“…Further randomized controlled subject groups might contribute to determine prognostic factors of SSNHL. Keywords: Audiological configuration, delayed treatment, prognostic factors, sudden sensorineural hearing loss, systemic steroids Sudden sensorineural hearing loss (SSNHL) is defined as an acute onset, within a 72-hour period, with loss over 30 dB, in at least three consecutive frequencies in one or both ears (1)(2)(3). However, in clinical practice, the definition is expanded to cases with less than 30 dB loss or in 2 consecutive frequencies (1,4).…”

“…Also, certain drugs such as phosphodiesterase-5 inhibitors, ribavirin and interferon-α are among the rare causes of SSNHL (11,12). Approximately 85-90% of SSNHL cases are considered idiopathic and possible etiologic factors including infections (especially viral), autoimmune diseases and alterations of microcirculation (1,3,6,8,11). As the majority of patients have idiopathic SSNHL, treatment options also depend on hypotheses.…”

Background: Sudden sensorineural hearing loss (SSNHL) is still a complex and challenging process which requires clinical evidence regarding its etiology, treatment and prognostic factors. Therefore, determination of prognostic factors might aid in the selection of proper treatment modality. Aims: The aim of this study is to analyze whether there is correlation between SSNHL outcomes and (1) systemic steroid therapy, (2) time gap between onset of symptoms and initiation of therapy and (3) audiological pattern of hearing loss. Study Design: Retrospective chart review. Methods: Patients diagnosed at our clinic with SSNHL between May 2005 and December 2011were reviewed. A detailed history of demographic features, side of hearing loss, previous SSNHL and/or ear surgery, recent upper respiratory tract infection, season of admission, duration of symptoms before admission and the presence of co-morbid diseases was obtained. Radiological and audiological evaluations were recorded and treatment protocol was assessed to determine whether systemic steroids were administered or not. Treatment started ≤5 days was regarded as "early" and >5 days as "delayed". Initial audiological configurations were grouped as "upward sloping", "downward sloping", "flat" and "profound" hearing loss. Significant recovery was defined as thresholds improved to the same level with the unaffected ear or improved ≥30 dB on average. Slight recovery was hearing improvement between 10-30dB on average. Hearing recovery less than 10 dB was accepted as unchanged. Results: Among the 181 patients who met the inclusion criteria, systemic steroid was administered to 122 patients (67.4%), whereas 59 (32.6%) patients did not have steroids. It was found that steroid administration did not have any statistically significant effect in either recovered or unchanged hearing groups. Early treatment was achieved in 105 patients (58%) and 76 patients (42%) had delayed treatment. Recovery rates were no different in these two groups; however, when unchanged hearing rates were compared, it was statistically significantly lower in the early treatment group (p<0.05). When hearing outcomes were compared according to initial audiological pattern, significant recovery and unchanged hearing rates did not differ between groups; however, slight recovery rate was highest in the "flat" type audiological configuration (p<0.05). Conclusion: According to this patient series, oral steroid therapy does not have any influence on the outcomes of SSNHL. However, mid-frequency hearing loss of flat type and initiation of treatment earlier than 5 days from the onset of symptoms, seem to have positive prognostic effects. Further randomized controlled subject groups might contribute to determine prognostic factors of SSNHL.

We investigated vestibular function in patients with unilateral idiopathic sudden sensorineural hearing loss (ISSNHL) and vertigo, and assessed the relationship between hearing loss grade and cervical vestibular-evoked myogenic potentials (cVEMPs) and ocular VEMP (oVEMPs) findings. Material and Methods: The study included 31 patients diagnosed with unilateral ISSNHL and vertigo, and 26 healthy individuals (control group) with VEMP. In all participants, pure tone audiometry was used to assess the hearing threshold, and cVEMP and oVEMP tests were used to assess vestibular system function. The P1/N1 latency, P1-N1 interval and amplitude asymmetry ratio (AAR) were measured in the VEMP test. Additionally, the relationship between the VEMP findings and the degree of hearing loss was assessed. Results: We found no significant differences in VEMP parameters (N1 latency, P1-N1 interval, and amplitude) between the affected and control group ears (p>0.05). In contrast, the cVEMP P1 latency and AARs were significantly different between the patient and control groups (p=0.019 and 0.015, respectively). No significant differences were found in VEMP parameters (P1 latency, N1 latency, P1-N1 interval, and amplitude) or AAR in the patients with profound and nonprofound hearing loss in the cVEMP and oVEMP tests (p>0.05). Conclusions: Vestibular otolithic dysfunction can be detected using cVEMP and oVEMP in patients with ISSHL and vertigo. The VEMP amplitude asymmetry and VEMP responses have high diagnostic value in patients with ISSNHL with vestibular symptoms. Abnormal cVEMP responses provide more information than oVEMP responses about vestibular otolithic damage in patients with ISSHL. Although the saccule and utricle were affected in ISSNHL, the extent of saccular and utricular damage did not correspond to the amount of hearing loss.
