Accessory spine of the foramen ovale
open access
Abstract
The objective of this study was to provide a morphometrical analysis of the accessory spine which exists within the lumen of the foramen ovale, and to find out if that structure could mechanically irritate the mandibular nerve. A bifid spine was perceived in the macerated skull of an adult individual. It was located in the anterior part of the left foramen ovale. The overall length of the spine was measured as 1.8 mm. The spine has the homogenous structure, and show high level of mineralization. We conclude that the accessory spine did not compress the mandibular nerve, and the foramen ovale provided enough space for the nerve passage. Probably, these structures remained in anatomical accordance without causing any neurological symptoms.
