Lower Jaw Retrusion

When the chin does not develop to normal/full size, it appears retruded or set back making the nose and eyes to look disproportionately large. This unequal jaw growth may be corrected with orthognathic surgery or distraction osteogenesis. Before deciding the line of treatment, a detailed assessment and analysis of the face & facial bones needs to be done.

Cosmetic orthognathic surgery is performed on the bone of the lower jaw. Portions of the jaw is cut, moved forward and stabilized in a more balanced position. The lower jaw and chin is more forwardly placed improving the appearance and profile. The surgery is performed inside the mouth so there is no scarring.

Balaji Dental and Craniofacial Hospital is among the best centers for jaw deformity correction and cosmetic jaw surgery by Orthognathic surgery and Distraction Osteogenesis.

Mandibular retrognathia, or lower jaw retrusion, is a condition characterized by the underdevelopment or backward positioning of the lower jawbone, resulting in a sunken appearance of the lower teeth and potential facial asymmetry. This stands in contrast to lower jaw protrusion, where the lower jaw extends excessively forward.

Causes of Mandibular Retrognathia:

1. Genetics: Hereditary factors indicate a potential genetic predisposition to the condition.
2. Childhood Habits: Tongue-tie and mouth breathing during childhood can influence jawbone growth, contributing to mandibular retrognathia.
3. Trauma: Injuries to the jaw or face in childhood may disrupt normal jawbone development and lead to retrusion.
4. Tumors: Abnormalities like tumors in the jaw or facial bones can interfere with normal jaw growth, resulting in retrusion.
5. Cleft Lip and Palate: Congenital conditions like cleft lip and palate can impact lower jaw development, causing retrusion.

Signs and Symptoms:

1. Sunken or recessed lower teeth, creating a flat facial profile.
2. Midfacial deficiency, contributing to facial asymmetry.
3. Overall facial asymmetry due to the underdeveloped lower jaw.
4. Difficulty breathing due to crowded nasal passages.
5. Increased risk of sleep apnea characterized by interrupted breathing during sleep.

Treatment for Mandibular Retrognathia:

1. Orthodontics: Mild to moderate cases may be addressed with orthodontic procedures, such as braces, gradually aligning teeth and jaws.
2. Orthognathic Surgery: Severe cases may require orthognathic surgery, involving the realignment of jawbones. Surgeons may move the lower jaw forward for a balanced facial profile.
3. Facial Implants: Implants can be used to augment the underdeveloped lower jaw, enhancing facial contour.
4. Soft Tissue Grafting: Techniques involving soft tissue grafts can improve midface symmetry.

Prevention Measures:

1. Addressing Childhood Habits: Early intervention for tongue-tie and promoting nasal breathing can support normal jaw development.
2. Prompt Treatment of Injuries: Timely medical attention for jaw or facial injuries minimizes the risk of long-term growth abnormalities.
3. Regular Dental Checkups: Routine dental checkups facilitate early detection and intervention if signs of mandibular retrognathia emerge.

Concerned individuals should consult an experienced dentist or oral and maxillofacial surgeon for a comprehensive evaluation and discussion of suitable treatment options tailored to individual needs.
