Summary
Sudden sensorineural hearing loss (SSNHL) can recur, with rates varying from 1.4% to 17%. Prognosis for recurrent SSNHL is highly variable, emphasizing the need for further research into risk factors and long-term outcomes.
Area of Science:
- Otolaryngology
- Audiology
- Epidemiology
Background:
- Sudden sensorineural hearing loss (SSNHL) is an emergent otologic condition requiring timely intervention.
- While many patients benefit from treatment, unexpected recurrences can occur.
- Understanding recurrence patterns is vital for patient management.
Purpose of the Study:
- To evaluate the recurrence rate of SSNHL.
- To present the prognosis for both first-episode and recurrent SSNHL.
- To identify potential risk factors for SSNHL recurrence.
Main Methods:
- A comprehensive literature search was performed using PubMed and Embase.
- Seven studies encompassing 3781 patients were included in the analysis.
- Data on recurrence rates, treatment, and recovery were extracted and synthesized.
Main Results:
- The overall SSNHL recurrence rate ranged from 1.4% to 17%, with an average time to recurrence of approximately 2 years.
- Recovery rates for first-episode SSNHL were 58%-79%, significantly wider for recurrent cases (21%-86%).
- No consistent risk factors for recurrence were identified, though low-frequency hearing loss, tinnitus, and elevated neutrophil-to-lymphocyte or platelet-to-lymphocyte ratios were suggested.
Conclusions:
- Knowledge of SSNHL recurrence rates, risk factors, and prognosis is essential for effective patient care.
- Further prospective studies with extended follow-up are needed to elucidate recurrence patterns and inform clinical practice.
- The variable prognosis for recurrent SSNHL underscores the complexity of the condition.
