13. Surgical Treatment Flashcards
1
Q
Indications for surgery
A
- Pain
- Hypomobility
- Hypermobility
- Hypofunction
**Not indicated for symptomatic or minimally symptomatic patients or as a preventive measure
2
Q
Goals of surgery
A
- Pain relief
- Improved ROM
- Improved joint function (mastication)
- Ability to obtain dental care
3
Q
Differences between Arthrocentesis and arthroscopy
A
- Both have similar goals and outcomes
- Lysis and lavage= lysis the adhesions preventing disc and joint movement (done by injection of a liquid)
- Indications= closed lock
- Arthrocentesis is blind and arthroscopy uses a camera to see
4
Q
What is an arthrotomy
A
Surgical entry of joint space (either superior, inferior or both joint spaces)
- May or may not include surgery on the disc
- May or may not include bony recontouring of the joint
5
Q
Indications for arthrotomy
A
- Internal derangement
- Arthritis
- Chronic/recurrent mandibular dislocation
- Intracapsular ankylosis
- Condylar malformation
6
Q
What are the two types of ankylosis
A
fibrous and bony
7
Q
Describe the difference surgical approaches
- Preauricular
- Postauricular
- Hemi- or bicoronal
- Risdon (submandibular)
- Retromandibular
A
- Preauricular in front of ear
- Postauricular behind ear
- Hemi- or bicoronal for coronoid fusion from one preauricular site to the other
- Risdon (submandibular) commonly used for mandibular angle fractures
- Retromandibular
8
Q
Define condylectomy
A
removal of the condyle
9
Q
Define condylar shave
A
recontouring the condyle
10
Q
Define eminectomy
A
removal of the articular eminance
11
Q
Difference between autogenous and alloplastic joint replacement
A
autogenous- own rib and alloplastic = fake
12
Q
What is a condylotomy
A
vertical ramus osteotomy
13
Q
Treatments for extracapsular ankylosis
A
- coronoid hyperplasia
- fracture malunion
- complication of skull base surgery
14
Q
Complications
A
- Pain
- Swelling
- Infection
- Limited mandibular movement
- Facial n. injury (temporal and zygomatic branches)
