[Facial nerve anomalies found at surgery (author's transl)]. 1975

J Theissing

Facial nerve anomalies found at surgery are reported, and are classified as Minor and Severe. A solitary malformation is rare. Duplication of the nerve in its tympanic segment as well as branching within the mastoid bone with an unusual route close to the mastoid cortex was also observed. Malformations of the nerve in connection with other anomalies of the ear were encountered in 20% of all ear anomalies that underwent surgery. There was no direct correlation between the degree of the ear deformity and the facial nerve malformation. Two cases of severe malformations were seen whereby in one with a minor ear deformity the nerve was seen lying at the level of the tympanic membrane. In the other instance the nerve had an additional well developed duplication in the correct position, although a lesion on the duplicated nerve showed that it was non-conductive.

D009493	Neurosurgery	A surgical specialty concerned with the treatment of diseases and disorders of the brain, spinal cord, and peripheral and sympathetic nervous system.	Neurosurgeries
D004423	Ear	The hearing and equilibrium system of the body. It consists of three parts: the EXTERNAL EAR, the MIDDLE EAR, and the INNER EAR. Sound waves are transmitted through this organ where vibration is transduced to nerve signals that pass through the ACOUSTIC NERVE to the CENTRAL NERVOUS SYSTEM. The inner ear also contains the vestibular organ that maintains equilibrium by transducing signals to the VESTIBULAR NERVE.

D005154	Facial Nerve	The 7th cranial nerve. The facial nerve has two parts, the larger motor root which may be called the facial nerve proper, and the smaller intermediate or sensory root. Together they provide efferent innervation to the muscles of facial expression and to the lacrimal and SALIVARY GLANDS, and convey afferent information for TASTE from the anterior two-thirds of the TONGUE and for TOUCH from the EXTERNAL EAR.
