Blowout fractures result from trauma to the orbital bones. When an object hits the orbital bones (usually the eye brow and upper cheek bone) the force is transmitted to the bones. If the force is great enough, the bones buckle and break. Any large object with force or speed can cause a blowout fracture. Typical causes include motor vehicle. Orbital fractures are a common presentation to ophthalmologists who treat blunt trauma, and fractures of the floor are the most common of all. The fragility of the orbital floor is eloquently considered in a chapter from Ophthalmic Care of the Combat Casualty, coauthored by Dr. Mazzoli. The orbital floor and medial wall, being adjacent to. The isolated orbital fl oor fracture often called as blow out fracture is a common presentation following blunt trauma. The most common orbital walls affected are fl oor and medial wall. The fl oor fractures may also occur in combination with zygomatic arch fractures, Le Fort II or III or with fracture of other orbital bones. However. Orbital blowout fractures are usually the result of a direct blow to the orbit, which causes a sudden increase in intraorbital pressure. Decompression then occurs by fracture of one or more of the bounding walls of the orbit. Although the causative trauma is usually substantial, presentation and diagnosis may be delayed in the setting of. Orbital Blow-Out Fractures. Any fracture of inferior or medial walls. Force is transmitted through globe and results in fracture of the fragile inferior or medial orbital walls. Pure Blow-Out Fracture. Isolated fracture of orbital walls. Occurs when small object strikes globe directly, without causing orbital ridge or rim fracture

An orbital blowout fracture is a fracture or break in the small bones that make up your eye. The orbit, or eye socket, is the cavity of the skull that holds the eye. An orbital blowout can occur when an object strikes the orbit with blunt force. This injury is commonly the result of a fist, baseball, or tennis ball that strikes the eye The term 'blow-out fracture' was coined in 1957, when Smith and Regan 1 described the mechanism of injury. They produced an impact on the orbital soft tissues of a cadaver, increasing.

  4. Blunt Orbital Trauma. The orbit is composed of 7 flat bones and is sometimes described as a pyramidal or conical-shaped chamber composed of a floor, roof, medial wall, and lateral wall ( Figure 2 ). The thinnest of these are the medial wall and inferior (floor) wall. Orbital Fractures. Fractures of the orbit are a common occurrence with facial.
  5. Workup in orbital floor fractures (blowout) Radiographs can be used for soft tissue but are limited by their lack of ability to detect differences in tissue density of less than 10%, making evaluation of soft tissue difficult at best. Anteroposterior views of the orbit usually are obtained with varying angulation of the x-ray beam vector
  6. A blow-out fracture occurs when the anterior orbit sustains an impact by an object of larger diameter than the orbit itself, e.g., a baseball or a fist. The blow causes increased intraorbital pressure fracturing its weakest part (the orbital floor or medial orbital wall) and not the globe itself ().However, given this mechanism of injury, there is a high incidence of ocular injury.
  7. Orbital floor fracture (Blowout fracture) Definition: Orbital contents are typically forced through a fractured orbital floor (blowout fracture). Mechanism of injury: high-velocity blunt trauma to the globe and upper eyelid (e.g., from a punch, tennis ball, etc.) that causes an indirect downward force to the infraorbital groove; Clinical feature

The most common presentation of orbital fractures is associated with zygomatic complex fractures (i.e., involving the cheek bone and thus the lateral orbital wall). The most common intraorbital fracture is the medial wall 'blow-out' fracture. al-Qurainy IA, Stassen LF, Dutton GN, et al. The characteristics of midfacial fractures and the. Figure 2a,2b. An example of a patient presenting with a right orbital floor blowout fracture. Bruising and limited eye movements secondary to swelling are common clinical presentations (top). CT scan demonstrates common findings of a blow out fracture with evidence of a depressed right orbital floor (bottom) A blowout Fracture of the orbital floor is defined as a fracture of the orbital floor in which the inferior orbital rim is intact. Etiology Fractures of the orbital floor are common: it is estimated that about 10% of all facial fractures are isolated orbital wall fractures (the majority of these being the orbital floor), and that 30-40% of all. Blowout fracture A blowout fracture is a break in the floor or inner wall of the orbit or eye socket. A crack in the very thin bone that makes up these walls can pinch muscles and other structures around the eye, keeping the eyeball from moving properly Medial orbital wall blow out fractures, by definition is a pure internal fracture confined to the orbital wall without involvement of orbital rim. Two theories have been proposed to explain how these fractures occur, the hydraulic or buckling mechanisms. Most likely it is a combination of these two mechanisms in the majority of cases

Parieto-orbital oblique (rhese), parietoacanthial waters, PA Caldwell (fueger), lateral (facial bones A blowout fracture is a fracture through any of the orbital walls, with an inferior fracture through the floor being the most common (Knipe). It is caused by direct force to the orbit. In children, nearly 50% of these injuries occur during sports, with the direct blow usually coming from a ball or another player (Hatton) Another common fracture is the orbital floor fracture, or blowout fracture. The usual mechanism is a blow to the eye, with the forces being transmitted by the soft tissues of the orbit downward to the thin floor of the orbit. The floor is usually the path of least resistance, and fractures downward into the maxillary sinus

An indirect orbital fracture or blowout fracture is a break in the floor of the eye socket. When these injuries occur the orbital rim stays intact, but a crack forms in the thin bone that makes up the base of the eye socket. This crack can pinch muscles and other anatomy around the eye, keeping the eyeball from moving properly.. Non-surgical management of blow-out fractures of the orbital floor Putterman et al.

