On which side are cleft lips more commonly found?

Cleft lips are most commonly found on the left side of the face. This phenomenon can be attributed to several factors, including embryonic development and anatomical asymmetries that typically occur during the formation of facial structures.

The left-sided predominance has been observed in various studies, making it a consistent finding in the literature related to cleft lip prevalence. Ethnic variations and other factors may influence the overall rates of cleft lip occurrence, but the objective data tends to show a left-sided bias when it comes to their location.

In summary, understanding the anatomical and developmental reasons behind the left-side predominance helps clarify why the correct answer is that cleft lips are more commonly found on this side of the face.
