The majority of included studies showed CWU to result in more disease recidivism compared to the CWD technique in adult patients with a primary acquired cholesteatoma. If recidivism risk is the most important factor to consider a certain surgical technique, we recommend application of the CWD procedure. However, many additional factors in patient care will define the best treatment decision, such as residual hearing and access to health care. Our recommendations are based on Level II evidence, which underlines the need for future high-level evidence studies.

Overall adherence to CPG indications when requesting DFT in primary care patient with GE was 17%. Implementation of PCR-based DFT was not associated with a change in CPG adherence.
