“…The same most frequent location (opposite M3) was reported by Shalaby et al [9] in their study on Egyptian skulls (84%). Our results also match with Varalakshmi et al [6] and Beetge et al [10] who stated that GPFs were close to the third maxillary molar in 69.8% and 66.65% of their cases, respectively.…”

“…These results are almost close to most prior studies [4,11]. In the study of Beetge et al [10], the mean GPF dimensions were an A-P of 5.22 mm and an L-M of 2.81 mm. Shalaby et al [9] measured the mean AP as 4.86 ± 0.9 mm on the right side and 4.78 ± 1.01 mm on the left.…”

“…Despite numerous studies, there is still no agreement to whether the position of GPF is prone to ethnic variability. The cause of GPF position diversity may be due to the difference in the quality of procedures performed, as well as the way the GPF was related to maxillary molars [10,11]. Despite differences in the methods of assessment of GPF, the dimensions did not significantly differ among studies.…”

Background: The objective of this study was to assess variation in number, size, shape, and location of greater and lesser palatine foramina using multiple anatomical landmarks through data obtained from adult head CT scans. CT skulls of 200 adult persons were included in this study. There were 100 males and 100 females, aged from 22 to 65 years old. An e-film DICOM viewer version 2 was applied to estimate morphological parameters and to calculate the linear measurements related to the greater palatine foramen. Results: On the basis of CT findings, regarding the position of GPF in relation to maxillary molar teeth, the most frequent location was opposite the third maxillary molar (41%). Regarding the dimensions of the GPF, the mean AP diameter was 3.94 ± 1.13 mm on the right side and 4.22 ± 1.21 mm on the left. The mean LM diameter was 2.17 ± 0.59 mm on the right side and 2.28 ± 0.74 mm on the left. It was concluded that the GPF was AP elongated in 90.5% and circular in 9.5% of the examined CT scans. Linear measurements from the center of GPF to surrounding anatomical landmarks were done and showed no statistically significant difference existed between sides, but a statistically highly significant difference existed between males and females. Conclusions: Proper localization of GPF is important to facilitate therapeutic, local anesthetic, and surgical manipulation in the maxillofacial region. Based on CT findings, we demonstrated that the GPF is most often located opposite the M3 in the majority of the cases. The maxillary molars are the best landmarks for locating the GPF.

“…In surgeries related to posterior maxilla, then it comes to the oral cavity through the GPF in the Greater palatine canal (GPC) [1]. The GPN supplies the soft and the hard tissues of the palate and gives branches in the GPC.…”

“…The GPN supplies the soft and the hard tissues of the palate and gives branches in the GPC. The maxilla, palate, palatal glands with its mucoperiosteum and gingiva are innervated by the neurovascular bundle formed by the greater palatine nerve together with the greater palatine artery [1]. Finding accurate position of the GPF may resolve various problems in administering local and regional anesthesia during surgeries of the cleft palate, maxillary sinus or palatal free vascular flaps [2].…”

Archaeological investigation of the dentoalveolar complex in situ within a human skull requires detailed measurements using non-invasive techniques. Standard macroscopic and radiographic methods have limitations but large volume micro-computed tomography (LV micro-CT) scanning has the potential to acquire data at high resolution in microns. In this study, archaeological specimens are analyzed using three-dimensional data visualization software from LV micro-CT scans with the aims of (1) determining whether LV micro-CT can act as a single technique to provide detailed analysis of the dentoalveolar complex and (2) how findings from the LV micro-CT technique compare with standard methods. These aims are explored by measuring a range of human skull specimens from a rare archaeological sample requiring non-invasive methods, for multiple dental and alveolar bone health categories. The LV micro-CT technique was the only method to provide a full range of detailed measurements across all categories studied. A combination of macroscopic and radiographic techniques covered a number of categories, but the use of multiple methods was more time consuming, did not provide the same level of accuracy, and did not include all measurements. There were high levels of reproducibility for intra-operator scoring and good inter-operator agreement from four operators with one operator whose results were outliers. As a further investigation of the potential of the LV micro-CT technique, an additional individual, a fragile, fragmented skull of an infant was studied. This investigation confirms the value of LV micro-CT scanning as a non-invasive, accurate, single technique for the extensive analysis of the dentoalveolar complex within archaeological skulls, which also allows the relationship of different tissues to be studied in situ.
