Insights
Early treatment for sudden deafness with high-dose steroids and prostaglandin E1 (PGE1) significantly improves hearing outcomes. Prompt initiation, especially within 3 days for older patients, is crucial for optimal results in sudden hearing loss recovery.
Area of Science:
- Otolaryngology
- Neurology
- Pharmacology
Context:
- Sudden deafness, a condition affecting hearing, requires timely and effective treatment.
- The study investigates the efficacy of a combined high-dose steroid and prostaglandin E1 (PGE1) treatment regimen.
- 174 patients with sudden deafness treated within 7 days of onset were analyzed.
Purpose:
- To evaluate the effectiveness of combined high-dose steroid and PGE1 treatment for sudden deafness.
- To identify prognostic factors influencing hearing improvement.
- To determine the optimal timing for initiating treatment based on patient age.
Summary:
- Treatment initiated within 3 days of sudden deafness onset showed significantly better hearing outcomes than treatment initiated 4-7 days after onset (p < 0.001).
- Age and time from onset to treatment were significant prognostic factors for hearing improvement.
- In patients aged 50 and older, treatment initiated within 3 days was significantly more effective than treatment initiated 4-7 days after onset (p < 0.001).
Impact:
- The findings support the use of combined high-dose steroid and PGE1 treatment for sudden deafness, particularly when initiated early.
- Early intervention within 7 days of onset is recommended for all patients.
- A treatment window of within 3 days is strongly advised for patients aged 50 and older to maximize hearing recovery potential.
Abstract:
The efficacy of combined high-dose steroid and PGE1 treatment initiated immediately after the onset of sudden deafness was analyzed with the outcome of 174 patients begun on treatment within 7 days of the onset of sudden deafness. Four potential prognostic factors (days from onset to treatment, age, initial hearing level, presence of vertigo) and hearing outcome were examined with a multiple logistic regression analysis. Days from onset to treatment and age significantly correlated with hearing improvement. The efficacy of the treatment of patients begun on treatment within 3 days of the onset was significantly better than that of patients on treatment 4-7 days after the onset (p < 0.001). In the examination of patients younger than 50 years, the efficacy of the treatment of patients begun on treatment within 3 days of the onset didn't differ significantly from that of patients on treatment 4-7 days after the onset. On the other hand, in the examination of patients aged 50 years and older, the efficacy of the treatment of patients begun on treatment within 3 days of the onset was significantly better than that of patients on treatment 4-7 days after the onset (p < 0.001). These results suggest that significant efficacy may be expected from the combined high-dose steroid + PGE1 treatment, if its use is started within 7 days of the onset of sudden deafness, and started within 3 days of the onset of sudden deafness in patients 50 years old and older.
