Conclusion
In conclusion, this study supports the notion of differences in the subjective impairment in HRQoL among different types of CMED. These differences are independent from hearing. HRQoL is therefore not only associated with hearing, but also depends on other symptoms, such as tinnitus, discharge or vertigo. These aspects are considerably important and should be assessed using validated disease-specific questionnaires in clinical practice and research under the aim of supplementing the clinical history and providing standardized patient-reported information.
