Abstract
- BACKGROUND AND OBJECTIVES
Viral and vascular disorders are considered to be a major cause of idiopathic sudden sensorineural hearing loss (ISSNHL). Lipoprostaglandin Eâ‚ (lipo-PGEâ‚) has vasodilating activity and has been used to treat ISSNHL. The purpose of this study was to determine the specific therapeutic effects of lipo-PGEâ‚ and compare them to other treatment modalities for ISSNHL.
SUBJECTS AND METHODS
The study group had 1,052 patients diagnosed with ISSNHL. All were treated with steroid, carbogen inhalation, stellate ganglion block (SGB), or PGEâ‚. The CP group (steroid, carbogen inhalation, and PGE1 injection; 288 patients) was treated with lipo-PGEâ‚ and carbogen inhalation, the CS group (steroid, carbogen inhalation, and stellate ganglion block; 232 patients) with steroid, carbogen inhalation, and SGB, the C group (steroid and carbogen inhalation; 284 patients) with steroid and carbogen, and the control group (steroid only; 248 patients) with steroid only. Patients in the groups receiving lipo-PGEâ‚ received a continuous infusion of 10 µL lipo-PGEâ‚.
RESULTS
The overall recovery rate after treatment was 52.2%, and recovery rates by group were 67.7% in the CP group, 54.3% in the CS group, 52.1% in the C group, and 32.2% in the control group. Therefore, the therapeutic results in groups treated with lipo-PGEâ‚ were better than results in other groups. The difference was statistically significant.
CONCLUSIONS
The study results suggested that the CP group received effective treatment modalities for ISSNHL. The combined therapy of lipo-PGEâ‚ with carbogen inhalation in patients with ISSNHL was more beneficial than other treatment modalities.
