Can Lefort I Surgery Correct Maxillary Width Deficiency? - Dentistry

More Info

---

Lefort I surgery is a well-established surgical procedure primarily aimed at correcting maxillary (upper jaw) deformities, including width deficiencies. This procedure involves osteotomy (cutting of the bone) of the maxilla, allowing for repositioning of the upper jaw. In cases of maxillary width deficiency, Lefort I can indeed help increase the transverse dimension of the maxilla, which can improve facial aesthetics and function.

When the maxilla is narrow, it can lead to a concave facial profile, making the cheeks appear more prominent and the overall facial structure look less balanced. By performing a Lefort I osteotomy, the surgeon can reposition the maxilla laterally (outward), which can enhance the facial width and create a more harmonious appearance. This is particularly beneficial for patients who have a narrow maxilla that contributes to a sunken facial appearance.

In your case, since you are also considering a Bilateral Sagittal Split Osteotomy (BSSO) along with the Lefort 3-piece procedure, it is essential to understand how these surgeries work together. The BSSO is typically performed to correct mandibular (lower jaw) discrepancies, and when combined with Lefort I, it can provide comprehensive facial balance. The Lefort 3-piece technique allows for more complex movements of the maxilla, including lateral expansion, which can be particularly advantageous for addressing width deficiencies.

The Lefort 3-piece osteotomy involves separating the maxilla into three segments: the central segment (which includes the nasal area) and the two lateral segments (which include the zygomatic arches). This allows for greater flexibility in repositioning the maxilla, including widening it. The lateral segments can be moved outward, effectively increasing the width of the maxilla. This is particularly beneficial for patients who have a narrow maxillary arch and wish to achieve a broader facial appearance.

It is crucial to have a thorough discussion with your oral and maxillofacial surgeon regarding your specific goals and concerns. They will evaluate your facial structure, dental occlusion, and overall health to determine the best surgical approach for your needs. Additionally, they can provide you with information on the expected outcomes, potential risks, and recovery process associated with these procedures.

In summary, Lefort I surgery, particularly when performed as a 3-piece osteotomy, can effectively address maxillary width deficiencies. It can enhance facial aesthetics by increasing the transverse dimension of the maxilla, leading to a more balanced and harmonious facial profile. When combined with BSSO, these procedures can provide comprehensive correction of both upper and lower jaw discrepancies, ultimately improving function and aesthetics. Always ensure that you are well-informed and comfortable with your surgical plan by discussing all your questions and concerns with your surgical team.