Chung SY, Langer PD. Pediatric orbital. Fractures The most common orbital injury is a 'blowout' fracture, usually involving the orbital floor ± the medial wall. The malar complex is also commonly fractured in isolation by a blow to that area. The bones are either fractured or dislocated. The strong central part of the bone usually remains intact and the force is transmitted to the thre Orbital rim fracture - This is a fracture of the bones forming the outer rim of the bony orbit. It usually occurs at the sutures joining the three bones of the orbital rim - the maxilla, zygomatic and frontal. 'Blowout' fracture - This refers to partial herniation of the orbital contents through one of its walls. This usually occurs via blunt force trauma to the eye

Isolated orbital medial wall fracture was the most common type of blowout fracture in our series (n = 27; 61.4%), followed by combined floor and medial wall (n = 9; 20.5%) and isolated floor fracture (n = 8; 18.2%). Reasons for conservative treatment were as follows: patients declined surgery (n = 3; 6.8%), fracture was small (<50% of orbital.

Orbital fractures (eye socket): There are three main types of orbital fractures. Orbital rim fracture: The outer rim is the thickest part of the eye socket. It requires a lot of force to break the bone. Many other injuries may accompany an orbital rim fracture, such as damage to the optic nerve. Blowout fractures: The orbital rim remains intact. A blowout fracture is a fracture through any of the orbital walls, with an inferior fracture through the floor being the most common (Knipe). It is caused by direct force to the orbit. In children, nearly 50% of these injuries occur during sports, with the direct blow usually coming from a ball or another player (Hatton) Orbital floor fractures were first described by MacKenzie in Paris in 1884 [1]. Smith was the first to describe entrapment of inferior rectus between the fracture fragments. He was also the first to coin the term Blow out fracture [2]. Blow out fracture causes an increase in the intraorbital volume, this causes enopthalmos

Diplopia, nausea, vomiting with no subconjunctival haematoma in a young patient requires immediate referral 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 patients with facial fractures, 20 to 25 percent include orbital involvement at some level. Of this group, over 80 percent will include ocular.

Periorbital wall blowout fractures result from the backward displacement of the globe, caused by a blunt, non-penetrating object, which raises the intraorbital pressure sufficiently to fracture the orbital wall. Most commonly, it involves a posterior medial orbital floor, followed by the lamina papyracea of the ethmoid The term orbital blow-out fracture describes the injury that results from a blow to the orbit by an object that is too large to enter the orbit (fist, baseball, etc.). The force of the blow is absorbed by the orbital rim and is transmitted to the thinner orbital floor, which shatters, usually in the middle third near the infraorbital canal DISCUSSION . Orbital blowout fractures are caused by hydraulic mechanisms transmitting force through orbital soft tissue into the orbital walls, direct buckling mechanisms as the result of deformation of the bony orbital rim, or a combination of the two .In adults and children, the medial and inferior orbital walls are the most vulnerable to fracture due to their thin bone structure

Fractures of the orbital floor and the medial orbital wall (blowout fractures) are common midface injuries. Orbital fractures have a distinct trauma mechanism and are complex, due to the complex anatomy of the bony and soft tissue structures involved. Knowledge of anatomy is mandatory when dealing with patients presenting with trauma to the orbit Pediatric facial fractures comprise less than 15% of all facial fractures. Orbital blowout fractures constitute about 20% of all pediatric facial fractures. With increase in unsupervised physical activity and involvement in sports, a peak in fracture incidence occurs during puberty and adolescence . Diplopia in children is uncommon

The management of orbital blow-out fractures has always been a topic of controversy, and pediatric fractures are certainly not as well studied as adult fractures. The greater elasticity in pediatric bones as compared with adults results in greenstick deformity that manifests as trapdoor fractures. 1-7 Soft tissues such as extraocular muscle, intermuscular septa, and fat may become entrapped. One-third of children with orbital blowout fractures are admitted for head injury observations, while the true cause for the symptoms goes unrecognized and uninvestigated . Orbital blowout fractures in children require more swift intervention than in adults if muscle ischaemia and permanent impairment of the vision is to be avoided Orbital floor fracture. Orbital floor fracture also known as blowout fracture of the orbit (eye socket). Orbital floor fractures may result when a blunt object, which is of equal or greater diameter than the orbital aperture, strikes the eye or on the cheek 1)..

