Objective: To evaluate the feasibility and value of integrated methods to assess auditory pathway integrity.
Method: Twenty-four cases of bilateral profoundly-deafened individuals who were considered as the candidates of cochlear implantation were included in this study. Auditory pathway integrity from these candidates of cochlear implantation were assessed with the integrated methods established by our team, which consist of 5 categories including 1. audiological test; 2. radiological imaging study; 3. ear-canal electric audiometry; 4. response to sound in daily life; and 5. speech development.
Result: Twenty-three candidates who meet the criteria of auditory nerve-auditory pathway integrity received cochlear implantation with improved hearing and speech development postoperatively. The remainder one of the 24 candidates was diagnosed as bilateral absence of auditory nerve. The fault of cochlear implantation was avoided.
Conclusion: The integrated methods for assessing auditory pathway integrity is feasible and valuable. Auditory nerve-auditory pathway integrity should be considered and included as one of the most important criteria for cochlear implantation candidate.

Reversing Cochlear Nucleus Maladaptive Plasticity via Customized Extracochlear Stimulation: A New Approach for Tinnitus Treatment.
Adv Sci (Weinh)

ENT Institute and Department of Otolaryngology, Eye & ENT Hospital of Fudan University, Shanghai, 200031, China.
Tinnitus, a widespread condition affecting numerous individuals worldwide, remains a significant challenge due to limited effective therapeutic interventions. Intriguingly, patients using cochlear implants (CIs) have reported significant relief from tinnitus symptoms, although the underlying mechanisms remain unclear and intracochlear implantation risks cochlear damage and hearing loss. This study demonstrates that targeted intracochlear electrical stimulation (ES) in guinea pigs with noise-induced hearing loss reversed tinnitus-related maladaptive plasticity in the cochlear nucleus (CN), characterized by reduced auditory innervation, increased somatosensory innervation, and diminished inhibitory neural networks.
View Article and Find Full Text PDFIntroduction: This study aims to investigate the impact of auditory input on postural control in young adult cochlear implant users with profound sensorineural hearing loss. The research explores the relationship between auditory cues and static postural stability in individuals with hearing impairment.
Methods: 34 young adult cochlear implant users, consisting of 15 males and 19 females aged 18-35 years, underwent various balance tests, including the modified Clinical Tests of Sensory Interaction on Balance (mCTSIB) and the Unilateral Stance Test (UST), under different auditory conditions: (1) White noise stimulus present with the sound processor activated, (2) Ambient noise present with the sound processor activated, and (3) Sound processor deactivated.

Background: The aim of this study was to relate response patterns of electrocochleography (ECochG) recordings during cochlear implantation to pre- and postoperative hearing.
Methods: Thirty subjects with either flat (FA, n = 9) or sloping (SA, n = 21) audiograms before cochlear implantation were prospectively included. Real-time ECochG recordings were conducted via the cochlear implant.
