Background 

Orofacial clefting (OFC) is the most common developmental craniofacial malformation, and causal etiologies largely remain unknown. The opioid crisis has led to a large proportion of infants recovering from neonatal abstinence syndrome (NAS) due to in-utero narcotics exposure. We sought to characterize the prevalence of OFC in infants with NAS.

Methods 

This cohort study analyzed live births at our institution from 2013 to 2017 to identify any association between OFC and NAS.

Results 

Prevalence of OFC was 6.79 and 1.63 (per 1,000 live births) in the NAS and general population, respectively. Odds ratios for NAS patients having developed OFC, isolated cleft palate, isolated cleft lip, and combined cleft lip and palate compared with the general population were found to be 4.18 (P = 0.001), 5.92 (P = 0.001), 3.79 (P = 0.05), and 2.94 (P = 0.35), respectively. Analyses performed comparing the NAS and general populations to control for potential confounding variables influencing the NAS population yielded no significant differences with exception of in-utero exposure to physician prescribed opioids.

Conclusions 

Prevalence of OFC in infants with NAS was higher than the general live birth population. Isolated cleft palate and isolated cleft lip, specifically, were significantly more prevalent in NAS patients compared with the general population and were associated with in-utero opioid exposure.
