A variation of the infraorbital nerve: its potential clinical consequence especially in the treatment of trigeminal neuralgia: case report.

Objective: We report the case of a seemingly rare variation of a branch of the trigeminal nerve. This unusual finding is of practical importance to the neurosurgeon because ablation of this nerve(s) in such a case would require modification of technique. The existence of a bifurcated infraorbital nerve is also relevant for application of local anesthesia to portions of the face innervated by the maxillary nerve.

Ossification of ligaments near the foramen ovale: an anatomic study with potential clinical significance regarding transcutaneous approaches to the skull base.

Objective: There is paucity of information regarding the specific anatomy and clinical significance of ossified ligaments near the foramen ovale (e.g., pterygospinous and pterygoalar ligaments).

Peroneotalocalcaneus muscle.

Variations within the musculature of the lateral compartment of the leg are uncommon. However, clinicians and radiologists should be aware of anatomical alterations in this region when involved in diagnosis or imaging interpretation. The present report describes a well-developed muscle of the lateral compartment of the leg that inserted distally onto the talus and calcaneus.

Does the maxillary division of the trigeminal nerve traverse the cavernous sinus? An anatomical study and review of the literature.

Aim: Many authors have included the V2 segment of the trigeminal nerve as a component of the cavernous sinus. However, many authorities have stated that this part of the fifth cranial nerve is not within this intracranial venous sinus.

Materials And Methods: To further elucidate this potentially important relationship, 10 fresh cadaveric heads underwent injection of the cavernous sinus with blue latex or a cresyl-violet solution.
