Q

Why in arthroscopy is it only the upper joint cavity space we access

A

This is because the lower space is more difficult to access without their being risk of damage to the articular disc

16
Q

Name 5 managment strategies of someone complaining of TMJ pain and dysfunction

A

Reassurance and explanation of condition to the patient
Jaw rest and soft diet
Analgesic advice
Occlusal splints to interfere with parafunction
Physiothepry
Muslce relaxants
Supported yawning, no chewing gum, dont chew on pencils
Local measures ; cold compresses or heat pad

17
Q

Where does the articular disc normally sit

A

In the anteior aspect of the condylar head

18
Q

Define internal derangement

A

Abnormality in position of the articular disc that interferes with function and may be associated with other symtoms

19
Q

What the most common type internal derangement

A

Anteior disc displacement

20
Q

What is disc displacement with reduction

A

Reduction means that a displaced disc reduces into a normal position on opening but reverts back to an abnormal positioning on closing

21
Q

What clincal features would you see in disc displacement with reduction

A

Clicking!!! - on opening and closing
Deviation of the maidble

22
Q

What is disc displacement without reduction

A

If there is no reduction a displaced disc remains in the displaced position regardless of the state of opening

23
Q

What clinical features may be seen in disc displacement without reduction

A

No click !!
Reduction in opening
Pain in front of the ear

24
Q

When is surgery indicated for TMD

A

Surgery is only indicateed where non surgical methods have failed and the Symtoms are severe

25
Q

What is arthocetesis

A

Involves lavage ( washing out) of the upper joint space using hydraulic pressure and manipulation to release adhesions

26
Q

What is meniscoplasty

A

Procedure to responsition the articular disc
Capsule opened, disc visualised and sutured into place

27
Q

What is menisectomy

A

The disc may be removed if it cannot be reposition due to deformity or degeration

28
Q

What are some factors associated with the development of chronic TMD pain and a worse prognosis

A

Being female
Increasing age at presentation
Co morbid psychological factors ; anxiety or depression
Poor coping skills

29
Q

What kind of approach should be taken when managing paitents with TMJD

A

Bio-psychosocial approach

Takes into account the pathology and psychology associated with it
Pyschological side of it tends to affect the pain

30
Q

Simple analgesia and NSAIDS can be advised for patients with TMD however what other medications could be tried if symptoms severe

A

Short course of benzodiazepine i.e diazepam 2mg 3x daily max 2 weeks

A trial of amitriptyline or Gabapentin

31
Q

What may be seen intra-orally in a patient with TMD

A

Linea alba
Scalloping of the tongue
Signs of toothwear

32
Q

What are factors that can affect peoples pain

A

Age
Previous or current mental health diagnosis
Anxiety/ stress
Habits
Previous traUMA

33
Q

What are the aims of a splint in TMJD

A

Dissoccluding the occlusion
Protecting the teeth

34
Q

What are the 4 basic principles of TMJD

A

Muscular - initiation
Mehchanical - Tmj dysfunction
Psychological - underlying cause
Trauma - aetiology

35
Q

The articular cartilage is made up of chrondroblasts and collagen fibres in a proteoglycan matrix
How can inflammatory disease affect this

A

Inflammatory disease produces proteases which degrade the proteoglycans

36
Q

What has to be the first stage in conservative management if the TMD is caused by a habit

A

Counselling - if a patient cannot stop their habit no treatment will be useful

37
Q

What are three functions of a bite raising appliance

A

Elimates occlusal interference
Prevents the joint head from rotating so far posteriorly in the glenoid fossa
Reduces load on TMJ

38
Q

What is an arthogram

A

Injecting Radiopaque material around condyle to look at upper and lower compartment
- this allows us to see the integrity of the disc and if there is a perforation

39
Q

When inside the upper joint space during an arthroscopy - what may we see that indicates to us that there is inflammation

A

Varicose veins - if there is can do cauterisation
