“…CT images of individuals with nasal pathology that may affect the measurement and individuals with poor imaging quality were excluded from the study. The study data were divided into three age groups, <20 years, 20-60 years, and >60 years, as adolescent, adult, and elderly, respectively (11)(12)(13). CT scans were performed with an 80-row Multidetector Computed Tomography (MDCT) scanner (Aquilion Prime, Toshiba Medical Systems, Nasu, Japan).…”

Aim: The greater palatine canal connects to the oral cavity through the greater palatine foramen. Preoperatively identifying the morphology of the greater palatine canal and greater palatine foramen is very important to avoid possible complications during surgery. This study aimed to evaluate the greater palatine canal and surrounding anatomical structures using computed tomography. Material and Methods: Images from 100 patients (35 female and 65 male) who had previously undergone computed tomography for various reasons were evaluated. The study data were divided into three age groups, <20 years, 20-60 years, and >60 years. Morphological parameters measured in this study included; diameter measurement from the widest part of the canal, length of the canal, beginning diameter of the canal, the ends diameter of the canal, localization of the canal entrance with respect to the third molar tooth, distance of the canal entrance to palatine suture. The values obtained from the measurements were compared in terms of age group, gender, and side. Results: The mean length of the canalis palatinus major was 15.19±4.38 mm. The diameter of the widest part of the canal and the end of the canal, and the distance between the canal entrance and the sutura palatina increased with age, but these increases were not statistically significant. Conclusion: Proper administration of anesthesia through the greater palatine foramen in maxillofacial surgeries and related applications requires a detailed understanding of the anatomy of the greater palatine canal, and the results of the present study will contribute to the understanding of this anatomy.

Objectives: This study aimed to evaluate the morphology and dimensions of the pterygoid hamulus (PH) and its changes by ageing in 20-40-year-old women in the Dental Branch of the Islamic Azad University of Sciences, Tehran, Iran. Materials and Methods: This cross-sectional study was conducted on cone-beam computed tomography (CBCT) scans from 258 women aged 20-40. The morphology, length, width, and angle of the PH in coronal and sagittal planes were investigated. Results: The average length of the right and left hamulus was 5.50±1.37 and 5.37±1.36 mm. The average width of the right and left hamulus was 2.16±0.72 and 2.11±1.06 mm. The average coronal angle of the right and left hamulus was 22.3±9.79° and 30.16±8.99°. The average sagittal angle of the right and left hamulus was 26.11±7.26° and 26.34±7.63°. In contrast with the sagittal angle, the right and left hamulus’s length, width, and coronal angles were not symmetrical. Slender morphology was the most frequent morphology, and it was symmetrical only in the 20-30-year-old age group. Finally, no variable was affected by ageing. Conclusions: Hamulus dimensions and morphology did not change with ageing in women aged 20-40. The PH symmetry varied by age group. Also, CBCT was a suitable tool for investigating hamulus changes. Clinical Relevance: Understanding the characteristics of the PH is crucial for diagnosing and treating various oropharyngeal and craniofacial conditions. It also aids in interpreting radiographs and diagnosing unexplained oropharyngeal pains. CBCT is a valuable tool for precisely visualising these structures, offering clinical insights into this previously understudied area.
