Eligibility
Inclusion criteria
Inclusion criteria: • 16 years of age or older. • patients who underwent a surgical procedure (canal wall up tympanoplasty) for eradication of primary acquired or recurrent 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 or 1,2 and 4 kHz. • capable and willing to participate in a follow-up study of three years
Exclusion criteria
Exclusion criteria: • 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) • 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.)
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1.The degree of hearing loss (in average air-bone gap (dB))and high and low Fletcher index in each year of follow-up after primary cholesteatoma surgery | — |
Secondary
| Measure | Time frame |
|---|---|
| 2. The estimated costs of three years follow-up (especially in Observational CWU follow-up) 3. The outcomes of health related quality of life questionnaires (EQ-5D, OQUA, AIAHD)in each year of follow-up after primary cholesteatoma surgery. 4. The number of additional surgeries with cholesteatoma present (number of residual and recurrent cholesteatoma) 5. The number of additional surgeries without cholesteatoma to improve the hearing 6. The number and nature of the complications | — |
