Is There a Relationship Between Maxillary Sinus's Inferior Pneumatisation and Sinonasal Variations? A Retrospective CBCT Study.

Objectives: This retrospective study aims to analyse alveolar and palatal process pneumatisation and their relationships with sinonasal variations using cone-beam computed tomography.

Material And Methods: The study included 500 patients aged 18 to 87 years, involving 1000 maxillary sinuses with cone-beam computed tomography scans. We examined the relationship between inferior maxillary pneumatisation and the following anatomic variations: Haller cell, concha bullosa, paradoxical concha, bifid concha, and septal deviation.
