Abstract Introduction Patients with vestibular schwannomas (VS) must have formal audiology during their workup, according to multiple national guidelines (including NICE). Method This retrospective study sought to audit the percentage of VS cases undergoing formal audiometry at a tertiary neurosurgical centre. An illustrative sample was selected randomly from local databases (2006-2019). Data collected included audiometry types (speech discrimination [SD], pure tone audiometry [PTA]), management pathway (surgery, radiotherapy or conservative) and symptom profile. Results 200 cases were assessed, 7 were excluded (private patients, patients referred but not formally seen). Of the 193 cases included, 186 (96.4%) had ≥1 Pure Tone assessment [PTA], with 135 (70%) also tested on Speech Discrimination [SD]. The surgical cohort had the highest audiometry rates at 38/38, followed by 116/121 (96%) for surveillance and 32/34 (94%) for radiotherapy subgroups. Reasons for no audiology were: profound hearing loss at presentation (2/7), audiometry at local centres (4/7) and patient compliance (1/7). Conclusions Our service is highly compliant (96.4%), consistent across management categories. The rate of SD (70%), a functional measure of hearing impairment, can be improved. Monitoring surgical outcomes via formal audiometry should be standard, particularly surgical approaches that preserve hearing are chosen. Follow-up audiometry regimes can be standardized for those on surveillance pathways.

Background: Patients with hearing disturbance will generally undergo pure tone audiometry andspeech audiometry in a quiet room, but those examinations cannot evaluate the ability to understand speech in daily environment with a noisy background. Words in noise test will provide valuable informationregarding patient’s hearing problem in noise. Purpose: To evaluate the hearing threshold using wordsin noise test in adults with normal hearing. Method: This cross-sectional study was conducted in CiptoMangunkusumo Hospital from January to April 2017. All subjects who fulfilled the inclusion and exclusioncriteria underwent pure tone audiometry, speech audiometry, and words in noise test. Results: A total of71 individuals with normal hearing were recruited for this study. Words in noise test showed the medianvalue of 67 dB and 100 dB for Speech Recognition Threshold (SRT) 50% and Speech DiscriminationScore (SDS) 100%, respectively. The SRT 50% and SDS 100% were significantly higher in the age group40–60 years compared to the age group 18–39 years. There was also a statistically significant differencebetween males and females at SRT 50% assessed by words in noise audiometry. Conclusion: Wordsin noise test showed a statistically significant difference in SRT 50% and SDS 100% between two agegroups, but no difference was found between genders. The result of this study can be used as a referencefor SRT and SDS values of speech audiometry test in noise.Keywords: words in noise, speech audiometry, speech recognition threshold, speech discrimination score ABSTRAKLatar belakang: Pasien dengan gangguan pendengaran umumnya menjalani pemeriksaanaudiometri nada murni dan audiometri tutur di ruangan yang sunyi, tetapi pemeriksaan ini tidakdapat menggambarkan kemampuan pemahaman wicara di lingkungan sehari-hari yang ramai.

The long-term effects of H. influenzae meningitis were studied in 86 patients who were treated with acceptable antibiotic therapy during acute episode in 1950 to 1964 in Nashville, Tennessee. Follow-up revealed that 11 were dead (eight died within first 24 hours of hospitalization). Fifty-six of them returned to Vanderbilt Medical Center for the following appraisals: history, general physical and neurological examinations; pure tone audiometry evaluation; and psychological testing by Wechsler Intelligence Scale for Children. Nineteen others sent information by questionnaire. Results indicated that 26 (29%) survivors had severe or significant handicaps; 12 (14%) had possible residuals; and 37 (43%) were free of detectable deficits. It was concluded that prevention of this disease should now be a prime goal.

AbstractBACKGROUNDThe middle cranial fossa (MCF) approach is a challenging surgical technique for the resection of small and intermediate sized, primarily intracanalicular, vestibular schwannomas (VS), with the goal of hearing preservation (HP).OBJECTIVETo describe a decade-long, single institutional experience with the MCF approach for resection of VS.METHODSThis is a retrospective cohort study of 63 patients who underwent the MCF approach for resection of VS from 2006 to 2016. Audiometric data included pure-tone average (PTA), low-tone pure-tone average (LtPTA), word recognition score, and American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) hearing classification at presentation and follow-up. Patients with postoperative serviceable (AAO-HNS class A-B) and/or useful (AAO-HNS class A-C) hearing were compared to those without HP. Facial nerve function was assessed using the House–Brackmann scale.RESULTSThe mean age and duration of follow-up were 50 ± 13 yr and 21 ± 21 mo, respectively. The mean tumor size was 10 ± 4 mm. The serviceable and usable HP rates were 54% and 50%, respectively. Some residual hearing was preserved in 71% of patients. Large tumor size (P = .05), volume (P = .03), and extrameatal tumor extension (P = .03) were associated with poor audiometric outcomes. The presence of a fundal fluid cap (P = .01) was a favorable finding. At definitive testing, LtPTA was significantly better preserved than traditional PTA (P = .01). Facial nerve outcomes, tumor control rates, and durability of audiometric outcomes were excellent. 47% of patients pursued aural rehabilitation.CONCLUSIONIn our series, the MCF approach for VS provided excellent rates of tumor and facial nerve function, with durable serviceable HP.

