A Rare Concha Variation: Coronal Cleft

Abstract

Nasal turbinates are embryologically derived from a series of outgrowths from the foetal lateral nasal wall. These outgrowths form a series of ridges, referred to as “ethmoturbinals” and have several vital functions. Several different turbinate variations have been reported so far. The authors presented 3 patients of coronal clefted concha who were diagnosed with magnetic resonance imaging. Computed tomography scans and nasal endoscopic examinations are also performed subsequently. These patients are the first coronal clefted concha cases in the literature and also the first radiological study defining concha cleft. This shows paucity of data documenting variations in the lateral nasal wall. Understanding the anatomy and the anatomic variations of the nasal cavity and nasal turbinates is critical to guide the procedure due to its close proximity to vital structures such as orbita and skull base, especially for functional endoscopic sinus surgery that is a widely used technique nowadays.
