Comparison of computer tomography and translabyrinthine surgery in the assessment of acoustic neurinoma.
In a series of 53 acoustic neurinomas removed by translabyrinthine surgery, measurement technique focused on maximum tumor size estimated with computed tomography (CT) compared with maximum size determined at surgery. Fifty-three tumors varying in size and location were evaluated. Ten small tumor not found with initial CT were identified at CT revision. Of the 34% which could not be seen with CT, all but two were less than 15 mm in diameter, indicating a lower limit for CT detection of 15 mm.
