Debris in the EAC from cholesteatoma or tumors may be confused with cerumen; accordingly, considerable care is required when debridement of the EAC is attempted. Debridement may be accomplished by using microinstruments or by aspirating ear canal contents with a No. 5 or No. 7 Barton suction device under direct vision through the otoscope or microscope. Irrigation of the ear canal is another option, but use of a pressurized irrigation system entails the risk of trauma.
