Post-Surgical Complications of Orthognathic Surgery - Neurology

Orthognathic surgery sequelae


I would like to inquire about the complications after orthognathic surgery.
I underwent orthognathic surgery two weeks ago, specifically a Lefort I 3-piece osteotomy for the maxilla and a BSSO SSRO for the mandible (not the commonly performed IVRO in large hospitals), without braces, only using bone screws and plates.

1.
Currently, I am experiencing a "tightness" around my upper and lower lips.
What could be the reason for this? Will it improve?
2.
Additionally, my right upper lip seems unable to exert downward force, causing my philtrum to tilt when I attempt to pucker my lips.
Is this due to damage to the motor nerve? My doctor mentioned it is because the muscles have not yet aligned, but I would like to know if there is a possibility of nerve damage and whether it will recover.

Dr. Gao Chunde reply Neurology


Issues in this area rarely come to the neurology department; at least, I haven't encountered them.
I believe the surgeon would be more concerned than you are.
The literature has reported similar cases, but they appear to involve only transient facial nerve dysfunction, with a generally good prognosis.
The surgeon is most familiar with your situation, and if there are any concerns, they should arrange for a consultation with another physician or relevant examinations.

Post-surgical complications following orthognathic surgery, such as the Lefort I and BSSO SSRO procedures, can vary widely among patients. Understanding these complications is crucial for effective recovery and management.
1. Tightness Around the Lips: The "tightness" you are experiencing around your upper and lower lips is a common postoperative symptom. This sensation is often due to swelling, inflammation, and the healing process of the tissues involved in the surgery. During orthognathic surgery, the repositioning of the jaw can affect the surrounding soft tissues, including muscles and nerves. As these tissues heal, they may feel tight or stiff. This sensation should gradually improve as the swelling subsides and the tissues adapt to their new positions. It is essential to follow your surgeon's postoperative care instructions, which may include gentle exercises to promote mobility and reduce tightness.
2. Difficulty with Lip Movement: The inability to exert downward force on your right upper lip, leading to asymmetry when performing actions like kissing, can be concerning. This issue may arise from several factors, including muscle healing, nerve function, or even the surgical technique used. Your surgeon's assessment that the muscles have not yet fully adhered or healed is a reasonable explanation. However, it is also important to consider the possibility of nerve involvement. The facial nerve, which controls the muscles of facial expression, can be affected during surgery, leading to temporary weakness or asymmetry.
In most cases, if there is nerve involvement, it is often temporary, and patients can expect gradual recovery over weeks to months. The timeline for recovery can vary significantly based on individual healing rates and the extent of the surgery. Regular follow-up appointments with your surgeon are crucial to monitor your progress and address any concerns.


Additional Considerations:
- Physical Therapy: If you continue to experience tightness or difficulty with lip movement, your surgeon may recommend physical therapy or specific exercises to help restore function and flexibility in the affected muscles.
- Nerve Recovery: If nerve damage is suspected, your surgeon may refer you to a specialist for further evaluation. Nerve recovery can take time, and while many patients see improvement, some may experience lingering effects.
- Communication with Your Surgeon: It is vital to maintain open communication with your surgical team. If you have concerns about your recovery, such as persistent tightness or asymmetry, do not hesitate to reach out. They can provide tailored advice and interventions based on your specific situation.

- Long-term Outlook: Most patients who undergo orthognathic surgery experience significant improvements in function and aesthetics over time. While some complications may arise, many are manageable and resolve with appropriate care.
In conclusion, the tightness around your lips and the difficulty with lip movement are not uncommon after orthognathic surgery. With time, proper care, and possibly some therapeutic interventions, you can expect improvement. Always consult your healthcare provider for personalized advice and to ensure that your recovery is on track.
