Hearing outcome of sudden sensorineural hearing loss: Long-term follow-up

OBJECTIVE: To evaluate the time-dependent progress and delayed improvement in patients who were treated with combination therapy including oral corticosteroid for idiopathic sudden sensorineural hearing loss. STUDY DESIGN AND SETTING: This retrospective study at a secondary referral and university-based center included 156 patients who were treated by 10-day course of admission therapy and followed for at least three months. RESULTS: Of 121 patients who recovered over three months of follow-up, 45.5% showed a delayed recovery after the end of 10-day course of therapy. Of these 55 patients, 78.2% recovered within one month, 5.5% recovered within one to two months, 12.7% recovered in two to three months, and 3.6% recovered later than three months after discharge. CONCLUSIONS: This Study describes the long-term results for a three-month retrospective series of 156 patients diagnosed with idiopathic sudden sensorineural hearing loss, although this result should be further studied by additional research.
