Genetically Weak Chin
According to the American Society of Plastic Surgeons, there are several reasons that a patient may complain about having "no chin." What they are referring to is the fact that they have a recessed chin, which makes their jawline appear weak.
Many people have weak chins due to genetic reasons. The person seeking guidance from a medical professional about correcting a recessed chin many times has experienced a deep overbite, where the chin was forced backwards. A weak chin profile may also be the result of certain medical conditions that cause patients to look as though they have double chins as the lower jaw sits in a position farther back from the upper jaw.
Despite the cause of the weakened chin, patients can seek solutions to improve their facial aesthetics via a board-certified plastic surgeon who specializes in chin surgery, or an orthodontist.
Recessed Chins and Newborns
There are times when a baby is born with a receding chin. The lower jaw bone of a fetus may form into a smaller size or stance in comparison to the upper jaw, causing it to slope backwards. This way, the infant might emerge with a receding chin that causes the lower lip to hang forward in a seemingly sulky state. Congenital conditions might be the cause of a newborn baby experiencing problems in the chin area.
Micrognathia is the term for a jaw that is smaller than normal. Although it is a relatively common condition in infants, micrognathia may correct itself over time. Other reasons for a small jaw forming in newborn babies include those related to hereditary traits passed down from parents, or due to medical syndromes.
Problems with the way the pregnancy develops, the positioning of the fetus in utero (with the baby's chin pressed again his or her chest), or other restricted growth, neurological, or connective tissue problems may also cause weak chins in newborns.
A Small Chin from An Overbite
Certain weak chins develop due to dental problems or jaw positions, such as when a person has an overbite. With a deep overbite, the chin is forced into a receded position in the direction of the individual's ears. The position of the lower jaw sitting back and away from the upper jaw can not only make the chin appear significantly smaller than normal, but it can also cause the afflicted person to appear to possess a double chin.
Fortunately, there are plenty of solutions to correct a weak chin, which ranges from receiving chin implants, orthodontic treatments, or chin surgery that directly affects the jawbone.
Surgery & Procedures: How to Fix a Small Chin
There are a variety of ways to correct a small chin, but the best option is based upon the patient's specific condition. Whereas some individuals may require orthodontic intervention, dermal filler injections in the chin periodically, or the placement of a chin implant to satisfy their chin profile needs, other conditions may necessitate surgical correction of the chin, which is called genioplasty.
Chin Augmentation with Implant
Chin implants are generally comprised of synthetic materials and are surgically implanted into the chin area as part of an outpatient procedure with general or local anesthesia. The process seeks to improve the facial aesthetics of a person with a small chin, although those that have a small jaw may benefit from genioplasty instead of a chin implant.
Knowledgeable plastic surgeons may recommend additional or alternative surgeries such as a facelift, neck lift, or rhinoplasty procedures for patients who have a recessed chin because a weak chin can make a person's nose appear larger.
Jaw Implants
Jaw implants, much like a chin implant, is the surgical placement of a synthetic material to permanently augment the jawline. For patients with a weak chin, the jawline may also need to be enhanced for a balanced profile.
Chin Augmentation with Fillers
Dermal fillers not only add volume to the lips, cheeks, and other areas of the face, they can also help improve facial proportions for people with weak chins. Juvederm Voluma® and Radiesse® are two common soft tissue fillers that can be used as a non-surgical chin augmentation option. The fillers that are injected into the soft tissues of the chin aren't permanent and require follow-up injections every 9-12 months. However, they can give patients a realistic view of how implants or surgery may enhance their appearance.
A fat transfer procedure using the patient’s body fat is another viable option as a chin augmentation filler. The fat that remains and isn’t lost due to reabsorption may last longer than other kinds of dermal fillers and provide more benefits (such as potential stem cell advantages) to the skin in the chin area.
Osseous Genioplasty
The chin surgery known as genioplasty involves incisions inside the lower lip to access and alter the lower jaw bone and chin. A small saw is used to cut the jaw bone and move it into an optimal position, attaching it to the jaw with screws and plates.
The results of the horizontal sliding genioplasty surgical procedure may take two to three months to realize after all swelling and bruising have subsided.
Dental Treatments
Braces can often fix a minor overbite that causes a receding chin, with an orthodontic treatment helping the chin to emerge as the overbite is corrected. Healthy teeth may simply be misaligned, with the "bad bite" causing problems such as weak chins, jaw pain, and headaches. Based on the individual situation, a better option for some patients may involve bringing the lower and upper teeth into better alignment to improve the chin's appearance. As with any procedure, the dentist will likely first take X-rays to determine the best course of action.
Relationship Between Chin & Nose Proportions
The appearance of the nose affects how the chin is perceived, and vice versa. A weak chin can make the nose appear longer and larger, leading people to believe they strictly need rhinoplasty surgery. However, afflicted patients may want to consider tandem procedures to address nose and chin problems simultaneously.
A small and receded chin can also make an individual appear to have jowls and a double chin. Since the size and positioning of the chin are vital to the nasal region proportions, it is important to keep the two facial features in close symmetry with one another. That’s why it is common for patients to undergo nose and chin alterations at the same time since they play so much off of each other.
