Tessier 30 Facial Cleft- Median Cleft of Upper and Lower Lip, Lower Alveolus and Mandible, Ankyloglossia and Cervical Teratoma

Cleft lip and palate are common, whereas median mandibular clefts are extremely rare anomaly found in cleft no. 30 in Tessier’s classification. This anomaly was first time reported by Couronne in 1819. So far upto 70 cases have been described in history.

Associated anomalies are lower lip hemangioma, facial anomalies, ankyloglossia, cleft palate, cervical dermoid cyst, hyoid bone agenesis, laryngeal cartilage malformation, epiglottis aplasia, cardiac malformation and chromosomal abnormalities, which further worsen the prognosis.

Failure of union of the first branchial arch in midline results in lower midline facial cleft defect whereas failure of fusion of the lower branchial arch elements are thought to lead to associated deformities of the neck.