  1. A fracture through the orbital roof can result in a dural tear, with resultant CSF leakage or brain herniation . The trapdoor fracture is an inferior orbital blowout fracture in which the inferior rectus muscle herniates into the underlying maxillary sinus before the fractured fragment returns to its original position, entrapping the muscle.
  2. A blow-out fracture is a fracture of one of the walls or floor of orbit with an intact orbital rim. It is the commonest orbital fracture, with orbital floor fractures more common than medial wall fractures. It is produced by a blow to the orbit which suddenly increases the intraorbital pressure, fracturing a portion of the orbital bony lining
  3. The buckling theory of the formation of an orbital floor fracture: (a) The dorsal view of the inferior wall of the right orbit.The main mechanisms of blow-out fracturing of the orbital floor are wavelike deformations (shown with dashed lines) that are transmitted from the intraorbital rim to the orbital floor.(b, c) A horizontal impact (I 1) causes less significant deformation (D 1) compared.
  4. Orbital trauma may result in blowout fractures due to the increased pressure to the surrounding bone in the orbit. 1,2 This is most likely explained by the thin bone defining its anatomy and its closeness to the maxillary and ethmoid sinuses. 3 Another theory is that increased pressure applied to the infraorbital rim, directs the transmission of force directly to the orbital floor causing a.

10.1055/b-0039-173358 31 Orbital Floor Blowout Fracture RepairNicholas Mahoney Summary Orbital floor blowout fractures commonly occur as a result of blunt trauma to the orbit. Diplopia, enophthalmos, and infraorbital nerve hypoesthesia may result. Urgent surgical repair is indicated in the case of white-eyed blowout fractures with incarcerated muscle tissue within the fracture line Introduction. Orbital blowout fractures were first described in 1957 by Smith and Regan, who reported that they are caused by a sudden increase in intraorbital pressure.1 Blunt trauma to the orbit commonly causes fractures of the orbital floor and/or medial wall. In such cases, there may be trapping or prolapse of orbital soft tissue, and extraocular muscle dysfunction may cause diplopia and. PURPOSE: Blow-out fractures cause expansion of the bony orbital walls and prolapse of orbital contents in the sinuses. This can result in diplopia, enophthalmos, and hypoglobus. Early surgical repair has been previously recommended, however, recent reports show that delayed surgery can also be.

Recognition and Management of an Orbital Blowout Fracture

Orbital fracture is a common orbital injury that requires specific management as it can be a threat to vision, cause of diplopia and compromised cosmetic appearance. Orbital fractures are widely referred to as blow-out fractures [1-4]. However, they do not always involve only floor fractures an Conversely, studies of severe (postseptal) orbital infections rarely make reference to orbital fractures as being a significant pathogenetic factor. In a retrospective study of 130 orbital infections, three cases of severe orbital infection were identified as being associated with an orbital fracture, and are thus presented Editor-In-Chief: C. Michael Gibson, M.S., M.D. Overview. A blowout fracture is a fracture of the walls or floor of the orbit.Intraorbital material may be pushed out into one of the paranasal sinuses.This is most commonly caused by blunt trauma of the head, generally personal altercations 21.

High velocity compression of orbital contents can lead to orbital blowout fracture, and the paper-thin medial orbital wall (lamina papyracea) or the orbital floor are the commonest sites affected.1 Entrapment of the orbital soft tissues within the fragments of the fractured orbit can cause symptoms such as pain, enophthalmos, diplopia and disturbed eye movement.2 For the latter.

Orbital Floor Fractures (Blowout Fractures) Clinical

Etiology. Orbital fractures occur when the force generated by blunt trauma exceeds the tolerances of the bony surfaces. Medial wall fractures can result from either directly as injuries to the face or indirectly as blowout fractures, [2] theorized to occur from a direct buckling of orbital bones or a hydraulic mechanism involving indirect transmission of forces An 8-year-old girl presented to our emergency department with a headache, nausea, and double vision. 2·5 h earlier, she had been hit on her right eye by a football during a physical education lesson at school. According to her parents, she had vomited and appeared to be lethargic. On physical examination, her heart rate was 64 beats per min, and she had a haematoma around the right zygoma.

Since the term blow-out fracture was popularized in the seminal work by Smith and Regan 1 in 1957, there has been an ongoing discussion on when and how to treat it. Early intervention was the standard at the time, 2 but Putterman et al 3 put an opposing approach forth 2 decades later, stating that observation and later intervention were preferable. They noted that surgery was not without its. Purpose. To determine factors associated with the presence of significant ocular injury in subjects with orbital fractures. Subjects. A consecutive prospective cohort of 161 patients presenting to a general tertiary referral hospital with orbital fractures and undergoing initial conservative treatment was identified. Subjects were assessed at time of injury for the need for emergency surgery. This difference in the age of presentation between the sexes was statistically significant (P < 0.001). 103 subjects had blowout fractures and 24 had fractures of facial bones distant to the orbit. 16 patients had orbital fractures involving both orbits
