Hearing Thresholds

Two experiments were performed for this study. The purpose of both experiments was to examine the validity of pure-tone hearing thresholds obtained near the rising portion of a sensorineural hearing loss. Recent work by other investigators has suggested that thresholds obtained near the rising portion of the audiogram may not correspond to the severity of damage at the cochlear place associated with the test frequency. In the first experiment this issue was addressed in 11 subjects having low frequency sensorineural hearing loss, whereas 12 subjects (19 ears) having notch-shaped high-frequency sensorineural hearing losses were examined in the second experiment. The results indicated that thresholds obtained from the rising portion of the audiometric configuration were, in most instances, determined by sensitivity at the test frequency. An exception to this generalization involved low-frequency sensorineural hearing loss with a slope for the rising portion of the audiogram exceeding -25 dB/octave. In these cases the severity of the loss may be underestimated for test frequencies immediately adjacent to the rising portion of the audiogram.

Post Traumatic

Post-traumatic pneumolabyrinth is an uncommon clinical entity, particularly in the absence of temporal bone fracture. We report the case of a patient who presented to our emergency department with a headache, sudden left hearing loss and severe dizziness which began after a traumatic brain injury 3 days earlier. On examination, the patient presented signs of left vestibulopathy, left sensorineural hearing loss and positive fistula test, normal otoscopy and without focal neurological signs. The audiometry confirmed profound left sensorineural hearing loss. Cranial CT revealed a right occipital bone fracture and left frontal subdural haematoma, without signs of temporal bone fracture. Temporal bone high-resolution CT scan revealed left pneumolabyrinth affecting the vestibule and cochlea. Exploratory tympanotomy revealed perilymphatic fistula at the location of the round window. The sealing of defect was performed using lobule fat and fibrin glue. He presented complete resolution of the vestibular complaints, though the hearing thresholds remained stable.

Compressed Speech

This study explored whether the time-compressed speech perception varied with the degree of hearing loss in high-frequency sensorineural hearing loss (HF SNHL) individuals. 65 HF SNHL individuals with different cutoff frequencies were recruited and further divided into mildly, moderately, and/or severely affected subgroups in terms of the averaged thresholds of all frequencies exhibiting hearing loss. Time-compressed speech recognition scores under both quiet and noisy conditions and gap detection thresholds within low frequencies that had normal thresholds were obtained from all patients and compared with data from 11 age-matched individuals with normal hearing threshold at all frequencies. Correlations of the time-compressed speech recognition scores with the extents of HF SNHL and with the 1 kHz gap detection thresholds were studied across all participants. We found that the time-compressed speech recognition scores were significantly affected by and correlated with the extents of HF SNHL. The time-compressed speech recognition scores also correlated with the 1 kHz gap detection thresholds except when the compression ratio of speech was 0.8 under quiet condition. Above all, the extents of HF SNHL were significantly correlated with the 1 kHz gap thresholds.

Significant Difference

Recent studies have identified sensorineural hearing loss as a possible manifestation of ankylosing spondylitis. We conducted a study of 30 patients with ankylosing spondylitis to characterize their audiologic profile and to correlate their disease activity and functional indices with their hearing thresholds. The study group was made up of 18 men and 12 women, aged 25 to 58 years (mean: 46.5), who were diagnosed with ankylosing spondylitis. We compared their findings with a socially and demographically matched group of 30 healthy controls. All 60 participants underwent an audiologic assessment, consisting of pure-tone audiometry, speech audiometry, and tympanometry. We used validated indices to assess disease activity and functional status, and we compiled information on the time of diagnosis and the types of medications used to treat the ankylosing spondylitis. We found that the average of the mean air-conduction thresholds at 0.5, 1, 2, and 4 kHz in the ankylosing spondylitis group was significantly worse than that of the controls (p = 0.004). A statistically significant difference was observed at frequencies greater than 3 kHz (p < 0.05). A subgroup of case patients who used only a tumor necrosis factor-alpha inhibitor exhibited better hearing thresholds than patients who used other drugs (p = 0.01). Differences in functional and disease activity scores between case patients with and without hearing loss were not statistically significant. We found that patients with ankylosing spondylitis did indeed have a greater prevalence of sensorineural hearing loss but that it was not correlated with either disease activity or functional status.

The Common

The present report describes three familial cases of recessive hearing loss associated with enlargement of the vestibular aqueduct (EVA). Six siblings from three families showed EVA. The common characteristic of these patients was the presence of congenital, high-frequency, fluctuating sensorineural hearing loss. These cases suggest that EVA may be a useful discriminator between different types of recessive hearing loss.

Objective To describe the progression of sensorineural hearing loss (SNHL) in the better- and poorer-hearing ears in children with asymptomatic congenital cytomegalovirus (CMV) infection with isolated SNHL. Study Design Longitudinal prospective cohort study. Setting Tertiary medical center. Subjects and Methods We analyzed hearing thresholds of the better- and poorer-hearing ears of 16 CMV-infected patients with isolated congenital/early-onset or delayed-onset SNHL identified through hospital-based CMV screening of >30,000 newborns from 1982 to 1992. Results By 12 months of age, 4 of 7 patients with congenital/early-onset SNHL developed worsening thresholds in the poorer-hearing ear, and 1 had an improvement in the better-hearing ear. By 18 years of age, all 7 patients had worsening thresholds in the poorer-hearing ear and 3 patients had worsening thresholds in the better-hearing ear. Hearing loss first worsened at a mean age of 2 and 6 years in the poorer- and better-hearing ears, respectively. Nine patients were diagnosed with delayed-onset SNHL (mean age of 9 years vs 12 years for the poorer- and better-hearing ears), 6 of whom had worsening thresholds in the poorer-hearing ear and 1 in both ears. Conclusion In most children with congenital CMV infection and isolated SNHL, the poorer-hearing ear worsened earlier and more precipitously than the better-hearing ear. This study suggests that monitoring individual hearing thresholds in both ears is important for appropriate interventions and future evaluation of efficacy of antiviral treatment.
