Abstract
Microtia-anotia (MA) describes a range of external ear anomalies which is commonly associated with various syndromes and malformations of the head and neck. Previous studies have suggested a strong association between MA and male sex, maternal diabetes, and Hispanic race/ethnicity. This study seeks to evaluate the associations between MA and preterm newborns in the United States. Population-based inpatient registry analysis was conducted. Kids' Inpatient Database (2016) was used to identify weighted in-hospital births with diagnosis of prematurity or MA. Demographic information was obtained, and odds ratios (ORs) were used to determine associations between prematurity and MA. Among patients included in our dataset, 8.655% (326 285) were preterm and 0.016% (523) had MA. 0.003% (109) of patients were preterm and had MA. Preterm infants had 2.19 times the odds (95% C.I. = 1.78-2.69) of having MA when compared to the full-term population. The binary logistic regression model accounting for possible confounding variables produced an aOR of 1.48 (95% C.I. = 1.17-1.87) for the association between prematurity and MA. Infants who are born preterm are more likely to have MA than full term infants. The current results will allow for improved risk stratification, maternal counseling, and interventions in the case of prematurity.
