Abstract This assay discuss the relationship between the facial nerve and the vestibulochochlear nerve . This close relation ship start at early fetal life. The facioacoustic (acousticofacial) primordium appears during the third week of life At weeks 5-6 Complete separation of the facial and acoustic nerves is apparent, and a discrete nervus intermedius develops., (Schaitkin, Eisenman,2000) We discuss the anatomy of facial nerve & vestibulochochlear nerve The facial nerve, or cranial nerve (CN) VII, is the nerve of facial expression. The pathways of the facial nerve are variable, and knowledge of the key intratemporal and extratemporal landmarks is essential for accurate physical diagnosis and safe and effective surgical intervention in the head and neck. - Central Connections - Cerebellopontine Angle and the Internal Auditory Canal -Intratemporal Course - Proximal or labyrinthine segment - Tympanic or horizontal segme - Mastoid segment -Extratemporal segme (May, Schaitkin,2000). |
