Inclusion criteria RCT
* 18 years of age or older.
* patients who underwent a surgical procedure (canal wall up tympanoplasty) for eradication of primary or recurrent acquired cholesteatoma
* primary surgery at a maximum of 11 months prior to the start of the study.
* patients with normal to mild conductive hearing loss, defined as:
mean air-bone gap of less than or equal to (*) 20dB on pure tone audiometry at frequencies of 0.5, 1 and 2 kHz .
* capable and willing to participate in a follow-up study of three years
* patients who underwent a canal wall down tympanoplasty procedure as last ear surgical procedure (patients with a canal wall down procedure in the last 10 months will be requested to participate in the cholesteatoma observational study, which is an anonymous follow-up study of usual care in post-cholesteatoma surgery patients without randomization);* patients with a moderate to severe average air-bone gap of more than (>) 20 dB (patients eligible for a chain reconstruction will be requested to participate in the cholesteatoma observational study);* patients not capable to undergo a MRI (claustrophobic, metal parts or implants in the body etc.)
