Mandibular protrusion correction surgery

Short-Term Effects

In the immediate period after surgery, patients typically experience noticeable facial swelling, along with possible pain and bruising. Generally, within 1 to 2 weeks post-operation, the swelling gradually subsides and pain diminishes, allowing for an initial view of changes in facial contour.

Long-Term Effects

Over time, as swelling fully resolves and bone healing completes, a more stable outcome is usually visible within 3 to 6 months after surgery. Protrusion of the lower jaw is significantly improved, facial lines become smoother, facial proportions more balanced, and bite function also sees a degree of improvement.

The following groups are suitable for genioplasty to correct mandibular protrusion:

• Individuals with excessive mandibular protrusion causing facial proportion imbalance and aesthetic concerns.
• Individuals with occlusal dysfunction, such as Class III malocclusion (underbite), affecting chewing and oral health.
• Individuals experiencing significant psychological stress due to mandibular protrusion, with a strong desire for improvement and stable mental health.

However, the following conditions are contraindications for this surgery:

• Patients with severe systemic diseases, such as heart disease, hypertension, or diabetes, who cannot tolerate surgery.
• Individuals with active oral infections, such as periodontitis or gingivitis, that are not effectively controlled.
• Pregnant or breastfeeding women.
• Individuals with unstable mental health or unrealistic expectations regarding surgical outcomes.

Price

The price of mandibular protrusion correction surgery varies depending on multiple factors, typically ranging from approximately 20,000 to 67,000 USD (converted from 300,000 to 1,000,000 KRW). The main factors influencing the price include:

• Surgical method: Different surgical techniques vary in difficulty and complexity, leading to price differences. For instance, sagittal split ramus osteotomy is relatively complex and may carry a higher cost.
• Hospital and surgeon: Large tertiary hospitals and experienced surgeons typically charge higher fees due to their advanced equipment, specialized expertise, and extensive clinical experience.
• Region: Economic development and living costs differ across regions, affecting surgical pricing. Generally, prices in major metropolitan areas are higher than in second- or third-tier cities.

Expected Outcomes

Patients should have realistic expectations regarding the results of mandibular protrusion correction surgery. The procedure can significantly improve mandibular protrusion, enhance facial contour aesthetics, and provide a degree of improvement in occlusal function. However, surgical outcomes are influenced by multiple factors, including the patient's individual characteristics, the surgical technique employed, and the surgeon's expertise. Therefore, patients should engage in thorough preoperative consultations with their surgeon to understand the potential results and avoid developing unrealistic expectations.

Combined Therapy

Orthodontic Treatment: Orthognathic surgery for mandibular protrusion is typically accompanied by orthodontic treatment both before and after the procedure. Pre-surgical orthodontics adjusts tooth alignment to create optimal conditions for surgery, while post-surgical orthodontics helps consolidate surgical outcomes, further refine occlusion, and achieve more uniform tooth alignment.

Facial Plastic Surgery: For patients with overall facial disharmony, mandibular protrusion correction can be performed in conjunction with other facial plastic procedures, such as rhinoplasty or genioplasty, to achieve more ideal aesthetic results.

Side Effects and Complications

- Bleeding and Hematoma: Bleeding may occur during the surgery. If hemostasis is not complete, a hematoma may form postoperatively. This is typically managed through pressure application, drainage, and other methods.

- Infection: If the surgical incision becomes infected, it may cause local redness, swelling, pain, and fever. Antibiotics are used postoperatively to prevent infection. If infection occurs, anti-infective treatment should be initiated immediately.

- Nerve Damage: The area around the mandible contains numerous nerves that may be damaged during surgery, leading to symptoms such as numbness of the lower lip and paresthesia. Most nerve injuries are temporary and gradually recover postoperatively, although a small number of cases may result in permanent nerve damage.

- Poor Bone Healing: Postoperatively, the bone may heal improperly, affecting the stability of the mandible. This can be related to the patient's individual condition, surgical technique, postoperative care, and other factors. Appropriate measures, such as extending fixation time or performing revision surgery, may be required depending on the specific situation.

- Swelling and Bruising: Facial swelling and bruising are common side effects after surgery and typically subside within 1 to 2 weeks postoperatively.

