Facial and Jaw Bone Injuries and Fracture Surgery
Facial and jaw bone injury surgery (Maxillofacial Trauma Surgery) focuses on diagnosing and treating fractures, dislocations, and soft tissue injuries affecting the face and jaw. This specialty ensures the restoration of facial appearance, oral function, and protection of vital structures such as the eyes, nose, and airways.
1- Common Causes of Facial and Jaw Injuries
- Road traffic accidents.
- Falls from height.
- Sports injuries.
- Industrial or workplace accidents.
- Physical assaults.
2- Types of Facial and Jaw Fractures
A. Jaw (Mandibular) Fractures
- Often occur in the lower jaw due to its exposed position.
- Can cause pain, swelling, difficulty opening the mouth, and misaligned teeth.
B. Maxillary (Upper Jaw) Fractures
- Affect the mid-face region.
- May be associated with nasal fractures and vision problems.
C. Zygomatic (Cheekbone) Fractures
- Can cause facial asymmetry, eye movement issues, or numbness in the cheek area.
D. Nasal Bone Fractures
- Most common facial fracture.
- Causes deformity, swelling, and difficulty breathing through the nose.
E. Orbital (Eye Socket) Fractures
- May lead to double vision, sunken eye appearance, and limited eye movement.
F. Combined/Complex Fractures
- Involve multiple facial bones, often due to high-impact trauma.
3- Symptoms of Facial Bone Injuries
- Swelling and bruising.
- Pain and tenderness at the injury site.
- Bleeding from the nose or mouth.
- Difficulty chewing, speaking, or opening the mouth.
- Numbness in the lips, cheeks, or chin.
- Changes in bite or facial alignment.
4- Diagnosis
- Clinical Examination: Assessment of facial symmetry, occlusion (bite), and sensory function.
Imaging Tests:
- X-rays (Panoramic view for jaws).
- CT scans for detailed bone evaluation.
5- Treatment Options
Treatment depends on the location, severity, and complexity of the fracture.
A. Non-Surgical (Conservative) Management.
- Suitable for minor, stable fractures without displacement.
- Includes soft diet, painkillers, and close monitoring.
B. Surgical Management
- Open Reduction and Internal Fixation (ORIF):
- Surgical exposure of fracture site.
- Fixation using titanium plates, screws, or wires to stabilize bones.
Reconstructive Surgery:
- For severe fractures or bone loss.
- May involve bone grafts or implants.
6- Post-Surgical Care
- Maintain oral hygiene to prevent infection.
- Follow a soft or liquid diet as advised.
- Avoid strenuous activity until fully healed.
- Attend regular follow-up appointments.
7- Possible Complications
- Infection.
- Malocclusion (misaligned bite).
- Nerve damage leading to numbness or tingling.
- Facial asymmetry.
- Vision problems (in orbital fractures).
