Special Issue Information

Dear Colleagues,

Hearing rehabilitation holds a central position within the field of otolaryngology, encompassing both conservative options such as conventional hearing aid provision and surgical strategies such as tympanoplasty, vibroplasty, cochlear implantation and the application of brainstem implants. The significant progress in medical technology is noteworthy, particularly in enhancing the functionality of passive middle ear implants and implant couplers for active middle ear implants. Furthermore, advances in the development of electrode arrays and signal transmission for cochlear implants are evident. Future innovative strategies, such as photo-optical signal transmission and the development of neurostimulatory feedback systems, underscore these advancements. Additional opportunities lie in the integration of artificial intelligence into signal transmission processes, as well as the genetic diagnosis and therapy of hearing impairments.

Collectively, these advancements contribute to an increasingly individualized, if not personalized, approach to care. Consequently, the consultation process for determining the optimal solution for hearing rehabilitation in individual situations has become more complex. The compilation in this Special Issue aims to assemble the latest clinical advances in medical and surgical hearing rehabilitation, differentiating them from purely research-oriented developments and contributing to reducing this complexity.

Cochlear implantation has emerged as a transformative intervention in addressing profound hearing loss, offering a paradigm shift in auditory rehabilitation for individuals with restricted auditory function. Throughout its history, the understanding of contraindications for cochlear implant (CI) surgery has evolved significantly. This review comprehensively analyzes the chronological advancements in the understanding of CI contraindications, examining studies conducted from historical timelines to the present. Recent research has revealed significant developments in the field, prompting a reevaluation of established criteria and resulting in expanded indications for CI. The chronological evolution of contraindications underscores the transformative nature of the field, offering potential improvements in outcomes and enhancing the quality of life for individuals with profound hearing loss. In conclusion, this narrative review emphasizes the dynamic nature of the field, where the reevaluation of contraindications has created new opportunities and broader indications for CI. The emerging prospects, including improved outcomes and enhanced quality of life, hold promise for individuals with profound hearing loss. Full article

Objectives: Simultaneous removal and cochlear implantation (CI) have been reported in intralabyrinthine and intracochlear schwannoma. A wide range of postoperative hearing outcomes have been reported after CI in these cases. This study evaluated the outcomes of performing a simultaneous resection of Schwannoma in cochlea and cochlear implantation (CI), aiming to assess the effectiveness of this combined surgical approach for hearing rehabilitation with CI. Methods: This retrospective case series was conducted at a tertiary care center. The study included four consecutive patients with profound sensorineural hearing loss due to a mass inside the cochlea. These patients underwent simultaneous single-sided CI and tumor resection performed by the same surgeon. Preoperative and postoperative audiological assessments were conducted to evaluate the patients’ hearing outcomes before and after the surgical intervention. Results: Simultaneous CI with tumor resection was successful in all cases. Two of the four patients had a unilateral tumor, while the other two had a bilateral tumor with the involvement of the internal auditory canal and cerebellopontine angle (neurofibromatosis type 2 (NF2)). In two cases of unilateral tumor, aided free-field pure tone average (PTA) was 26 dB, and 46 dB hearing level (HL), and word recognition score (WRS) at 65 dB was 40% and 68%, respectively, 3 months after surgery. In two cases of tumor with NF2, aided free-field PTA was 36 dB and 60 dB HL, and both cases showed 0% WRS at 65 dB 3 months after surgery. Conclusions: Simultaneous schwannoma excision and CI in patients with Schwannoma inside cochlea are surgically practical and safe. Postoperatively, there was a notable improvement in hearing in cases of sporadic schwannoma, regardless of the type of CI used. However, there was 0% WRS in the two NF2 patients with a mass in the internal auditory canal. Full article
