Surg Tech Oral & Maxillofacial
| Question | Answer |
|---|---|
| The __________ X-ray requires the patient to hyperextend the neck with the nose and chin placed against the cassette so there is good visualization of the facial bones. | Water's view |
| The __________ X-ray is similar but requires the nose and the forehead to be placed against the cassette, which allows better visualization of the orbital floor. | Caldwell's view |
| A plate made of _________ is strong and lightweight and is used most often for craniofacial fractures. | titanium |
| ____________ are used to immobilize the mandibular or maxillary fracture by immobilizing the jaw, increasing the chances of aspiration and requiring liquid nutrition postop. | arch bars |
| Submandibular or preauricular incisions must be made with care to preserve the __________. | facial nerve (VII) |
| Care to locate and prevent nerve damage with orbital floor fractures | infraorbital foramen |
| Located on the mandibular notch of the ramus | mandibular foramen |
| Freely moveable maxilla | Le Fort I |
| Located on the mandible below the first molar | mental foramen |
| Cerebrospinal otorrhea or rhinorrhea may require a fat, muscle, or fascia graft to seal | dural tear |
| Triangular or pyramidal in shape fracture and includes the nasal and ethmoid bones | Le Fort II |
| Postop complication leading to grinding of teeth and posto pain | malocclusion |
| Symptoms include diplopia and enophthalmos due to maxillary sinus invasion | orbital floor fracture |
| Largest and strongest facial bone | mandible |
| Fracture of the malar arches, orbits to base of the nose (nasal, ethmoid, zygomatic) | Le Fort III |
| Basal view | shows zygomatic fractures |
| Panoramic x-ray | shows on one film the alveolar processes, mandible, posterior maxillary sinuses, and zygomas |
| Are oral procedures considered sterile? | no |
| Pt positioning for oral and maxillofacial surgeries | supine with heal tilted back, roll towel may be placed to aid slightly extending the neck - tuck pt's arms and remember to protect ulnar nerves |
| Alias for plastic cheek retractor | "smile maker" :) |
| Double angled retractor that's used for oral surgery | Minnesota retractor |
| Throat pack | dampened rolled raytech - used to prevent oral secretions, irrigation fluid, blood, and bone or tooth fragments from becoming lodged in pharynx |
| Side of tooth that lies closest to lips | labial |
| Side of tooth that lies closest to tongue | lingual |
| Side of tooth that lies closest to cheek | buccal |
| Each tooth is imbedded in a socket of the | alveolar process |
| 3 regions of a tooth | crown, root, neck |
| Crown | portions above gumline |
| Root | portion below gumline |
| Neck | junction of crown and root |
| Crown is covered by ______, which is the hardest part of the tooth | enamel |
| Pulp | contains blood vessels, nerves, and connective tissue |
| Odenectomy | involves resection of the soft tissue and excision of the bone surrounding a tooth prior to removal |
| What should the surgical technologist do before handing a retractor to the surgeon for use in orbital floor fracture? | moisten it with saline for teflon-coated and sterile water for nonteflon-coated |
| Which type of sterile drape is commonly used for oral and maxillofacial procedures? | U-drape |
| What other equipment is used alongside a bone drill? | suction and irrigation |
| Type of suture used to close tooth extraction/odenectomy? | 4-0 chromic or silk |
| Fire safety procedural consideration | endotracheal tube delivers oxygen and is close to operating site - a closed ventilation system, use of a fire-retardant endo tube, and careful use of ESU |
| Open reduction | require use of internal fixation devices |
| The mandible articulates with the _____ ______ of each temporal boen to form the synovial joint called ________. | glenoid fossa, TMJ |
| 3 portions of mandible | body, ramus, angle |
| Body of mandible | contains alveolar process for teeth |
| Ramus of mandible | project upward at an angle from the posterior part of each mandibular body |
| Mental protuberance of mandible | chin |
| Posterior projection of ramus | Condylar process |
| TMJ | contains condylar process, portions of temporal bone, mandibular fossa, and articular tubercle |
| What position are arch bars placed? | upward for upper jaw (maxilla) and downward for lower jaw (mandible) |
| Sequence of plate attachment | 1. drill 2. measure depth of hole 3. drill hole may be tapped 4. screw is placed 5. repeat until plate is firmly fixed to bone |
| What instruments are used for dissection through the infraorbital fat during an orbital floor repair? | curved tenotomy scissors and adson tissue forceps |
| If the orbital reduction is stable, ______ ______ may be inserted over fracture site to prevent entrapment of orbital contents in fracture and support globe | Silastic sheeting |
| If the orbital reduction is unstable, a _______ ______ ______may be implanted, followed by the insertion of Silastic sheeting | rigid fixation device |
| Each nasal bone articulates with the | frontal, ethmoid, maxillary, and opposing nasal bone |
| Zygomatic bones are aka | malar bones |
| Vomer bone | contributes to posterior and inferior portion of nasal septum |
| Chief substance of teeth that is covered by enamel on the crown; harder than bone | dentin |
| Recession of the eyeball within the bony orbit; may be a result of orbital fracture | exophthalmos |
| Angled retractor used for tongue and cheek retraction; shape is similar to a Harrington retractor | Weider |
| Bone plates are available in _____ shapes | L, Y, H, T |
| The hard palate is the ______ _____ of the maxilla | palatine process |
| Anterior projection of ramus | coronoid process |
| Muscle that attaches to coronoid process | temporalis |
