What is a blowout orbital 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. Getting hit with a baseball or a fist often causes a blowout fracture.
What is lamina papyracea?
The lamina papyracea (LP) is the weakest point of the medial wall of the orbit, which forms a connecting line between paranasal sinuses and the orbit. Also, the ethmoidal foramina along the LP are life-saving anatomical landmarks and allow transverse passage of the ethmoidal arteries into ethmoidal cells.
Which wall of orbit is involved in a blowout fracture?
Inferior blow-out fracture In children, the fracture may spring back into place (see trapdoor fracture). Most fractures occur in the floor posterior and medial to the infraorbital groove 2. In ~50% of cases, inferior blow-out fractures are associated with fractures of the medial wall 3.
What part of the bony orbit does a blowout fracture affect?
In blowout fractures, the orbital walls are involved and usually orbital floor undergoes fracture in most cases. Combined orbital fractures usually involve the orbital rim along with walls of orbit and may also involve the conical posterior part of the orbit in case of severe trauma.
What is a lamina papyracea fracture?
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 papyracea) to “blow out” into the maxillary sinus or ethmoid bone. [4, 5, 6, 7, 8, 9, 10] This results in a fracture, although it often prevents globe rupture and loss of the eye.
Is a blowout fracture serious?
Eye injuries resulting from orbital blowout fracture This is a very serious eye injury requiring hospitalization, bed rest, bilateral patching of the eyes, and sedation. This condition usually resolves itself within a few days.
What is lamina papyracea fracture?
Where is lamina papyracea located?
the ethmoid bone
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.
What bones are involved in a blowout fracture?
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.
What is a lamina Papyracea fracture?
Which orbital bone is the most common site of the most blowout fractures?
Most commonly the inferior orbital wall i.e. the floor is likely to collapse, because the bones of the roof and lateral walls are robust. Although the bone forming the medial wall is thinnest, it is buttressed by the bone separating the ethmoidal air cells….Orbital blowout fracture.

What causes lamina papyracea fracture?
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 papyracea) to “blow out” into the maxillary sinus or ethmoid bone. This results in a fracture, although it often prevents globe rupture and loss of the eye.
Is surgery needed for a blowout fracture?
Most simple blowout fractures do not require surgical repair and do not cause lasting problems. Immediate treatment consists of: ice to decrease swelling. decongestants to aid in the drainage of blood and fluid accumulating in the sinuses.
What is the right lamina papyracea?
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.
What causes a blowout fracture?
Do blowout fractures require surgery?
How do you fix a blowout fracture?
What can be done for a simple blowout fracture?
- ice to decrease swelling.
- decongestants to aid in the drainage of blood and fluid accumulating in the sinuses.
- avoidance of nose blowing to prevent pressure from propelling the sinus contents into the orbit.
- oral steroids in some cases to decrease swelling and scarring.
