Le Fort I Osteotomy: Advancing Upper Jaw for Facial Harmony
A le fort i osteotomy is a precise surgical procedure designed to reposition the upper jaw (maxilla). This advanced upper jaw surgery corrects dental and skeletal discrepancies, significantly improving oral function and facial aesthetics. It addresses conditions such as midface deficiency, gummy smile, and open bite by allowing three-dimensional movement of the maxilla. As a cornerstone of orthognathic surgery, a le fort i osteotomy achieves proper bite alignment and enhances overall facial harmony. Understanding this procedure reveals its critical role in comprehensive jaw correction.

What is a Le Fort I Osteotomy and How Does it Reposition the Upper Jaw?
A le fort i osteotomy is a surgical procedure that precisely cuts and repositions the maxilla (upper jaw). It corrects dental and skeletal discrepancies, improving oral function and facial aesthetics. The surgeon can move the maxilla forward, backward, upward, or downward to achieve proper alignment and balance.
This procedure is a cornerstone of corrective jaw surgery, allowing three-dimensional correction of the upper jaw’s position. Altering the maxilla’s placement can resolve complex bite issues, improve breathing, and create a more harmonious facial profile. Its versatility addresses functional and cosmetic concerns of the midface.
Understanding Maxillary Osteotomy for Facial Harmony
Maxillary osteotomy is any surgical cut of the maxilla bone. The Le Fort I is the most common type, targeting the jaw portion that holds the upper teeth. It is a fundamental component of orthognathic surgery, a field correcting jaw and face conditions. The goal is to achieve proper bite alignment (occlusion) and facial harmony, ensuring the upper jaw relates correctly to the lower jaw and other facial structures.
Why Might You Need Upper Jaw Surgery? Indications for Le Fort I
Upper jaw surgery may be recommended for functional and aesthetic concerns that orthodontics alone cannot resolve. Indications often involve a size or position mismatch of the upper jaw relative to the lower jaw or skull base.
Common indications include:
- Midface Deficiency: When the upper jaw is underdeveloped or set back, it can create a sunken mid-face and an underbite (Class III malocclusion). Maxillary advancement moves the jaw forward, correcting the bite and improving the facial profile.
- Vertical Maxillary Excess: This condition often causes a “gummy smile,” where excessive gum tissue is visible when smiling, and may prevent comfortable lip closure.
- Open Bite: An anterior open bite occurs when the front upper and lower teeth do not touch when the mouth is closed, causing chewing and speech difficulties. Maxillary repositioning is a common method for open bite surgery.
- Facial Asymmetry: A canted or uneven upper jaw can cause significant facial asymmetry. The procedure levels and centres the maxilla to restore balance.
Correcting a ‘Gummy Smile’ and Open Bite with Maxillary Impaction
For a gummy smile, the surgeon performs a maxillary impaction, removing a bone wedge to move the upper jaw upward. This reduces the maxilla’s vertical height, decreasing gum exposure and allowing natural lip closure. To correct an open bite, the jaw may be moved downward or repositioned so the front teeth meet properly. These movements are planned before surgery for a predictable, stable result, as detailed in understanding mandibular and maxillary osteotomies.
The Le Fort I Surgical Procedure: A Detailed Overview
The Le Fort I procedure is performed under general anaesthesia. A key patient benefit is the use of intraoral incisions—cuts made inside the mouth above the upper teeth—which avoids visible external facial scarring.
The surgical cut is made above the tooth roots and passes through the maxillary sinus, an air-filled space within the cheekbones. Surgeons take sinus precautions to protect the sinus lining and ensure proper healing. This is a standard, safe aspect of the surgery when performed by an experienced specialist.
Key Steps in Maxillary Advancement and Repositioning
The surgical sequence is based on pre-operative planning, often including 3D imaging and virtual surgical planning for accuracy. While each operation is tailored to the patient, the steps are consistent. For details on integration with lower jaw procedures, see combined jaw surgery.
View data as table
| Stage | Description | Surgical Goal |
|---|---|---|
| 1. Incision and Exposure | An incision is made in the gum line above the upper teeth, from molar to molar. Soft tissue is lifted to expose the maxillary bone. | Access the upper jaw bone without external cuts. |
| 2. Osteotomy (Bone Cut) | A precise horizontal cut is made through the maxilla, separating the tooth-bearing jaw portion from the facial skeleton. | Mobilise the upper jaw for free movement. |
| 3. Repositioning | The mobilised upper jaw is moved to its pre-planned position. A surgical splint may guide the jaw into the correct bite. | Achieve desired functional and aesthetic alignment. |
| 4. Fixation | The jaw is secured in its final position with small titanium plates and screws. These are biocompatible and usually remain permanently. | Provide rigid stability for bone healing in the new position. |
| 5. Closure | The gum tissue is repositioned, and the incision is closed with dissolvable sutures. | Complete the procedure and begin healing. |
Navigating Recovery and Expected Outcomes After Upper Jaw Surgery
Recovery from upper jaw surgery is gradual and requires following post-operative instructions. The initial phase focuses on managing swelling, discomfort, and diet. Swelling peaks in the first 72 hours and subsides over 2-3 weeks, though residual puffiness can last for months.
Patients follow a liquid or soft, non-chew diet for several weeks to allow undisturbed jaw healing. The titanium plates and screws used for fixation are generally not felt after healing and integrate with the bone. Most patients return to work or school in 2-4 weeks and strenuous exercise after 8-12 weeks, depending on their activities.

