New method of Le Fort I osteotomy with increased stability

Area of Science:

• Orthognathic Surgery
• Sleep Surgery
• Airway Management

Background:

• Maxillomandibular advancement (MMA) is crucial for widening the pharyngeal airway in sleep surgery.
• Postoperative maxillary backsliding is a significant complication following MMA.
• This relapse can negate the airway-widening benefits of the surgery.

Purpose of the Study:

• To introduce a novel surgical method to prevent maxillary retraction after orthognathic surgery.
• To address the issue of backsliding in maxillomandibular advancement procedures.
• To improve the stability of maxillary repositioning in sleep apnea surgery.

Main Methods:

• A modified surgical technique involving bone adjustment during maxillary advancement.
• Focus on stabilizing the anterior repositioning of the maxilla.
• Intraoperative bone manipulation to counteract posterior relapse.

Main Results:

• The devised surgical method effectively prevents maxillary backsliding.
• Stabilization of the maxilla in its advanced position is achieved.
• Improved long-term outcomes for patients undergoing MMA for sleep surgery.

Conclusions:

• The new surgical approach offers a solution to maxillary instability after orthognathic surgery.
• This technique enhances the predictability and efficacy of maxillomandibular advancement for airway improvement.
• Further studies should evaluate the long-term stability and patient-reported outcomes.
