Aim: This study set out to look at the incidence of cleft lip and palate between siblings in the South Indian population
Materials and methods: Saveetha Dental College and Hospital's Oral & Maxillofacial Surgery Unit treated fifty cleft patients who also have siblings. The incidence of clefting in the family was researched using the history of consanguineous marriage.
Results: Eighty percent of patients had a cleft history, most commonly in younger siblings, while also there is an Increased incidence of the cleft with parents who have consanguineous marriage.
Conclusion: There is a strong correlation between CP and being related by blood. This study's findings on the frequency of consanguinity and the resulting heaviness of congenital disabilities highlight the critical importance of establishing a national registry for congenital anomalies such as craniofacial defects.
