  • Title: [Otoneurological symptomatology in tumors of the hypophysis with marked extrasellar growth].
    Author: Blagoveshchenskaia NS, Leushkina LN.
    Journal: Zh Vopr Neirokhir Im N N Burdenko; 1988; (2):24-8. PubMed ID: 3260431.
    Abstract:
    Otoneurological examination with the use of modern methods (electronystagmography, electrogustometry, supraliminal cupulometry, audiometry) showed that some type of disorders are encountered in 100% of cases of tumors of the hypophysis with marked extrasellar growth (vestibular disorders in 94% of cases, disturbed sensitivity in the nasal cavity in 55%, disorders of hearing and the sense of taste in 18%, disorders of the sense of smell in 17%). The otoneurological symptoms yield additional information on the direction of the tumor growth and, what is most important, on the degree of its effect on the brain stem parts of the diencephalic and posterior cranial level and on the subcortical structures. The otoneurological data allow judgement of the degree of compensation and extent of involvement of the stem parts of the brain and the subcortical structures. In parasellar growth of the tumor which caused an effect on the sympathetic plexus of the internal carotid artery the authors revealed distinct asymmetry of vegetovascular innervation of the nasal mucosa by means of their modification of Muk's test.
