Nilüfer Orthognathic Surgery (Jaw Surgery): A Guide to the Process and Recovery

Nilüfer Orthognathic Surgery (Jaw Surgery): Rebuilding Function and Anatomical Harmony

A healthy oral structure is not made up of properly aligned teeth alone. The lower and upper jaw bones that support the teeth must be in harmony with each other and with the rest of the face in three dimensions for vital functions such as chewing, speaking, and breathing to work properly. When the jawbones are not in their ideal positions due to developmental or genetic reasons, this not only creates aesthetic concerns; it also paves the way for digestive problems, joint disorders, and serious respiratory issues such as sleep apnea. Orthognathic surgery (jaw surgery) procedures carried out in clinics and fully equipped healthcare facilities in Bursa Nilüfer aim to permanently correct these skeletal discrepancies. In this guide, what orthognathic surgery is, who it is performed on, and how the treatment stages progress are discussed in light of medical data.

What Is Orthognathic Surgery?

Etymologically, orthognathic surgery, formed from the combination of the words “ortho” (straight, correct) and “gnathic” (jaw), covers all surgical interventions performed to correct skeletal deformities in the jawbones. This treatment is never a standalone surgical process; it is a multidisciplinary treatment carried out side by side for years by the orthodontist and the oral and maxillofacial surgeon.

Traditional orthodontic treatments using braces alone can solve crowding by moving the teeth within the bone. However, if the problem is not in the teeth but in the bone that supports them (for example, if the lower jaw is much longer than normal or the upper jaw is too far back), braces alone are not strong enough to move the bone. At this point, orthognathic surgery comes into play, allowing the bones to be surgically moved to the planned ideal positions and fixed there.

In Which Skeletal Conditions Is Jaw Surgery Used?

Discrepancies in the jawbones usually become more noticeable during adolescence, during the growth spurt. Although bone guidance can be partially achieved with special appliances in patients during growth and development, surgical intervention is the only way to make skeletal corrections in adults whose growth plates have closed (generally 18 years and older). The main conditions for which orthognathic surgery is indicated are as follows:

Lower Jaw Protrusion (Prognathism): This is when the lower jawbone develops excessively and moves in front of the upper jaw. The front teeth bite in reverse, and biting function is significantly impaired.
Lower Jaw Retraction (Retrognathism): This is the backward positioning of the lower jaw as a result of insufficient growth of the lower jaw or excessive growth of the upper jaw. From the side, the lower lip appears receded, and this usually narrows the airway, leading to snoring or sleep apnea.
Open Bite: This is when a noticeable gap remains between the front teeth while the back teeth are in contact. Patients cannot tear any food with their front teeth, and the tongue constantly enters this gap, causing lisping.
Jaw Asymmetry: This is when the jawbone grows by shifting to the right or left, creating a noticeable distortion in the midline of the face.
Gummy Smile: This is when the upper jawbone is vertically drooped more than normal, causing the gums to be excessively visible when the patient smiles or speaks.

After the bones are brought to their ideal positions through surgical intervention, small titanium plates and screws are used, as seen in the anatomical model above, to maintain the new position and ensure bone healing. These fixators are fully compatible with the tissue and can remain in the body for life.

Treatment Process: The Collaboration of Orthodontics and Surgery

Orthognathic surgery is a long-term treatment that requires patience. Although the process varies depending on the patient’s anatomical structure and tissue response, it generally progresses through the following four main stages:

1. Comprehensive Analysis and Virtual Surgical Planning

The success of the treatment depends on millimeter-level measurements taken before surgery. Three-dimensional jaw tomography scans (CBCT), cephalometric X-rays, and intraoral digital scans taken in well-equipped clinics in the Nilüfer area are combined to create a virtual copy of the patient. The surgeon and orthodontist perform the surgery virtually using special software. At this stage, it is finalized at which millimeter and at which angle the bones will be cut and advanced or set back.

2. Pre-Surgical (Decompensation) Orthodontics

In individuals with skeletal discrepancies, teeth naturally tilt at incorrect angles in an effort to make chewing possible and close the gap. When the surgeon brings the bones to the correct position, these teeth must first be returned to their “ideal” angles within their own bones so they can fit together perfectly. In this stage, called decompensation, the patient wears braces. The process usually takes 1 to 1.5 years. The most notable feature of this period is that as the teeth are corrected within their own bones, the skeletal discrepancy becomes even more visually pronounced. This is completely expected and necessary to prepare for surgery.

3. Surgical Stage (Operation)

When the teeth have reached the desired position, the surgical stage begins. The procedure is performed under general anesthesia in a fully equipped hospital setting. Depending on the number of jaws to be treated (single jaw or double jaw), the operation lasts between 2 and 5 hours. One of the most important features of the surgery is that all incisions are made inside the mouth. This means there are no visible scars or stitches on the face from the outside. The jawbones are released from the anatomical lines using special ultrasonic devices or fine saws (osteotomy), moved to the planned new position, and fixed in that new position with titanium plates and screws.

4. Post-Surgical Fine-Tuning Orthodontics

After bone healing is largely complete (approximately 4-6 weeks after surgery), the orthodontist steps in to make millimetric fine adjustments to the bite. This final stage, which ensures the chewing plane settles properly, usually continues for about 6 months, after which the braces are completely removed and the treatment is concluded.

What Should Be Expected During Recovery?

As with any surgical intervention, orthognathic surgery has recovery dynamics that vary from patient to patient. However, the generally accepted process is as follows:

Swelling and Edema: The first 72 hours after surgery are the period when edema is most intense. Noticeable swelling in the face and sometimes bruising is a physiological tissue response. Starting from the third day, the edema begins to subside rapidly; it takes about 3-4 weeks for the face to return to its normal contours.
Pain Management: Since there is no dense nerve network inside the jawbone, the pain is not as severe as feared despite the bone cuts. During the hospital stay (usually 1-2 nights), the process is managed comfortably with painkillers given intravenously, and after discharge, with oral painkillers.
Eating Discipline: The most challenging part of the recovery process is eating. To avoid risking bone healing, chewing is strictly prohibited for the first few weeks. Patients spend this period with clear liquids, smooth soups, special nutritional formulas, and fruit juices. In the following weeks, under the doctor’s supervision, they gradually transition to pureed soft foods and then to a normal diet.
Numbness: Especially after lower jaw surgery, temporary numbness in the lip and chin area is quite normal. The nerve endings may take several months, and in some cases up to a year, to recover.

Conclusion: Why Undergo This Process?

Orthognathic surgery is not a plastic surgery operation performed solely for aesthetic concerns; its main purpose is to restore lost chewing, breathing, and speaking functions to the system. Proper jaw closure makes the first step of the digestive system healthy, while bringing the lower jaw forward expands the airway and dramatically improves sleep quality. Alongside all these functional gains, achieving skeletal harmony in the facial profile creates a very noticeable and positive change in the patient’s facial aesthetics. Thanks to the advanced treatment infrastructure in Bursa Nilüfer, this process, which requires a long preparation and patience, is successfully carried out through the coordinated work of specialist physicians, offering a lasting health investment that will improve individuals’ quality of life for a lifetime.
