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. The distance between the probe and the gingival margin (GM-P) was also measured to determine the course of GPA. Statistical analyses were performed using the chi-square test and the independent sample t-test, with the significance level set at 0.05.
Results: The study included 31 participants (16 females, 15 males; mean age, 23.77±0.92). GPF predominantly showed between the second and third molars (n = 15;48.4 %) and exhibited an anterior opening type(n = 25;80.6 %). The average diameter of GPF measured 5.52±1.76 mm, with a Vmax value of GPA at 14.39±5.07 cm/sec. Collateral branches were primarily observed at the first molar level (n = 23; 74.2 %). No statistically significant gender differences were noted in localization or opening type. However, GM-P at the second molar level was significantly greater in men than women(p < 0.05).
Conclusion: In understanding the anatomical structure of the palate, the US provides important clinical results regarding the anatomical measurement of the GPF, the GPA, and adjacent fibromucosa.

Morphometric analysis of the greater palatine foramen: a CBCT study in Portugal.

Purpose: The greater palatine foramen (GPF) represents the inferior opening of the greater palatine canal and is located posterolaterally on both sides of the hard palate. The aim of this study is to morphometrically characterise the GPF and to determine its anatomical relationships in a Portuguese population.
Methods: A retrospective study was performed based on the clinical records which included all permanent teeth erupted and a cone beam computed tomography (CBCT) of the entire maxilla.

The palate's morphological characteristics are of great importance, especially in periodontology, where the palatine tissue represents a source of tissue graft for multiple mucogingival surgeries. This study aimed to estimate the amount of donor tissue available through the average palatal height and average location of the greater palatine artery in the Saudi population according to age and gender. Digital casts for adult Saudi patients at the age of 18-60 years old with a mean age of 37.

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.
