Evaluation of Morphology and Location of Greater Palatine Foramen (GPF) in Different Sagittal Facial Types: A CBCT Study in an Iranian Adult Population.

ABSTRACT:

Aim

The greater palatine foramen (GPF) transmits the greater palatine neurovascular bundle, and its position and shape directly affect palatal anesthesia, palatal surgery, and graft harvesting. This study aimed to evaluate variations in the location and morphology of the GPF across different sagittal maxillary growth patterns in an Iranian adult sample.

Methods

Sixty cone beam computed tomography (CBCT) scans were analyzed (20 per Sella-Nasion-A (SNA) angle: deficient, normal, excessive). GPF shape, location relative to the molar teeth, its position with respect to adjacent structures (including distances to the alveolar ridge, mid-palatal suture, contralateral GPF, and incisive foramen [IF]), and the angle between the mid-palatal suture, IF midpoint, and GPF midpoint were a
