- Abstract
The facial nerve, Wrisberg.s intermediofacial nerve, the tympanic nerve cord, together with the lateral sinus, the external semicircular canal and the dura mater, are the most vulnerable elements in mastoid surgery because they can be injured during the intervention. Congenital anomalies of the facial nerve are closely related to middle and inner ear anomalies. A congenital paralysis is always accompanied by deafness, labyrinthine malformation and malformation of the middle and internal ear. In severe cases, facial bulbar nuclei atrophy occurs. In other cases of hemifacial hypoplasia and hypotonia, facial malformations associated with deafness in ear transmission appear. In these cases surgery is required. The approach should be taken with caution, since in such cases the canal of the facial nerve, the mastoid portion thereof, may often be open to all its scope. The stilo-mastoid hole is located at birth in its upper position near the eardrum.s house floor. Then, by development and lowering of the mastoid process, there is a shift of the stilo-mastoid hole in cranio-caudal direction and postero-above.
