Abstract

Introduction : Foramen ovale of the sphenoid bone serves as an important landmark for neurosurgeons in the procedures involving the trigeminal nerve. Shape and size of the Foramen ovale is subject to vary as similar to other foramina. But, the Foramen ovale which is divided into two compartments is a rare variation. We report here a case of bilateral atypical foramina ovalia which is divided into medial and lateral compartments by an oblique bony lamina—the pterygoalar bar Case report : The medial compartment is regarded as a topographic counterpart to the Foramen ovale proper. The lateral compartment is regarded as canalis ovalis. Conclusion : The altered osseous morphology of this basicranial region may affect the course of the neurovascular structures which pass through the Foramen ovale. As a result, clinical symptoms could occur such as paresthesiae of the cheek and neuralgia resulting from compression of the mandibular nerve or its branches.
