Background Ménière's disease is a condition that causes recurrent episodes of vertigo, associated with hearing loss and tinnitus. Corticosteroids are sometimes administered directly into the middle ear to treat this condition (through the tympanic membrane). The underlying cause of Ménière's disease is unknown, as is the way in which this treatment may work. The efficacy of this intervention in preventing vertigo attacks, and their associated symptoms, is currently unclear. Objectives To evaluate the benefits and harms of intratympanic corticosteroids versus placebo or no treatment in people with Ménière's disease. Search methods The Cochrane ENT Information Specialist searched the Cochrane ENT Register; Central Register of Controlled Trials (CENTRAL); Ovid MEDLINE; Ovid Embase; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials. The date of the search was 14 September 2022. Selection criteria We included randomised controlled trials (RCTs) and quasi‐RCTs in adults with a diagnosis of Ménière's disease comparing intratympanic corticosteroids with either placebo or no treatment. We excluded studies with follow‐up of less than three months, or with a cross‐over design (unless data from the first phase of the study could be identified). Data collection and analysis We used standard Cochrane methods. Our primary outcomes were: 1) improvement in vertigo (assessed as a dichotomous outcome ‐ improved or not improved), 2) change in vertigo (assessed as a continuous outcome, with a score on a numerical scale) and 3) serious adverse events. Our secondary outcomes were: 4) disease‐specific health‐related quality of life, 5) change in hearing, 6) change in tinnitus and 7) other adverse effects (including tympanic membrane perforation). We considered outcomes reported at three time points: 3 to < 6 months, 6 to ≤ 12 months and > 12 months. We used GRADE to assess the certainty of evidence for each outcome. Main results We included 10 studies with a total of 952 participants. All studies used the corticosteroid dexamethasone, with doses ranging from approximately 2 mg to 12 mg. Improvement in vertigo Intratympanic corticosteroids may make little or no difference to the number of people who report an improvement in their vertigo at 6 to ≤ 12 months follow‐up (intratympanic corticosteroids 96.8%, placebo 96.6%, risk ratio (RR) 1.00, 95% confidence interval (CI) 0.92 to 1.10; 2 studies; 60 participants; low‐certainty evidence) or at more than 12 months follow‐up (intratympanic corticosteroids 100%, placebo 96.3%; RR 1.03, 95% CI 0.87 to 1.23; 2 studies; 58 participants; low‐certainty evidence). However, we note the large improvement in the placebo group for these trials, which causes challenges in interpreting these results. Change in vertigo ...

Comparison of Intratympanic, Systemic, and Combined Steroid Therapies for Sudden Sensorineural Hearing Loss in Patients with Diabetes Mellitus
IntroductionSudden sensorineural hearing loss (SSNHL) is an otologic emergency. SSNHL is commonly defined as hearing loss of greater than 30 dB involving at least three consecutive frequencies and occurring within a 3-day period. 1) There are many hypotheses regarding the etiology of SSNHL, including those implicating viral infection, vascular compromise, and immune-mediated responses. 2) Patients diagnosed with-Background and Objectives We investigated whether the intratympanic steroid injections might be an effective initial treatment for sudden sensorineural hearing loss (SSNHL) in patients with diabetes mellitus (DM). Subjects and Method We assessed a total of 167 patients with DM and SSNHL who visited a tertiary referral otolaryngology department between January 2010 and April 2018. Fortytwo patients with DM and SSNHL received intratympanic steroid injections; 48 patients with DM and SSNHL received systemic steroid treatment; and 77 patients with DM and SSNHL received a combination of systemic and intratympanic treatment. Initial and post treatment hearing levels and fasting blood sugar (FBS) were assessed, and correlations between hearing gain and the duration of DM, HbA1c, FBS were investigated. Results After steroid treatment, hearing levels were 38.87±25.35 dB in the intratympanic injection group, 41.09±28.49 dB in the systemic steroid treatment group, and 47.81±27.12 dB in the combined treatment group. Final hearing levels and hearing gain in the three groups did not differ significantly. FBS after treatment in the systemic steroid treatment and combined steroid treatment group worsened relative to the intratympanic injection group (202.00±9.40 mg/dL to 326.63±7.85 mg/dL). FBS, duration of DM, and HbA1c levels did not affect the hearing gain in patients with DM and SSNHL. Conclusion Intratympanic steroid injections are comparable to the systemic steroid treatment modality for SSNHL in patients with DM. Thus, intratympanic steroid injections may serve as an effective initial treatment modality for SSNHL in patients with DM.
