Wound pain and swelling

Postoperative wounds may appearShort-term pain and swellingThis is the body.Part of the natural restoration process.

💡 Patients shouldTake painkillers on timeFollow your doctor's advice to apply ice and heat to relieve discomfort.

Bleeding and infection risk

In the early postoperative period, there may beSlight bleeding (dark red)However, if it turns bright red and bleeding continues, seek medical attention immediately.

💡 Patients shouldKeep the wound clean and use antibiotics as directed by your doctor, which can effectively reduce the incidence of infection.

Paralysis and paresthesia

During surgery, if nerves are involved, it may cause local paralysis or paresthesia.

💡 Usually temporary, but alsoIt may take longer to recover, you need to maintain close communication with your doctor.

difficulty swallowing

Some patients may experience difficulty swallowing and feel uncomfortable in the early postoperative period.Swallowing exercises are needed.

💡 Liquid food is the main food for the first week after surgery, avoid irritating or residue-containing foods, and avoid food residues in the mouth that may cause wound infection and inflammation.

Nasal airway obstruction

Postoperative swelling or blood clots may temporarily cause difficulty breathing. Once the swelling subsides, breathing will gradually become smoother and return to normal.

💡 In the early postoperative period, you need to practice and get used to mouth breathing.

How long does it take to recover from sleep apnea surgery (orthognathic surgery)?

Surgery for apnea

The recovery period after surgery varies depending on individual circumstances, the type of surgery, and the extent of the procedure. Generally speaking,The postoperative recovery period can be divided into the following stages.:

Initial recovery period (1-2 weeks):

  • Patients may experience pain, swelling, discomfort, or difficulty swallowing, and need ample rest and to follow their doctor's instructions regarding care and medication.
During the critical period of wound healing, avoid strenuous activity or forceful coughing and blowing your nose to prevent emphysema, bleeding, and other factors that could hinder wound healing.

Mid-term recovery period (after 2 weeks):

  • After the initial 1~2 weeks,Symptoms will gradually ease
  • Swallowing function and pronunciation will be improved
  • Patients can gradually resume their daily activities under the guidance of a physician
Avoid excessive exertion (such as clenching your teeth) or consumption of seafood, Chinese herbal supplements, or irritating foods such as alcohol or spicy foods.

Long-term recovery (more than 6 weeks):

  • 6 weeks after surgery,The swelling is also relatively obvious, and the effect is gradually stable after surgery.
  • Swallowing function and pronunciation will be improved
  • Patients can gradually resume their daily activities under the guidance of a physician
Patients need to adapt to the new breathing pattern and bite position. For surgeries involving skeletal or neurological adjustments, full recovery may take at least 3 to 6 months.

Patients should cooperate with regular follow-up visits and receive [treatment/care].Fenghua United ClinicThe doctor's follow-up examinations and postoperative recovery plan, such as tooth occlusion adjustment (wearing braces or orthodontic elastics, depending on the individual's situation), are necessary to ensure the effectiveness of the surgery.

FAQs about sleep apnea surgery (orthognathic surgery)

FAQs about sleep apnea surgery

Q: Can sleep apnea (orthognathic surgery) be cured through surgery?

Surgery can effectively improve symptoms of sleep apnea, especially for people whose sleep apnea is caused by structural problems such as a retracted jaw, small chin, or narrow airway.

However, the effectiveness of surgery varies from person to person and is related to the patient's cause of illness, the extent of surgery, and postoperative cooperation. Most patients will experience significantly improved sleep quality after the recovery period, but may also require changes in lifestyle habits or other auxiliary treatments to achieve the best results (needs to be evaluated by a physician).

Q: How many days does one need to be hospitalized for sleep apnea (orthognathic surgery)?

Orthognathic surgery usually requires one night of hospitalization

The doctor will assess whether to extend the hospital stay based on the stability after surgery.

Q: Will apnea recur after surgery (orthognathic surgery)?

Recurrence after surgery is possible, especially if people do not change their lifestyle habits (such as being overweight, smoking, or drinking too much).

