Abstract:

Duplication deformity in the oral and maxillofacial region is an extremely rare birth defect. Oral duplication demonstrates significant phenotype variation and must be managed with individualized protocol based on the extent of soft and bony tissue involvement and affected physiological functions. Here we report a case of oral duplication involving unilateral mandible and lower lip, with the deformity features and primary surgical treatment described and literature co-vering its etiology and management reviewed.

Key words: duplication anomaly, jaw, lower lip, birth defect, embryogenesis
