[Dynamics of the otoneurologic symptoms after complete and partial removal of a tumor of the acoustic nerve at different stages of its development].
The peculiarities of the dynamics of the entire complex of otoneurologic symptoms were studied in 60 patients with a tumor of the acoustic nerve in stages II and III of the disease after total (in 38) and partial (in 22) resection of the neoplasm. The data obtained bore evidence that the dynamics of the otoneurologic symptoms depended on the developmental stage of the tumor, its relation to the brain stem, and the character of the operation (total or partial removal of the tumor). Total resection of the tumor in stage II proved most effective: in the residual period both stem vestibular disorders and statokinetic and coordination disturbances were minimum or absent. In total removal of the tumor in stage III of the disease the regression of the symptoms was delayed and much less apparent. In subtotal removal of the tumor during stage II the symptoms regressed slightly or not at all. Symptomatology remained gross, irreversible or even frequently became more severe after subtotal removal of the tumor in stage III of the disease.
