Jaw Reduction Surgery: Causes, Symptoms, And Treatment

Jaw reduction surgery, also known as jaw contouring, reshapes the jawline to achieve a more balanced facial appearance. This procedure is often sought for cosmetic reasons to enhance facial harmony and improve self-confidence. The surgery involves modifying the bone structure of the jaw to create a slimmer and more refined look. 

If you are considering jaw reduction surgery, consult with a qualified plastic surgeon to discuss your goals and options. This procedure can help you achieve the facial aesthetics you desire, leading to a more confident and attractive appearance.

What Are the Symptoms of Jaw Reduction Surgery

Eating and speaking may be difficult in the initial days. Numbness and tightness in the jaw are common.  These symptoms usually subside gradually, and following post-operative care instructions can help in a smooth recovery process.  Contact your surgeon if you have concerns about your symptoms post-surgery.

  • Swelling and bruising around the jaw area are common after jaw reduction surgery, but these symptoms usually subside within a few weeks.
  • Pain or discomfort in the jaw may be experienced following the surgery, and your healthcare provider can recommend pain management strategies to help alleviate this.
  • Difficulty opening the mouth fully or chewing food may occur temporarily after jaw reduction surgery, but gentle exercises and a soft diet can help improve mobility.
  • Numbness or tingling sensation in the jaw and surrounding areas may be present due to nerve irritation during the procedure, but sensation typically returns gradually over time.
  • Changes in jaw function, such as limited range of motion or jaw clicking, could be noticeable after surgery, but these changes often improve as the healing process progresses.

Causes of Jaw Reduction Surgery

In some cases, conditions like bruxism or temporomandibular joint disorder can also lead to jaw enlargement.  This cosmetic procedure aims to sculpt the jawline for a more proportionate facial appearance and improved self-confidence.

  • Severe malocclusion, or misalignment of the teeth, can be a cause for jaw reduction surgery to improve the bite and overall oral health.
  • Temporomandibular joint (TMJ) disorder that results in chronic jaw pain and dysfunction may necessitate jaw reduction surgery as a treatment option.
  • Excessive growth of the jawbone, known as mandibular hyperplasia, can lead to a disproportionate facial appearance and may require surgical reduction.
  • Facial trauma or injury that results in a misshapen or asymmetrical jaw structure may be corrected through jaw reduction surgery.
  • Congenital conditions such as mandibular prognathism, where the lower jaw protrudes significantly, may be corrected through jaw reduction surgery to restore facial balance and improve functionality.

Types Of Jaw Reduction Surgery

Jaw reduction surgery typically involves two main types: mandibular angle reduction and masseter muscle reduction. Mandibular angle reduction focuses on reshaping the jawbone to create a slimmer appearance, while masseter muscle reduction involves reducing the size of the chewing muscles to achieve a more refined jawline. Both procedures are designed to improve facial proportions and enhance overall facial aesthetics.

  • Orthognathic surgery, also known as jaw surgery, is a procedure that can be performed to correct jaw alignment issues, reduce the size of the jaw, and improve facial symmetry.
  • Mandibular angle reduction surgery, commonly referred to as jaw contouring surgery, involves reshaping the lower jaw bone to create a more defined and slender jawline.
  • Genioplasty, or chin surgery, is a surgical procedure that can be performed to reduce the prominence of the chin, which can help balance the overall proportions of the face and achieve a more harmonious facial appearance.
  • Masseter muscle reduction surgery, also known as masseter reduction, involves reducing the size of the masseter muscles located in the jaw area, which can help soften a square or bulky jawline, leading to a more feminine or aesthetically balanced facial profile.

Risk Factors

Risk factors for jaw reduction surgery include infection, bleeding, nerve injury, scarring, and adverse reactions to anesthesia. Patients with certain medical conditions such as diabetes, high blood pressure, or a history of blood clotting disorders may be at higher risk for complications. It is important to discuss all potential risks with your surgeon before undergoing the procedure.

  • Individuals with a history of jaw fractures may be at higher risk for complications during jaw reduction surgery.
  • Patients who smoke are more likely to experience delayed healing and increased risk of infection following jaw reduction surgery.
  • Those with underlying medical conditions such as diabetes or autoimmune disorders may have a greater risk of surgical complications.
  • Poor oral hygiene can increase the risk of post-operative infections and negatively impact the healing process after jaw reduction surgery.
  • Patients who have unrealistic expectations or psychological concerns about their appearance may be at a higher risk for dissatisfaction or emotional distress following jaw reduction surgery.

Diagnosis of Jaw Reduction Surgery

The surgeon will conduct a physical examination, review your medical history, and may use imaging tests like X-rays or CT scans to assess the jaw structure.  Based on this evaluation, the surgeon will determine if jaw reduction surgery is a suitable option for achieving your cosmetic goals.

  • Physical examination: A thorough assessment of the patient's jaw structure, alignment, and range of motion is conducted by the surgeon to determine the need for jaw reduction surgery.
  • Medical history review: Understanding the patient's medical history, including past surgeries, injuries, and conditions that may impact the jaw, is essential for planning the surgical procedure effectively.
  • Imaging tests: X-rays, CT scans, and MRI scans can provide detailed images of the jawbone, teeth, and surrounding structures to evaluate the extent of jaw enlargement and plan the surgical approach accordingly.
  • Dental evaluation: An examination of the teeth and bite alignment helps assess how the jaw size contributes to any bite abnormalities or functional issues that may require correction during jaw reduction.

Treatment for Jaw Reduction Surgery

Treatment options for jaw reduction surgery include surgical procedures like mandibular angle reduction and masseter muscle reduction. These surgeries involve reshaping the jawbone or reducing the size of the jaw muscles to achieve a more balanced facial appearance. 

Non-surgical options such as Botox injections can also be considered to temporarily reduce the size of the jaw muscles. Consulting with a qualified surgeon will help determine the best treatment approach for individual needs.

  • Surgical resection of the masseter muscle is a common treatment option for jaw reduction surgery, where the muscle is trimmed to reduce its size and prominence.
  • Botox injections can be used to temporarily weaken the masseter muscle, leading to a slimmer jawline, although results are not permanent and require repeated treatments.
  • Orthodontic treatments such as braces or clear aligners can help align the teeth and jaws, which may improve the overall appearance of the jawline and reduce the need for surgical intervention.
  • Liposuction of the lower face and jaw area can be performed to remove excess fat deposits, resulting in a more defined and sculpted jawline.
