The three different types of orbital fractures include: Rim fractures that are commonly seen in car accidents; Blowout fractures when the rim remains intact but the floor of the eye socket is fractured; Direct orbital fractures, which are rim fractures extending to . They will take pictures of the eye and the eye socket, including x-rays and CT scans. The incidence of combined medial-inferior wall fractures was also significantly higher in the enophthalmos group (52.93%) than in the . The most common types of isolated orbital fractures found in our study were those of the orbital floor Orbital blow-out fractures can be divided into the following fractures:. A basic understanding of the various types of orbital fractures and their mechanism provides the framework with which to discuss trapdoor fractures. An orbital rim fracture may extend to the orbital floor to cause a direct orbital floor fracture. Note the relatively small amount of herniated tissue and the air-fluid level in the maxillary sinus. Blowout fractures: The orbital rim remains intact . To check for an orbital fracture, an ophthalmologist will examine the eye and the area around it. Forty-four patients with final diagnosis of orbital floor fractures in the period 1990-94 were retrospectively studied. Orbital floor fracture. There are three types of orbital fractures: Orbital rim fracture — Often caused by car accidents, orbital rim fractures affect the thick bone of the outer edges of the eye socket. Depending on whether the eyelid muscles are injured, an orbital fracture can cause double vision. on and type of orbital fracture based on observation of computed tomography scans. There are two types of orbital fractures: an orbital rim fracture and an indirect orbital floor fracture (blowout fracture). -inferior rectus. The most common fractures among the surgical patients were frontal bone (32.2%), ethmoid (25.2%), and zygomaticomaxillary complex/zygoma (12.2%). There are two primary types of orbital fractures: Indirect floor fractures: Also known as "blowout fractures," these are the most common type of orbital trauma. Anatomy Anatomically the orbit resembles a four sided pyramid. Orbital fractures are typically caused by a hard blow to the face. Here are a few types of bone fracture categories: Displaced Fracture: bone breaks into two or more pieces and moves out of alignment. Also called . Swollen forehead or cheek or swelling under the eyes. The ophthalmologist will check to see if the eye moves as it should, and if there are any vision problems. Forty-four patients with final diagnosis of orbital floor fractures in the period 1990-94 were retrospectively studied. Blood or discoloration in the white part of the eye. Because the rim is made up of very thick bone, an injury to this area has to carry a lot of force for a fracture to occur. [1] History and exam Key diagnostic factors diplopia on upward gaze derangement of globe position Of this group, over 80 percent will include ocular . In patients with facial fractures, 20 to 25 percent include orbital involvement at some level. Right orbital fractures were found in 11 cases (44%), while left and bilateral fracture locations were detected in 12 (48%) and 2 cases (8%), respectively. on and type of orbital fracture based on observation of computed tomography scans.

It can be caused by a motor vehicle accident, fall, sports injury, industrial accident or the like, and be serious enough to affect sight. The blowout fracture is the most common type of orbital fracture and is usually the result of trauma. The type of basilar fracture will help decide the patient's prognosis and treatment plan. This type of fracture is more likely in teen and young adult males who play certain sports. Many other injuries may accompany an orbital rim fracture, such as damage to the optic nerve. In addition to this, panorex or dental x-ray's are sometimes performed if a fracture to the jaw is suspected. A softball to the eye, a tumble to the floor, a gunshot wound while hunting, or a wayward fist at a local watering hole all might send a patient to the trauma center with an orbital or ocular injury. In most cases, these kinds of fractures are the result of trauma such as that caused by a fist or a hard ball. Sometimes parts within the eye socket, such as a muscle attached to the eye, are forced . They are orbital rim fractures, comminuted orbital wall fractures and trapdoor orbital wall fractures. Another mechanism of injury is a 'blow-in' fracture, where there is an inferiorly directed supraorbital force. This injury can also be called a "blowout" of the orbit. Difficulty in moving eyes left, right, up or down. If these bones are disrupted, as in the case of an orbital fracture, this can lead to severe eye damage. -Lockwood's ligament. Ophthalmologists most often get involved in pure orbital fractures with an intact orbital rim and without other facial bone fracture. Blindness or partial blindness, decreased field of vision, or blurriness are all common complications of an orbital blowout fracture. Orbital Fracture Diagnosis and Treatment. Facial numbness near the injury. An orbital fracture usually occurs after some type of injury or secondary to some blunt trauma to the face. Orbital fractures are caused by traumatic eye injury that fractures the bones of the orbit. Orbital roof fractures are more common in childhood as the frontal sinus has not yet pneumatised, therefore all posterior force to the superior orbital rim is transferred to the anterior cranial base. Get PDF. The bony fragments of the . There are many different types and patterns of fractures and each requires a different technique and procedure to repair it. Computed tomography … These bones are vital because they give the eye a strong structure. An orbital fracture, or a broken bone in the eye-socket, is a common type of traumatic facial injury. Share.

