This is a review of the English literature relative to acoustic tumors from 1983 through 1988. In January of 1984, a similar article was published in this journal which reviewed the literature from 1979 through 1982. We have selected what we consider the most important articles from the hundreds that were published on this subject. Many other significant papers are not discussed. The material is presented in 11 categories: diagnosis, histopathology, treatment, hearing preservation, facial nerve preservation and repair, von Recklinghausen's disease and bilateral tumors, nonacoustic cerebellopontine angle tumors, instrumentation, basic research, complications of surgery, and miscellaneous topics. In each section the articles are briefly reviewed, and sometimes our personal point of view is expressed.
