An osteotomy is a surgical operation whereby a bone is cut to shorten or lengthen it or to change its alignment. It is sometimes performed to correct a hallux valgus, or to straighten a bone that has healed crookedly following a fracture. It is also used to correct a coxa vara, genu valgum, and genu varum. The operation is done under a general anaesthetic.
Oral and maxillofacial surgery is a surgical specialty focusing on reconstructive surgery of the face, facial trauma surgery, the oral cavity, head and neck, mouth, and jaws, as well as facial cosmetic surgery/facial plastic surgery including cleft lip and cleft palate surgery.
Chin augmentation using surgical implants alter the underlying structure of the face, intended to balance the facial features. The specific medical terms mentoplasty and genioplasty are used to refer to the reduction and addition of material to a patient's chin. This can take the form of chin height reduction or chin rounding by osteotomy, or chin augmentation using implants. Altering the facial balance is commonly performed by modifying the chin using an implant inserted through the mouth. The intent is to provide a suitable projection of the chin as well as the correct height of the chin which is in balance with the other facial features.
Orthognathic surgery, also known as corrective jaw surgery or simply jaw surgery, is surgery designed to correct conditions of the jaw and lower face related to structure, growth, airway issues including sleep apnea, TMJ disorders, malocclusion problems primarily arising from skeletal disharmonies, and other orthodontic dental bite problems that cannot be treated easily with braces, as well as the broad range of facial imbalances, disharmonies, asymmetries, and malproportions where correction may be considered to improve facial aesthetics and self-esteem.
Distraction osteogenesis (DO), also called callus distraction, callotasis and osteodistraction, is a process used in orthopedic surgery, podiatric surgery, and oral and maxillofacial surgery to repair skeletal deformities and in reconstructive surgery. The procedure involves cutting and slowly separating bone, allowing the bone healing process to fill in the gap.
The Le Fortfractures are a pattern of midface fractures originally described by the French surgeon, René Le Fort, in the early 1900s. He described three distinct fracture patterns. Although not always applicable to modern-day facial fractures, the Le Fort type fracture classification is still utilized today by medical providers to aid in describing facial trauma for communication, documentation, and surgical planning. Several surgical techniques have been established for facial reconstruction following Le Fort fractures, including maxillomandibular fixation (MMF) and open reduction and internal fixation (ORIF). The main goal of any surgical intervention is to re-establish occlusion, or the alignment of upper and lower teeth, to ensure the patient is able to eat. Complications following Le Fort fractures rely on the anatomical structures affected by the inciding injury.
The surgical segment navigator (SSN) is a computer-based system for use in surgical navigation. It is integrated into a common platform, together with the surgical tool navigator (STN), the surgical microscope navigator (SMN) and the 6DOF manipulator (MKM), developed by Carl Zeiss.
Bone segment navigation is a surgical method used to find the anatomical position of displaced bone fragments in fractures, or to position surgically created fragments in craniofacial surgery. Such fragments are later fixed in position by osteosynthesis. It has been developed for use in craniofacial and oral and maxillofacial surgery.
Surgical planning is the preoperative method of pre-visualising a surgical intervention, in order to predefine the surgical steps and furthermore the bone segment navigation in the context of computer-assisted surgery. The surgical planning is most important in neurosurgery and oral and maxillofacial surgery. The transfer of the surgical planning to the patient is generally made using a medical navigation system.
Facial trauma, also called maxillofacial trauma, is any physical trauma to the face. Facial trauma can involve soft tissue injuries such as burns, lacerations and bruises, or fractures of the facial bones such as nasal fractures and fractures of the jaw, as well as trauma such as eye injuries. Symptoms are specific to the type of injury; for example, fractures may involve pain, swelling, loss of function, or changes in the shape of facial structures.
