Ear anomalies » Ear Q16 / Q17.9


In the newborn, in clinical practice and for the purpose of ICD10, all anomalies are of the external ear and it will not be known whether hearing is affected or not.
Differentiate malformation from deformity. In malformation there is missing or extra anatomical elements of the ear, while in deformity all relieves are normal, but deformed. During extra-uterine life some deformities may return to normality, but not the malformations.


Do not use vague nomenclatures, such as "dysplastic ears" or similar. Simply describe.


See the parameters of te normal ear in orer to fcilitate the precise desciption of ear anomalies.
