Brain Injured

This study investigated the effects of congenital brain injury alone, or in combination with sensori-neural hearing loss, upon figure-ground thresholds for spondees in young children. Forty-eight subjects were selected from four diagnostic categories: (1) brain injured, normally hearing; (2) brain-injured, hearing-handicapped, (3) non-brain-injured, normally hearing; and (4) non-brain-injured, hearing-handicapped. Brain-injured and non-brain-injured subjects were matched for pure-tone thresholds. Selected spondees were presented bilaterally, first in quiet then in a background of white noise. Results indicated no effect upon speech thresholds by brain injury, and no apparent interaction between brain injury and hearing impairment.

High Pass

The limitations of noisemakers and speech in detecting marked high-frequency hearing impairment in young children are illustrated by special analysis. The use of high-pass filtering of noisemakers and speech at 6000 Hz and above is recommended as one practical means of identifying losses of this type in children too young for voluntary pure-tone testing.

The study provides an analysis of medical and psychological and pedagogical assistance to children with hearing impairment at an early age in St. Petersburg in accordance with the modern standard «1-3-6». It was found that only 19% of children with hearing impairment registered at the Audiology Center were diagnosed with hearing loss before the age of 3 months, at the age of 6 months. 5,4% of children had hearing aids. A model for the development of a system of comprehensive care for young children with hearing impairment in St. Petersburg has been developed. The model includes 5 stages, for each of which a system of organizational measures is presented, aimed at improving the effectiveness of comprehensive care using a family-centered approach. The implementation of the model made it possible to increase the proportion of children diagnosed before the age of 3 months and to reduce the average age of hearing aid in young children. Expansion of the range of services in the Audiology Center (a course of classes on adapting a child to hearing aids during primary hearing aids, group deaf pedagogical and musical classes with children and parents, a school for parents, parental counseling by a psychologist), as well as the introduction of remote forms of support contributed to an increase in the competence of parents in matters of hearing aids, development of infant with hearing loss and parental activity in the classroom with the child. Remote forms of work made it possible to continue the rehabilitation of children during the COVID-19 pandemic. The developed model for the development of comprehensive care for young children with hearing impairment and their families may be useful for other regions of the Russian Federation.

Using the Hearing Handicap Inventory for Adults (HHIA), we assessed self-perceived hearing handicap in a sample of 63 patients having either unilaterally normal hearing or a mild hearing loss (pure tone average ≤40 dB hearing level). Large intersubject variability in responses to the HHIA confirmed observations that reactions to minimal hearing impairment vary greatly among patients. The individual differences in responses highlight the importance of quantifying the perceived communication and psychosocial handicap, which cannot be determined from the audiogram alone. An item examination of responses to the HHIA revealed a number of emotional and social-situational problems encountered by patients with minimal hearing loss.