Zygoma reduction, also known as cheekbone reduction surgery, is a surgery used to reduce the facial width by excising part of the zygomatic bone and arch. Wide cheekbones are a characteristic facial trait of Asians, whose skull shapes tend to be more brachycephalic in comparison with Caucasian counterparts, whose skull shapes tend to be more dolichocephalic .This surgery is popular among Asians due to their inherent wide cheekbones. Due to the advanced surgical skills of Korean surgeons who perform facial contouring surgeries, the number of Asian people undergoing this surgery is increasing.
Piezoelectric bone surgery is a process that utilizes piezoelectric vibrations in the application of cutting bone tissue. The process was patented by Fernando Bianchetti, Domenico Vercellotti, and Tomaso Vercellotti. It was first used clinically in 1988. It is indicated for use in oral, maxillofacial, cranial and spinal procedures; but is mainly used in orthodontics and craniofacial surgery.
Colonel Robert G. Hale, DDS is an oral and maxillofacial surgeon and former Commander of the US Army Dental and Trauma Research Detachment. Hale lectures worldwide on craniomaxillofacial battle injuries and regenerative medicine. He is a researcher and public advocate for the advancement and benefits of regenerative medicine.
Surgically assisted rapid palatal expansion (SARPE), also known as surgically assisted rapid maxillary expansion(SARME), is a technique in the field of orthodontics which is used to expand the maxillary arch. This technique is a combination of both Oral and Maxillofacial Surgery and Orthodontics. This procedure is primarily done in adult patients whose maxillary sutures are fused and cannot be expanded via other techniques.
William Harrison Bell was an American Oral and Maxillofacial Surgeon and a Professor of Surgery who is known for his contributions to the field of Orthognathic Surgery. Dr. Bell's groundbreaking research provided a biologic basis for the Le Fort I osteotomy and other orthognathic surgical procedures used to reposition the facial skeleton. Active throughout his life, his later work provided a biologic rationale for distraction osteogenesis of the facial skeleton, a technique used to gradually lengthen bone at a rate of 1mm a day. A prolific author, his publications provided a thorough description of the diagnosis and management of dentofacial deformity, surgical technique, and detailed figures that illustrated the operations in sufficient detail that would provide generations of surgeons the necessary information from which to apply a surgical-orthodontic approach to facial deformity. He is credited in the United States with pioneering the transition of the field of Oral Surgery to become Oral and Maxillofacial Surgery.
Richard Trauner was an Austrian oral surgeon. Trauner is known for introducing the procedure of Sagittal Split Osteotomy to the United States in the 1960s with Hugo Obwegeser.
Hugo Obwegeser was an Austrian Oral and Maxillo-Facial Surgeon and Plastic Surgeon who is known as the father of the modern orthognathic surgery. In his publication of 1970, he was the first surgeon to describe the simultaneous procedure which involved surgeries of both Maxilla and Mandible involving Le Fort I and Bilateral Sagittal Split Osteotomy technique.
Shan K. Bagby is a United States Army brigadier general and the 28th Chief of the Army Dental Corps. Bagby also serves as the Commanding General, Regional Health Command-Central. Bagby, an oral and maxillofacial surgeon, was the Army’s first African-American dental officer promoted to brigadier general.
A Le Fort osteotomy is the name for three types of osteotomies of the jaw and face. They are based on the analogous bone fractures described by the French surgeon and physician René Le Fort.
Mandibular setback surgery is a surgical procedure performed along the occlusal plane to prevent bite opening on the anterior or posterior teeth and retract the lower jaw for both functional and aesthetic effects in patients with mandibular prognathism. It is an orthodontic surgery that is a form of reconstructive plastic surgery. There are three main types of procedures for mandibular setback surgery: Bilateral Sagittal Split Osteotomy (BSSO), Intraoral Vertical Ramus Osteotomy (IVRO) and Extraoral Ramus Osteotomy (EVRO), depending on the magnitude of mandibular setback for each patient. Postoperative care aims to minimise postoperative complications, complications includes bite changes, relapse and nerve injury.
