Our Summary

This study looked at the use of a particular type of nerve block (a method of numbing a particular area) during double-jaw surgery. It used a drug called ropivacaine, and the researchers were trying to figure out the best amount to use. They split the patients into two groups - one group got a lower volume of the drug (2 mL) and the other got a higher volume (5 mL).

The researchers found that both amounts of the drug were equally effective at reducing pain after surgery. However, patients who received the lower volume were more likely to experience nausea in the first day after surgery. There were no other significant differences between the two groups in terms of side effects or complications.

Therefore, the study concluded that the lower volume of ropivacaine (2 mL) is just as effective as the higher volume (5 mL) at managing pain during double-jaw surgery. But, doctors might need to keep in mind that patients getting the lower volume might need extra help with managing post-surgery nausea.

Doctor’s Tip

A helpful tip a doctor might tell a patient about jaw surgery is to make sure to follow all post-operative instructions carefully, including taking any prescribed pain medications as directed, keeping the surgical area clean, and attending all follow-up appointments. It is also important to eat soft foods and avoid strenuous physical activity to allow for proper healing. Additionally, practicing good oral hygiene and gently massaging the jaw muscles can help with recovery. If any concerns or complications arise, it is important to contact your doctor immediately.

Suitable For

Patients who are recommended for jaw surgery typically have conditions such as:

  1. Severe malocclusion (misalignment of the teeth)
  2. Facial asymmetry
  3. Difficulty chewing or speaking due to jaw misalignment
  4. Sleep apnea
  5. Temporomandibular joint (TMJ) disorders
  6. Congenital jaw abnormalities
  7. Traumatic injuries to the jaw

These patients may benefit from jaw surgery to correct the underlying issues and improve their overall quality of life.

Timeline

Before jaw surgery:

  • Patient consults with oral and maxillofacial surgeon to discuss treatment options
  • Patient undergoes pre-surgical assessments, including x-rays, CT scans, and dental impressions
  • Patient may need to undergo orthodontic treatment to align teeth prior to surgery
  • Patient receives pre-surgical instructions, including fasting guidelines and medication adjustments
  • Patient undergoes jaw surgery, which can involve repositioning the upper jaw, lower jaw, or both
  • Patient is monitored in the recovery room before being transferred to a hospital room or discharged home

After jaw surgery:

  • Patient experiences pain, swelling, and bruising in the jaw area
  • Patient is prescribed pain medication and antibiotics to prevent infection
  • Patient may need to follow a liquid or soft food diet for a period of time
  • Patient attends follow-up appointments with the surgeon to monitor healing progress
  • Patient may undergo physical therapy to improve jaw function and reduce stiffness
  • Patient gradually resumes normal activities, including eating solid foods and returning to work or school
  • Patient may experience changes in facial appearance and speech as the jaw heals and settles into its new position
  • Patient may need long-term follow-up care to monitor for any complications or adjustments needed

What to Ask Your Doctor

Questions a patient should ask their doctor about jaw surgery include:

  1. Will I need a nerve block during the surgery?
  2. What type of nerve block will be used and how does it work?
  3. What are the potential side effects of the nerve block?
  4. Is there a choice between a lower or higher volume of the nerve block drug?
  5. What are the benefits and risks of using a lower volume vs a higher volume of the drug?
  6. How will the nerve block help manage pain during and after the surgery?
  7. How long will the effects of the nerve block last?
  8. How will post-surgery nausea be managed if I receive the lower volume of the drug?
  9. Are there any alternative pain management options available?
  10. What is the expected recovery time following jaw surgery?