They occur when the thin floor of the eye socket cracks, leaving the rim unaffected . This type includes blow-out and blow-in patterns, as seen in isolated fractures of the orbital floor, medial wall, and roof. Direct orbital floor fractures. Hitting someone in the head with a baseball bat is an example of an incident that could result in a depressed . An injury resulting in an increase in intra-orbital pressure has 'blown out' the floor of the left orbit with the displacement of fragments into the maxillary sinus. This type of orbital fracture is called a "blow-out" fracture. Types of Orbital Fractures Orbital fractures can be classified into three distinct types: Blowout Fracture - The most commonly encountered, a blowout fracture occurs in the eye socket along the floor or inner wall near the nose and is often due to something hitting the eye with force, like a tennis ball or racquetball. The purpose of this research was to identify types of IOR fractures, related clinical findings and assess post treatment outcomes. Importance Orbital fractures are common in ocular trauma, and there is a need to develop predictive tools to estimate risk of concurrent ocular injury. They occur when the thin floor of the eye socket cracks, leaving the rim unaffected. There are many different types and patterns of fractures and each requires a different technique and procedure to repair it. What to know about orbital fractures.

Blowout fracture — A break of the thin inner wall or floor of the eye socket. They produced an impact on the orbital soft tissues of a cadaver, increasing . Department of oral and maxillofacial surgery Orbital fracture Done By AMRITHA JAMES 2. the ' hydraulic theory ' — the force of the impact is transmitted from the globe to the orbit, which fractures at its weakest point: the floor. Direct blows to the face can also transmit forces causing the same fracture. The 2 groups were compared by location and type of orbital fracture based on observation of computed tomography scans. Treating an orbital fracture varies by the severity and position of the injury along with any other head injury sustained at the time of the incident. An orbital fracture is a serious break or crack in one or more of the bones of the eye socket. Orbital Fractures . What causes a fracture of the orbit in a child? Non-Displaced Fracture: the bone breaks but does not move out of alignment. Objective To identify clinical and radiographic features that are associated with increased risk of substantial ocular injury in the setting of orbital fracture. The eye socket, or the orbit, surrounds the eye and protects it from external forces. Orbital rim fracture (in this type the outer bony edges are injured, the rim bone is a hard and thick bone, due to this only a blunt force trauma can cause injury to the rim bone. Orbital fractures (eye socket): There are three main types of orbital fractures. A common type of orbital rim fracture involves all three major parts of the eye socket. Orbital fractures can be localized or cover larger areas of the face. Plastic and Reconstructive Surgery.