- Scarring: Surgical incisions may leave some scarring. However, surgeons usually select concealed incision sites, such as intraoral incisions, to minimize the aesthetic impact of scars. For most patients, scars gradually fade over time, although a small number of patients may experience hypertrophic scarring.

Select Equipment

In addition to the CT scanners and surgical instruments mentioned earlier, the following equipment may also be considered:

- Digital Simulation System: Some advanced medical facilities utilize digital simulation systems that can simulate surgical procedures and postoperative outcomes based on a patient's CT data on a computer. This allows patients to visually understand the potential results before surgery and also assists doctors in formulating more precise surgical plans.

- Ultrasonic Bone Scalpel: The ultrasonic bone scalpel uses ultrasonic energy for bone cutting. It offers advantages such as high cutting precision and minimal damage to surrounding tissues, helping to reduce postoperative complications while ensuring effective surgical outcomes.

Contraindications for the Procedure

As previously mentioned, contraindications for the procedure include severe systemic diseases, uncontrolled local oral infections, pregnancy or breastfeeding, and psychological instability. Additionally, patients who have recently taken medications that affect blood clotting, such as aspirin, and have not discontinued them for a sufficient duration, are not suitable candidates for surgery, as this may increase the risk of surgical bleeding.

Individuals with a history of psychiatric disorders or those currently taking psychiatric medications may experience reduced tolerance to surgery and delayed postoperative recovery. In such cases, the decision to proceed with surgery should be made only after the condition is effectively managed and a thorough evaluation by a physician confirms suitability.

Side Effects and Complications

Hemorrhage and Hematoma: Bleeding may occur during surgery; if hemostasis is incomplete, a hematoma may form postoperatively. This is typically managed through compression, drainage, and other methods.

Infection: If the surgical incision becomes infected, it may cause local redness, swelling, pain, and fever. Antibiotics are prescribed postoperatively to prevent infection; if infection occurs, prompt anti-infective treatment is necessary.

Nerve Injury: The area surrounding the mandible is rich in nerve supply, and these nerves may be inadvertently damaged during surgery, leading to symptoms such as numbness or paresthesia of the lower lip. Most nerve injuries are temporary and gradually recover after surgery, though rare cases may result in permanent nerve damage.

Poor Bone Healing: Postoperatively, the bone may heal improperly, affecting the stability of the mandible. This can be influenced by patient-specific factors, surgical technique, and postoperative care. Management may involve extending fixation time or performing revision surgery, depending on the specific situation.

Side Effects

Swelling and Bruising: Facial swelling and bruising are common side effects after surgery and typically subside within 1–2 weeks postoperatively.

Scarring: Surgical incisions may leave visible scars; however, surgeons often choose discreet incision sites, such as intraoral approaches, to minimize aesthetic impact. In most patients, scars fade gradually over time, though a minority may develop hypertrophic scarring.

Self-Diagnosis of Symptoms

If you notice the following symptoms, it may indicate a prominent lower jaw:

- Facial appearance: From the side, the lower jaw protrudes significantly, resulting in an unbalanced facial profile with an underbite appearance.

- Occlusion: When the upper and lower teeth meet, the lower front teeth overlap the upper front teeth, making normal chewing and biting difficult.

- Chewing function: You may experience difficulty chewing or reduced chewing efficiency, which can negatively affect digestion over time.

Select Treatment Plan

Doctors will develop a personalized treatment plan based on the patient's specific condition, primarily considering the following factors:

- Degree of mandibular protrusion: Mild mandibular protrusion may be corrected through orthodontic treatment or relatively simple surgical procedures, whereas severe cases may require more complex surgical methods.

- Patient's age and skeletal development: For adolescent patients, since the skeleton is still developing, orthodontic intervention may be used first to guide normal skeletal growth. In contrast, for adults whose skeletal development has matured, surgical correction is typically necessary.

- Occlusal function: If occlusal dysfunction is severe, the surgical plan must prioritize improving occlusal relationships to enhance chewing function and oral health.

- Patient's age and skeletal development: For adolescent patients, since the skeleton is still developing, orthodontic intervention may be used first to guide normal skeletal growth. In contrast, for adults whose skeletal development has matured, surgical correction is typically necessary.

