    Unilateral loss of trigeminal nerve fibers at the ventral pons
    Author(s): Tabinda Hasan*

    The trigeminal nerve has the largest territory of sensory innervation across the head and neck. It leaves the lateral pons through a large lateral sensory and small medial motor root. Root Entry Zone is an anatomical landmark of great functional hierarchy where variants in nervous tract trajectories and arterial loops, may result in neurovascular conflicts leading to neuralgias. The sensory root holds clinical significance because it innervates sensory receptors of the head and neck. This case reports a cadaveric brain stem with significant loss/ hypotrophy of left trigerminal nerve fibers. Such forfeit (weather due to congenital hypotrophy or postnatal lesion) can lead to variable degree of sensory loss along the nerve course and the innervation of mastication apparatus, change in of cerebellopontine angel and cistern volumes. The clinical outcomes of missing fibers might be not only.. Read More»
