          Abstract

          Introducción: La hipoacusia súbita es un cuadro clínico que presenta controversias tanto en su etiología, como en su tratamiento. Existen escasos estudios en la literatura nacional sobre este tema. Objetivo: Evaluar la incidencia del cuadro de hipoacusia súbita en un año, en el Hospital Clínico de la Universidad de Chile, analizar características epidemiológicas, clínicas, y del tratamiento. Material y método: Estudio retrospectivo realizado en el Hospital Clínico de la Universidad de Chile, revisando fichas clínicas entre Diciembre del año 2004 hasta Noviembre de 2005, con diagnóstico de hipoacusia súbita. Resultados: Se realizó el estudio con 43 pacientes con diagnóstico de hipoacusia súbita. La mayoría recibió tratamiento corticoidal. El 28% de los pacientes mejoraron, el 18,7% tuvo una recuperación parcial, 9,3% recuperación total, no presentaron mejoría el 72%. Se encontró asociación entre menor edad y mejoría en forma casi significativa. Se encontró una asociación entre mejoría y compromiso del oído derecho en forma significativa. Conclusión: La mayoría de los hallazgos son comparables con la literatura nacional e internacional, la asociación mejoría v/s oído derecho debe ser validada por nuevos estudios.

          Introduction. Sudden hearing loss (SHL) is a medical condition somewhat controversia! in its etiologyand treatment. There are fewreports of SHL in the local literature. Aim. Jo assess the incidence of SHL at the University of Chile Hospital during a year-long period, analyzing the epidemiological, clinical and treatment characteristics. Material and Method. Restrospective review of SHL clinical data between December 2004 and November 2005. Results. Forty three patients diagnosed with SHL were included. Most were treated with corticoids. In 28% of cases, there was an improvement ofthe condition. Ofthese, in 18.7% there was a partial improvement, and in 9.3% a compiete recovery. There was no improvement in 72% of the cases. The relation between age and recovery was almost significant. A significant relation between improvement andright ear involvement was found. Conclusión. Most of our findings are similar to those reponed in the literature; the association between recovery an right ear involvement should be validated by Mure studies.

          Sudden sensorineural hearing loss.

          Sudden sensorineural hearing loss is usually unilateral and can be associated with tinnitus and vertigo. In most cases the cause is not identified, although various infective, vascular, and immune causes have been proposed. A careful examination is needed to exclude life threatening or treatable causes such as vascular events and malignant diseases, and patients should be referred urgently for further assessment. About half of patients completely recover, usually in about 2 weeks. Many treatments are used, including corticosteroids, antiviral drugs, and vasoactive and oxygen-based treatments. Although no treatment is proven, we recommend a short course of oral high-dose corticosteroids. There is much to learn about pathogenesis of sudden sensorineural hearing loss, and more clinical trials are needed to establish evidence-based management. Copyright 2010 Elsevier Ltd.

            Sudden hearing loss: eight years' experience and suggested prognostic table.

            F M Byl (1984)
            The etiology, incidence, acute and late prognosis, and treatment of sudden hearing loss (SHL) are described variously in the literature. In an 8-year prospective study of 225 SHL patients, initiated in July 1973, overall, normal, or complete recovery occurred in 45% of patients and late otologic complications in 28%. Important prognostic indicators were severity of initial hearing loss and vertigo, time to initial audiogram, and elevated erythrocyte sedimentation rate; other indicators were age greater than 60 and less than 15 years, midfrequency audiogram configuration, and hearing status of the opposite ear. A common inflammatory cause is suggested for all degrees of severity in SHL, and a prognostic table is provided to aid the practitioner in predicting recovery. There is still no evidence that treatment achieves a result better than expected with spontaneous recovery.

              The efficacy of steroids in the treatment of idiopathic sudden hearing loss. A double-blind clinical study.

              Double-blind studies were conducted for the treatment of idiopathic sudden hearing loss (ISHL) with oral steroids. The condition was defined as not less than a 30-dB loss over three contiguous frequencies in three days or less. Follow-up audiograms were obtained four weeks and three months later. Specific audiologic guidelines for the assessment of hearing recovery were used to ensure objectivity. Steroids had a statistically significant effect on the recovery of hearing in patients with moderate hearing losses. The nature of the hearing loss and its susceptibility to improvement with steroid therapy lend support to the hypothesis that viral cochlitis is the primary cause of ISHL.
