The Effects of Prognostic Factors in Idiopathic Sudden Hearing Loss

Abstract

Introduction Sudden hearing loss is one of the otologic emergencies. The treatment of this disease is affected negatively by some prognostic factors. Objective In this study, the effects of early treatment initiation in patients with idiopathic sudden hearing loss and of prognostic factors in early treated patients were investigated. Methods Out of the 216 patients admitted between September 2007 and September 2015, 154 were identified as having idiopathic sudden hearing loss; they were followed-up for a mean time of 7.4 months, and evaluated retrospectively. The effects of several parameters on the success of the treatment were statistically evaluated, such as the time the treatment was initiated, being of the female gender, the severity of the hearing loss, having descending type audiogram patterns, being older than 60 years old, and the co-presence of vertigo. Results Success rates were found to be significantly higher in idiopathic hearing loss patients that were admitted within the first week ( p < 0.05) of the onset of the hearing loss. However, the outcomes were found to be similar when patients admitted within the first 3 days and 4–7 days after the occurrence of the hearing loss were compared ( p > 0.05). Parameters such as female gender, severe hearing loss, descending type audiogram, being older than 60 years old, and co-presence of vertigo didn't reveal statistically significant effects on the outcome ( p >0.05). Conclusion The aforementioned prognostic factors, which are well-known in the literature, did not have significant effects when the idiopathic sudden hearing loss treatment was initiated within the first 7 days of the onset of the hearing loss.

“…Childhood is considered to be a poor prognostic factor (1,6). In addition to studies reporting a better recovery rate in younger patients, there are studies reporting that there is no relationship between age and SISHL prognosis (15)(16)(17)(18)(19). In our study, it was determined that the age of the patients did not have a significant effect on hearing loss levels and hearing gain levels.…”

“…Kaplan et al (9) reported in their study that as the severity of hearing have loss increases, the success achieved with treatment decreases, and therefore the severity of hearing loss is an important prognostic factor. Bulgurcu et al (19), determined complete recovery in 55 % of the patients with a loss of more than 70dB and partial recovery in 58% of them. The authors interpreted this situation as the earlier admission of patients with severe hearing loss to the hospital.…”

Research progress in refractory sudden hearing loss: steroid therapy

“…Multiple prognostic factors affecting sudden deafness have been reported, including patient age, absence of vertigo and tinnitus, degree of hearing loss, shape of the audiogram, and time between the onset and treatment of SSNHL. [23][24][25][26][27] In China, there is presumably a large population of individuals with RSHL, although the incidence of this condition in China has not yet been reported. Although steroid therapy is generally believed to be effective in RSHL, [12][13][14]28 few studies have examined the correlation between prognosis and type, duration, and administration route of steroid treatment.…”

“…However, the causes in the majority of cases are unknown 1,3 . The time to start treatment, type of audiogram, presence of vertigo, degree of hearing loss, age and gender has been used to determine the prognosis of SSNHL 4 .…”
