Sensory Neural Hearing Loss

A 10-year-old girl whose bilateral, low-frequency, sensory-neural hearing loss had been noted three years earlier showed a drop in speech discrimination in her left ear with no corresponding decrease in pure-tone sensitivity. Psychoacoustic tuning curves and middle-component averaged electroencephalic responses to tone-pips suggested that damage to the left ear had become greater than indicated by the pure-tone audiogram, accounting for the drop in speech discrimination. This case suggests caution in inferring the magnitude of damage to the peripheral auditory system from tonal thresholds.

Method Of Constant Stimuli

The method of limits and the method of constant stimuli were employed to investigate test-retest consistency in behavioral auditory responsivity within 18 normal hearing subjects, 18 subjects with sensory-neural hearing loss and 18 subjects with non-organic hearing loss. A 1 000 cps pure-tone stimulus was used for all measurements. Findings suggest that: (1) individuals with non-organic hearing loss are as consistent as normal hearing subjects and subjects with sensory-neural hearing loss when reproducing pure-tone thresholds measured at 1 000 cps by identical psychophysical methods; (2) response patterns obtained with two procedures utilizing the method of constant stimuli clearly differentiate the performance of subjects with non-organic hearing loss from that of normal hearing subjects and subjects with sensory-neural hearing loss, while the response patterns produced by normal hearing subjects are practically identical to those produced by subjects with sensory-neural hearing loss; (3) “shock threat” included in one procedure employing the method of constant stimuli failed to significantly affect responsivity patterns within either of the three groups.

Sensory Neural Hearing Loss

Introduction Incidence of sensory neural hearing loss following mastoid surgery varies from 1.2 – 4.5%.There are various causes for postoperative sensorineural hearing loss during mastoid surgery. This study aims to identify whether there is any correlation between drilling and postoperative sensory neural hearing loss. MethodsA retrospective study was conducted in the Department of ENT from January 2018 to June 2019. A total number of 68 patients above five years of age who underwent modified radical mastoidectomy for chronic otitis media squamous were included. Revision surgery, preoperative sensorineural hearing loss, injury to the ossicular chain during surgery, patients with lack of follow up or doubtful reports in mentally challenged were excluded from the study. The average bone conduction threshold was calculated from 500, 1000, 2000, 4000 Hz and compared using the Wilcoxon signed-rank test. ResultsThere were 43 males and 25 females in the study with a median age of 23.5 years (16-55). The mean preoperative bone conduction threshold in the four frequencies of 500 Hz, 1kHz, 2kHz, 4kHz were -2.06dB, -2.06dB, 3.31dB, 4.63 dB respectively and the mean postoperative bone conduction thresholds were 1.03, 1.32, 5.29, 4.04 respectively. There was a decline of mean of 3.09 dB and 3.38dB only at the low-frequencies (500Hz and 1kHz) BC threshold respectively which were statistically significant, whereas at higher frequency there was no decline in average postoperative BC threshold. ConclusionThere is no definite role of drill in inducing hearing loss and if present other causes of hearing loss should be sought in postoperative sensorineural hearing loss.

Spatial Release

Purpose Type 2 diabetes mellitus (DM2) is associated with impaired hearing. However, the evidence is less clear if DM2 can lead to difficulty understanding speech in complex acoustic environments, independently of age and hearing loss effects. The purpose of this study was to estimate the magnitude of DM2-related effects on speech understanding in the presence of competing speech after adjusting for age and hearing. Method A cross-sectional study design was used to investigate the relationship between DM2 and speech understanding in 190 Veterans ( M age = 47 years, range: 25–76). Participants were classified as having no diabetes ( n = 74), prediabetes ( n = 19), or DM2 that was well controlled ( n = 24) or poorly controlled ( n = 73). A test of spatial release from masking (SRM) was presented in a virtual acoustical simulation over insert earphones with multiple talkers using sentences from the coordinate response measure corpus to determine the target-to-masker ratio (TMR) required for 50% correct identification of target speech. A linear mixed model of the TMR results was used to estimate SRM and separate effects of diabetes group, age, and low-frequency pure-tone average (PTA-low) and high-frequency pure-tone average. A separate model estimated the effects of DM2 on PTA-low. Results After adjusting for hearing and age, diabetes-related effects remained among those whose DM2 was well controlled, showing an SRM loss of approximately 0.5 dB. Results also showed effects of hearing loss and age, consistent with the literature on people without DM2. Low-frequency hearing loss was greater among those with DM2. Conclusions In a large cohort of Veterans, low-frequency hearing loss and older age negatively impact speech understanding. Compared with nondiabetics, individuals with controlled DM2 have additional auditory deficits beyond those associated with hearing loss or aging. These results provide a potential explanation for why individuals who have diabetes and/or are older often report difficulty understanding speech in real-world listening environments.

Sensory Neural Hearing Loss

In patients who are thought to have a perilymph (PL) fistula, careful inspection of the round and oval windows during exploratory tympanotomy may be normal. The decision must then be made either to terminate the procedure—knowing that the patient's symptoms will probably continue or deteriorate—or to repair both windows as if PL fistulas were present, risking further damage to the inner ear. From a series of 14 patients explored for possible PL fistulas, we report on 6 patients with preoperative diagnoses of PL fistula, based on history, physical examination, and audiometry. Symptoms resulting from trauma were present from 10 days to 23 years before surgery. During exploratory tympanotomy, no fistulas were evident; however, both the oval and round windows were repaired with tissue grafts. Follow up—for 1 to 5 years—revealed that vertigo was relieved in all patients. Postoperatively, one patient had a mild conductive hearing loss; yet no patient sustained a sensory neural hearing loss. We conclude that patch grafting of both the oval and round windows is a safe and effective method of treating suspected, but inapparent fistulas. Patient selection, surgical technique, and results shall be detailed.

Objectives: To correlate the hearing loss with duration of the disease, stage of the disease, ototoxic drugs use, co-morbidity and biochemical parameters in patients with chronic kidney disease (CKD).Material and Methods: This prospective study of 50 CKD patients was conducted in the department of ototolaryngology head and neck surgery and department of internal medicine, B. P. Koirala Institute of Health Sciences, Dharan, between December 2008 to November 2009. The blood investigation report of the patients were noted. Otological examination was carried out including tunning fork test and pure tone audiometry. Middle ear pathology and conductive hearing loss were excluded. Data was collected and analyzed.Results : Sensory neural hearing loss was higher in patients with; end stage renal disease (stage-5), co-morbidity, haemoglobin level less than 8.5, duration of CKD greater than 2 years, and ototoxic drug administration, but not statistically significant (P-value >0.05). Hearing loss in patients with CKD was not influenced by fasting blood sugar, serum urea, creatinine, sodium, potassium, calcium and serum phosphorus. (P-value >0.05)Conclusion: The hearing loss in patients with chronic kidney disease was not significantly related with stage of CKD, co-morbidity, ototoxic drug use, fasting blood sugar, serum urea, creatinine, sodium, potassium, calcium and serum phosphorus (P-value >0.05). The sensory neural hearing loss in these patients may be due to the advanced age and possible accelerated presbyacusis by the disease.
