Abstract
OBJECTIVE: Cleft lip with or without cleft palate (CL±P) or cleft palate (CP) are groups of malformations named orofacial clefts (OC), which are the second leading cause of birth defects. This study aimed to analyze clinical and epidemiological features of Brazilian patients with OC, studying cases treated in the reference center of the state of Paraná (PR). METHODS: 2,356 charts were reviewed and 1,838 were evaluated by the same clinical geneticist. Data were collected in the reference center, and compared with those of the Health Department of the state of Paraná. Clinical characteristics, presence of other anomalies, and birth prevalence were evaluated. RESULTS: 389 (21.2%) patients had CP, 437 (23.8%) had cleft lip (CL), and 1,012 (55%) had cleft lip and palate (CLP). Syndromic OC were identified in 15.3% of patients, 10.4% of patients with CL±P, and 33.9% of patients with CP. Common additional anomalies were: central nervous system, limbs, cardiovascular, and musculoskeletal defects. The number of syndromic cases was lower when clinical evaluation was performed by other medical specialists when compared to that of the clinical geneticist. Birth prevalence was 1/1,010 live births. Lack of notification with the national birth registry was observed in 49.9% of CL±P. The present data suggests a decrease of 18.52% in the prevalence of non-syndromic OC after folic acid fortification in Brazil. CONCLUSION: Better understanding of clinical and epidemiological aspects of OC is crucial to improve the understanding of pathogenesis, promote preventive strategies, and guide clinical care, including the presence of clinical geneticists in the multidisciplinary team for OC treatment.
