“…In our study (as reported by many other Authors) 18,20,[22][23][24][27][28][29]31 with the exception of Lissens et al 32 the presence of objective vertigo (which indicates complex damage to the inner ear) must be considered as a negative prognostic factor of hearing recovery. Therefore, the importance of initial record-taking cannot be sufficiently stressed in terms of its prognostic value.…”

“…25,26 As stated in other studies 10,17,22,23,27 sudden hypoacusis requires hospitalization and medical treatment as soon as possible. 28,29 In contrast, Massen et al 30 observed improvements in hearing even when the beginning of the treatment was delayed, and Baujat et al 20 stated that sudden hypoacusis is a false medical emergency because the results are disappointing even when treatment is prompt.…”

Sudden sensorineural hearing loss: role of hyperbaric oxygen therapy

et al. 2017

Sudden sensorineural hearing loss is defined as an acute hearing reduction of 30 dB or more, in at least three consecutive frequencies, occurring within 3 days of symptom onset. There is no consensus on the best treatment option. The aims of this paper were to evaluate the effectiveness of a treatment protocol based on medical therapy combined with hyperbaric oxygen therapy and to examine the factors that influence the recovery of hearing (age, gender, the amount of time between the onset of symptoms and the initiation of treatment -time since onset -, audiometric curve type and objective vertigo). Audiometric results were evaluated according to Siegel's criteria. In patients treated also with hyperbaric oxygen therapy we observed complete resolution in 44.1% of the patients, partial resolution in 37.2%, slight improvement in 10.5% and no improvement in 8.2% of the patients. This resolution pattern was significantly different from that observed in the patients treated only with medical therapy. The factors associated with a better prognosis were young age, rapid intervention, upward sloping or pantonal audiometric patterns and the absence of objective vertigo. Gender appeared to be an insignificant factor. Medical treatment associated with hyperbaric oxygen therapy gives better results in terms of hearing gain compared to exclusive medical treatment.

“…The negative prognostic effect of profound or total hearing loss is almost agreed worldwide. However, in the literature, there are certain studies which report poor prognosis with flat type or low frequency losses which is an inconsistent finding with the majority of the rest (18,25). This might be attributable, to a certain point, to various classification patterns or diverse treatment modalities utilized by different authors.…”

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.

“…More importantly, older age (>60 years) was shown to have a negative prognostic impact with 55.9% of the cases in this age group having no recovery (p=0.046). Although some previous reports have shown that older age is related to negative prognosis [17] , others have found no correlation between age and prognosis [16,18,19] . By contrast, younger patients were reported to have a better prognosis by some authors [20] .…”

OBJECTIVE:The objective was to identify and evaluate factors that may influence the recovery rate in patients with idiopathic sudden sensorineural hearing loss (ISSNHL). MATERIALS and METHODS:A retrospective analysis was performed for patients with sudden sensorineural hearing loss between 2009 and 2013. Those with an identified etiology were excluded. The patients were divided into four treatment groups: (i) systemic corticosteroids (SC) only, (ii) SC+low-molecular-weight heparin (LMWH), (iii) SC+hyperbaric oxygen (HBO), and (iv) SC+LMWH+HBO. Recovery was evaluated according to Siegel's criteria. Age, initial hearing level, onset, treatment and audiogram types, comorbidities, and associated tinnitus and vestibular symptoms were investigated for their impact on prognosis. RESULTS:Two hundred five patients with ISSNHL were included. Recovery was seen in 59% of the patients. The complete recovery rate was significantly lower in patients older than 60 years and in patients presenting with profound hearing loss. Different audiogram curves had no significant effect on recovery. Sudden hearing loss was accompanied by tinnitus in 107 (52.1%) patients and vestibular symptoms in 55 (26.8%); however, neither was noted to affect prognosis. Different treatment combinations did not significantly affect prognosis. However, hypertension and a delay in treatment by more than 10 days from the onset of hearing loss were associated with a worse prognosis. CONCLUSION:Profound hearing loss, older than 60 years, a delay in treatment by more than 10 days, and hypertension were negative prognostic factors in this study, whereas, the type of audiogram curve and addition of HBO to SC did not affect prognosis.
