In 1932 Martin Wassmud introduced the concept of LeFort I osteotomy and since that time it has become the “workhorse” in conjunction with orthodontic treatment for the resolution of malocclusions, especially open bite. There are many technical nuances associated with the orthodontic preparation that will be discussed as well when the surgery is combined with coordinated orthodontic care, the long-term outcomes can be favorable. Appropriate diagnosis and patient selection are the keys to success as well as close interdisciplinary working relationships between surgeons and orthodontists.
