Le fort I maxillary advancement using distraction osteogenesis

Area of Science:

• Craniofacial surgery
• Orthognathic surgery
• Maxillofacial reconstruction

Background:

• Conventional Le Fort I osteotomies for maxillary hypoplasia carry significant relapse risks, particularly in cleft lip and palate patients due to anatomical and scarring factors.
• Severe maxillary hypoplasia requires advanced treatment options for stable and predictable outcomes.

Purpose of the Study:

• To review current data and recommendations for Le Fort I advancement using distraction osteogenesis.
• To present a technique for treating severe maxillary hypoplasia with internal distraction osteogenesis devices.

Main Methods:

• Review of existing literature on Le Fort I advancement with distraction osteogenesis.
• Description of a surgical technique utilizing internal distraction devices for severe maxillary hypoplasia.

Main Results:

• Le Fort I advancement with distraction osteogenesis is a viable and stable treatment for severe maxillary hypoplasia.
• This technique is effective in cleft, syndromic, and noncleft patients, offering improved stability over conventional methods.

Conclusions:

• Distraction osteogenesis provides a stable and predictable solution for severe maxillary hypoplasia, outperforming conventional techniques in high-risk populations.
• Internal distraction devices offer a refined approach for achieving stable maxillary advancement.