Although several reports exist concerning the occurrence of hearing loss in patients withdisorders of thyroid function, there are still several unsettled issues, such as theincidence and the severity of hearing impairment, the anatomic site of the auditorypathway involved, and the possible pathogenetic mechanisms. Both congenitalhypothyroidism and environmentally based iodine deficiency are established causes ofhearing loss in humans and rodents. Congenital thyroid deficiency in humans can resultin a profound, hearing deficit, which may be prevented by early hormonal replacementtreatment in infants with hypothyroidism. However, the effect of acute or chronichypothyroidism in adults has not been adequately studied, and most information hasbeen obtained from animal experiments, whereas research in humans has been basicallybased on behavioral audiometry. The use of otoacoustic emissions may provide moreinsight into the hearing function of these patients than pure-tone audiometry, since it isconsidered as a sensitive test of the cochlear status. The aim of this study was toevaluate the hearing in a group of patients with acute hypothyroidism, using bothconventional audiometry and transiently evoked otoacoustic emissions (TEOAEs). Material and methods:A group of 52 patients with thyroid carcinoma who underwent total thyroidectomy wasstudied prospectively, All patients were examined before surgery and 6-8 weekspostoperatively. During this period there was no replacement with levothyroxine and themagnitude of thyroxin depletion was monitored by serum thyroid-stimulating hormone levels. On preoperative encounter with each patient, a detailed questionnaire of historyof hearing loss, tinnitus, vertigo, previous ear infections, noise exposure, medications,and recent upper respiratory tract infection was completed. Patients were excluded ifthey were older than 50 years, in order to avoid the phenomenon of presbycusis, or ifthey had a history of cochleovestibular, vascular or neurologic disease, or any other riskfactor for hearing impairment. Pure-tone audiometry, tympanometry and transientlyevoked otoacoustic emissions were performed. A group of healthy volunteers of similarage and sex were used for comparison.Results:(1) Tympanograms were normal, either on initial testing (75%) or on repeat testing(25%).(2) Audiometry showed elevation of all postoperative hearing thresholds, whereas thethresholds varied significantly across frequency.(3) TEOAE testing showed response signal to noise ratios lower in the postoperativesession (hypothyroid state) than in the preoperative session on all measured frequencies.(4) Emission levels varied significantly across frequency, with maximum responseobserved at 2 kHz.(5) Comparison of significant pure-tone and otoacoustic emission shifts for individualears showed more ears affected in otoacoustic emission testing, indicating subclinicalcochlear involvement.(6) Comparison of hearing thresholds and otoacoustic emission levels between patientsand controls showed significant differences on postoperative testing. Conclusions:Acute hypothyroidism in adults causes elevation of hearing thresholds and reducedotoacoustic emissions. The effect on otoacoustic emissions is greater, indicatingsubclinical damage of the cochlear function.

Objective To investigate the association of midlife hypertension with late-life hearing impairment. Study Design Data from the Atherosclerosis Risk in Communities study, an ongoing prospective longitudinal population-based study (baseline, 1987-1989). Setting Washington County, Maryland, research field site. Subjects and Methods Subjects included 248 community-dwelling men and women aged 67 to 89 years in 2013. Systolic blood pressure (SBP) and diastolic blood pressure were measured at each of 5 study visits from 1987-1989 to 2013. Hypertension was defined by elevated systolic or diastolic blood pressure or antihypertensive medication use. A 4-frequency (0.5-4 kHz) better-hearing ear pure tone average in decibels hearing loss (dB HL) was calculated from pure tone audiometry measured in 2013. A cutoff of 40 dB HL was used to indicate clinically significant moderate to severe hearing impairment. Hearing thresholds at 5 frequencies (0.5-8 kHz) were also considered separately. Results Forty-seven participants (19%) had hypertension at baseline (1987-1989), as opposed to 183 (74%) in 2013. The SBP association with late-life pure tone average differed by the time of measurement, with SBP measured at earlier visits associated with poorer hearing; the difference in pure tone average per 10–mm Hg SBP measured was 1.43 dB HL (95% CI, 0.32-2.53) at baseline versus −0.43 dB HL (95% CI, −1.41 to 0.55) in 2013. Baseline hypertension was associated with higher thresholds (poorer hearing) at 4 frequencies (1, 2, 4, 8 kHz). Conclusion Midlife SBP was associated with poorer hearing measured 25 years later. Further analysis into the longitudinal relationship between hypertension and hearing impairment is warranted.

