Colesteatoma
Definición:
Es un tipo de quiste localizado en el oÃdo medio.
Causas, incidencia y factores de riesgo:
El colesteatoma puede ser un defecto congénito (presente al nacer), pero se da más comúnmente como complicación de una infección crónica del oÃdo .
La inflamación prolongada en la trompa de Eustaquio puede provocar una presión negativa en el oÃdo medio; esto empuja a una parte del tÃmpano (membrana timpánica) en forma equivocada, creando un saco o quiste que se llena con células cutáneas viejas y otros materiales de desecho. El quiste se puede infectar y puede causar el desgaste de algunos huesos del oÃdo.
