Otosclerosis

The classic history is of progressive hearing loss in a young adult. The majority will have bilateral hearing loss, but the loss is often asymmetric and sequential. About half of patients have a positive family history of otosclerosis. Tinnitus is present in two-thirds of cases.
Communication in the context of older age
Published in Rebecca Allwood, Working with Communication and Swallowing Difficulties in Older Adults, 2022
Presbyacusis refers to the normal loss of hearing that is associated with ageing. This is a sensorineural hearing loss and occurs along a spectrum of severity but can lead to complete functional bilateral hearing loss. There are multiple factors involved in the severity of the hearing loss, including genetic predisposition and amount of exposure to very loud noise.
Ageing
Published in Henry J. Woodford, Essential Geriatrics, 2022
Age-related hearing loss (presbyacusis) has more recently been termed ‘age-related sensorineural hearing impairment'. It typically affects men earlier in life than women. It tends to cause bilateral, high-frequency hearing loss of gradual onset. The prevalence of bilateral hearing loss has been found to be around 28–43% in men, and 17–20% in women aged 60 to 69 years.70 It is thought to be due to neuronal degeneration. Factors such as exposure to loud noises at work may accelerate the process.
Do all infants with congenital hearing loss meet the 1-3-6 criteria? A study of a 10-year cohort from a universal newborn hearing screening programme in Singapore

The degree of hearing loss for each infant’s individual ear was determined based on the averaged 4 frequencies (i.e. 500, 1000, 2000 and 4000 Hz) thresholds (4FA) obtained from diagnostic auditory brainstem response (ABR) assessment. Between 2000 and 2010, clinical diagnosis was based on click and tone-burst stimuli (Medelec Synergy Plinth), but results from later years were obtained using click and narrow-band CE-Chirps stimuli (Eclipse EP 25 Module). The degree of hearing loss from the better ear was used in cases of bilateral hearing loss, and from the ear with hearing loss for cases of unilateral hearing loss. The 4FA value was classified as: mild (21 to 40 dB HL), moderate (41 to 70 dB HL), severe (71 to 90 dB HL) or profound (>90 dB HL) loss. Tympanometry-1000 Hz (GSI TympStar,) results and the type of hearing loss (i.e. sensorineural, conductive, or mixed) were also recorded for individual ears.
Does the duration matter? Effect of cochlear implantation on language development in Mandarin-speaking children with hearing loss
Published in Cochlear Implants International, 2023
A total of 133 children with hearing loss, chronologically aged between 36 and 71 months, were recruited from a nonprofit organisation between 2015 and 2018. Participants had permanent bilateral hearing loss, ranging from moderate-severe to profound in the better ear (> 65 dB HL). Moreover, Mandarin was the native language of all the participants. The nonprofit organisation provided an auditory-oral intervention programme with an average enrolment age of 16.99 months (standard deviation [SD] = 11.79). The auditory-oral intervention guided children with hearing loss to use their residual hearing with the help of appropriate hearing devices (HAs or CIs) to learn to speak through listening. Auditory-oral intervention sessions ranged from once a week, twice a week, to once a month, depending on the child’s speech and language ability.
Loudness functions for patients with functional hearing loss

To assess the loudness function, the alternate binaural loudness balance (ABLB) procedure can be applied when the hearing loss is unilateral (Fritze 1980; Terkildsen and Tingsgaard 1973; Knight and Margolis 1984). Assessment of the loudness function for patients with bilateral hearing loss is usually based on loudness ratings for tones or noise bands with a range of levels (Allen, Hall, and Jeng 1990; Suzuki et al. 1995, 1996, 1999; Trevino, Jesteadt, and Neely 2016; Busby and Au 2017; Wróblewski et al. 2017; Rader et al. 2018; van Beurden et al. 2020). In our hospital (Department of Otolaryngology-Head and Neck Surgery, Tohoku University Hospital), loudness functions have been measured as a basic auditory function tests for assessing the degree of loudness recruitment, if attending doctors wish to know it.
