Paper Abstract

This is a series of sixty consecutive sitting position suboccipital extirpations of acoustic neuromas operated between January 1986 and March 1990 where a CO2 laser was used in an attempt to preserve patients' facial and cochlear nerve function. Following surgery, four patients had normal and one had near-normal hearing (PTA<30 dB, SD>70%). These patients had tumors of 4, 3.2, 3, 1.5 and 1.2 cm in the greatest dimension. Two other patients (tumor size, 1.9 and 1.2 cm) have useful hearing (PTA<50dB, SD>50%) and four patients have sufficient hearing for the successful use of a hearing aid (4.6, 2.8, and 2 cm). One of thirty-two patients with the perception of useless hearing improved to useful hearing following surgery.
