    Abstract:
    OBJECTIVE: Endolymphatic sac decompression surgery (ELSD) may be used to treat patients who have Menière's 's disease refractory to medical therapy. In this study, we investigated whether or not the injection of steroid into the endolymphatic sac at the time of ELSD provides additional benefit to patient outcomes. STUDY DESIGN: Randomized prospective single-blinded placebo-controlled study. SETTING: Tertiary center. PATIENTS: Patients with Menière's disease with poorly controlled vertigo despite medical therapy and serviceable hearing that were offered ELSD. INTERVENTION(S): Patients randomized into two groups, with control group (n = 17) undergone ELSD without steroid injection and experimental group undergone ELSD with steroid injection (n = 18) MAIN OUTCOME MEASURE(S):: Audiogram, dizziness handicap inventory, tinnitus handicap inventory, frequency of vertigo spells, functional level scale, and quality of life were obtained at multiple intervals from preoperatively to 24 months postoperatively. RESULTS: ELSD resulted in a statistically significant improvement in vertigo control whether or not steroid was injected into the endolymphatic sac at the time of surgery. However, no additional benefit was observed with the addition of intra-sac steroid injection. No statistical difference in pure-tone average, tinnitus handicap inventory, dizziness handicap inventory, or quality of life was observed between the steroid and nonsteroid surgical groups up to 24 months postoperatively. CONCLUSION: ELSD is an effective treatment for Menière's disease refractory to medical therapy; however, the addition of intra-sac steroid injection at the time of surgery does not seem to result in a further improvement in patient outcomes.
