CBCT Study of Maxillary Sinus Dimensions and Greater Palatine Canal Pathway: A Retrospective Analysis

January 24, 2026 updated by: Ghada Adayil, Cairo University

Radiographic Assessment of the Correlation Between Maxillary Sinus Dimensions and Greater Palatine Canal Pathway in CBCT Images (A Retrospective Study).

The CBCT-based radiographic evaluation will be used to identify, classify, and measure the anatomical parameters of the GPC and maxillary sinus. These data will serve as a pre-surgical diagnostic guide for clinicians when performing procedures involving the posterior maxilla.