AbstractThere have been numerous recent reports on the association between hearing impairment and cognitive function, such that the cognition of adults with hearing loss is poorer relative to the cognition of adults with normal hearing (NH), even when amplification is used. However, it is not clear the extent to which this is testing artifact due to the individual with hearing loss being unable to accurately hear the test stimuli.The primary purpose of this study was to examine whether use of amplification during cognitive screening with the Montreal Cognitive Assessment (MoCA) improves performance on the MoCA. Secondarily, we investigated the effects of hearing ability on MoCA performance, by comparing the performance of individuals with and without hearing impairment.Participants were 42 individuals with hearing impairment and 19 individuals with NH. Of the individuals with hearing impairment, 22 routinely used hearing aids; 20 did not use hearing aids.Following a written informec consent process, all participants completed pure tone audiometry, speech testing in quiet (Maryland consonant-nucleus-consonant [CNC] words) and in noise (Quick Speech in Noise [QuickSIN] test), and the MoCA. The speech testing and MoCA were completed twice. Individuals with hearing impairment completed testing once unaided and once with amplification, whereas individuals with NH completed unaided testing twice.The individuals with hearing impairment performed significantly less well on the MoCA than those without hearing impairment for unaided testing, and the use of amplification did not significantly change performance. This is despite the finding that amplification significantly improved the performance of the hearing aid users on the measures of speech in quiet and speech in noise. Furthermore, there were strong correlations between MoCA score and the four frequency pure tone average, Maryland CNC score and QuickSIN, which remain moderate to strong when the analyses were adjusted for age.It is concluded that the individuals with hearing loss here performed less well on the MoCA than individuals with NH and that the use of amplification did not compensate for this performance deficit. Nonetheless, this should not be taken to suggest the use of amplification during testing is unnecessary because it might be that other unmeasured factors, such as effort required to perform or fatigue, were decreased with the use of amplification.

Theoretical interpretations and terminological practices can interfere with appropriate clinical management of hearing losses in children with language disorders. De-emphasis of the significance of hearing losses for pure tones in children who present problems in language development is unwarranted. The value of the pure-tone result in determining the nature and severity of hearing impairment is well established. The child with a hearing loss for pure tones must be given the benefit of whatever amplification and educational placement considerations are indicated by his loss, regardless of the diagnostic classifications or speculations evoked by other problems he may present.

Acoustic reflex thresholds for pure tones and white noise were used to predict severity of audiometric loss in 1043 ears with sensorineural hearing loss. Both severity and slope of loss were predicted in an additional 113 ears. Prediction was usually quite accurate. Serious errors occurred in only 4% of cases. These findings have important implications for the auditory evaluation of babies and young children.

Abstract OBJECTIVE The nerve function of Cranial Nerve VIII is at risk during microvascular decompression for hemifacial spasm. Intraoperative monitoring of brainstem auditory evoked potentials (BAEPs) can be a useful tool to decrease the danger of hearing loss. The aim of this study was 1) to assess the side effects of surgery on hearing and describe the main intraoperative BAEP changes observed in the authors' series, and 2) to define warning values beyond which the probability of hearing impairment rises significantly. These values were calculated by correlating the (possible) postoperative hearing disturbances evaluated in terms of pure tone average with intraoperative BAEP changes (especially delay in Wave V latency). METHODS This series included 84 consecutive patients affected with hemifacial spasm who underwent microvascular decompression during which BAEPs were monitored. During surgery, Wave I, I to V interpeak interval, latency, and amplitude of Wave V were recorded and measured. Auditory function was studied before and after surgery and expressed as a pure tone average in all patients. Then, correlations were made between hearing impairment after surgery and intraoperative BAEP changes in an attempt to define warning values. RESULTS Seventy-four patients (88%) had no hearing loss after surgery (Group 1). Eight patients (9.5%) had hearing impairment with a decrease in pure tone average of more than 20 dB (Group 2). Two patients (2.3%) experienced a definitive and complete hearing loss on the side operated on (Group 3). Among intraoperative BAEP changes, latency of Peak V was the most frequently observed and the most significant phenomenon, especially during cerebellar retraction and the decompression step of the microvascular decompression procedure. In the group of patients without hearing loss (Group 1), the mean delay in latency of Peak V was 0.61 millisecond (standard deviation, ±0.36 ms); in the group with hearing decrease (Group 2), the mean delay was 1.05 milliseconds (standard deviation, ±0.64 ms); and in the group with deafness (Group 3), Wave V was abolished. CONCLUSION From a practical standpoint, three warning values, based on delay in latency of Peak V, were established for use during surgery: an initial one at 0.4 millisecond (“watching” signal) at the safety limit; a second one at 0.6 millisecond (risk “warning” signal), which is the mean value corresponding to the group of patients without postoperative hearing loss; and an ultimate one at 1 millisecond (“critical” warning), before irreversibility. These warnings should help the surgeon to avoid or correct maneuvers that are dangerous for hearing function, which is mandatory in functional surgery.
