“…Each patient was instructed to report in which ear the vibrating sound was heard louder. The result was considered positive when the sound was lateralized to the nonaffected ear.‬ The smartphone-based vibration test has been validated for SSNHL and found to be in high agreement with the traditional tuning fork at a frequency of 512 Hz, which is the most sensitive frequency for detecting SSNHL …”

IMPORTANCE Developing a telemedicine tool to discriminate between patients who need urgent treatment for sudden sensorineural hearing loss (SSNHL) from those who do not takes on special importance during the COVID-19 pandemic.OBJECTIVE To explore the feasibility of a telemedicine model to assist in the evaluation of new-onset unilateral sudden hearing loss (SHL) among patients who do not have access to medical resources, especially during the COVID-19 pandemic.DESIGN, SETTING, AND PARTICIPANTS This prospective cohort investigation of a telemedicine model was conducted at a tertiary referral medical center between May 2020 and January 2021, with the interpreting physician blinded to the results of formal audiograms. The study included a consecutive sample of adult patients (aged Ն18 years) referred to the otolaryngology emergency department in our medical center with the chief complaint of new-onset unilateral SHL. INTERVENTIONSThe telemedicine model comprised 2 sequential steps: a Weber test using the Hum Test and a smartphone-based vibration, and uHear app-based audiometry.MAIN OUTCOMES AND MEASURES Discrimination between patients with and without SSNHL by using the telemedicine model. All diagnoses subsequently confirmed by a formal audiogram.RESULTS Fifty-one patients with new-onset unilateral SHL participated in the study study (median age, 45 [range, 18-76] years; 28 [54.9%] men). The sensitivity and specificity of the telemedicine model for fulfilling the audiometric criteria of SSNHL (loss of Ն30 dB in Ն3 consecutive frequencies) were 100% (95% CI, 84%-100%) and 73% (95% CI, 54%-88%), respectively. The PPV was 72% (95% CI, 53%-87%), the NPV was 100% (95% CI, 85%-100%), and the accuracy was 84.3% (95% CI, 71%-93%). Although 8 participants had false-positive results, all of them had SSNHL that did not meet the full audiometric criteria. CONCLUSIONS AND RELEVANCEThe telemedicine model presented in this study for the diagnosis of SSNHL is valid and reliable. It may serve as a primary tool for the discrimination between patients in need of urgent care for SSNHL from those who are not, especially during the COVID-19 pandemic.

Pure-tone thresholds have long served as a gold standard for evaluating hearing sensitivity and documenting hearing changes related to medical treatments, toxic or otherwise hazardous exposures, ear disease, genetic disorders involving the ear, and deficits that develop during aging. Although the use of pure-tone audiometry is basic and standard, interpretation of thresholds obtained at multiple frequencies in both ears over multiple visits can be complex. Significant additional complexity is introduced when audiometric tests are performed within ototoxicity monitoring programs to determine if hearing loss occurs as an adverse reaction to an investigational medication and during the design and conduct of clinical trials for new otoprotective agents for noise and drug-induced hearing loss. Clinical trials using gene therapy or stem cell therapy approaches are emerging as well with audiometric outcome selection further complicated by safety issues associated with biological therapies. This review addresses factors that must be considered, including test-retest variability, significant threshold change definitions, use of ototoxicity grading scales, interpretation of early warning signals, measurement of notching in noise-induced hearing loss, and application of age-based normative data to interpretation of pure-tone thresholds. Specific guidance for clinical trial protocols that will assure rigorous methodological approaches and interpretable audiometric data are provided.
