In some instances, the growth of the condyle i.e. the component of the lower jaw forming a part of the TMJ may be affected. [/vc_column_text][vu_heading style=”2″ heading=”Micrognathia” subheading=”” alignment=”left” custom_colors=”” class=””][vc_column_text]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).[/vc_column_text][vu_heading style=”2″ heading=”Hemifacial Microsomia” subheading=”” alignment=”left” custom_colors=”” class=””][vc_column_text]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.
[/vc_column_text][vu_heading style=”2″ heading=”Surgical correction” subheading=”” alignment=”left” custom_colors=”” class=””][vc_column_text]Choice of treatment to correct growth defects of the TMJ depends on many factors including age of the patient, severity of the defect and other associated deformities present, if any.

Distraction Osteogenesis is the latest advanced and effective treatment option to lengthen the jaw length and correct facial asymmetry. 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).

On the deficient side of the face, the jaw bone is cut and the distractor device is fixed. The two arms of the device are fixed to the two cut segments of bone. After a few days, a screw attached to the device is turned which pushes the two bone segments apart. New bone is formed in the resultant gap and the jaw bone gradually lengthens. After the desired volume of bone is formed, the distractor device is removed.

Dr. S.M. Balaji’s expertise in distraction osteogenesis for correction of TMJ defects is exceptional and has met with great success.

Another treatment is by using a bone graft from the patient’s own rib (Costochondral graft). This may be commonly done to restore severely affected mandibular condyles in growing children. The bone graft is fixed to the existing deficient portion of the mandible (lower jaw bone) using wires or screws.[/vc_column_text][vu_heading style=”1″ heading=”Case I” subheading=”” alignment=”left” custom_colors=”” class=””][vc_row_inner equal_height=”” animation_delay=”” disable=”” id=”” class=””][vc_column_inner vertical_align=”top” animation_delay=”” width=”1/2″][vu_image_box image=”2674″ ratio=”2:1″ title=”CT scan image showing asymmetry of the facial skeleton” description=”” read_more_text=”Read More” link=”” class=””][/vc_column_inner][vc_column_inner vertical_align=”top” animation_delay=”” width=”1/2″][vu_image_box image=”2675″ ratio=”2:1″ title=”Distractor device being placed ” description=”” read_more_text=”Read More” link=”” class=””][/vc_column_inner][/vc_row_inner][vc_row_inner equal_height=”” animation_delay=”” disable=”” id=”” class=””][vc_column_inner vertical_align=”top” animation_delay=”” width=”1/2″][vu_image_box image=”2676″ ratio=”2:1″ title=”CT scan image showing progress of treatment” description=”” read_more_text=”Read More” link=”” class=””][/vc_column_inner][vc_column_inner vertical_align=”top” animation_delay=”” width=”1/2″][vu_image_box image=”2677″ ratio=”2:1″ title=”CT scan images before, during and after correction of facial asymmetry with distraction osteogenesis ” description=”” read_more_text=”Read More” link=”” class=””][/vc_column_inner][/vc_row_inner][vu_heading style=”1″ heading=”Case II” subheading=”” alignment=”left” custom_colors=”” class=””][vc_row_inner equal_height=”” animation_delay=”” disable=”” id=”” class=””][vc_column_inner vertical_align=”top” animation_delay=”” width=”1/3″][vu_image_box image=”2679″ ratio=”2:1″ title=”CT scan image showing facial asymmetry of the facial skeleton” description=”” read_more_text=”Read More” link=”” class=””][/vc_column_inner][vc_column_inner vertical_align=”top” animation_delay=”” width=”1/3″][vu_image_box image=”2680″ ratio=”2:1″ title=”Distractor being fixed” description=”” read_more_text=”Read More” link=”” class=””][/vc_column_inner][vc_column_inner vertical_align=”top” animation_delay=”” width=”1/3″][vu_image_box image=”2681″ ratio=”2:1″ title=”X-rays taken during start and end of distraction procedure” description=”” read_more_text=”Read More” link=”” class=””][/vc_column_inner][/vc_row_inner][vc_row_inner equal_height=”” animation_delay=”” disable=”” id=”” class=””][vc_column_inner vertical_align=”top” animation_delay=”” width=”1/3″][vu_image_box image=”2682″ ratio=”2:1″ title=”CT scan images before and after treatment, facial asymmetry corrected with distraction osteogenesis” description=”” read_more_text=”Read More” link=”” class=””][/vc_column_inner][vc_column_inner vertical_align=”top” animation_delay=”” width=”1/3″][vu_image_box image=”2683″ ratio=”2:1″ title=”During surgery-planning the distraction using sterolithographic model” description=”” read_more_text=”Read More” link=”” class=””][/vc_column_inner][vc_column_inner vertical_align=”top” animation_delay=”” width=”1/3″][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][/vc_section]
