Jaw Augmentation is a cosmetic procedure performed with the aim to alter the appearance and structure of the jawline. The primary goal of this procedure is to improve facial harmony by creating a more balanced and defined jawline. Jaw Augmentation can be achieved through various surgical and non-surgical methods, such as Genioplasty, jaw implants, dermal fillers, and muscle relaxant injections. These techniques aim to improve issues such as a weak or receding chin, asymmetry, or disproportionate facial features.
Perth Specialist Plastic Surgeon Dr Guy Watts generally conducts orthognathic ‘jaw’ surgery as an inpatient procedure, utilising general anaesthesia. The duration of the operation depends on the specific surgical plan, which may involve additional procedures.
A well-defined jawline is considered an essential aspect of facial attractiveness for both men and women. A strong and balanced jawline contributes to the overall harmony of the face by providing support and proportion to other facial features, such as the nose, cheeks, and lips. It also plays a crucial role in establishing an individual’s facial profile.
To better understand what Jaw Augmentation is, we should first discuss jaw anatomy. The anatomy of the jaw comprises two primary bones, the mandible and maxilla. These are connected by a complex system of muscles, ligaments, and the temporomandibular joint, enabling the vital functions of chewing, speaking, and facial expressions.
The mandible, commonly known as the lower jaw, is the largest and strongest bone in the human face. It forms the lower part of the skull and connects to the skull at the temporomandibular joints, allowing for jaw movement.
The maxilla, or the upper jaw, is a paired bone that forms the central part of the facial skeleton. It is involved in the formation of the roof of the mouth, the floor and lateral walls of the nasal cavity, and the floor of the orbits.
The maxilla also contains the upper teeth and the maxillary sinuses, which are large air-filled cavities that contribute to the resonance of the voice. Together, the mandible and maxilla form the structure of the jaw and provide the framework for the soft tissues of the face.
The jaw serves essential functions in the human body, including mastication of food, articulation of speech, and expression of emotions, all of which are facilitated by its unique anatomical structure and intricate muscular system.
One of the primary functions of the jaw is to facilitate chewing and biting. The mandible and maxilla work together to enable the opening and closing of the mouth, allowing the teeth to break down food into smaller pieces. This process, known as mastication, is essential for proper digestion and nutrient absorption.
The jaw also plays a crucial role in speech production. The movement of the mandible and its interaction with the maxilla and other facial structures enable the formation of various speech sounds. Proper jaw function is necessary for clear and effective communication.
In addition to its functional roles, the jaw contributes to facial expressions, which are essential for non-verbal communication and social interactions. The shape and position of the jaw can influence emotions such as happiness, sadness, anger, and surprise.
There are different reasons why people resort to Jaw Augmentation surgery. Among them, we can mention:
Facial symmetry is often perceived as a key factor in attractiveness. Jaw Augmentation can help correct asymmetrical features by adjusting the size, shape, and position of the jaw. This can be achieved through various methods, such as implants, Genioplasty, or non-surgical procedures like dermal fillers.
A well-proportioned face is another important aspect of facial aesthetics. Jaw Augmentation can address issues such as a weak or receding chin, a prominent lower jaw, or a lack of definition in the jawline. By altering the structure of the jaw, these procedures can help create more balanced facial proportions and improve the overall harmony of facial features.
Some individuals may have congenital deformities affecting the jaw, such as micrognathia (small jaw), macrognathia (large jaw), or hemifacial microsomia (underdevelopment of one side of the face). Jaw procedures can help correct these deformities, improving both function and appearance.
Injuries to the jaw, such as fractures or dislocations, can lead to long-term issues with the jaw’s function and appearance. Jaw procedures can help restore the proper structure and function of the jaw, allowing for improved chewing, speech, and facial expressions.
Some individuals may experience complications or dissatisfaction with the results of previous surgeries or orthodontic treatments. Jaw Augmentation can help address these concerns by revising or supplementing previous treatments, ensuring a more satisfactory outcome and improved facial harmony.
