Pinna anomalies associated with congenital conductive hearing loss

This paper compares the normal pinna with the abnormal congenitally malformed pinna. Then the abnormal pinna is related to case histories where a hearing loss was found due to a congenital malformation of the middle ear ossicles. Careful examination of the pinna, therefore, may be a simple diagnostic sign of an underlying potentially surgically correctable hearing loss. An abnormal pinna is more often associated with a middle ear anomaly than with any other congenital malformation including a urinary tract anomaly.
