An ultrasonic bone aspirator (UBA) may reduce headache by minimizing subarachnoid bone dust dispersion. The feasibility of removing internal auditory canal (IAC) bone with a UBA is unknown. This study assessed volume and duration of IAC bone removal in clinical and laboratory settings.<\/jats:p><\/jats:sec><jats:sec><jats:title>Study Design:<\/jats:title><jats:p>(1) Retrospective review of radiologic data and intraoperative videos.

We then measured the time spent actively drilling IAC bone by analyzing operative videos. Finally, we measured bone ablation rates in a cadaveric temporal bone model using a drill and UBA.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p>The mean \u00b1 SD volume of IAC bone removed during surgery was 0.32 \u00b1 0.17\u00a0mL (n = 9). The time spent actively removing IAC bone with a drill was only 10.4 \u00b1 3.5\u00a0minutes, less than a third of the total IAC opening time of 34.2 \u00b1 13.1\u00a0minutes (n = 5). On cadaveric specimens, the UBA removed bone at 0.21 \u00b1 0.03 or 0.35 \u00b1 0.07 \u00b5L\/s at 15% or 50% power, respectively (n = 4). This extrapolates to 15.0 \u00b1 3.0 to 25.0 \u00b1 3.9\u00a0minutes to remove the same 0.32\u00a0mL from surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions:<\/jats:title><jats:p>The volume and duration of IAC bone removal during retrosigmoid VS surgery are small. Using a UBA at low power instead of a drill would extend the length of surgery by 5 to 15\u00a0minutes, with the theoretical potential for reducing
