A child’s lower jaw may sometimes be comparatively undersized than the upper jaw. This condition is termed as Micrognathia. The growth of muscles would also be simultaneously affected as the bony structure is smaller than normal. This condition could also be associated with various syndromes (Pierre-Robin’s Syndrome, Treacher Collin’s Syndrome etc). As the lower jaw is small, the tongue gets pushed backwards and tends to block the air passage. Distraction Osteogenesis is an effective treatment option to lengthen the jaw size. By this procedure the jaw can be brought to the normal size, without the necessity of bone grafting (bone harvested from hip bone to lengthen the jaw size).
In some individuals, there may be an imbalance between right and left sides of the face. This type of facial growth deformity characterized by facial asymmetry is called Hemifacial Microsomia. In this condition, the structures of one side of the face grow lesser than the other side. This results in asymmetry of the face. The affected side of the face appears disproportionately smaller than the other. The commonly affected structures of this deformity are the lower jaw, eyes, ears, facial nerve and the cheeks. The most significant defect is that of the jaws, which when corrected, minimizes the entire deformity and makes the face look almost symmetric.
The best and most advanced treatment technique of reconstructive jaw surgery for facial asymmetry is Distraction Osteogenesis. Our hospital remains the only center till date in this part of the world to offer simultaneous Distraction Osteogenesis (Distraction of both upper and lower jaw) for the correction of facial asymmetries and has successfully rehabilitated the maximum number of patients afflicted with facial disfigurements in the country.
Facial bone deficiency or Hypoplasia can be corrected by bone grown by distraction. The asymmetry of the face that occurs due to lack of growth on one side of the face can be set right by “Simultaneous Maxillary and Mandibular Distraction”
