Teaching nasal analysis to otolaryngology residents

This prospective cohort study was completed to evaluate a systematic approach for teaching nasal analysis to otolaryngology-head and neck surgery residents.

Residents from each post graduate year (PGY) were randomized to the control group or study group. Residents in the study group were given a 10-slide PowerPoint (Microsoft Corp) instruction on nasal analysis using the standard sequence of photographs and anatomic elements to describe in each view. All residents were given the standard sequence of photographs of 3 patients for assessment on nasal analysis. Then 12-14 weeks later all residents were re-evaluated using photographs of 3 new patients. The results were blinded and graded using an 18 point scale modified from a previous publication [1].

Twenty otolaryngology-head and neck surgery residents completed the study. Analysis was performed with and without multivariate regression modeling to adjust for PGY, sex, and number of rhinoplasties performed. The study group had overall higher scores in both the initial and follow up assessment, specifically with subsite-specific dorsal deviation, tip projection, and nostril symmetry. Neither group obtained high scores in facial symmetry, skin thickness, tip shape and contour, and radix position at initial or re-assessment.

Nasal analysis is a complex task. A lecture on a systemic approach to facial analysis given to a group of residents, who performed significantly better on facial analysis cases than controls. Further research in providing feedback, periods of rehearsal or testing, or focused selected elements with serial exposure can be considered.
