Left macrostomia was repaired using a W-plasty technique, and preauricular appendages were excised. The median defect of the mandible demonstrated by computed tomography scan on the first examination had disappeared at 1 year of age. Conclusion: Congenital clefts of the mandible can fuse at a later stage; thus, it is necessary to wait to treat the mandibular defect until the infant is slightly older.en10.1597/1545-1569(1999)036<0448:ALTFCW>2.3.CO;2info:eu-repo/semantics/closedAccessTransverse Facial CleftMedian Mandibular DefectLower LipArticle365448449Q2WOS:0000826213000102-s2.0-003283007410499407Q2
