“…One study (17) used a 20 dB hearing loss in three consecutive major frequencies over no more than 72 hours as the definition of an SSNHL. Four (reference numbers [20,23,25,26] in Table 1) of the 13 enrolled papers did not provide the criteria used for defining an SSNHL. 15) studies included 45,277, 9,267, and 4,753 cases of SSNHL, respectively, whereas the other studies had between 68 to 320 cases of ISSNHL.…”

ObjectiveTo investigate the circannual rhythm (seasonal incidence) of idiopathic sudden sensorineural hearing loss (ISSNHL).MethodsData were retrieved from the medical files of an original cohort of all consecutive patients with ISSNHL in a tertiary medical center between 2012 and 2020. A systematic literature search of “MEDLINE” via “PubMed,” “Embase,” and “Web of Science” on comparable published cases was performed. A Google Trends analysis of the term [sudden hearing loss] and related terms between 2014 and 2020 was also performed.ResultsMost of the published series (9/12) reported the highest ISSNHL incidence in the spring and the lowest in the winter (8/12). In our local series, the incidence during the winter was significantly lower than that for the other seasons by a factor of 0.69 (95% confidence interval, 0.65–0.77; p = 0.041; r = 0.36). Google Trends data showed no significant correlation between the calendric month and the incidence of ISSNHL in any of the analyzed countries (p = 0.873, r2 = 0.029).ConclusionThe ISSNHL incidence was lowest during the winter season in our cohort and reported for other cohorts worldwide. Google Trends–based model analysis did not determine any circannual rhythm.

“…Some researchers reported a significant relationship between the onset of ISSHL and weather conditions [5,6,19], while others reported no relationship between weather conditions and the development of ISSHL [7,8]. There are limited studies investigating the relationship between ISSNHL prognosis and meteorological factors [7,22]. The relationship between the daily temperature range and the recovery rates of sudden hearing loss remains unclear.…”

To evaluate the effect of air pollution parameters and meteorological factors on the prognosis of idiopathic sudden sensorineural hearing loss (ISSNHL). Methods: 40 patients diagnosed with ISSNHL who were treated in our clinic between 2015 and 2018 were examined retrospectively. Meteorological data including average temperature (Tmean), maximum and minimum temperature (Tmax and Tmin), relative humidity, and air pollution parameters including sulfur dioxide (SO2) and particulate matter (PM 10). Data of 10 days prior to the disease and 14 days after the treatment were analyzed. Results: When the distribution of patients according to the seasons were examined, it was found that 12 (30%) of the patients were seen in autumn, 11 (27.5%) in spring, 9 (22.5%) in winter, and 8 (20%) in summer. When the Tmax, Tmin, Tmean values obtained as of the initiation of the treatment were compared, it was found that the values of the group without recovery were significantly lower. Relative humidity values were significantly lower in the group without recovery in pre-treatment and post-treatment measurements. No significant difference was found between the recovery groups in SO2 and PM10 values in pre-treatment and post-treatment measurements. Conclusion: It was observed that relative humidity, Tmax, Tmin, Tmean values may affect prognosis in ISSNHL patients in our study. In addition, SO2 and PM10 were not associated with ISSNHL recovery rates. Our study is the first in the literature in terms of evaluating the relationship between air pollution parameters and ISSNHL prognosis.
