Reviewing treatment guidelines: Is a 20% postoperative improvement in monosyllabic discrimination reliably expected after Cochlea implantation?

Background Cochlea Implantation represents a standard and has progressed through innovations. Reviewing guidelines in light of these developments is crucial. According to the guidelines of the German Society of Oto-Rhino-Laryngology (DGHNO), postlingually deafened patients should strive for a postoperative improvement in the audiogram of at least 20 dB and an increase in monosyllabic discrimination of more than 20% by the completion of follow-up therapy. It should be investigated how many patients do not achieve this goal and what factors contribute to it.
