Orthognathic Surgery

What is Orthognathic Surgery?

Orthognathic surgery is a specialised branch of oral and maxillofacial surgery that focuses on correcting irregularities in the jaw and facial structure. It involves precise surgical techniques to reposition the upper and lower jaws, align the teeth, and improve the aesthetic and functional aspects of a person’s face.

Congenital Jaw Conditions Requiring Surgery

Orthognathic surgery is commonly recommended to address a variety of congenital jaw conditions, including:


A crossbite is a dental misalignment issue where a few upper teeth sit inside the lower teeth when the mouth is closed. It can affect one or more teeth and occur in the front or back of the mouth. Crossbites can lead to dental problems like premature wear and difficulty chewing.


An underbite is a jaw condition where the lower jaw stretches beyond the upper jaw when the mouth is closed. This misalignment can affect both the appearance and functionality of the teeth. It can result in difficulty in biting and chewing.


An overbite occurs when the upper front teeth extend beyond the lower front teeth when the mouth is closed. While a slight overbite is normal, excessive overbites can lead to issues like tooth wear and jaw discomfort.

Cleft Lip and Palate:

Cleft lip and palate are congenital conditions where a baby is born with a split or opening in the upper lip and/or the roof of the mouth (palate). These conditions affect a child’s ability to eat, speak, and even breathe.

Pierre Robin Sequence:

Pierre Robin Sequence is a congenital condition characterised by a smaller-than-normal lower jaw (micrognathia), a tongue that falls back in the throat (glossoptosis), and a cleft palate. This condition can result in breathing and feeding difficulties in newborns.

Jaw Problems Resulting from Injuries and Medical Conditions

Orthognathic surgery is also suitable for individuals who develop jaw problems due to injuries and medical conditions, including:

Facial Fractures:

These are the breaks or cracks in the bones of the face, often caused by trauma or accidents. These fractures can affect the jaw, cheekbones, nose, or eye sockets.


Jaw cysts are fluid-filled sacs that can develop within the jawbone. They may not always cause symptoms but can lead to discomfort, swelling, and even jawbone damage.


Jaw tumours can be benign or malignant growths in the jawbone. While benign tumours are non-cancerous, malignant ones can be cancerous.

Obstructive Sleep Apnea:

Obstructive Sleep Apnea (OSA) is a disorder characterised by repeated interruptions in breathing during sleep, often due to the relaxation of throat muscles. OSA can be associated with jaw problems, such as a small lower jaw.

Temporomandibular Joint Disorders (TMJ Disorders):

TMJ disorders are conditions that have an impact on the temporomandibular joint, a hinge that connects the jaw to the skull. These disorders can cause pain, discomfort, and difficulty in jaw movement. Treatment options include:

  • Lifestyle changes
  • Physical therapy
  • Oral appliances
  • Surgery

Ideal Candidates for Orthognathic Surgery

Ideal candidates for orthognathic surgery include individuals who:

  • Have jaw misalignments that affect their facial appearance or function.
  • Experience difficulty biting, chewing, or speaking due to jaw issues.
  • Suffer from sleep apnea or breathing problems related to jaw position.
  • Have facial asymmetry concerns due to jaw discrepancies.
  • Are committed to post-surgery orthodontic treatment to achieve the best results.

Steps Involved in Orthognathic Surgery

Orthognathic surgery is a comprehensive process that typically includes the following steps:

  1. Consultation: During this appointment, your oral health and jaw condition will be thoroughly assessed.
  2. Treatment Planning: Based on the assessment, a personalised treatment plan is developed. This plan outlines the specific procedures required to correct your jaw irregularities.
  3. Pre-Surgical Orthodontics: In many cases, pre-surgical orthodontic treatment is initiated to align the teeth and create an ideal bite.
  1. Surgery: All jaw-related surgeries are performed under general anaesthesia in a hospital setting. It involves repositioning the jawbones and securing them in the corrected position using specialised surgical techniques.
  2. Recovery: After the surgery, a period of recovery and healing is necessary. The patient may have to follow a liquid or soft diet during this period to promote proper healing and minimal discomfort.
  1. Post-Surgical Orthodontics: Following the healing period, you may continue orthodontic treatment to fine-tune the bite and tooth alignment.
  2. Follow-Up: Regular follow-up appointments are essential to monitor your progress and ensure the treatment is successful.

Orthognathic surgery is a life-changing procedure that not only improves the function of your jaw but also enhances your facial aesthetics. It is a comprehensive process that requires careful planning and expertise to achieve the best results.
