AbstractHeadache and depression were studied in patients who had undergone operation for acoustic neuroma. A questionnaire with headache and Beck Depression Inventory scale were sent to 228 patients, of whom 192 (84%) responded. Preoperative headache was reported by 61 (32%) of the respondents (47 migraine and nine tension-type headache) and 122 (64%) respondents had postoperative headache (15 new migraine and four new tension-type headache). The new postoperative headache was chronic (>/=3 months) in 86% and continued at the time of the survey in 55% and presented typically as severe short-lasting attacks provoked by physical stress, bending or coughing. Non-steroidal anti-inflammatory drugs were effective in most cases. Depression (usually mild) occurred in 24% of the respondents, being significantly more common in prolonged postoperative headache patients. The operation doubled the prevalence of headache (from 32% to 64%). Headache after acoustic neuroma operation appears to be a specific subgroup of postcraniotomy headache.
