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.

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.

Choice Of Treatment

AbstractObjective:To compare the incidence of sensorineural hearing loss between those treated with docetaxel, cisplatin and 5-fluorouracil induction chemotherapy followed by carboplatin concurrent chemoradiotherapy and those treated with conventional concurrent chemoradiotherapy for advanced nasopharyngeal carcinoma.Methods:Serial pure tone audiometry was conducted in 36 nasopharyngeal carcinoma patients who were randomised into 2 groups. The first group received docetaxel, cisplatin and 5-fluorouracil induction chemotherapy followed by carboplatin concurrent chemoradiotherapy. The second group received conventional concurrent chemoradiotherapy.Results:The incidence of sensorineural hearing loss at speech frequency in the first group was 10 per cent and in the second group was 50 per cent (p = 0.0027). Bone conduction thresholds were significantly increased after completion of the treatment at 2–4 kHz in the first group and at all frequencies in the second group.Conclusion:The docetaxel, cisplatin and 5-fluorouracil induction chemotherapy regimen followed by concurrent chemoradiotherapy was associated with a lower incidence of sensorineural hearing loss than conventional concurrent chemoradiotherapy. This regimen may be the preferred choice of treatment for hearing preservation.

AbstractA prospective study of hearing loss in 120 cases with non-explosive blast injury of the ear, gathered over a six-year period, is presented. Thirty-three (27.5 per cent) patients had normal hearing, 57 (47.5 per cent) conductive hearing loss, 29 (24.2 per cent) mixed loss and one (0.8 per cent) had pure sensorineural loss. The severity of conductive hearing loss correlated with the size of the eardrum perforation; only a marginal difference was found between water and air pressure injuries, with respect to this type of hearing loss. Of all locations, perforations involving the posterior-inferior quadrant of the eardrum were associated with the largest air-bone gap. Audiometric assessment revealed that none of the patients suffered ossicular chain damage. Three patterns of sensorineural hearing loss were identified: a dip at a single frequency, two separate dips, and abnormality of bone conduction in several adjacent high frequencies. Involvement of several frequencies was associated with a more severe hearing loss than a dip in a single frequency. Healing of the perforation was always accompanied by closure of the air-bone gap, while the recovery of the sensorineural hearing loss was less favourable.

Cochlear Damage

The author's series of 3000 consecutive operations of tympanoplasty from 1960 to 1975 were reviewed in regard to the occurrence of sensorineural hearing loss as a consequence of the surgical procedure. Worsening of bone conduction thresholds by 10 dB through the frequencies 500 to 4000 cps, or a 10% reduction in speech discrimination scores were considered significant. Whereas in transcanal tympanoplasty the incidence of cochlear damage was greater in ears when initially the ossicular chain was incomplete, by contrast in combined approach tympanoplasty the risk was greater when the chain was intact initially. It was concluded that cochlear trauma was usually due to 1) the hydraulic effect of excessive stapes manipulation during the removal of disease, and 2) the development of a perilymph fistula. The unpredictable predisposing threat of cochlear fragility due to genetic and inflammatory factors was emphasized and the poor results of tympanoplasty in tympanosclerosis were underlined. The current methods of treating sensorineural hearing loss after tympanoplasty were enumerated and discussed. It was concluded that although those aimed at improving labyrinthine circulation had theoretical backing, there is as yet little experimental or clinical evidence to support the claims of their protagonists.