- Occlusal function: If occlusal dysfunction is severe, the surgical plan must prioritize improving occlusal relationships to enhance chewing function and oral health.

Short-Term Effects

In the immediate period after surgery, patients typically experience noticeable facial swelling, along with possible pain and bruising. Generally, within 1 to 2 weeks post-operation, the swelling gradually subsides and pain diminishes, allowing for an initial view of changes in facial contour.

Long-Term Effects

Over time, as swelling fully resolves and bone healing completes, a more stable outcome is usually visible within 3 to 6 months after surgery. Protrusion of the lower jaw is significantly improved, facial lines become smoother, facial proportions more balanced, and bite function also sees a degree of improvement.

The following groups are suitable for genioplasty to correct mandibular protrusion:

• Individuals with excessive mandibular protrusion causing facial proportion imbalance and aesthetic concerns.
• Individuals with occlusal dysfunction, such as Class III malocclusion (underbite), affecting chewing and oral health.
• Individuals experiencing significant psychological stress due to mandibular protrusion, with a strong desire for improvement and stable mental health.

However, the following conditions are contraindications for this surgery:

• Patients with severe systemic diseases, such as heart disease, hypertension, or diabetes, who cannot tolerate surgery.
• Individuals with active oral infections, such as periodontitis or gingivitis, that are not effectively controlled.
• Pregnant or breastfeeding women.
• Individuals with unstable mental health or unrealistic expectations regarding surgical outcomes.

Price

The price of mandibular protrusion correction surgery varies depending on multiple factors, typically ranging from approximately 20,000 to 67,000 USD (converted from 300,000 to 1,000,000 KRW). The main factors influencing the price include:

• Surgical method: Different surgical techniques vary in difficulty and complexity, leading to price differences. For instance, sagittal split ramus osteotomy is relatively complex and may carry a higher cost.
• Hospital and surgeon: Large tertiary hospitals and experienced surgeons typically charge higher fees due to their advanced equipment, specialized expertise, and extensive clinical experience.
• Region: Economic development and living costs differ across regions, affecting surgical pricing. Generally, prices in major metropolitan areas are higher than in second- or third-tier cities.

Expected Outcomes

Patients should have realistic expectations regarding the results of mandibular protrusion correction surgery. The procedure can significantly improve mandibular protrusion, enhance facial contour aesthetics, and provide a degree of improvement in occlusal function. However, surgical outcomes are influenced by multiple factors, including the patient's individual characteristics, the surgical technique employed, and the surgeon's expertise. Therefore, patients should engage in thorough preoperative consultations with their surgeon to understand the potential results and avoid developing unrealistic expectations.

Combined Therapy

Orthodontic Treatment: Orthognathic surgery for mandibular protrusion is typically accompanied by orthodontic treatment both before and after the procedure. Pre-surgical orthodontics adjusts tooth alignment to create optimal conditions for surgery, while post-surgical orthodontics helps consolidate surgical outcomes, further refine occlusion, and achieve more uniform tooth alignment.

Facial Plastic Surgery: For patients with overall facial disharmony, mandibular protrusion correction can be performed in conjunction with other facial plastic procedures, such as rhinoplasty or genioplasty, to achieve more ideal aesthetic results.

Side Effects and Complications

- Bleeding and Hematoma: Bleeding may occur during the surgery. If hemostasis is not complete, a hematoma may form postoperatively. This is typically managed through pressure application, drainage, and other methods.

- Infection: If the surgical incision becomes infected, it may cause local redness, swelling, pain, and fever. Antibiotics are used postoperatively to prevent infection. If infection occurs, anti-infective treatment should be initiated immediately.

- Nerve Damage: The area around the mandible contains numerous nerves that may be damaged during surgery, leading to symptoms such as numbness of the lower lip and paresthesia. Most nerve injuries are temporary and gradually recover postoperatively, although a small number of cases may result in permanent nerve damage.

- Poor Bone Healing: Postoperatively, the bone may heal improperly, affecting the stability of the mandible. This can be related to the patient's individual condition, surgical technique, postoperative care, and other factors. Appropriate measures, such as extending fixation time or performing revision surgery, may be required depending on the specific situation.

