Otology and Neurotology — Expert Reference

How it begins

El oído externo comprende el pabellón auricular (pinna) y el conducto auditivo externo (CAE) . La pinna está formada por cartílago elástico (excepto el lóbulo, adiposo) recubierto de pericondrio y piel; su función es la localización espacial del sonido por modificación espectral (función de transferencia relacionada con la cabeza, HRTF). El CAE mide ~2,5 cm en adultos: el tercio lateral es cartilaginoso y contiene…
