Introduction: The median mandibular cleft (MMC) is a rare craniofacial anomaly manifesting as a cleft of the lower lip and mandible, which may extend to the neck to a variable extent and severity. Its management involves a timely, staged, and multidisciplinary approach. Unlike for maxillary cleft lip and palate, the literature on this anomaly is scarce and scattered. Also, guidelines for the management of mandibular cleft are not clearly outlined. This narrative review aims to consolidate the prevalence, classification, pathophysiology, and management of MMC.
Materials and methods: A literature search was performed on PubMed, SCOPUS, and Web of Science for terms “Mandibular cleft” OR “Tessier 30.” From the preliminary search, n = 68 articles were hand-filtered as per relevance to MMC from the title and abstract.
Results: Among these articles, n = 56 were case reports, n = 2 were articles related to genetic associations, n = 4 syndromes associated, n = 3 discussed the classification of craniofacial clefts, and n = 3 were literature reviews. The findings from the literature are presented under subheadings embryonic origin, clinical presentation, diagnostic workup, and multidisciplinary management of MMC.
Conclusion: Traditionally, MMC was treated by multistep surgical procedures; however, the contemporary approach promotes early and single-step correction of both soft and hard tissue defects for better growth outcomes. These cases demand comprehensive workup and timely management. Newer innovations, such as the use of BMPs and resorbable reduction plates, need further validation.
