2 Of these 12 infants, 11 (92 percent) had multiple congenital anomalies, whereas only one (8 percent) had an isolated ear defect. 6 A retrospective chart review of 42 infants with ear anomalies who had renal ultrasonography found that 12 (29 percent) had concomitant renal abnormalities. Some of the treatment options that are considered for vaginal skin tags include: Cryotherapy: involves freezing the skin tag with liquid nitrogen. There are early warning signs for vaginal infection in newborn girls to help parents quickly detect the disease and treat it promptly such as: vaginal. 5 In contrast, one study of 70 newborns with isolated preauricular skin tags and a comparison group of 69 newborns with no preauricular lesions found a statistically significant increased risk of urinary tract abnormalities in those with lesions (8.6 versus 0.0 percent P <. 4 The largest study, which involved 100 newborns with isolated preauricular tags and a control group of 100 paired infants, supported these findings the prevalence of renal abnormalities was 2 percent in both groups.

1 A prospective study involving 92 infants also found no statistically significant difference in the prevalence of renal abnormalities in those with preauricular lesions compared with infants in the control group (2.2 versus 3.1 percent). In the prospective study above, findings from renal ultrasonography performed on infants with preauricular lesions were normal. Evidence on the relationship between isolated preauricular lesions and renal abnormalities (e.g., renal agenesis, cystic kidney disease, hydronephrosis, duplicated ureters, megaureter, vesiculoureter reflux) is conflicting.
