Oral-Maxillofacial
| Question | Answer |
|---|---|
| Procedures involving _____________ are performed primarily by oral-maxillofacial surgeon. | Teeth |
| ___________ Implants are placed beneath the periosteum directly on the alveolar bone. This type of implant is used primarily when bone is insufficient to support an endosteal implant. | Subperiosteal |
| Midface advancement is performed to correct a bony deformity of the | Maxilla |
| The face is divided into what 3 parts? | Upper Face, Midface, Lower face |
| _______________ Congenital defect resulting in a small lower jaw. This can affect feeding in the infant and alignment of the teeth as the infant grows | Mandibular Micrognathia |
| Facial fractures are prepped with Betadine scrub and paint. The entire face is prepped, from the hairline to the _____________ | Sternal notch |
| ____________________ are implanted to realign dentition of the mandible and midface. | B. Arch bars |
| Le Fort _____ is a horizontal fracture of the maxilla that causes the hard palate and alveolar process to become separated from the remainder of the maxilla. The fracture extends into the lower nasal septum, lateral maxillary sinus, and palatine bones. | I |
| Complications of include extrusion of the globe into the nasal sinus and entrapment of the eye muscles | orbital floor fractures |
| ___________ is characterized by persistent pain and is usually associated with stress related muscle tension and grinding of the teeth (bruxism), malocclusion, trauma, or arthritis. | TMJ disease |
| _____________________ focuses on reconstruction and repairs of the facial bones and may include structures of the oral cavity | Oromaxillofacial surgery |
| Patients frequently experience _________________ immediately after surgery to repair orbital floor fractures because of the use of the corneal shield and the antibiotic ointment. | blurred vision |
| Before repair of frontal sinus fractures, the sinus mucosa must be removed and the duct occluded. The sinus is then often filled with a __________________ | Fat Graft |
| ___________ dictate(s) that wires on arch bars be tightened in a clockwise fashion so that any other surgeon knows to remove them in a counter-clockwise direction. | Standard protocol |
| ________________ are performed primarily by oral-maxillofacial, plastic, or otorhinolaryngology surgeons | Maxillofacial procedures |
| In the Le Fort ___ fracture there is a separation of all the facial bones from their cranial base. It includes fracture of the zygoma, maxilla, and nasal bones. | III |
| Plain x-ray is used for baseline assessment or for simple fractures. However, extensive tissue swelling may obscure complex anatomical features and injuries. __________ is therefore performed for complex facial fractures and reconstruction procedures. | CT scanning |
| One of the fundamental goals of any maxillomandibular procedure is to preserve the patient's _________ between the mandible (lower jaw), maxilla, and midface bones. | Unique bite pattern |
| ________ of injury or congenital anomalies can affect speech, mastication (chewing), and development of the teeth | Long-term physiological effects |
| The Le Fort _______ fracture is pyramidal. It extends from the nasal bone, to the frontal processes of the maxilla, lacrimal bones, and inferior orbital floor, and may extend into the orbital foramen. | II |
| The _________ forms the bridge of the nose and articulates with the ethmoid and maxilla. | Nasal bone |
| The _________ is the only movable bone of the face. | Mandible |
| _______ are the primary means of repairing facial fractures. | Plates & Screws |
| The _______ must keep track of all plates and screws that are used during surgery for the purposes of charging and documentation. | Scrub |
| If a _____________ is planned, the patient's head may be shaved, and the prep carried from the posterior head to the sternal notch. | bicoronal incision |
| Surgery involving the bones of the face, primarily for repair of fractures and reconstruction for congenital anomalies, is defined as _______________ | Oral-maxillofacial surgery |
| ___________ is the number, type, and pattern of the teeth. | Dentition |
| A screw that penetrates both cortical layers and the intervening spongy layer of the bone is called a ________ screw. | Bicortical |
| 29. Also called application of arch bars, a procedure in which the maxilla and mandible are placed in their normally closed position and fixed with wires is called ______________ | Maxillomandibular fixation (MMF) |
| The __________ forms the lateral walls and floor of the bony orbit, which houses the eyeball | Zygoma |
