TMJ Growth Defects

TMJ Growth Defects

Some persons, by birth, may be affected by disorders of the TMJ. 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.


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).

Hemifacial Microsomia

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.

Surgical Correction of TMJ Growth Defects at Dr. S.M. Balaji

The temporomandibular joint (TMJ) plays a crucial role in our ability to chew, speak, and yawn. Growth defects of the TMJ can lead to facial asymmetry, difficulty chewing, and even pain. Dr. S.M. Balaji, a renowned maxillofacial surgeon, offers a range of surgical techniques to correct TMJ growth defects and restore facial harmony.

Distraction Osteogenesis: A Revolutionary Approach

For cases requiring jaw lengthening, Dr. Balaji employs distraction osteogenesis, a cutting-edge technique that eliminates the need for bone grafting. This procedure involves cutting the jawbone and implanting a distractor device. Over time, the device gradually separates the bone segments, allowing new bone formation to fill the gap. Once sufficient bone growth has occurred, the distractor device is removed, leaving behind a lengthened jawbone and a restored facial balance.

Costochondral Graft: A Time-Tested Technique

For severe condylar defects in growing children, Dr. Balaji utilizes the costochondral graft technique. This procedure involves harvesting a portion of the patient’s rib bone, including cartilage, and grafting it onto the deficient area of the mandible. The cartilage promotes bone growth, effectively restoring the jawbone’s structure and function.
