Le Fort fractures are typically the result of forceful impact to the face. They are often caused by rapid deceleration car crashes in which the midface strikes a stationary object, such as the car's dashboard. It can also occur if the midface is struck by a rigid object, such as a baseball bat . Le Fort injuries are complex fractures of the midface, named after Rene Le Fort who studied cadaver skulls that were subjected to blunt force trauma. His experiments determined the areas of structural weakness of the maxilla designated as lines of weakness where fractures occurred
Le Fort I (red), II (blue), and III (green) fractures A Le Fort fracture of the skull is a classic transfacial fracture of the midface, involving the maxillary bone and surrounding structures in either a horizontal, pyramidal or transverse direction Le Fort Type I: Floating palate Involves a transverse fracture through the maxilla. Occurs above the roots of the teeth and may result in mobility of the maxilla and hard palate from the midface Can be associated with malocclusion and dental fractures
The term LeFort fractures is applied to transverse fractures of the midface. Rene' LeFort described three transverse weak lines through the midfacial skeleton as a result of his cadaver studies in 1901. Images by RosarioVanTulpe - Own work Le Fort I fracture The fracture line commences at the point on the lateral margin of the anterior nasal aperture, passes above the nasal floor, and it passes laterally above the canine fossa and traverses the lateral antral wall, dipping down below the zygomatic buttress and then inclines upward and posteriorly across the pterygomaxillary fissure to fracture the pterygoid laminae at the junction of their lower thrid and upper 2 /3rds 1901 - René Le Fort described fracture classifications based on experiments conducted in 1900 by dropping bricks on 35 cadavers and observing the pattern of maxillary fractures. Le Fort used intact cadaver heads, and delivered blunt forces of varying degrees of magnitude and direction Le fort I/ Floating fracture/ Guerin fracture/ Low levelfracture/ Subzygomatic fracture1. Mobility of maxillary alveolar segment (floating fracture)2. Pain and tenderness while speaking or clenching3. Ecchymosis or laceration in labial or buccal vestibule4
Le Fort fractures are often caused by oblique, high-energy force vectors, lending to asymmetric involvement of each hemifacial unit. When two patterns or different categories of Le Fort fractures are involved in a single patient, the higher Le Fort classification is often applied when naming the fracture (Fig. 1.13.18) This EMTprep Education Segment reviews Le Fort Fractures and how they're classified. Knowing this information can help you on test questions and in the field..
Type 1. Transverse fracture through the maxillary sinuses, lower nasal septum, pterygoid plates. Direct horizontal impact to the upper jaw. Type 2. Oblique fracture crossing zygomaticomaxillary suture, inferior orbital rim, nasal bridge. Direct impact to the central midface. Type 3. Fracture above the zygomatic arch, through the lateral and. LeFort fracture Orthopedics A bilateral fracture of the maxilla, which is divided into 3 types, defined by R LeFort in 1901 LeFort fractures I Dentoalveolar dysjunction Fracture lines are transverse through the pyriform aperature above the alveolar ridge and pass posteriorly to the pterygoid region; the diagnosis is suggested by lip lacerations.
Le Fort I fractures primarily involve the maxilla. Le Fort II fractures primarily involve the maxilla, nasal bridge, lacrimal bones, orbital floors, and orbital rims. Le Fort III fractures involve the nasal bridge, medial orbital walls, lateral orbital walls, maxilla, and zygomatic arch Get free dental books, notes, and more dental videos by participating in a short survey.

Le Fort II fracture is pyramidal in shape with teeth at base of pyramid and nasofrontal suture at apex of pyramid. Pterygoid plates are broken, as is true in all types of Le Fort fracture. Posterior and lateral walls of maxillary sinus are broken as fracture skirts inferior in relation to body of zygoma Le Fort I fractures (horizontal) may result from a force of injury directed low on the maxillary alveolar rim in a downward direction. The fracture extends from the nasal septum to the lateral pyriform rims, travels horizontally above the teeth apices, crosses below the zygomaticomaxillary junction, and traverses the pterygomaxillary junction to interrupt the pterygoid plates
Signs and symptoms of Le Fort III fracture are tenderness and separation at frontozygomatic suture, lengthening of face, and hooding of eyes. Related: Types of Hip Fractures Surgical Procedure for Le Fort Osteotomies The Le Fort osteotomies are carried out under general anesthesia after the patient have been stabilized A principle in all Le Fort fractures is to reestablish the premorbid dental occlusion. Portions of the pterygoid plates and associated musculature are still attached to the posterior portion of the maxilla, so passive mobilization of the fracture can be difficult Midface fracture involving the maxilla and surrounding facial structures Most commonly occur due to motor vehicle accident LeFort I fractures are isolated to the lower face Type II and III injuries associated with cribriform plate disruption and CSF rhinorrhe Le Fort found three basic patterns of maxillary fracture lines: transverse, pyramidal and craniofacial disjunction (Fig. 1). The transverse fracture is the Le Fort I fracture through the maxilla, cephalic to the maxillary dentition. Open in a separate window Fig. Le Fort III fractures: (transverse) Also called craniofacial separation, the result of impact to the nasal bridge or upper maxilla. In some instances, maxillary fractures are a combination of two or three Le Fort types. Although this system of classification is considered somewhat simplistic today, it is still widely used in medicine