Abstract Twenty-six patients with secondary or early latent sypilis were examined by auditory brainstem reponse (ABR) audiometry and by pure tone audiometry before and after treatment. Normalization was registered in four of seven patients with pathological ABR before treatment, while in three patients the ABR abnormalities remained after treatment. Thirteen patients exhibited a sensorineural hearing-loss before treatment. In two patients this hearing-loss improved after treatment and a syphilitic etiology seems plausible. The reversible lesions in the auditory system may be related to asymptomatic syphilitic meningitis. Permanent ABR abnormalities might reflect syphilitic vascular involvement in the brainstem.

BACKGROUND Radiotherapy is a very well-known treatment modality for head and neck cancers besides surgery. The cochlea and its neuroepithelium are sensitive to ionizing radiation and resultant damage as it remains in the field of irradiation, the chemotherapy also has a similar effect leading to sensorineural hearing loss (SNHL). To minimize the adverse effects of hearing the advent of technology like intensitymodulated radiotherapy (IMRT) using smaller doses of radiation is now available with good control of the disease. The intended concomitant uses of chemotherapeutic agent cisplatin for increasing the sensitivity of radiation may induce ototoxicity. Both of these modalities result in a pronounced effect on highfrequency sensorineural hearing loss. We wanted to determine and compare sensorineural hearing loss amongst cases of head and neck cancer treated by radiotherapy, chemotherapy either alone or in a combination of both. METHODS All clinically diagnosed patients of head and neck cancer requiring treatment using radiotherapy or chemotherapy alone or in combination having a normal hearing on pure tone audiometry (PTA) were enrolled in the study. All enrolled cases were divided into three groups namely A, B and C based on treatment received like radiotherapy, chemotherapy and combination respectively and their effect on hearing was compared. Hearing acuity was assessed by doing PTA before and after completion of treatment and at 6 months follow up in every case. RESULTS In groups A, B and C SNHL was noted at higher frequencies of 4 kHz and 8 kHz during 1st as well as final follow up. Hearing loss was found maximum in group C receiving combination treatment compared to the other two groups receiving in isolation. Hearing loss was the least in Group - A cases that received radiotherapy using the IMRT technique. CONCLUSIONS The possibility of SNHL is increased in cases receiving a combination of radio and chemotherapy (94 %). Extra care of shielding the cochlea is essentially required during treatment with high doses (> 60Gy) using conformal radiotherapy to limit the resultant radiotherapy-induced SNHL. Radiation-induced SNHL in the IMRT technique was the least (28 %) in the group - A cases and hence should be employed in every case. Future searches for cases of head and neck malignancy the newer effective combination of chemotherapeutic drug and radiation obviating the ototoxicity needs to be continued.

Background: Presbycusis is related to degenerative changes of aging resulting from deficient cochlear microcirculation. It is characterized by bilateral, symmetrical, sensorineural hearing loss (SNHL) in which recruitment and speech discrimination is affected in the absence of noise exposure. The objective of this study was to analyze the pure tone audiogram characteristics in Presbycusis. Methods: This descriptive study recruited n=192 cases of presbycusis of both genders, aged 50 to 80 years with convenience sampling technique. The study was conducted at Yusra General Hospital and the National Institute of Rehabilitation Medicine, Islamabad from1st July 2017 to 30th September 2017. Pure tone audiometry was used to collect audiometric data. SPSS-24 was used for data analysis. Chi-square and Pearson’s correlation were used to determine association between variables with p < 0.05 taken as significant. Results: Pure tone audiometry revealed 58 (30.2%) right and 65 (33.9%) left ears with high frequency gently sloping audiogram, while the second commonest configuration being high frequency steeply sloping curve in 51(26.6%) right and 52(27.1%) left ears. There was a significant correlation between the configuration of the audiogram and age with p=0.000, while no significant correlation with gender (p=0.71). The majority,77 (40.10%) right and 71(36.98%) of left ears had moderately severe hearing loss, while severe hearing loss was second commonest with 60(31.25%) right and 70(36.46%) left ears affected. The severity of hearing loss had a significant (P=0.000) positive correlation with age but no significant relationship with gender. Conclusion:  High frequency gently sloping audiogram was the commonest configuration followed by high frequency steeply sloping curve. Moderately severe hearing loss was most commonly seen followed by severe hearing loss.

