Evaluation of Newborns with Preauricular Skin Lesions

摘要

What is the appropriate evaluation of a newborn with apparently isolated preauricular skin lesions (tags or pits)?Evidence-Based Answer All newborns should be screened for hearing loss, whether or not they have preauricular skin lesions. Newborns with these anomalies maybe at increased riskofhearing impairment. (Strength of Recommendation [SOR]: C, based on small observational studies and expert opinion.) Although there is a reported association between renal tract abnormalities and isolated preauricular skin lesions in infants, studies that have used renal ultra-sonography to evaluate these patients are inconclusive. Physicians should not perform renal imaging on newborns with preauricular skin lesions unless they have other congenital malformations. (SOR: C, based on small, observational, disease-oriented studies.)