Le Fort fracture pearls are as follows: (a) All Le Fort fractures require disruption of the pterygoids from the posterior maxilla, as seen at axial imaging. (b) Any combination of Le Fort I, II, and III patterns can occur. (c) A sagittal or parasagittal hard palate fracture with a Le Fort pattern will result in a widened maxillary arch Le Fort III (craniofacial dysjunction) - mobility of the complete mid-face, with movement detected at the frontonasal and frontozygomatic sutures. Midline palatal fractures may result in independent movement of the right and left maxillae, and are frequently associated with laceration of the palatal mucosa A LeFort fracture is a fracture of the midface bone, cheek bones, and the bones under the eye. These fractures may occur alone or in combination with fractures of the jaw. Injuries to the eyes or brain are common A Le Fort fracture is a fracture of the midface that result in the separation of all or a portion of the midface from the skull base. It is the panfacial fracture that occurs in the midfacial region and involves the maxillary bone and surrounding structures in the horizontal, pyramidal or transverse direction .5% (n=35, 18 cases with Le Fort I+II fracture, 10 cases with Le Fort II+III fracture and 7 cases with Le Fort I+ II+III fracture)
Le Fort fractures rarely occur in isolation; always evaluate for other injuries. Le Fort-type fractures should be suspected if a pterygoid fracture is noted on a facial CT scan. These 3 fracture types may occur in combination either on the ipsilateral or contralateral side. The management goals are the restoration of form and function Le Fort injuries are complex fractures of the midface, named after Rene Le Fort who studied cadaver skulls that were subjected to blunt force trauma. Hi Le Fort Fractures. René Le Fort studied the various types of fractures involving the facial bones and created a classification system for certain types of these fractures - they are now referred to as Le Fort fractures. Le Fort fractures involve separation of all or a portion of the midface from the skull base. Force on the face result in.
Le Fort III: involves the zygomatic arch. Figure 6. Coronal non-enhanced CT image of the paranasal sinuses. The blue arrows show bilateral fracture of the pterygoid processes, which is a common association in all three types of Le Fort fractures. Figure 7. Axial non-enhanced CT image of the paranasal sinuses Le Fort fracture bilateral horizontal fracture of the maxilla. Le Fort fractures are classified as follows: Le Fort I fracture, a horizontal segmented fracture of the alveolar process of the maxilla, in which the teeth are usually contained in the detached portion of the bone.Le Fort II fracture, unilateral or bilateral fracture of the maxilla, in which the body of the maxilla is separated. Rene Le Fort utilized cadaver studies in 1900 to offer comprehensive explanations of 3 fundamental kinds of facial fracture, they're now termed as Le Fort I, Le Fort II & Le Fort III Fractures. LeFort Facial Fracture Types. Le Fort made his categories depending on work with cadaver skulls, and the categorization system has been criticized as. Le Fort fractures constitute a subset of injuries that result in discontinuity of the midface, a structure comprised of the maxilla, inferiolateral orbital rims, sphenoids, ethmoids, and zygomas. Feb 18, 2014 - Facial Fractures The bones of the skull and face collectively make up the most complex area of skeletal real estate in the body. Analysis of the fractured face requires a knowledge of not only normal anatomy, but also of common fracture patterns in the face. Le Fort fractures. Visit the post for more. Jhamika Kemp. 5.
These fractures are classified into three distinct groups based on the direction of the fracture: horizontal, pyramidal or transverse. The pterygoid plate is involved in all types of Le Fort fractures. This may result in a pterygomaxillary separation. The absence of a pterygoid fracture rules out a Le Fort fracture Le Fort III - the facial bones are completely separated (craniofacial dysjunction) from the skull with fractures through the medial and lateral walls of the orbits and through the zygomatic arches Multiple fractures can be present and the different fracture types may co-exist. Le Fort I, II, and III fractures are illustrated by Image C
Le Fort Osteotomy refers to the group of osteotomies carried out to treat various degrees of maxillary fractures and deformities. Maxillary fractures account for approximately 6-25% of all facial fractures. Much of the understanding of patterns of fracture propagation in midface trauma originates from the work of René Le Fort sence of a Le Fort fracture. In addition, each of the Le Fort fractures has a unique compo-nent. The purpose of this pictorial essay is to illustrate the use of these unique components to easily and quickly identify which type of Le Fort fracture is present. Unique Component of Each Type of Le Fort Fracture Figures 1, 2, and 3 illustrate the.
The Le Fort III fracture is a transverse fracture from the nasal bridge across the orbit and zygomatic arch/frontozygomatic suture to the pterygoid plates and the base of the sphenoid, leading to a free-floating face and thus also termed craniofacial disjunction.

Deze fracturen beginnen bij de nasofrontale en frontomaxillaire hechtingen en strekken zich posterieur. Fractura de Le Fort I (horizontal), también conocido como paladar flotante, puede ser el resultado de una fuerza de lesión dirigida hacia abajo en el borde maxilar alveolar, o fila dental superior, en una dirección descendente.El componente clave de estas fracturas, además del implicación de la placa pterigoidea, es la afectación del margen óseo lateral de la abertura nasal This chapter discusses the Le Fort reduction technique. Preoperative antibiotics are given to cover sinus flora and wound contamination. The patient is prepped and draped to include both the oral cavity and the maxillofacial skeleton. Fractures are typically reduced and fixated with a bottom‐ to‐top rationale Le Fort Fractures of the Face Fractures of face bones described by Rene Le Fort (1869-1951). There are three types of Le Fort fractures. The type I Le Fort fracture is a horizontal fracture of the alveolar process of the maxilla, with the teeth contained in the detached fragment (see figure below)
