In cases of post-traumatic V2 hypoesthesia, imaging is warranted. For really large fractures, some surgeons will add a transantral exposure, pushing soft tissues up into the orbit from one direction while pulling them up from the other., Dr. Braverman agreed. 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.

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. In most cases, swelling and discoloration begin to go away within seven to 10 days after the injury, but fractured bones take much longer to heal.

Somethings got to give, and the weakest points are the floor and medial wall. The medial wall is formed by the maxillary bone, ethmoid bone, lacrimal bone, and lesser wing of the sphenoid. Sometimes the floor is so devastated that all you have is a huge communication between the socket and the sinus below, Dr. Mazzoli said. WebConclusion: The classification of lamina papyracea blowout fracture facilitates the judgement of patient's condition and the selection of treatment. It is primarily composed of the lacrimal bone anteriorly and the orbital plate of the ethmoid bone posteriorly. Orbital emphysema was also seen (red arrow). A CT orbit study was ordered to evaluate for an orbital fracture given the acute onset of suspected orbital emphysema after a Valsalva-like maneuver. This probably results from a loosening of the fixation wire or disruption of the medial canthal tendon at the point of fixation with the wire. 2002 May;12(5):1127-33. Freund M, S. Hhnel S,Sartor K.

A paper-thin area of the orbital wall (lamina papyracea), the most common site of the bony defect, allows air to pass from the medial paranasal sinuses to the orbit. A formal ophthalmological evaluation should be performed to assess baseline ocular function. It articulates: superiorly with the orbital plate of the frontal bone. A blow-out fracture occurs when a blow to the eye increases pressure in the orbit, causing the weak floor or the medial wall (lamina Publication types English Abstract MeSH terms Adolescent Adult Aged Child In: StatPearls [Internet]. She complained of diplopia and pain on eye movement. It is a fleshy nodule that contains sebaceous and sweat glands that help maintain normal ocular physiology. 29 23. Knowledge of the soft tissue anatomy of the medial orbit is necessary to safely and effectively manage medial orbital wall fractures without inadvertently injuring surrounding critical structures. Other symptoms associated with an NOE fracture include: When visiting a healthcare provider to be evaluated for sinusitis, you may never be told which sinus(es) are inflamed or infected.

The inclination might be to send the patient home with ice compresses, but you want to think about the mechanism, the energies and directions of the insult. It thickens posteriorly to form the optic tubercle, protecting the optic nerve. Intraorbital air, also known as orbital emphysema, is visible by a hypodense signal that appears as a black, rounded space. The mucus that is produced in the sinus cavities lines this part of your nose, which also serves as a defense mechanism by trapping any particles that may cause illness or other reactions. Prevalence of Diplopia and Extraocular Movement Limitation according to the Location of Isolated Pure Blowout Fractures. The inferior rectus was significantly displaced and rounded, extending into the maxillary sinus (yellow arrow). Our patient had normal eye movements and vision on subsequent eye examinations.

Andrey is a coach, sports writer and editor. Nicholas Jones. A new study found that cells in the body actually respond to pain. If you continue to use the site, we will assume that this suits you. Lamina papyracea is Latin for paper-thin, which is an appropriate term to describe this thin sheet or paper-like osseous structure. In my mind, the indications for fixing a floor fracture, said Dr. Custer, are if the patient has double vision related to probable muscle or soft-tissue entrapment, or if they have cosmetically or functionally significant enophthalmos. [7] Frontal Sinus The plica assists in normal tear function and facilitates movement of the globe (. 4. Sinus cavities in the ethmoidal labyrinth help serve many important functions, including: The nasal conchae that the ethmoid forms allow air to circulate and become humidified as it travels from your nose on the way into your lungs. Disruption of the anterior and/or posterior ethmoid arteries contributes to hemorrhage in the setting of medial orbital wall fractures. Really sweet. ___________________________, 1 Vinger P.

Orbital floor fractures (or blowout fractures) Sometimes, an orbital floor fracture creates a small opening in the bone. Your healthcare provider may also use a fiber optic scope to visualize inside your nose and sinus cavities. These structures are closely related to the orbital processes of the frontal, sphenoid, maxillary, and palatine bones. 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. Otolaryngol Head Neck Surg 2003; 129:43. If clear fluid is present it should be collected and sent for glucose levels with a simultaneous blood sample. 2010;24(4):383-388. doi:10.1055/s-0030-1269767, Ha YI, Kim SH, Park ES, et al. Anatomy, Head and Neck, Nose Paranasal Sinuses.

The fragility of the orbital floor is eloquently considered in a chapter from Ophthalmic Care of the Combat Casualty, coauthored by Dr. Mazzoli. You have mild to moderate symptoms lasting 10 days or more. A piece of bone may break off and be pushed in the direction of the blow. It delineates the most posterior portion of the medial orbital wall and defines the optic foramen in the orbital apex. Treasure Island (FL): StatPearls Publishing; Knipe Hm St-Amant M, et al. The thin curved central area of this bone is referred to as the lamina papyracea. Due to its thin nature, most medial orbital wall fractures occur through the lamina papyracea, as opposed to the thicker anterior and posterior portions of the medial orbit. The concentration of glucose in CSF is usually greater than or equal to 50 mg%. They have a blowout, with entrapment, but perhaps without many signs, such as swelling, ecchymosis or hemorrhageso the eye is white and quiet even in the presence of a fracture. WebEvidence of an orbital fracture may be obvious or elusive. Superior limb: The superior limb of the medial canthus extends over the lacrimal sac and covers its anterior and superior portions. Zygomaticomaxillary complex, frontal sinus, and orbital fractures can lead to orbital infection and preexisting sinus disease appears to contribute to the risk of infection. Disruption of the medial canthal tendon from its bony insertions can have a significant deleterious effect on ocular function and aesthetics (. Arch Ophthalmol 1999; 117(3):354358. I always tell my residents to ask the patient What were you hit with? This patient underwent urgent repair with the placement of an orbital floor implant. inferiorly with the maxilla and orbital process of the palatine bone. Plain film radiography is of limited value in the assessment of medial wall fractures, although disruption of the medial orbit and opacification of the ethmoid sinus can sometimes be detected on x-ray. Fractures may be described as displaced or non-displaced, depending on the fractured bones alignment with the adjacent bone. Open surgery on the heel bone. It is also the thinnest portion of bony orbit.

The orbital floor, in fact, may actually be more likely to fail before the globe ruptures. If the bone on the opposite side is also fractured and not stable the best method of securing the medial canthal tendon is to place a small screw into the bone of the contralateral anterior, superior orbital wall and tightening the wire around that screw. In those cases, consider inquiring about new onset numbness or loss of sensation in the upper teeth or lip. Method: A clinic analysis was made on 108 case with lamina papyracea blow-out fracture. According to the classification, different treatments were taken differently. Result: The classification of 108 cases were reported as follows: 71 cases were classified as level 1, 33 cases as level 2, 4 cases as level 3. Clin Ophthalmol. Ocular trauma is common, and ODs should be familiar enough with orbital fractures to assess the need for imaging and referral. The glucose oxidase test on which these are based is quite sensitive and will be positive at values under 20 mg% (38). Know orbit anatomy and how and when to image ocular trauma. Of note, patients may not complain of diplopia if they have significant eyelid edema obstructing the visual axis, so gently holding eyelids open during motility testing can be helpful. Case 2. Sinusitis, which is a bacterial or viral infection or allergic reaction in the sinuses, can cause a sensation of orbital or eye socket pain.
