Randomized Controlled Trial
Reliability of the Welling scale (WS1) for rating temporal bone dissection performance.
To determine the inter- and intrarater reliability of using a new scale (Welling scale) for resident evaluation of temporal bone dissection performance. ⋯ The Welling scale can be used reliably to assess temporal bone dissection performance where performance is measured by assessment of end product (mastoidectomy with facial recess approach).
