Strategy and benefits of acoustic neuroma searching

Advances in audiological, radiological and microsurgical techniques have enabled otologists to diagnose and excise very small acoustic tumours with a low morbidity and mortality. Is this cost effective? In an attempt to answer this question, an analysis of 66 cases of surgically treated acoustic neuromas is presented. This represents part of a series of skull base procedures carried out at Addenbrooke's Hospital over the last five years. As a result of this work an investigative protocol is suggested. By studying the relative morbidity of early and late surgical intervention in these cases, and by costing the exercise, the justification for early diagnosis and treatment is presented both in financial and human terms.
