Understanding Orthognathic Surgery and Its Benefits

Orthognathic surgery is a medical procedure done to correct problems with the jaw bones. These problems may be present from birth or may develop over time due to injury, uneven growth, or other conditions. When the upper jaw, lower jaw, or both are not in the correct position, it can affect chewing, speaking, breathing, and facial appearance.

This surgery is usually recommended when braces alone cannot fix the problem. It is often done along with orthodontic treatment. The main goal of orthognathic surgery is to move the jaw bones into a better position so that the teeth fit properly and the face looks balanced.

Orthognathic surgery can help reduce jaw pain, improve bite problems, and make daily activities like eating and speaking easier. It is planned carefully using X-rays, scans, and dental models. The surgery is done under general anesthesia, so the patient is asleep during the procedure. Recovery takes time, but many patients notice long-term improvement in comfort and function.

Who May Need Orthognathic Surgery?

You may need orthognathic surgery if you have:

● Difficulty chewing or biting food

● Jaw pain or frequent headaches

● Trouble speaking clearly

● Severe overbite or underbite

● Open bite (front teeth do not touch)

● Facial imbalance or uneven jaw appearance

● Breathing problems, including sleep apnea

● Jaw problems that did not improve with braces

Types of Orthognathic Surgery

There are different types of orthognathic surgery depending on the jaw problem:

1. Upper Jaw Surgery (Maxillary Surgery)

This is done when the upper jaw is too forward, too backward, or uneven. The surgeon moves the upper jaw into a better position and fixes it with plates and screws.

2. Lower Jaw Surgery (Mandibular Surgery)

This is done when the lower jaw is too far forward or backward. The jaw is carefully moved and secured to improve bite and balance.

3. Double Jaw Surgery

Sometimes both upper and lower jaws need correction. This type is done when the jaw problem is more complex.

5. Chin Surgery (Genioplasty)

This may be done along with jaw surgery to improve chin shape and facial balance.

Orthognathic Surgery Procedure

Before surgery, the patient usually wears braces for several months to align the teeth. The surgeon and orthodontist plan the surgery together. Scans and images are used to decide how much the jaw should be moved.

On the day of surgery, the patient is given general anesthesia. The surgeon makes cuts inside the mouth, so there are usually no visible scars. The jaw bones are repositioned carefully and held in place using small metal plates and screws. These plates are safe and usually stay in place permanently.

The surgery can take several hours, depending on the type and complexity. After surgery, the patient stays in the hospital for monitoring. Swelling and discomfort are common in the first few days.

Recovery and Aftercare

Recovery from orthognathic surgery takes time and patience. Most swelling reduces within a few weeks, but full healing may take several months.

During early recovery:

● A liquid or soft food diet is required

● Pain and swelling are managed with medicines

● Good oral hygiene is very important

● Physical activity should be limited

Follow-up visits are needed to check healing. Braces may still be required for some time after surgery to fine-tune the bite. Most people return to normal daily activities within 4–6 weeks.

Risks and Possible Complications

Like all surgeries, orthognathic surgery has some risks. These may include:

● Infection

● Bleeding or swelling

● Temporary numbness in the lips or chin

● Nerve injury (rare but possible)

● Changes in bite position

● Need for additional treatment

Most complications are uncommon when surgery is done by experienced specialists and proper aftercare is followed.
