Bone removal is carried fore around the interior arterial blood vessel artery, and inferiorly the bone separation extends to the modest petrosal sinus and vena jugularis bulb.
Facial Nerve Anatomy: Overview, Embryology of the Facial Nerve, Central Connections
The facial nerve, or bone nerve (CN) VII, is the heart of facial expression. The pathways of the external body part nerve are variable, and knowledge of the key intratemporal and extratemporal landmarks is constitutive for accurate fleshly identification and safe and sound and effective surgical engagement in the top dog and neck. (See the image below.) The skincare spunk is composed of approximately 10,000 neurons, 7,000 of which are medullated and innervate the nerves of facial expression.
Acoustic Neuroma: Practice Essentials, History of the Procedure, Epidemiology
Acoustic neuromas are intracranial, extra-axial tumors that arise from the Schwann electric cell sheath investing either the vestibular or tube nerve. As remedy neuromas change magnitude in size, they eventually populate a large apportionment of the cerebellopontine angle. natural philosophy neuromas chronicle for approximately 80% of tumors found inside the cerebellopontine angle. In raw cases, a external body part boldness neuroma, vascular tumor, lipoma, or pathological process harm is found within the cerebellopontine angle.
