58 cases of huge acoustic tumor were received surgical treatmeot(?)from Feb. 1962 to Aug.1967, Jul. 1971 to Ian. 1982. Separately in our hospital. Sex: female, 23, male; 35; age: 13~63 Yr.(peak freguency in middle age). The average duration of clinical course was about two years. Clinical manifestations often consisted of progressive headache, vomiting failing vision, papilloedema and increased intracranial pressure. But hearing loss, tinnitus were seldom seen as initial complaints in our group. Petrous pyramid x-ray film indicated enlarged internal auditory canal and destruction of the upper portion of the canal. It was difficult either to remove the huge tumor totally or to preserve facil nerve and hearing ability well. In our group 15 cases have received total resection and 43 cases subtotal resetion. The overall operative mortality was 10.2%, microsurgery technique played an important role in reducing the risk.

1962年2月~1967年8月和1971年7月~1982年1月,我们共手术治疗巨大听神经瘤58例。其中男性35例,女性23例。最小年龄13岁,最大年龄63岁,多见于中年人。病程常在1年以上,平均超过2年。本组病例临床表现多数为进行性头痛加重。呕吐、视力减退、视神经乳头水肿和颅内压力增高,而以一侧或双侧听力减退或耳鸣为首发症状者不多见。 X线见岩骨锥部内听道扩大或骨质破坏,常提示肿瘤为巨大型,这种巨大肿瘤的全切除或保留面神经及听力常较困难。本组病例均手术治疗,全切除者15例,部分切除者43例。病死率10.2%。应用显微外科手术,可降低病死率。

Using this method, 170 films of 85 cases were collected,the rate of accurate projection was 97. 6%, which was obviously superior than results reported by other methods before. A point was fixed at the head end of the X-ray table as the point O, then the central line of the X-ray tube was adjusted so as to perpendicular vertically to this point.

After many years exploration,the auther obtained a new method for taking X-ray films of the petrosomastoid cone of the head. Using this method, 170 films of 85 cases were collected,the rate of accurate projection was 97. 6%, which was obviously superior than results reported by other methods before. A point was fixed at the head end of the X-ray table as the point O, then the central line of the X-ray tube was adjusted so as to perpendicular vertically to this point. The point 1cm above vertically to the apex of the patient's mastoid process was aimed at the point O,then who's head was adjusted until the point 1cm below vertically to the lateral margin of the opposite eye socket was perpendicular vertically to the point O,and maintained at this position. The line which connected these two points on the head was corresponded with the position and trend of the petrosomastoid cone. Then the tube was tilted 45 degrees to the foot end of the table,and the distance between the tube and the point O as well as the position of the film was adjusted, then the film was exposed.

本文对岩骨轴位定标与定点摄影原理及投照方法作了研究,结果表明:通过头颅体表的两个定标点,即乳突尖向上及对侧眼眶向下各1cm,两定标点问的连线即为岩骨在颅内的位置及走向。在岩骨轴位摄影时,将定标点之一的乳突尖上1cm处对准台面定点,并使两定标点的连线垂直于台面定点,中心线通过台面定点向足端斜45°角。本文经85例对象共拍摄了170张岩骨轴位照片,结果投照位置准确率达97.6%

Lesions located in the internal auditory canal were previously considered surgica-lly inaccessible before the development of the transtemporal approaches by House in1960s. Since then, these techniques have been widely used in the world. Suprisinglythere were only few reports in Chinese literature. Here with 15 cases of internal au-titory canal microsurgeries were reported, including total decompression of the facialnerve for facial paralysis resulted from temporal boue fracture, Bell's palsy, herpeszoster oticus,...

Lesions located in the internal auditory canal were previously considered surgica-lly inaccessible before the development of the transtemporal approaches by House in1960s. Since then, these techniques have been widely used in the world. Suprisinglythere were only few reports in Chinese literature. Here with 15 cases of internal au-titory canal microsurgeries were reported, including total decompression of the facialnerve for facial paralysis resulted from temporal boue fracture, Bell's palsy, herpeszoster oticus, and removal of primary cholesteatoma, facial neuroma and acousticneuroma. Two main sub-approaches were adopted in the series, transtemporal suprala-byrinthine, in 12 patients, and translabyinthine in 3 patients. The surgical procedurewith some modifications was described. No serious complications occurred in thisgroup. An average 10 month follow-up was made with good results.

内听道位于岩骨深部,其中走行位听神经和面神经,所涉及的病变多与这些颅神经有关。内听道开口于小脑桥脑角区、止于内听道底,与脑干、小脑、内耳的前庭和耳蜗相毗邻,手术解剖复杂。作者报告自1989年~1991年采用经颞骨途径行内听道手术15例,其中经迷路上进路12例,经乳突迷路进路3例。所行手术包括颞骨纵行骨折面神经麻痹3例,贝尔氏面瘫4例,耳带状疱疹1例,均行面神经全程减压,颞骨原发性胆脂瘤2例,面神经鞘瘤2例,肿瘤切除后行面神经移植吻合;内听道听神经瘤3例。本文仅就手术技术及随访结果进行讨论。
