Evaluation of Pterygoid Hamulus Dimensions in Completely Edentulous Patients Using Cone Beam Computed Tomography
Abstract:
The inferior border of the medial pterygoid plate extends to form the
pterygoid hamulus (PH). The PH's length and location are crucial for these
functions. The PH’s morphology helps in interpreting the imaging and also provides
information regarding anatomical determinants to limit the posterolateral
borders of maxillary complete dentures. This can also aid in gender
identification in forensic situations. This study analyzed 80 CBCT scans from
40 male and 40 female patients (ages 25–67, median 38). Significant differences
were found in pterygoid hamulus length between sexes: males had longer hamuli
on both the right (8.840±0.299 mm vs. 7.940±0.349 mm, P=0.000) and left sides
(7.899±0.419 mm vs. 7.277±0.271 mm, P=0.002). However, no significant
differences in hamulus width were observed between males and females. These
findings suggest length variations could be useful in clinical and
anthropological contexts. Dimensions of pterygoid hamulus in completely
edentulous patients will aid the clinician in precisely recording the posterolateral
borders of maxillary dentures; this can also aid in gender determination in
fragmented skulls in forensic applications.