The most common fracture by location was the orbital floor (20.6% and 30.1% on the right and left, respectively). An orbital fracture is when there is a break in one of the bones surrounding the eyeball (called the orbit, or eye socket). -intermuscular membrane. Symptoms of an orbital fracture may include: Blurry, decreased or double vision (diplopia). Orbital zygomatic fracture Medial orbital rim fracture Orbital floor fracture entrapment Orbital floor fracture Figures Orbital bones Orbital structures Eye muscles Positions of gaze Orbital fracture with proptosis and dystopia Sequential examination for facial trauma Pictures Enophthalmos trauma Proptosis and chemosis Getting hit with a baseball or fist often causes these breaks. In most cases, these kinds of fractures are the result of trauma such as that caused by a fist or a hard ball. Orbital floor fracture also known as "blowout fracture" of the orbit (eye socket). Severe cases often involve other conditions where the victim can suffer traumatic brain injuries (TBIs), head trauma, lacerations, disfigurement and other injuries as well. Orbital fractures are of three types, including orbital rim fractures, blowout fractures, and orbital . Car accidents are one of the main causes of this kind of fracture. In addition to this, panorex or dental x-ray's are sometimes performed if a fracture to the jaw is suspected. An orbital rim fracture requires a tremendous amount of force, so often the victim will have other serious injuries including an optic nerve avulsion or a traumatic brain injury. A traumatic malformation of the orbital floor or medial wall caused by the collision of a blunt item bigger than the orbital aperture, or eye socket, is known as an orbital blowout fracture. Of this group, over 80 percent will include ocular . A softball to the eye, a tumble to the floor, a gunshot wound while hunting, or a wayward fist at a local watering hole all might send a patient to the trauma center with an orbital or ocular injury. Orbital blowout fractures are particularly devastating types of injuries because they result in damage to the face and the boney structures, but also to the eye. A fracture is a broken bone in the eye socket involving the rim, the floor or both. A frontal bone or sinus fracture is when the upper part of the rim breaks. Orbital rim fracture — These are caused by a direct impact to the face, most commonly by an automobile dashboard or steering wheel during a car crash. Orbital Fracture Types. (1). Flatness of the cheeks. Fractures of the infra-orbital rim (IOR) are often undertreated with resultant compromise of facial esthetics and function. Non-Displaced Fracture: the bone breaks but does not move out of alignment. Types Facial fractures have been categorized according to multiple schemas, most famously according to a simplified three-tier Le Fort classification for complex midface fractures. Fractures involving more than one bone most commonly affect the orbital floor and zygomaticomaxillary complex 4. This is reflected in the demographics: it is more prevalent in young men. We found the incidence of medial wall fractures significantly higher in the enophthalmos group (76.06%) than in the nonenophthalmos group (22.92%, χ2 = 32.63, P < 0.05).

The incidence of combined medial-inferior wall fractures was also significantly higher in the enophthalmos group (52.93%) than in the . Interestingly, all left-sided fractures were more common than right-sided fractures when analyzed in aggregate (p<0.01), as depicted in Fig. Types of orbital facial fractures include: Orbital floor and/or nasal wall fracture ("blowout fracture"): occurs when the bony rim of the orbit remains intact, but the floor of the socket fractures. No abstract listed. Second one is frontal sinus fracture or frontal bone fracture which occurs in the upper edge of the eye rim and is also a part of the frontal bone of the forehead. In any case, many kinds of trauma can cause orbital fractures. The term 'blow-out fracture' was coined in 1957, when Smith and Regan 1 described the mechanism of injury. Conclusion. Purpose. Other structures within the face may require treatment as well such as the cheekbones or jaw. Orbital fractures are typically caused by a hard blow to the face. Tap card to see definition . Orbital fractures are classified in three categories. The floor and nasal sides of the eye socket are paper-thin, making fractures occur frequently in any kind of impact that involves the head or face. Abstract. Orbital fractures. One of the most serious types of eye injuries is called an orbital fracture. 3 Discussing. The floor of the orbit is formed from three bones: Maxillary bone Palatine bone Orbital plate of the zygomatic bone Orbital fracture 1. What to know about orbital fractures. An ophthalmologist treating a small orbital fracture may recommend ice packs placed over the injured area to allow the eye to heal on its own and reduce swelling. These happen when a rim fracture extends to the bottom of the eye socket and also creates. For many orbital fractures surgery is not necessary. -Tenon's Capsule. In the linear fracture type, a break occurs in the bones of the orbital floor that permits orbital tissue to prolapse into the fracture site during fracture formation. It is important to differentiate this type of fracture from other types of trauma . These can include being hit in the upper face with a baseball, tennis ball, steering wheel, or fist, or falling and striking the face on furniture, stairs, trampolines, or many other objects. Types of Treatment for Orbital Fractures According to the American Academy of Ophthalmology ( AAO ), surgical intervention is not always necessary in most eye socket fractures. Background: Selection of approach to treat orbital fractures involves multiple factors such as visibility and esthetics.Aims and Objectives: The aim of this study is to compare subciliary and infraorbital incisions for orbital floor and infraorbital rim fractures.Materials and Methods: We carried our study in twenty patients, who reported to the department of oral and maxillofacial surgery . There are two primary types of orbital fractures: Indirect floor fractures: Also known as "blowout fractures," these are the most common type of orbital trauma.