| Phase | Typical Duration | Key Activities & Restrictions |
|---|---|---|
| Initial Hospital Stay | 1 – 2 nights | Pain and swelling management; liquid diet initiated. |
| First Week Home | 1 week | Significant swelling; strict liquid diet; focus on rest. |
| Early Healing | 2 – 6 weeks | Swelling subsides; transition to soft, non-chew diet; light activity only. |
| Bone Healing | 6 – 12 weeks | Return to normal diet gradually; clearance for most physical activities. |
| Final Maturation | 6 – 12 months | Final aesthetic results appear as residual swelling resolves. |
Understanding Facial Changes: Will My Nose Change After a Le Fort I?
Patients often ask if the surgery will alter their nose’s appearance. Because the upper jaw forms the nasal cavity floor, moving it can affect overlying soft tissues. Advancing or impacting the maxilla can cause the nose base to widen slightly and the tip to rotate upward. Surgeons anticipate these changes and may use techniques like an alar base cinch suture to control nostril width and maintain nasal aesthetics. This detail is crucial for balanced facial changes. This structural relationship is documented in resources like the Wikipedia page on the Maxilla.

Frequently Asked Questions
How does a Le Fort I procedure correct a “gummy smile”?
To correct a gummy smile, clinically known as excessive gingival display, the surgeon performs a maxillary impaction. A small segment of bone is removed from above the teeth, allowing the entire upper jaw to be moved upwards, often by 2-4 millimetres. This movement reduces the amount of gum tissue visible when smiling and is planned with 3D imaging for a natural result.
Will upper jaw surgery change the appearance of my nose?
Yes, repositioning the maxilla can subtly alter the base of the nose, sometimes causing the nostrils to widen or the tip to upturn slightly. An experienced surgeon anticipates these changes and can use specific techniques, such as an alar base cinch suture, during the procedure to control the final nasal shape and maintain facial harmony.
Why is blowing your nose forbidden after a Le Fort I osteotomy?
The surgical cut for a le fort i osteotomy is made just above the roots of the upper teeth, directly below the maxillary sinus floor. Blowing your nose forcefully can create pressure that drives air or sinus fluids through the healing bone into surrounding soft tissues, a complication known as surgical emphysema. This restriction is typically advised for at least 2-3 weeks post-surgery.
Are the titanium plates and screws used in jaw surgery removed later?
The small titanium plates and screws used to fix the jaw in its new position are biocompatible and designed to remain in place permanently. They integrate with the bone and do not typically cause any issues or set off airport metal detectors. Removal is uncommon and only considered if a plate becomes exposed or causes irritation, which occurs in a very small percentage of cases.
How long until I can eat solid food after maxillary surgery?
A return to a normal diet is gradual and follows key bone healing milestones. Patients typically adhere to a liquid-only diet for the first 1-2 weeks, progressing to a soft, non-chew diet for the following 4-6 weeks. Most patients are cleared to begin reintroducing harder foods around 8-12 weeks after their procedure, once sufficient healing is confirmed by the surgical team.
Will I have visible facial scars from this type of jaw surgery?
No, all incisions for this procedure are made entirely inside the mouth. The surgeon makes a cut in the gum line high above the upper teeth, in an area called the buccal sulcus. This intraoral approach means there are no external cuts and therefore no visible scars on the face.
