在75例头颈部球瘤中,发生颅神经瘫痪者占37％;侵入颅内者占14.6％;出现颈静脉孔综合征者占5％。肿瘸侵入后颅窝者75％有舌下神经受侵犯。肿瘤侵入中颅窝者50％有Horner氏综合征。侵及中枢神经系有颅神经瘫痪者(不包括第Ⅶ颅神经)占52％。耳部检查所见及Ⅶ颅神经瘫痪与肿瘤的可切除性、中枢神经系侵犯及预后无多大关系。 In 75 cases of head and neck bulbomas, 37% of cases occurred cranial neuralgia; 14.6% of invaded cranial nerves; and 5% of jugular venous syndromes. Invading the posterior cranial fossa, 75% of the patients had invasion of the hypoglossal nerve. 50% of tumors invading the middle cranial fossa have Horner’s syndrome. Invasion of the central nervous system with cranial nerve spasm (excluding the VII cranial nerves) accounted for 52%. The ear examination and VII cranial nerve spasm and tumor resection, central nervous system invasion and prognosis have little to do.
