Congenital Partial Hypoplasia of the Lower Lip: A Rare Form of 28-29 Tessier Cleft? Report of a Case.

We aim to describe a case of congenital partial hypoplasia of the lower lip in a 2-year-old child. The presence of a gingival notch, a mucosal bridle, and difficulties with tooth eruption raised the possibility of a modified 28-29 Tessier cleft. However, other hypotheses have been proposed as the anomaly does not conform to standard cleft anatomical findings.
