Pericondritis - Overview

Definición:

Es una infección de la piel y del tejido que rodea el cartílago de la oreja.

Causas, incidencia y factores de riesgo:

El cartílago es el tejido grueso que crea el contorno de la nariz y la oreja. Todo cartílago tiene una capa de tejido delgado alrededor denominada pericondrio. Esta cubierta ayuda a suministrar nutrientes al cartílago.

La bacteria que más comúnmente causa la infección de pericondritis es la Pseudomonas aeruginosa.

La pericondritis generalmente es ocasionada por lesión del oído debido a una cirugía, perforación del oído (especialmente perforación del cartílago) o por deportes de contacto. En la actualidad, la perforación del oído (piercing ) a través del cartílago es probablemente el factor de riesgo más significativo. Una cirugía, las quemaduras y la acupuntura también incrementan el riesgo de infección.

La pericondritis puede ocasionar un daño grave a la estructura del oído si ésta se convierte en condritis, una infección del cartílago en sí.