Types of Jaw Augmentation procedures encompass both surgical and non-surgical approaches, such as implants, Genioplasty, and dermal fillers, each aimed at enhancing the shape, size, or projection of the jawline to achieve the desired aesthetic outcome.
Genioplasty, a surgical procedure that alters the chin’s position and shape, is usually performed under general anaesthesia. During the procedure,Dr Watts makes an incision either inside the mouth or under the chin to access the chin bone. The bone is then carefully cut and repositioned, sometimes with the help of metal plates and screws for stabilisation. The newly positioned chin bone is fixed in place, and the incision is closed with sutures.
Jaw angle implants are used to alter the width and definition of the lower jaw, creating a more pronounced and angular jawline. These implants are often made of biocompatible materials, such as silicone and are placed along the angle of the mandible through a small incision inside the mouth.
Custom jaw implants are designed specifically for each individual patient, taking into account their unique facial anatomy and aesthetic goals. These implants can address various issues, such as a weak chin, asymmetry, or lack of definition in the jawline. Custom jaw implants are made using 3-D computed tomography (CT) imaging and 3D printing technology, ensuring a precise fit and optimal results.
Orthognathic surgery is performed to correct significant jaw misalignment or malocclusion, often in conjunction with orthodontic treatment. This surgery can involve repositioning the upper jaw (maxilla), the lower jaw (mandible), or both, to improve the jaw’s function and appearance. Orthognathic surgery is more invasive than other Jaw Augmentation procedures and may require a longer recovery time.
Dermal fillers are injectable substances used to add volume and shape to the jawline without surgery. This non-surgical approach can be used to enhance the chin, jaw angle, or jawline contour, providing a temporary improvement in facial aesthetics. The effects of dermal fillers can last between 6 to 18 months, depending on the type of filler used.
Muscle relaxant injections can be used to slim the appearance of the jawline by relaxing the masseter muscles, which are responsible for jaw clenching and grinding. This non-surgical procedure can create a more refined and feminine jawline in patients with a square or overly muscular jaw. The effects of these injections can last between 3 to 6 months.
Fat grafting, also known as autologous fat transfer, involves harvesting fat from one area of the patient’s body, processing it, and then injecting it into the jawline to add volume and definition. This procedure offers a more natural and long-lasting alternative to dermal fillers, with results that can last several years.
Risks and benefits
Surgical Jaw Augmentation procedures generally provide more permanent and significant results compared to non-surgical procedures. However, surgery carries inherent risks, such as infection, anaesthesia complications, and scarring. Non-surgical procedures typically have fewer risks and a shorter recovery time, but the results are less dramatic and often temporary.
Recovery time
Recovery time for surgical Jaw Augmentation procedures can vary, ranging from a few weeks to several months, depending on the complexity of the surgery. Non-surgical procedures usually involve minimal to no downtime, with patients able to resume normal activities immediately or within a few days.
Costs
Surgical Jaw Augmentation procedures are generally more expensive than non-surgical alternatives due to factors such as; anaesthesia, facility fees, and the complexity of the procedure. However, surgical procedures often provide more permanent results, potentially reducing the need for future treatments.
Non-surgical procedures, while initially more affordable, may require repeated treatments to maintain the desired results, which can add up over time. It is essential for patients to weigh the costs, benefits, and their desired outcomes when deciding between surgical and non-surgical jaw augmentation options.
Before deciding on a Jaw Augmentation procedure, it is essential to have a clear understanding of your desired outcome. Consider factors such as the degree of change you want, the permanence of results, and your expectations for the procedure. This information can help you and Dr Watts determine the most appropriate approach for achieving your aesthetic goals.
Your overall health and medical history play a significant role in determining the right Jaw Augmentation procedure for you. Certain health conditions, medications, or previous surgeries may affect your eligibility for specific procedures or increase the risk of complications.
