Idiopathic sudden sensorineural hearing loss: prognostic factors

Abstract

The present study revealed that there are certain factors that affect prognosis in idiopathic SSHL. This is very important in counselling patients and may affect current clinical practice.

Effects and Prognostic Factors of Acupuncture Treatment for Idiopathic Sudden Sensorineural Hearing Loss

“…If the 10 patients within 2 weeks from the onset were excluded to eliminate the effect from nature spontaneous recovery, 43.5% patients (27/62) showed clear or partial improvement. These results were similar to or higher than average recovery rate of other studies especially considering the time interval from onset of ISSHL to start treatment ( Xenellis J et al, 2006;Haynes DS et al, 2007;Raymundo IT et al, 2010;Wu HP et al, 2011;Rauch SD et al, 2011;Park MK et al, 2011).…”

“…have been suggested. Some studies have reported that the female gender was suggested to be poor prognostic factor for recovery of hearing loss (Ceylan et al, 2007) and male gender was related to better hearing outcomes (Xenellis J et al, 2006). In our study, correlation between gender and prognosis for recovery of hearing loss was not evident.…”

“…There is not even universally acceptable standard definition of ISSHL. Although many studies define ISSHL as loss of at least 30 dB in 3 contiguous frequencies over a period of 3 days (Shemirani et al, 2009, Xenellis J., 2006, some studies defined as a >20 dB (Haberkamp & Tanyeri, 1999), and others defined ISSHL as a >25 dB loss. (BYL FM, 1984).…”

“…We decided the criterion valuation basis for effectiveness at least 10 dB decrease in PTA of contiguous 4 frequencies (250, 500, 1000, 2000 Hz) because most of patients visited our clinic after they failed to conventional therapies, so we considered that 10 dB was reasonable comparing other studies (Xenellis J et al, 2006;Rauch SD et al, 2011;Wu HP et al, 2011) After completing the AT, 50% patients (36/72) showed clear or partial improvement. If the 10 patients within 2 weeks from the onset were excluded to eliminate the effect from nature spontaneous recovery, 43.5% patients (27/62) showed clear or partial improvement.…”

A study of clinical and audiometric profile in patients presenting with sudden sensorineural hearing loss

“…Increasing age was found to be associated with poorer prognosis in most of the studies. 2,10,11 However, in a retrospective study which was conducted to find out the factors that affect hearing outcome, the result indicated that age of the patient had no effect on the outcome of hearing.…”
