Background and Objectives Microtia-atresia is a rare congenital anomaly, which characterized by a small, abnormally shaped auricle (microtia) accompanied with narrow, blocked or absent ear canal (atresia). Microtia can occur appear either as independent clinical abnormality or as part of a syndrome. Due to hearing loss, 80%–90% of patients are at increasing risk of speech and poor academic performance. This abnormality with genetic predisposition and autosomal dominant or recessive mode of Mendelian hereditary, as well as forms due to chromosomal aberrations, occur in varying degrees from 0.83 to 17.4 per 10,000 births, usually unilateral form with more common in males. Case Presentation In this article, a term male neonate with microtia-atresia, born of a 34-year-old mother, was reported. On initial examination by a pediatrician, not properly formation of external right ear and absence of the ear canal was observed in infant. In a closer examination no craniofacial anomalies and no microtia associated syndrome was not observed.
