Torque speed characteristics of two mastoid drills were measured. Potential temperature elevations in temporal bones were calculated from these measurements. Measured temperature elevations in temporal bones drilled without irrigation agreed well with predictions. Irrigation was demonstrated to be of critical importance in minimizing thermal hazard from mastoid drills.
