Orthognathic surgery is a means to address dental and facial deformities, for example, for mandibular protrusion and maxillary retraction, which is also known as geodesic deformity, it is usually necessary to perform a maxillary LeFort I osteotomy anteriorly and mandibular ascending sagittal splitting and retraction, which is a relatively large operation that requires the patient to be on a liquid diet for a longer period of time after the operation, and to clean the oral cavity only by rinsing the mouth, and it usually requires a bandage for 5 days, proposing a minimally invasive concept, whereby the patient can usually have the dressings removed by the second day after the operation, and the patient can brush his teeth and eat soft food, so that there is no major difference between the quality of life of the patient in his recovery from surgery and that of his pre-operative period.