Also, as people age, airway tissue may become loose again, causing symptoms to recur. To reduce the risk of recurrence, patients should follow their doctor's advice, maintain a healthy weight and lifestyle, and regularly track and evaluate their sleep status.

Comparison of airway cross-sections before and after orthognathic surgery in a 29-year-old male, showing postoperative airway dilation.

29-year-old man undergoes orthognathic surgery to completely cure apnea

A 29-year-old male patient was troubled by severe sleep apnea (AHI=39.6) and was unable to adapt to positive pressure respirator treatment. Through 3D customized orthognathic surgery, counterclockwise rotation technology is used to rotate the upper and lower jaw bones forward and perform bilateral turbinoplasty. The postoperative results were significant: AHI dropped to 4.7 (improved by 88.13%), minimum blood oxygenation increased from 79% to 94%, and respiratory tract volume increased by 76.6%. This case demonstrates the effectiveness of orthognathic surgery in the treatment of sleep apnea.

Treatment of sleep apnea in a 28-year-old man

A 28-year-old man sought treatment for severe sleep apnea. The preoperative AHI index was 45 and the lowest blood oxygen concentration was 76%. After diagnosis, it was found that the upper and lower jaw bones were underdeveloped, resulting in airway compression. Through 3D customized orthognathic surgery, counterclockwise rotation and forward movement of both jaws were performed. After the operation, the AHI index dropped significantly to 0.4, and the lowest blood oxygen concentration increased to 92%. The patient's symptoms such as snoring, light sleep and daytime sleepiness have been significantly improved, the respiratory space has been effectively improved, and the treatment effect is excellent.

Severe sleep apnea: Decided to undergo MMA orthognathic surgery for the sake of the child

A patient with severe sleep apnea (AHI=69.8) decided to seek treatment because of severe snoring that affected his family's quality of life, especially after the birth of his child, and daytime sleepiness. After trying non-surgical methods such as side sleeping, positive pressure respirators, and anti-snoring braces with limited results, I finally chose to undergo MMA orthognathic surgery. After the operation, the AHI dropped from 69.8 to 13, and the minimum blood oxygen concentration during sleep increased from 53% to 83%. This not only improved the mental and physical strength, but also made the family no longer need to wear earplugs to sleep.

In a case of orthognathic surgery for sleep apnea, the AHI (apnea-hypopnea index) decreased from 64.5 to 4.3 in the main visual field.

From AHI 64.5 to 4.3! Regaining a clear mind after surgery

This is a patient with extreme sleepiness. His Epworth Sleepiness Scale score is 17. If the score is over 10, it is considered to have reached the level of sleepiness that requires medical intervention. The sleep report he brought from the hospital showed that his AHI was as high as 64.5 (AHI>30 is severe sleep apnea) and his lowest blood oxygen level reached 60%. For patients with retruded mandible and severe sleep apnea, orthognathic surgery (Maxillo-Mandibular Advancement, MMA) should be one of the priority treatment options, especially since this patient is completely unable to accept having to wear a positive pressure ventilator for a long time. The CT scan after the operation showed that the narrow and blocked airway had been widened and supported through the reorganization of the upper and lower jaws. At the same time, the face shape, jaw line, tooth angle and bite state also benefited from the orthognathic surgery. Most importantly, the postoperative sleep report showed that the AHI had dropped to 4.3, which is the same as the normal standard, and the minimum blood oxygen level had increased to 83%. Subjectively, in addition to greatly reducing snoring, he felt much more energetic during the day and was not sleepy.

Headache and irritability turned out to be caused by severe obstructive sleep apnea

A young man was troubled by severe obstructive sleep apnea (OSA), with an AHI index as high as 55.8, and symptoms such as loud snoring, daytime sleepiness, headaches, and difficulty concentrating. Because he was unwilling to use a positive-pressure respirator, he underwent mandibular advancement surgery (MMA) combined with chin advancement surgery to successfully expand the airway space. The AHI dropped to 3.9 6 months after the operation, and his symptoms were significantly improved. This case demonstrates the therapeutic effect of MMA surgery on patients with severe OSA, providing patients with a treatment option that does not require respirators.
