Depending on timing, intra-tympanic steroid injection is also offered (dexamethasone 10-24mg/cc). Intra-typmpanic steroid injection is performed by inserting a needle through the eardrum and injecting about of highly concentrated steroids directly into the middle ear space. The patient is than instructed to keep the affected ear up for 30 minutes without swallowing, yawning, or popping the ear. After injection, the patient is allowed to immediately resume normal activities. This steroid injection has also been used to treat Meniere's Disease flare-ups.
A total of 16 patients (%) had hearing loss greater than 90 dB with an improvement rate of %; a total of 29 patients (%) had hearing loss of 90 dB or less and greater than to 50 dB with improvement rate of %; a total of 10 patients (%) had hearing loss less than 50 dB and greater than 30 dB with an improvement rate of % (Figure 3 ). Patients with severe losses greater than 90 dB had a poorer recovery (%) compared with losses less than 90 dB (%) ( 𝑃 = 0 . 0 6 Fisher’s test).
SSNHL may be a risk factor for stroke. In a study of patients in Taiwan hospitalized for treatment of a first episode of SSNHL, the risk of stroke over a five-year follow-up period was increased compared with patients of similar age and demographics hospitalized for appendicitis (hazard ratio [HR] , 95% CI -) [ 9 ]. However, in a review of the literature, the committee developing 2012 guidelines for the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) found that the relationship between SSNHL and risk of stroke did not meet their threshold for significance [ 3 ]. SSHNL has also been associated with an increased risk for myocardial infarction later in life [ 10 ].
