We conducted a study to determine the prognostic reliability of preoperative computerized dynamic posturography (CDP) in patients undergoing surgical excision of an acoustic neuroma. Our goal was to determine the correlation between objective preoperative assessments of balance function and subjective postoperative patient self-assessments. To that end, we retrospectively reviewed the records of 21 adults who had undergone preoperative CDP, and we subsequently obtained their subjective assessments of balance function by follow-up telephone surveys at least 1 year postoperatively. We conclude that although CDP has proven to be useful in many aspects of balance evaluation, it did not appear to be a valuable predictor of subjective postoperative balance function in these patients.
