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.
Some reports maintain that a cold or other upper respiratory illness preceded the onset of SSNHL in as many as 40 percent of cases. Unfortunately, these reports lack corresponding data on the comparative frequency of upper respiratory illness in a matched control population. What about the evidence of blood examinations? In response to a virus, the immune system produces a temporary increase in the level of antibodies against the speciﬁc virus, and many case reports on patients with SSNHL show that they experience a brief, sharp rise in antibody levels against common viruses such as herpes, ﬂu, mumps, or rubella.
