Recent interesting papers with free full text links:
- Towards a unified testing framework for single-sided deafness studies: A consensus paper. (Van de Heyning, 2016). Full text: https://www.karger.com/Article/FullText/455058
International consensus statement recommending minimum outcome measures for SSD management (CROS-HA, BC devices, and CI treatment) as (1) speech in noise testing comparing binaural benefits such as summation, squelch, and head shadow (2) localization testing (3) questionnaires to collect quality of life measures and the frequency of device use; and (4) questionnaires for assessing the impact of tinnitus before and after treatment, if applicable.
- Cochlear neuropathy in human presbycusis: confocal analysis of hidden hearing loss in post-mortem tissue. (Viana et al, 2015). Full text: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4554812/
Recent animal work has suggested that cochlear synapses are more vulnerable than hair cells in both noise-induced and age-related hearing loss. The condition results in perfectly normal audiogram but difficulty in speech perception hence the term ‘hidden hearing loss’. Furthermore, even after noise exposures causing only transient threshold elevation and no hair cell loss, there can be immediate and irreversible loss of 40–50% of the cochlear nerve synapses on inner hair cells. Type ‘Cochlear Synaptopathy’ in Pubmed for more recent work on diagnosis of ‘hidden hearing loss’.
- Auditory neuropathy–neural and synaptic mechanisms. (Moser and Starr, 2016) http://escholarship.org/uc/item/934824jw
Review article brilliantly explaining the current thinking around the pathophysiology of auditory neuropathy spectrum disorder. This, of course, has repercussion on choice of management options for ANSD.
