Methods
Our study included all infants born at Bnai-Zion Medical Center between January 1996 and December 1999. The cases of the our study consisted of healthy infants with isolated pre-auricular tags or pits. These infants were examined by a geneticist in search of other congenital anomalies. Family medical history was recorded for pre-auricular tags/pits and for hearing and renal abnormalities. Infants were excluded from the study if there were associated ear abnormalities or if other major
Results
During the study period, 17,286 infants were born in our institution. Pre-auricular tags and pits were detected in 110 infants. Two patients were excluded because of associated anomalies; one had a complex ear malformation composed of two left pre-auricular tags associated with right anotia and a father with anotia; the other had ventricular septal defect. Our cohort included 88 infants with pre-auricular tags and 20 infants with pre-auricular pits (a prevalence of 0.51% and 0.11%,
Discussion
Our study did not find a significant association between isolated pre-auricular tags or pits and urinary tract abnormalities. The incidence of isolated pre-auricular tags and pits found in our study (6.2/1000) is in accordance with other reports.1, 2, 3, 4, 5, 6 Thus, these defects are relatively common congenital anomalies, and recommendations for the appropriate evaluation for infants with these defects are warranted.
In the current study, only 2 infants of 92 infants with pre-auricular tags

2013, Seminars in PerinatologyCitation Excerpt :In most children with an isolated pit or tag, there are no other associated abnormalities. However, hearing loss may occur in some infants with isolated preauricular pits and tags, and testing of hearing has been recommended for these patients.16,17 There is controversy about whether there is an increased incidence of urinary tract abnormalities in infants with isolated preauricular pits and tags and whether renal ultrasound should be performed.17,18
