Summary
Sudden sensorineural hearing loss in five males responded well to steroids, which quickly restored hearing. However, hearing loss returned upon steroid cessation, indicating a steroid-sensitive, low-frequency hearing loss.
Area of Science:
- Otolaryngology
- Neurology
- Audiology
Background:
- Sudden sensorineural hearing loss (SSNHL) is an otolaryngologic emergency requiring prompt diagnosis and treatment.
- The etiology of SSNHL is often idiopathic, necessitating empirical treatment strategies.
- Low-frequency hearing loss is a common presentation of SSNHL.
Observation:
- Five male patients with sudden onset sensorineural hearing loss were identified.
- All patients presented with hearing impairment predominantly in the low frequencies on pure tone audiometry.
- Initial treatment with Adenosine Triphosphate (ATP) and Vitamin B12 (Vit. B12) showed no improvement.
Findings:
- Rapid and significant hearing recovery was observed following steroid administration.
- Discontinuation of steroid therapy led to a recurrence of hearing impairment.
- Standard serological and immunological tests were unremarkable in all patients.
Implications:
- These cases suggest a specific subtype of sensorineural hearing loss that is highly sensitive to steroid treatment.
- The findings highlight the potential efficacy of steroids in managing certain cases of sudden, low-frequency hearing loss.
- Further research into the underlying mechanisms of steroid-responsive SSNHL is warranted.
