A survey of congenital heart disease in patients with oral clefts.

Abstract

The purpose of this study is to determine the prevalence of congenital heart disease in patients with cleft lip and/or palate. We undertook a retrospective study of 1148 cases, age < 15 years old, with cleft lip and/or palate from January 1991 to December 1998, of which congenital heart disease was associated in 62 patients. The overall prevalence of congenital heart disease in patients with clefts was 5.4%. Of the 62 patients, there were 38 boys and 24 girls. We classified clefts into one of three categories; group 1: cleft lip alone; group 2: cleft lip and palate; group 3: cleft palate alone. The cleft lip and palate (group 2) was present in the majority (27 of 62; 44%) of patients with congenital heart disease. Twenty-five patients (40%) had cleft palate, and ten patients (16%) had cleft lip. Isolated atrial septal defect and ventricular septal defect are the two common congenital defects, which presented 23% and 21% of patients, respectively. Apart from congenital heart disease and cleft lip or palate, 56% (35 of 62 patients) and additional abnormalities. Central nervous system and skeletal malformations were the most common associated abnormalities. In our study, congenital heart disease was more common in patients of group 2 and group 3 than of group 1. In addition, there was a significantly greater proportion of patients associated with other systemic anomalies in groups 2 and 3 than in group 1 (chi-square chi 2 = 7.535, p = 0.023), but no significant difference was noted between group 2 and group 3. We recommend that it would be appropriate for all cleft patients to receive a routine examination for associated anomalies by a pediatrician. With the widespread use of echocardiography and/or brain sonography, the early diagnosis and treatment of these anomalies are possible.
