Which small acoustic neuromas need surgery? The influence of magnetic resonance and air CT meatograms.
Small acoustic neuromas which are mostly or completely confined to the internal auditory meatus can be demonstrated by air meatography and magnetic resonance. MR has significant advantages over CT but either technique can demonstrate growth rate if appropriate repeat examinations are made. Three cases, showing variable ages, presentation and growth rates are described and considerations regarding the advisability of surgery in elderly patients discussed.
