Bifid inferior turbinate: a report of two cases.

Nasal turbinates are functionally important structures which extend from the lateral nasal walls to the nasal cavity. Lateral nasal wall anomalies are usually asymptomatic lesions which are incidentally detected. The most common variation of the lateral nasal wall is the pneumatization of turbinates. Anatomical variations of paranasal structures may present confusing intranasal landmarks. This may cause challenges in endoscopic sinus surgery. Bifid inferior turbinate is an extremely rare condition. In this article, we present two cases with bifid inferior turbinate. This variation should be kept in mind as a rare cause of nasal obstruction.
