Two cases of @entity2103 (VII-Nm) were reported. The first case is a 41-year-old @entity1 who had 16 years of history of slowly progressive @entity3541 and @entity2167 . The @entity5 originated in horizontal portion of the right facial nerve, and extended epidurally into the middle cranial fossa, as well as medially along the facial canal to the C-P angle. The second case is a 55-year-old @entity1 with 16 years of history of progressive @entity3541 which was followed by @entity2167 . The @entity5 was found in the vertical portion of the right facial nerve, expanding in the petrous bone. Both @entity5 were removed surgically. 116 VII-Nm were reported in the literature including our 2 cases. Most were reported in the ENT field, and only 11 cases in the neurosurgical field. @entity3541 or @entity2167 is the initial symptom, depending on the site of origin in the facial nerve. VII-Nm can originate in any part of the facial nerve. The most common part of origin is the vertical portion where the @entity5 tends to expand locally, but it may extend extracranially along the facial canal. The @entity5 which originates in the tympanic portion tends to extend into the middle ear cavity. The @entity5 originating in the horizontal portion extends to the epidural space in the middle cranial fossa and/or medially along the facial canal. VII-Nm in the cisternal portion of the facial nerve extends to the posterior cranial fossa and produces the signs of @entity5 . Unlike the @entity5513 , VII-Nm is associated with marked @entity3541 .(ABSTRACT TRUNCATED AT 250 WORDS)
