Cochlear implant surgery can trigger a damaging tissue response inside the inner ear, and a new study suggests an anti-fibrotic drug called pirfenidone may help control it. Research from the University of Melbourne found that local delivery of pirfenidone at the time of surgery reduced tissue reaction around the implant by 40% in a guinea…
A new clinical protocol proposes a novel neuromodulation approach for tinnitus potentially linked to hidden hearing damage. Authored by Sheila Templado, the protocol describes a structured method using a non-invasive electrical stimulation device called NESA to target both the autonomic nervous system and the upper cervical spine. Key Takeaways A new protocol targets tinnitus associated…
Key Takeaways A new clinical protocol proposes a structured, non-invasive electrical neuromodulation approach targeting tinnitus linked to suspected cochlear synaptopathy. The method combines stimulation of the autonomic nervous system with targeted upper cervical nerve modulation, using a specific sequence of NESA programs. Electrode placement is distributed across the cervical spine, forehead, and sternum, moving beyond…
A potential drug treatment administered at the time of surgery reduced cochlear implant-induced tissue scarring by 40% in a preclinical study. The research, led by Kady J. Braack, Kelly L. Short, and Jorjina Plester, demonstrates that the anti-fibrotic agent pirfenidone (PFD) shows significant promise for improving long-term implant outcomes by preventing fibrosis within the cochlea….
Background conversational noise, even at moderate levels, measurably increases cognitive load and psychophysiological strain during reading. A study from Xueyi Li, Yonghong Liu, and Zihui Jiang created an interactive system, “Reading Noise,” to make this invisible strain visible in real time, offering a new way to understand how sound disrupts focus. Key Takeaways Background noise…
Key Takeaways A major review by 28 international experts clarifies how stimulation dose directly determines brain response in techniques like TMS and tDCS. Effective dosing depends on a three-part framework: the physics of the stimulus, the physiology of the tissue it reaches, and the resulting brain network changes. Individual differences in brain anatomy and physiology…
A structured, multidisciplinary protocol targeting the sensation, emotion, and cognition of tinnitus led to significant improvements in patient confidence and distress, according to a preliminary study published in *Audiology Research*. The Sensation-Emotion-Cognition (SEC) model, developed by Ali A. Danesh and colleagues, forms the core of this practical audiological framework. Key Takeaways The Sensation-Emotion-Cognition (SEC) model…
A new prognostic model for sudden sensorineural hearing loss (SSNHL) identifies systemic inflammation, immune status, blood clotting, and nutritional health as interconnected factors that can predict recovery. Published in *Scientific Reports*, the research from Shanghai Jiao Tong University School of Medicine introduces a “Commixed Index” that outperforms single blood markers in forecasting hearing outcomes. Key…
Key Takeaways Strong Familial Link: Nearly 40% of individuals with misophonia have a first-degree relative (parent, sibling, or child) who also has the condition, suggesting a significant hereditary component. High Co-Occurrence: Misophonia rarely exists alone; individuals in the study had high rates of co-occurring anxiety (70%), depression (38%), ADHD (31%), and OCD (25%). Maternal Pattern:…
Key Takeaways People with tinnitus, even with normal hearing, show measurable signs of subtle outer hair cell dysfunction, as revealed by reduced otoacoustic emissions. The study found significant weakening of the brain’s “volume control” system (the medial olivocochlear reflex) at specific frequencies in tinnitus patients. No evidence of widespread “dead regions” in the inner ear…
Key Takeaways Over half (55%) of cochlear implant users in the study reported heightened sensitivity to everyday sounds, indicating hyperacusis is a significant concern in this population. A strong link exists between hyperacusis severity and other challenges: worse sound tolerance correlated with more severe tinnitus, greater listening difficulties, and increased listening-related fatigue. 35% of participants…
Key Takeaways The Global Burden of Disease Study 2021 provides a comprehensive, global snapshot of the immense scale of hearing loss and related conditions, quantifying their impact in terms of disability and healthy years of life lost. Hearing loss remains a leading cause of disability worldwide, affecting hundreds of millions of people and contributing significantly…
