title: The secondary nasal middle concha.
abstract: In this study a total of 175 coronal CT scans of the nasal cavity and paranasal sinuses have been investigated. A secondary middle concha was detected bilaterally in 12 (6.8%) out of 175 patients. In all cases, the ethmoidal infundibulum was placed anteroinferior to the lateral origin of the secondary middle concha. This structure did not obstruct the osteo-meatal complex in any of the 12 cases.
