Ubiquity and attribution of Haller cells – A CBCT study

With the increasing popularity of sinus surgeries and the prolific advances in imaging technology, there is a major inclination towards the in-depth study of the anatomy of paranasal sinuses and the osteomeatal complex. Anatomical variations like deviation of nasal septum, paradoxical middle turbinate, double middle turbinate, and concha bullosa are seen in routine clinical examinations, but variations like Haller cells and Onodi cells require explicit radiological support. CBCT has the unique advantage of obtaining isometric images in all three planes with 3-Dimensional viewing and circumvent the obscurity of images due to superimposition. CBCT enables detection of even miniscule Haller cells along with discernment into the disease process and is a crucial preoperative planning tool. There has been a dearth of studies in the literature in this regard, and our study is a promising attempt to elucidate the significance of Haller cells with respect to surgical aspects.
