Significance of Cleft lip
Cleft lip is a congenital condition marked by an incomplete fusion of the upper lip, leading to a split or opening that can occur alone or alongside cleft palate. It is relatively common, with a prevalence of 0.04 to 0.79 per 1000 live births. Cleft lip may result in oral hygiene challenges and an increased risk of periodontal disease. Additionally, factors such as maternal smoking during pregnancy are linked to its occurrence, making it a significant craniofacial deformity affecting newborns.
