本组111例听神经瘤的研究中,106例经手术治疗,5例尸检。按照4级分类,Ⅰ类1例,Ⅱ类13例,Ⅱ类73例,Ⅳ类24例。病理分级与临床分期表现相符者81例,占72.98%;不符合者共30例,占27.2%。本组55例曾进行颅骨摄片,其中内听道有改变45例(18.82%),瘤体愈大或分级愈高,X 线内听道有改变者不愈多见,破坏也愈明显,如Ⅱ级为75%,Ⅲ级 In this study of 111 cases of acoustic neuroma, 106 cases were treated surgically and 5 cases were autopsy. According to the four-level classification, Ⅰ in 1 case, Ⅱ in 13 cases, Ⅱ in 73 cases, Ⅳ in 24 cases. 81 cases (72.98%) matched the clinical staging, and 30 cases (27.2%) did not meet the criteria. 55 cases of this group had skull radiography, including 45 cases of internal auditory canal changes (18.82%), the tumor is larger or higher grade, X-ray changes in the auditory canal more common, the more obvious damage, If Ⅱ grade is 75%, Ⅲ grade
