Le Fort I Osteotomy[edit | edit source]
.webp)
The Le Fort I osteotomy is a surgical procedure used to correct midface deformities and malocclusions by repositioning the maxilla. It is named after the French surgeon René Le Fort, who classified maxillary fractures into three distinct patterns. The Le Fort I osteotomy specifically addresses the horizontal fracture line that separates the maxilla from the pterygoid plates and nasal septum.
Indications[edit | edit source]
The Le Fort I osteotomy is indicated for a variety of conditions, including:
- Maxillary hypoplasia
- Vertical maxillary excess
- Open bite
- Crossbite
- Cleft palate
- Obstructive sleep apnea
This procedure is often part of orthognathic surgery to correct jaw alignment and improve facial aesthetics.
Surgical Technique[edit | edit source]
The procedure begins with an incision in the gingivobuccal sulcus, followed by careful dissection to expose the maxilla. The surgeon then performs a horizontal osteotomy above the roots of the teeth, extending from the nasal septum to the pterygoid plates. The maxilla is mobilized and repositioned according to the surgical plan, which may involve advancement, setback, or rotation.
Once the maxilla is in the desired position, it is stabilized using titanium plates and screws. The surgical site is then closed, and the patient is monitored for complications such as bleeding or infection.
Postoperative Care[edit | edit source]
Postoperative care involves:
- Monitoring for swelling and pain management
- Maintaining oral hygiene to prevent infection
- Dietary modifications, typically starting with a liquid diet
- Regular follow-up appointments to assess healing and stability
Patients may also require orthodontic treatment to fine-tune occlusion and ensure optimal results.
Complications[edit | edit source]
Potential complications of the Le Fort I osteotomy include:
- Infection
- Bleeding
- Nerve injury, leading to altered sensation
- Relapse of the maxillary position
- Sinusitis
