Abstract
Background: Various ligaments present in the skull base are of clinical and surgical importance. One among them, is the petrosphenoid ligament (PSL). PSL may ossify either in a partial or complete form and forms the roof of Dorello's canal underneath which the abducens nerve passes. Studies argued both protective and adverse effects of the ossified PSL. Hence, the incidence of PSL ossification has become a relevant subject in clinical practice to radiologists, neurologists and neurosurgeons for understanding its potential role in abducens nerve compression.
Materials and methods: We have undertaken this study to investigate the incidence of PSL ossification from multidetector computed tomography (MDCT) images of the patients who had been referred to the Medical Imaging Department of Mubarak Al-Kabeer Hospital in Kuwait. We retrospectively assessed a total of 200 patients' head CT scans (400 petroclival regions) between January 2021 and June 2022 in which 59% were males (n = 118) and 41% were females (n = 82) aged between 18 and 91 years.
Results: A total of 37 patients (26 male, 11 female) aged between 18-84 years were presented with ossification of PSL. Among these 37 patients, 28 patients were presented with unilateral ossified PSL, and 9 patients were presented with bilateral ossified PSL, amounting to the total of 46 ossified PSL from 400 CT images of the petroclival regions (11.5%). The genderwise and sidewise occurrence of the PSL ossification seen in different age groups were not statistically significant (p > 0.05). Among all the ossified cases, there was no patient presented with abducens nerve palsy.
Conclusions: We believe our results provide baseline data in the region for understanding PSL ossification and its impact on the abducens nerve palsy.
期刊介绍:
"Folia Morphologica" is an official journal of the Polish Anatomical Society (a Constituent Member of European Federation for Experimental Morphology - EFEM). It contains original articles and reviews on morphology in the broadest sense (descriptive, experimental, and methodological). Papers dealing with practical application of morphological research to clinical problems may also be considered. Full-length papers as well as short research notes can be submitted. Descriptive papers dealing with non-mammals, cannot be accepted for publication with some exception.
