    Abstract:
    BACKGROUND: Idiopathic sudden sensorineural hearing loss (ISSNHL) presents with emergent hearing impairment and is mainly treated with steroids. However, limited data exist regarding the prognostic factors among elderly patients (>65 years old) who receive an intra-tympanic steroid injection (ITSI). Therefore, we investigated the prognostic factors in these patients. METHODS: Between July 2016 and March 2022, we retrospectively enrolled 105 elderly patients (>65 years old) with unilateral ISSNHL who were treated with an ITSI, and recorded their clinical and audiological variables. RESULTS: The patients had a mean age of 72.03 ± 6.33 years and mean hearing level gain of 22.86 ± 21.84 dB, speech reception threshold (SRT) gain of 15.77 ± 35.27 dB, and speech discrimination score (SDS) gain of 19.54 ± 27.81 %. According to Siegel's criteria, 5 (4.76 %), 44 (41.91 %), 46 (43.81 %), and 10 (9.52 %) patients had complete recovery, partial recovery, slight improvement, and no improvement, respectively. In the univariate analysis, vertigo (odds ratio [OR] = 0.290, 95 % confidence interval [CI]: 0.130-0.651, p = 0.002) and profound hearing loss on pure tone audiometry (PTA; OR = 0.233, 95 % CI: 0.101-0.536, p = 0.004) were negative prognostic factors among elderly ISSNHL patients. In the multivariate analysis, vertigo (OR = 0.300, 95 % CI: 0.128-0.705, p = 0.005) and profound pure tone audiometry (OR = 0.240, 95 % CI: 0.101-0.570, p = 0.001) were independent adverse prognostic factors among elderly ISSNHL patients. CONCLUSIONS: We demonstrated the treatment outcomes of 105 elderly ISSNHL patients after an ITSI. Vertigo and profound PTA are independent adverse risk factors among elderly ISSNHL patients, and patients with these risk factors require active treatment.
