Special Issue Information

Dear Colleagues,

The Special Issue aims to explore the latest advancements in and applications of biotechnological innovations in diagnosing, treating and managing hearing impairments. Hearing loss affects millions globally, significantly impacting the quality of life and communication abilities. This Special Issue seeks to provide a comprehensive overview of cutting-edge biotechnological approaches, including gene therapy, regenerative medicine, advanced auditory implants and nanotechnology, that are revolutionizing the field.

Recent research trends highlight the potential of gene editing tools such as CRISPR-Cas9 for correcting genetic mutations responsible for hereditary hearing loss, as well as the use of stem cells for regenerating damaged auditory cells. Additionally, the development of more sophisticated and miniaturized cochlear implants and hearing aids, enhanced with artificial intelligence, is improving patient outcomes. This Special Issue invites original research articles and reviews that discuss these innovations, their clinical applications and future prospects.

By bringing together diverse research and perspectives, this Special Issue aims to foster collaboration among scientists, clinicians and industry professionals, ultimately advancing the understanding and treatment of hearing loss through biotechnological means.

Introduction: Transimpedance matrix measurement (TIM) is an electrophysiological measurement protocol of the impedance patterns of electrode contacts within the cochlea. Several studies have reported that TIM is an effective tool for the identification of abnormal electrode array placement. However, the normative values for properly inserted electrodes, as well as correlation of the TIM patterns with the electrode position, are not completely determined. Objectives: The first aim of this study is to establish normative values of TIM measurements obtained in children with proper electrode array insertion and tip fold-over, with proper inner ear anatomy and in congenital anomalies. The second aim of this study is to compare TIM measurements in Slim Modiolar (SM) and in Contour Advance (CA) electrodes, as their position is different according to the modiolus proximity. Methods: A total of 55 pediatric patients were included in the study and underwent cochlear implantation. 62 intraoperative measurements were conducted in this group—50 in children with normal inner ear anatomy and 12 in children with inner ear malformations. After each implantation, a plain x-ray was obtained. Results: There were clear statistically significant differences in TIM patterns in patients where electrode fold-over was confirmed and between SM and CA electrodes. Conclusions: TIM is a promising technique for intraoperative analysis of electrode placement. TIM patterns differ and correlate consistently with the different models of array implanted. This study is the first to report TIM patterns observed in children with normal inner ear anatomy and in inner ear malformations. Full article