- Swelling and Bruising: Facial swelling and bruising are common side effects after surgery and typically subside within 1 to 2 weeks postoperatively.

- Scarring: Surgical incisions may leave some scarring. However, surgeons usually select concealed incision sites, such as intraoral incisions, to minimize the aesthetic impact of scars. For most patients, scars gradually fade over time, although a small number of patients may experience hypertrophic scarring.

Select Equipment

In addition to the CT scanners and surgical instruments mentioned earlier, the following equipment may also be considered:

- Digital Simulation System: Some advanced medical facilities utilize digital simulation systems that can simulate surgical procedures and postoperative outcomes based on a patient's CT data on a computer. This allows patients to visually understand the potential results before surgery and also assists doctors in formulating more precise surgical plans.

- Ultrasonic Bone Scalpel: The ultrasonic bone scalpel uses ultrasonic energy for bone cutting. It offers advantages such as high cutting precision and minimal damage to surrounding tissues, helping to reduce postoperative complications while ensuring effective surgical outcomes.

Contraindications for the Procedure

As previously mentioned, contraindications for the procedure include severe systemic diseases, uncontrolled local oral infections, pregnancy or breastfeeding, and psychological instability. Additionally, patients who have recently taken medications that affect blood clotting, such as aspirin, and have not discontinued them for a sufficient duration, are not suitable candidates for surgery, as this may increase the risk of surgical bleeding.

Individuals with a history of psychiatric disorders or those currently taking psychiatric medications may experience reduced tolerance to surgery and delayed postoperative recovery. In such cases, the decision to proceed with surgery should be made only after the condition is effectively managed and a thorough evaluation by a physician confirms suitability.

Side Effects and Complications

Hemorrhage and Hematoma: Bleeding may occur during surgery; if hemostasis is incomplete, a hematoma may form postoperatively. This is typically managed through compression, drainage, and other methods.

Infection: If the surgical incision becomes infected, it may cause local redness, swelling, pain, and fever. Antibiotics are prescribed postoperatively to prevent infection; if infection occurs, prompt anti-infective treatment is necessary.

Nerve Injury: The area surrounding the mandible is rich in nerve supply, and these nerves may be inadvertently damaged during surgery, leading to symptoms such as numbness or paresthesia of the lower lip. Most nerve injuries are temporary and gradually recover after surgery, though rare cases may result in permanent nerve damage.

Poor Bone Healing: Postoperatively, the bone may heal improperly, affecting the stability of the mandible. This can be influenced by patient-specific factors, surgical technique, and postoperative care. Management may involve extending fixation time or performing revision surgery, depending on the specific situation.

Side Effects

Swelling and Bruising: Facial swelling and bruising are common side effects after surgery and typically subside within 1–2 weeks postoperatively.

Scarring: Surgical incisions may leave visible scars; however, surgeons often choose discreet incision sites, such as intraoral approaches, to minimize aesthetic impact. In most patients, scars fade gradually over time, though a minority may develop hypertrophic scarring.

Self-Diagnosis of Symptoms

If you notice the following symptoms, it may indicate a prominent lower jaw:

- Facial appearance: From the side, the lower jaw protrudes significantly, resulting in an unbalanced facial profile with an underbite appearance.

- Occlusion: When the upper and lower teeth meet, the lower front teeth overlap the upper front teeth, making normal chewing and biting difficult.

- Chewing function: You may experience difficulty chewing or reduced chewing efficiency, which can negatively affect digestion over time.

Select Treatment Plan

Doctors will develop a personalized treatment plan based on the patient's specific condition, primarily considering the following factors:

- Degree of mandibular protrusion: Mild mandibular protrusion may be corrected through orthodontic treatment or relatively simple surgical procedures, whereas severe cases may require more complex surgical methods.

- Patient's age and skeletal development: For adolescent patients, since the skeleton is still developing, orthodontic intervention may be used first to guide normal skeletal growth. In contrast, for adults whose skeletal development has matured, surgical correction is typically necessary.

- Occlusal function: If occlusal dysfunction is severe, the surgical plan must prioritize improving occlusal relationships to enhance chewing function and oral health.
