OBJECTIVE: To determine the risk of recurrent tumor in patients after incomplete resection of acoustic neuroma. STUDY DESIGN: Retrospective case review. SETTING: A tertiary referral center. PATIENTS: Thirty-nine patients were identified who underwent incomplete resection of acoustic neuroma between January 1988 and December 1993, and had a minimum follow-up of 3.5 years, at a mean of 6.2 years (range 3.5-10.2 years). INTERVENTION: Regular follow-up. using either computed axial tomography or magnetic resonance imaging yearly. MAIN OUTCOME MEASURES: Growth of residual tumor as determined by the increase in its greatest dimension on follow-up imaging studies and the necessity for additional treatment. RESULTS: Tumor regrowth occurred in 17 patients (44%). Ten patients (26%) required additional treatment during the follow-up period. CONCLUSION: This study suggests that incomplete resection of acoustic neuroma is associated with a significant risk of recurrent tumor requiring subsequent intervention.