Background: Outcome measures can be used to improve the quality of the rehabilitation by identifying and understanding which variables influence the outcome. This information can be used to improve outcomes for clients. In clinical practice, pure-tone audiometry, speech reception thresholds (SRTs), and speech discrimination scores (SDSs) in quiet or in noise are common assessments made prior to hearing aid (HA) fittings. It is not known whether SRT and SDS in quiet relate to HA outcome measured with the International Outcome Inventory for Hearing Aids (IOI-HA). Purpose: The aim of the present study was to investigate the relationship between pure-tone average (PTA), SRT, and SDS in quiet and IOI-HA in both first-time and experienced HA users. Research Design: SRT and SDS were measured in a sample of HA users who also responded to the IOI-HA. Study Sample: Fifty-eight Danish-speaking adult HA users. Data Collection and Analysis: The psychometric properties were evaluated and compared to previous studies using the IOI-HA. The associations and differences between the outcome scores and a number of descriptive variables (age, gender, fitted monaurally/binaurally with HA, first-time/experienced HA users, years of HA use, time since last HA fitting, best ear PTA, best ear SRT, or best ear SDS) were examined. A multiple forward stepwise regression analysis was conducted using scores on the separate IOI-HA items, the global score, and scores on the introspection and interaction subscales as dependent variables to examine whether the descriptive variables could predict these outcome measures. Results: Scores on single IOI-HA items, the global score, and scores on the introspection (items 1, 2, 4, and 7) and interaction (items 3, 5, and 6) subscales closely resemble those previously reported. Multiple regression analysis showed that the best ear SDS predicts about 18–19% of the outcome on items 3 and 5 separately, and about 16% on the interaction subscale (sum of items 3, 5, and 6) Conclusions: The best ears SDS explains some of the variance displayed in the IOI-HA global score and the interaction subscale. The relation between SDS and IOI-HA suggests that a poor unaided SDS might in itself be a limiting factor for the HA rehabilitation efficacy and hence the IOI-HA outcome. The clinician could use this information to align the user’s HA expectations to what is within possible reach.

Speech Discrimination

Diagnostic tests for hearing impairment not only determines the presence (or absence) of hearing loss, but also evaluates its degree and type, and provides physicians with essential data for future treatment and rehabilitation. Therefore, accurately measuring hearing loss conditions is very important for proper patient understanding and treatment. In current-day practice, to quantify the level of hearing loss, physicians exploit specialized test scores such as the pure-tone audiometry (PTA) thresholds and speech discrimination scores (SDS) as quantitative metrics in examining a patient’s auditory function. However, given that these metrics can be easily affected by various human factors, which includes intentional (or accidental) patient intervention, there are needs to cross validate the accuracy of each metric. By understanding a “normal” relationship between the SDS and PTA, physicians can reveal the need for re-testing, additional testing in different dimensions, and also potential malingering cases. For this purpose, in this work, we propose a prediction model for estimating the SDS of a patient by using PTA thresholds via a Random Forest-based machine learning approach to overcome the limitations of the conventional statistical (or even manual) methods. For designing and evaluating the Random Forest-based prediction model, we collected a large-scale dataset from 12,697 subjects, and report a SDS level prediction accuracy of 95.05% and 96.64% for the left and right ears, respectively. We also present comparisons with other widely-used machine learning algorithms (e.g., Support Vector Machine, Multi-layer Perceptron) to show the effectiveness of our proposed Random Forest-based approach. Results obtained from this study provides implications and potential feasibility in providing a practically-applicable screening tool for identifying patient-intended malingering in hearing loss-related tests.

Abstract Introduction. It is known that hyperlipidemia reduces hearing functions. In this study, we aimed to study the effect of antihyperlipidemic drugs on hearing functions and tinnitus. Methods. Eighty-four patients aged 18 to 84, who were diagnosed with hyperlipidemia and started treatment with the statin group (atorvastatin 20 mg and 40 mg, rosuvastatin 10 mg and 20 mg, and simvastatin 20 mg) of antihyperlipidemic drugs, were included in this study. All patients underwent pure-tone audiometry before starting treatment with antihyperlipidemic drugs. Patients with tinnitus were evaluated by Tinnitus Severity Index and Visual Analogue Scale. In the 6th month of therapy, otologic examination, pure-tone audiometry and tinnitus evaluation of the patients were repeated. Results. No significant difference was found in the pure-tone averages of the patients before and after statin use (p > 0.05). However, it was found in the audiometry that, after statin use, all drugs caused to statistically significant decrease in the hearing thresholds at 6000 Hertz (p < 0.05). Also, a strong increase was found in the Speech Discrimination percentages after treatment in patients using rosuvastatin 10 mg (p = 0.022). A significant decrease was found in the tinnitus frequency, duration, severity and degree of annoyance in patients using rosuvastatin 10 mg and 20 mg (p < 0.05). Conclusion. Statin group of drugs can have a positive effect on the hearing functions and subjective tinnitus. In particular, it is seen that rosuvastatin group of statins has a more notable effect on tinnitus. It was considered that further studies with larger patient groups are needed.
