The German Society of Otorhinolaryngology, Head and Neck Surgery (DGHNO-KHC) and the German Academy of Otorhinolaryngology, Head and Neck Surgery (DAHNO-KHC), in cooperation with the relevant working groups, have developed expert certificates for the subfields "head and neck onco-surgery" and "paranasal sinus and (anterior) skull base surgery." The aim was to demonstrate the applicants' expertise in the respective subfield, in line with international standards. For the subspecialty "surgical otology, neurotology, and lateral skull base surgery," the Association of German-Speaking Audiologists, Neurotologists, and Otologists (ADANO) has developed a set of criteria for obtaining the expert certificate "Otological, neurotological, and (lateral) skull base surgery." This personal certificate can be used to demonstrate individual expertise. Practical implementation is carried out by an independent certification body (ClarCert GmbH) on behalf of the DGHNO-KHC and in cooperation with the DAHNO-KHC and the respective working groups. Applications for the expert certificate can now be submitted by members of the DGHNO-KHC and the DAHNO-KHC.
