One of the things we see with orbital floor fractures, what we call a blowout fracture, is that the eyeball itself is often the conduit of force, said Jon M. Braverman, MD, associate clinical professor of ophthalmology at the University of Colorado in Denver. They are located approximately 5 to 7 mm lateral to the medial canthal angle (circled in, Canaliculi: The canaliculi connect the puncti to the lacrimal sac. A growing body of literature suggests observation in certain circumstances, but these decisions are best determined on a case-by-case basis by the evaluating oculoplastic surgeon. After detailed ophthalmologic examinations, there was no sign of intraorbital 1999 Jun;103(7):1839-49. The area damaged most easily by trauma is the particularly thin lamina papyracea, which separates the orbit from the ethmoidal sinuses. Aesthet Surg J. It articulates above with the orbital plate of the frontal bone, How would you describe an honorable person? Medial rectus muscle: The medial rectus muscle originates at the annular tendon, a fibrous ring surrounding the optic canal at the orbital apex. The traditional mechanism that we all learn in residency is that an object big enough to stop at the orbital opening yet small enough to protrude into and compress the orbital contents, such as a tennis ball, baseball or fist, abruptly increases the pressure within the orbit. Otolaryngol Head Neck Surg 2003; 129:43. Similar fractures in children may take only 4 or 5 weeks to heal. Lamina papyracea is Latin for paper-thin, which is an appropriate term to describe this thin sheet or paper-like osseous structure. Medwave. These days, we tend to use titanium microplates on the rim and porous polyethelene for the floor, even if we have to anchor the polyethelene to the titanium in order to cantilever a plate out over large fractures.

The lamina papyracea, translated from Latin as thin wall, is part of the ethmoid bone and is the thinnest bone of the orbit. It could be that levels of the anti-inflammatory hormone cortisol are naturally lower at night; plus, staying still in one position might cause joints to stiffen up. However, the type of symptoms you experience may be an indicator of which sinus cavity is causing you discomfort.

In: StatPearls [Internet]. How many deaths are caused by flu each year? In small fractures a hinged plate often drops down, allowing the soft tissues to herniate; then the plate hinges back up and incarcerates those tissues, which tethers the eye. Two-dimensional axial and coronal views can accurately image the disruption of the medial orbital wall and demonstrate herniation of periorbital soft tissues into the ethmoid sinuses (, Three-dimensional (3D) reconstructions of orbital CT scans are generally not helpful in diagnosing medial orbital wall fractures.

Zygomaticomaxillary complex, frontal sinus, and orbital fractures can lead to orbital infection and preexisting sinus disease appears to contribute to the risk of infection. American Cancer Society. Symptoms of medial orbital wall fractures include pain with extraocular muscle movement, ecchymoses, and periorbital edema. It inserts onto the medial surface of the globe and is innervated by the inferior division of the oculomotor nerve. By removing a small part of the bone that is part of your orbital bones, your surgeon will be able to remove the tumor. Proc Am Thorac Soc. To simulate the three components of the normal medial canthal tendon (anterior horizontal, posterior horizontal and vertical,the disrupted medial canthal tendon or medial canthal tendon with attached bone fragment is secured to a point corresponding to the top of the posterior lacrimal crest (40). Orbital cellulitis: a rare complication after orbital blowout fracture. Ethmoid cancer is very rare and is typically categorized as a paranasal malignancy. If you have a mild fracture, you wont need surgery. Lacrimal caruncle and plica semilunaris (semilunar fold): The lacrimal caruncle sits at the medial corner of the eye between the upper and lower eyelids, in close proximity to the medial canthal tendon. The orbital plate of the ethmoid bone accounts for the largest portion of the medial orbit wall. An extensive labyrinthine network of honeycomblike pneumatized air cells forms the ethmoid sinus medial to the lamina (. Kristin Hayes, RN, is a registered nurse specializing in ear, nose, and throat disorders for both adults and children. Management of orbital floor blowout fractures. Although the bone of the medial wall (the lamina papyracea) is physically thinner than that of the orbital floor, the honeycombed arrangement of the underlying ethmoid air cells gives the medial wall a significant structural advantage over the floor, which is obliged to sit over the cavernously empty maxillary sinus.3, A break without a rupture? A deviated septum may involve part of the perpendicular plate. The lamina papyracea, also known as the orbital lamina of the ethmoid bone, is the principal component of the medial wall of the orbit, and also the lateral surface of the ethmoid air cells. American Cancer Society. Craniectomy. It is believed to be the worlds longest surgery. And to do that, we need a plate that can be cantilevered over the sinus from the rim., In these cases, Dr. Mazzoli said that titanium rim and floor plates and porous polyethylene floor plates have offered wonderful technological improvements over wire, silicone sheeting and calvarial bone.

The V2 nerve that goes to those structures, the infraorbital nerve, passes through the floor. The fact that impacts such as the one suffered by Mr. Encarnacion do not always rupture the globe may suggest that a sophisticated anatomic principle is at work. It articulates: superiorly with the orbital plate of the frontal bone. The ampullae are the vertical components of the canaliculi and are located directly beneath the puncti. The position of the globe within the orbit is a valuable measure to obtain. The surgical entry of choice depends on the severity of the fracture and concomitant ocular trauma. The anterior wall is formed by the nasal bones and nasal process of the frontal bone. Lamina papyracea is Latin for paper-thin, which is an appropriate term to describe this thin sheet or paper-like osseous structure.

A gift from our ancestors? Survival Rates for Nasal and Paranasal Cancers. Nasal Polyps. study [11]. In young people in particular, Dr. Mazzoli said, the bones arent quite as brittle as in older people, and so are less likely to produce a clean break. The pretarsal, preseptal, and orbital orbicularis fibers insert onto the anterior limb. Interestingly, the larger fractures are actually less likely to entrap tissues. Once the body is injured, it starts healing immediately. anteriorly with the lacrimal bone. The correction of traumatic telecanthus is one of the most difficult challenges in bony facial trauma surgery. When the medial wall (lamina papyracea) is fractured, the medial rectus becomes entrapped, leading to lateral gaze dysfunction. Reiss B, Rajjoub L, Mansour T, Chen T, Mumtaz A. The axial views are useful in evaluating both walls of the frontal sinus. Deviated Septum. If there is stable bone on the contralateral side the medial canthal tendon can be looped with a 28 ga. wire and secured to bone on the opposite side.

Our patient had normal eye movements and vision on subsequent eye examinations. Joel S. Glaser. Who treats nasal cavity and paranasal sinus cancers? This patient underwent urgent repair with the placement of an orbital floor implant. pain with extraocular muscle movement, ecchymoses, and periorbital edema. Medial Wall: lamina papyracea and ethmoid bones Lateral Wall: zygoma and sphenoid bones Inferior Wall: zygoma and maxillary bone Note: Significant force applied to the nasal bridge can result in naso-orbito-ethmoid fractures and these are usually accompanied with intracranial injury. If a CSF leak is present the CT may provide information on its location, the most likely area will be the cribriform plate or fovea ethmoidalis.
