Comparative StudyDrilling simulated temporal bones with left-handed tools: a left-hander's right?
Left-handed trainees can be at a disadvantage in the surgical environment because of a right-handed bias. The effectiveness of teaching left-handed trainees to use an otologic drill designed for their dominant hand versus the conventional right-handed drill was examined. ⋯ The left-handed trainees learned bone drilling better with tools designed for the left hand. These tools may be incorporated into residency training programs for the development of surgical technical skills. Future studies should assess skill transfer between the left-handed and right-handed drills.

This study was intended to 1) identify preoperative predictors of difficult laryngoscopy and 2) determine the role of obesity in difficulty of obtaining adequate laryngeal exposure. ⋯ Obese patients and those with a Mallampati score of at least 2 posed a significantly higher risk of DLE. Preoperative identification of a potentially difficult airway may aid surgical planning and allow more effective communication with a collaborating anesthesiologist.

There is great interest in training surgeons in the technical aspects of their craft through simulation and laboratory-based exercises. However, there are as yet only a few objective tools to assess technical performance in a laboratory setting. This study assesses three potential objective assessment tools for a traditional otolaryngology laboratory exercise, temporal bone drilling. ⋯ This study validates EO, the GRS, and the TBC as measures of temporal bone drilling performance. Of these measures, the TBC correlates best with EO according to logistic regression and can be reliably used as an objective assessment of temporal bone drilling.
