Objectives: To determine the size and position of the Greater Palatine Foramen using CBCT.
Materials And Method: GPF was evaluated on 50 CBCT's which were obtained at the Division of Oral Medicine and Radiology, FDS, University of Peradeniya, The distance of each GPF to the mid maxillary suture (MMS), Anterior Nasal Spine (ANS), relationship of the GPF to the molar teeth and diameter were measured in different orthogonal planes using measurement tools integrated to the CBCT software.
Results: Mean diameter of the GPF in females and males were 3.72 mm for the right and 3.31 mm for the left and 4.56 mm and 4.30 mm. The antero-posterior distance measured from the ANS to mid GPF in axial sections among females was 45.70 mm and 44.81 mm for the right and left respectively whereas for males it was 48.37 mm and 47.6 mm. The distances in axial sections were 14.82 and 15.14 mm for right and left sides in females whereas in males it was 15.50 and 15.67 mm from the MMS. The same measurement in the coronal plane was 14.93 mm and 15.22 mm for females for the right and left GPF and was 15.63 mm and 15.49 mm in males respectively. There was a significant difference between the distance of ANS to the GPF on both sides and the diameters of GPF in both males and females (p < 0.005).
Conclusion: A significant difference was seen between the mean distance from the ANS to the GPF in left and right sides and the diameter of the GPF on the sides among the genders.

Pterygomaxillary separation (PMS) is an important step in Le Fort I osteotomy procedure, without which complete mobilization of the maxilla cannot be achieved. The aim of this study was to evaluate PMS patterns and their relationship with the anatomic measurements in Le Fort I osteotomy. In this prospective observational study cone beam computed tomography (CBCT) was used to measure the anatomic variables of the pterygomaxillary junction (PMJ) region including thickness, width, the distance between the most concave point at the lateral surface of PMJ and the greater palatine foramen (C-GPF), and the angle preoperatively, and the separation patterns postoperatively divided into the clean-cut type, maxillary sinus type, and the pterygoid fracture type.

When the bony palate is observed closely, multiple small foramina are seen on the palatal surface of the alveolar process. The authors hypothesized that the greater palatine nerve and artery might supply the maxillary teeth via the foramina on the palatal surface of the alveolar process and the superior alveolar nerve and artery.

Objectives: This study aimed to evaluate with ultrasonography (US) the location of GPF, the course of the GPA, and to measure palatal fibromucosa thickness.
Materials And Methods: This in vivo experiment was conducted on a group of healthy, young Turkish subjects. Using the US, the localization of the GPF, its diameter and opening type, maximum flow velocity (Vmax) and collateral branches (CB) of the GPA, and the thickness of the palatine mucosa were evaluated.
Age-dependent effects of Delaire facemask therapy for class III malocclusion : Impact on maxillary sutures and palatal morphology.

Background And Aim: Treatment effects of a combined rapid maxillary expansion (RME) and Delaire facemask (DFM) therapy have so far only been scientifically investigated through cephalometric analyses. The combination of cephalometric, dental cast and cone-beam computed tomography (CBCT) scan analysis was not yet used for investigating morphologic changes of the tooth-bearing palate. The aim of the present study was to determine whether patient age at treatment begin has an influence upon palatal length changes after RME/DFM therapy, and to what extent transverse palatal sutures contribute to these.

Objective: The goal of this research was to examine the morphological characteristics and exact anatomical positioning of the greater palatine foramen (GPF), with reference to nearby anatomical landmarks.
Material And Method: The research was performed on dry human skulls belonging to the Bosnian and Herzegovina population, using digital vernier calipers. The study began by noting the GPF's position relative to the maxillary molars, then measuring its distance from the median palatine suture (MPS), the incisive fossa (IF), the posterior border of the hard palate (PBHP), and the posterior nasal spine (PNS).
