Sudden sensorineural hearing loss () can occur suddenly in one ear, and generally within three days, causing a 30+ hearing loss at three consecutive frequencies. The cause for this disorder is unclear, but research has indicated that viral infection, vascular compromise, and immunologic diseases could be key reasons for this hearing disorder. Treatment of SSNHL remains controversial. Different approaches such as steroids, vasodilator, antiviral agents, diuretics, and low-salt diets have been suggested. Nevertheless, spontaneous recovery rate without treatment ranges from 30 to 60%, most resolving within two weeks after onset.
As a result of its anti-inflammatory effect, high-dosage systemic steroid therapy is currently the mainstay of the treatment for SSNHL. Despite oral or intravenous steroid therapy for 2 weeks, approximately 30-50% of patients show no response. Animal studies have found that intratympanic steroid injections—introducing steroids through the tympanic membrane—results in reduced systemic steroid toxicity and higher perilymph steroid level selectively.
A new study evaluates the effect of intratympanic steroid injections in patients with SSNHL after failure to respond to systemic steroid treatment. Patients who refused this regimen were used as controls in this research. The authors of “Intratympanic Steroids for Treatment of Sudden Hearing Loss After Failure of Intravenous Therapy,” are Guillermo Plaza, MD, PhD, from the Otolaryngology Department, Hospital de Fuenlabrada, and Carlos Herráiz, MD, PhD, with the Otolaryngology Department, Fundación Hospital Alcorcón, both in Madrid, Spain. Their findings were presented at the 110th Annual Meeting and OTO EXPO of the American Academy of Otolaryngology—Head and Neck Surgery Foundation, held September 17-20, 2006, in Toronto.
