For midface, orbital, and frontal sinus fractures, the plates and screws are _____.

A

1 to 2 mm

31
Q

What is used to prep facial fractures?

A

Betadine scrub and paint

32

36
Q

What sponges are used during maxillofacial surgery?

A

4 x 4 and cottonoids

37
Q

What is a fundamental goal of any maxillomandibular procedure?

A

38
Q

What must be kept with patients that have arch bars?

A

wire cutters

39
Q

Arch bars are sutured into place using _____.

A

24- or 26- stainless steel suture wires

40
Q

When applying arch bars, the stainless steel suture is twisted into a _____ loop.

A

clockwise

41
Q

Fractures of the midface are reduced and fixated and the buttressing structures are reinforced.

A

open reduction/internal fixation: midface fracture

42
Q

What type of fracture is also associated with leakage of cerebrospinal fluid (CSF) into the nasal sinuses?

A

Le Fort II fracture

43
Q

What are weight-bearing structures of the face?

A

buttresses

44
Q

Performed to repair CSF leakage, prevent obstruction or the frontal sinus ducts, and restore an aesthetic contour to the forehead.

A

open reduction/internal fixation: frontal sinus fracture

45
Q

Fractures of the psoterior wall of the frontal sinus may result in _____.

A

CSF leakage or herniation of brain tissue

cranialization of the sinus

47
Q

What solution is a fat graft placed into to keep it moist until the surgeon is ready to place it in the frontal sinus?

A

normal saline

Q

What are the three types of dental implants commonly used?

A
  • endosteal implant

Q

Placed beneath the periosteum directly on the alveolar bone. Used primarily when bone is insufficient to support an endosteal implant.

A

subperiosteal implant

Q

Bone plates with retaining posts. Used only when the patient has severe loss of bone in the mandibular alveolar ridge.

A

transosteal implant

58
Q

Performed to correct a bony deformity of the mandible.

mandibular advancement

59
Q

Performed to correct a bony deformity of the maxilla.
