Examen del oído - Results

Nombres alternativos

Otoscopia

Valores normales:

El conducto auditivo externo de todas las personas varía en tamaño, forma y color. Normalmente, este conducto es del color de la piel y tiene vellosidades pequeñas. Puede haber cerumen de color marrón amarillento. El tímpano es de un color gris claro o blanco perla brillante. La luz se debe reflejar de la superficie timpánica.

Significado de los resultados anormales:

Las infecciones del oído son un problema común, especialmente en niños pequeños. Un reflejo de la luz débil o ausente del tímpano puede ser un signo de presencia de líquido o infección en el oído medio. El tímpano puede estar rojo y protuberante si hay una infección. Con frecuencia, se observa un líquido color ámbar o burbujas detrás del tímpano si se acumula líquido en el oído medio.

Se puede presentar una infección del oído externo si el conducto auditivo externo se torna rojo, sensible, inflamado y dolorido cuando se mueve o se hala el pabellón de la oreja, o si el conducto está lleno de pus de color verde amarillento.

Otras afecciones por las que puede realizarse el examen son:
