title: [Cerebrospinal fluid rhinorrhea and otorrhea in tumors of the 8th nerve].
abstract: Nasal liquorrhea was encountered in 7 patients and auricular liquorrhea in 5 patients after operation for tumor of the eighth nerve. Nasal liquorrhea was consequent upon a sharp increase of intracranial pressure with formation of bone defects in the cribriform plate (4 patients) or upon destruction of the apex of the pyramid by the tumor or it occurred because the surgeon had opened the mastoid air cells during the operation (less frequently the cells of the pyramid of the temporal bone); in this case the cerebrospinal fluid seeped through the auditory tube into the nasopharynx and the nasal cavity (a condition called otogenic nasal liquorrhea, 3 cases) or through the tympanic membrane into the external acoustic meatus (1 case). The authors discuss the diagnosis and differential diagnosis of liquorrhea differing in the place of origin as well as the principles of surgical management.
