Acoustic neuroma의 조기진단은 수술적 치료에 큰 도움이 침은 주지의 사실이다. Acoustc neuroma의 조기진단방법으로는 internal auditory meatus cisternography 가장 정확한 것으로 알려져 있으나 이를 위하여서는 무엇보다도 정상내이도의 계측이 필요하다고 하겠으며 내이도 계측 방법으로는 Camp, J.D.와 Cilley, E.I.L.등에 의한 Conventional roentgraphy, laminography, cisternography와 같은 간접적인 방법과 Amjad, A.H. 들에 의한 rubber cast를 사용한 직접적인 방법이 있다. 금번 저자들은 inpression material인 regular rubber base를 사용하여 연세대학교 의과대학 해부학교실에 있는 한국인 성인 두개골 41개를 대상으로 내이도에 대한 일련의 해부학적 계측을 하였기에 문헌적인 고찰과 아울러 그 결과를 보고하는 바이다.

Objective : To explore and analyze the influencing factors of facial nerve function retainment after microsurgery resection of acoustic neurinoma. Methods : Retrospective analysis of our hospital 105 acoustic neuroma cases from October, 2006 to January 2012, in the group all patients were treated with suboccipital sigmoid sinus approach to acoustic neuroma microsurgery resection. We adopted researching individual patient data, outpatient review and telephone followed up and the House-Brackmann grading system to evaluate and analyze the facial nerve function. Results : Among 105 patients in this study group, complete surgical resection rate was 80.9% (85/105), subtotal resection rate was 14.3% (15/105), and partial resection rate 4.8% (5/105). The rate of facial nerve retainment on neuroanatomy was 95.3% (100/105) and the mortality rate was 2.1% (2/105). Facial nerve function when the patient is discharged from the hospital, also known as immediate facial nerve function which was graded in House-Brackmann : excellent facial nerve function (House-Brackmann I-II level) cases accounted for 75.2% (79/105), facial nerve function III-IV level cases accounted for 22.9% (24/105), and V-VI cases accounted for 1.9% (2/105). Patients were followed up for more than one year, with excellent facial nerve function retention rate (H-B I-II level) was 74.4% (58/78). Conclusion : Acoustic neuroma patients after surgery, the long-term (${\geq}1year$) facial nerve function excellent retaining rate was closely related with surgical proficiency, post-operative immediate facial nerve function, diameter of tumor and whether to use electrophysiological monitoring techniques; while there was no significant correlation with the patient's age, surgical approach, whether to stripping the internal auditory canal, whether there was cystic degeneration, tumor recurrence, whether to merge with obstructive hydrocephalus and the length of the duration of symptoms.
