53%. Patients may often complain of nasal congestion and may in some cases suffer episodes of recurrent acute rhinosinusitis. In this article we present a case of nasal obstruction with an unusually large concha bullosa.
