Role of multi-detector CT in analysis of the greater and lesser palatine foramina

Abstract 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 w...

description Abstract 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.
