(1) Use of otologic drill12345

Chooses inappropriate
burr and/or
repeatedly awkward
use of drill
Chooses appropriate burr and occasionally awkward
use of drill
Uses appropriate burr and drill effortlessly

(2) Use of microscope12345

or focus
Competent use of microscope but occasional inappropriate position
and magnification
Optimal visualization with appropriate microscope use

(3) Respect for surgical limits12345

Uses unnecessary
force or causes
damage by inappropriate use of instruments
Careful handling of tissue but occasional inadvertent damage to tissueConsistently handled tissues appropriately with minimal damage

(4) Time and motion12345

Many unnecessary movementsEfficient time/motion and maximum efficiencyClear economy of movement

(5) Knowledge of specific procedure12345

Deficient knowledge
and needed instruction at most steps
Knew all important steps of operationDemonstrated familiarity
with all aspects of operation

(6) Flow of operation12345

Frequently stopped
and unsure of next move
Some forward planning with reasonable progressionObviously planned course of operation with effortless flow

(7) Overall surgical performance12345
