Imagen de la hipoacusia postraumática / Imaging of post-traumatic hearing loss

Objetivo. La hipoacusia es la complicación más frecuente del traumatismo del hueso temporal. El papel del radiólogo es de gran importancia; la adecuación y la selección de las pruebas radiológicas, así como su correcta interpretación, son cruciales para establecer el diagnóstico y el pronóstico, y para seleccionar el tratamiento idóneo. Con el objetivo de sistematizar los conceptos más relevantes en la valoración de los estudios de imagen en este contexto, se esquematizará el desarrollo del tema según el tipo de hipoacusia que condicione el traumatismo. De forma ordenada se valorarán las potenciales lesiones de sus componentes; en cada caso se sugerirá la técnica de imagen para su evaluación y se describirán e ilustrarán los hallazgos. Conclusión. En la hipoacusia postraumática, la tomografía computarizada es la técnica de elección inicial y permitirá la detección de alteraciones que condicionen hipoacusia conductiva; la resonancia magnética es útil en la valoración de la hipoacusia neurosensorial

Objective. Hearing loss is the most frequent complication of temporal bone trauma. The role of the radiologist is of great importance; the adequacy and selection of the imaging technique, as well as its correct interpretation, are crucial to establish the diagnosis, prognosis and enable the selection of appropriate treatment. With the aim of systematizing the most relevant concepts in the evaluation of image studies in this scenario, this review will be outlined according to the hearing loss type. The potential lesions of its components will be assessed; In each case the most appropriate imaging technique will be suggested and the findings will be described and depicted. Conclusion. In postraumatic hearing loss, computed tomography is the initial technique of choice and will allow the detection of alterations that cause conductive hearing loss; magnetic resonance imaging will be useful in the evaluation of sensorineural hearing loss
