Fixing the receeding chin

What is mandibular retrognathism?

Retrognathism is a facial condition in which the chin is retracted or positioned further back than normal in relation to the rest of the face. This condition may occur due to insufficient development of the mandibular bone or lower jaw. As a result, the facial profile may appear disproportionate, with a less prominent chin.

It is possible to correct retrognathism through a genioplasty (or mentoplasty, the chin surgery) or through a non-surgical procedure, such as filling with hyaluronic acid, which is a substance absorbable by the body that helps add volume to the chin.


Causes for retrognathism

Some possible causes of mandibular retrognathism include:

Genetic Factors: Genetic predisposition plays a significant role in the development of facial structures, including the jaw. If there is a family history of mandibular retrognathism, the condition is more likely to be inherited;

Facial Growth and Development: During facial development, uneven growth between the upper jaw and lower jaw can result in retrognathism. This discrepancy in growth can be influenced by several factors, including hormonal imbalances, bone growth patterns, and genetic influences;

Oral and Postural Habits: Certain inadequate oral and postural habits can affect the normal development of the jaw. For example, prolonged use of pacifiers, bottles or thumb sucking can put pressure on facial structures and affect jaw positioning;

Dental Malocclusion: The presence of a dental malocclusion, such as a crossbite or open bite, can influence the position of the jaw. Inadequate interaction between the upper and lower teeth can affect the growth and development of the jaw;

Facial Trauma: Traumatic injuries to the facial region, especially the jaw, can affect the position and development of the jaw;

Abnormal Jaw Development: Some medical conditions, such as Pierre Robin syndrome and Treacher Collins syndrome, are associated with abnormalities in the development of the jaw and mandible, which can result in mandibular retrognathism.


Treatment for retrognathism

With surgery

Receding chin correction surgery (mentoplasty) is carried out through incisions in the vestibule of the mouth (in the gums below the teeth), so that there are no visible scars. Silicone prostheses will be placed subcutaneously to give greater volume to the area.

It is also possible to correct mandibular retrognathism using fat grafts.


Without surgery

One of the least invasive and effective (although temporary) aesthetic treatments to resolve cases of retrognathism is the injection of hyaluronic acid into the chin. This solution achieves satisfactory results, but is not definitive. It lasts on average 6 to 8 months.
