Abstract
OBJECTIVE
To develop a time-sensitive, standardized rubric for cadaveric temporal bone dissection for otolaryngology resident education.
METHODS
This is a five-year prospective cohort study that evaluated otolaryngology resident performance during sequential cadaveric temporal bone dissection courses at a single otolaryngology residency training program. A canal-wall-up mastoidectomy with a facial recess approach was performed adhering to a 30-minute time limit and graded according to a standardized rubric. Main outcome measures included: (1) correct structure identification and (2) injuries sustained to structures as compared by resident post-graduate year (PGY) level.
RESULTS
Thirteen residents were evaluated from October 2012 to March 2017. This included 57 individual graded exercises performed over ten dissection courses. The average score for PGY-2 residents was lowest (68.9), and PGY-5 residents achieved the highest average score (87.7). Junior residents correctly identified fewer structures (77.5%) when compared to senior residents (91.3%), p < 0.0001. Correct performance of a facial recess approach was achieved by 100% of senior residents, but only 59.3% of junior residents (p = 0.0003). The percentage of major injuries, which included the facial nerve, tegmen, labyrinth, and ossicular chain, decreased each PGY-level from a maximum of 17% by PGY-2 residents to a minimum of 5% by PGY-5 residents.
CONCLUSION
Senior residents correctly identify more structures and are able to complete a facial recess approach with higher fidelity when subjected to a time-sensitive graded mastoidectomy rubric.
