Ch. 11 F.B., Nasal, and Orbits Pathology Flashcards
severe bilateral horizontal fractures of the maxillae that may result in an unstable detached fragment
Le Fort fracture
a fracture to one side of a structure that is caused by an impact on the opposite side, ex. mandible
contrecoup fracture
an infection of the sinus mucosa that may be acute or chronic. Patient complains of headache, pain, swelling over the affected sinus and possibly a low-grade fever
sinusitis
hemorrhaging of blood from a ruptured artery or vein causing a collection of blood
hematoma
a localized infection of bone or bone marrow, infection may be caused by bacteria from a penetrating trauma or postoperative or fracture complications. also may be spread by blood from a distant site
osteomyelitis
describes a set of symptoms, which may include pain and clicking that indicate dysfunction of the TMJ. condition may be caused by malocclusion, stress, muscle spasms, or inflammation
TMJ syndrome
caused by a blow to the cheek, resulting in fracture of the zygoma in 3 places - orbital process, maxillary process, and arch. result is a “free-floating” zygomatic bone
tripod fracture
an infection of the bone and marrow secondary to sinusitis, results in erosion of the bony margins of the sinus
secondary osteomyelitis
what best demonstrates most blowout fractures
modified waters (OML 55 degrees with the film; LML perp to IR)
fracture of the floor of the orbit caused by an object striking the eyes straight on. As the floor of the orbit ruptures, the inferior rectus muscle is forced through the fracture into the maxillary sinus, causing entrapment and diplopia (perception of 2 images) may also include the medial walls of the orbit
blowout fracture
congenital defect in which the two palatine processes of the maxillae don’t unite
cleft palate
a severally pushed to one side nasal septum
deviated (nasal) septum
