Q

What presents as
Mixed density lesion, benign and slow growing usually involving developing tooth

A

calcifying epithelial odontogenic tumour

19
Q

What presents as a radiolucency beneath the inferior alveolar nerve

A

Stafne bone cyst

20
Q

What cysts are non-epithelial lined

A

aneurysmal bone cyst
solitary bone cyst

21
Q

What cyst slowly expands, aggressive, cyst like lesion, typically contains blood filled spaces

A

aneurysmal bone cyst

22
Q

how does a solitary bone cyst present

A

non-epithelial lined, incidental
- vital tooth
sometimes contains blood-stained serous fluid/ gas

aetiology: unknown, potential trauma
peaks 2nd decade

23
Q

What epithelium do nasopalatine cysts dervive from

A

epithelial remnants of Jacobson’s organ

24
Q

What is the mechanism for the formation of nasopalatine cyst

A
  1. entrapement of epithelium (remnant spof jacbsons organ) during embrylogical fusion of maxilla
  2. stimulated by trauma, bacterial infections and retention of mucous
25
Q

How do nasopalatine cysts present

A

well defined, round, ovoid/ heart shaped

26
Q

What presents as an inverted pear shape radiolucency between laterals and canines

A

Globulomaxillary cyst

27
Q

What presents as a midline radiolucency that is an inverted pear

A

Medial palatal cyst

28
Q

What presents as a radiolucency between roots of teeth & scalloped appearance

A

solitary bone cyst

29
Q

How does aneurysmal bone cyst present

A
  • uni/ multilocular
  • irregular outline- soap like appearance
  • displace roots
30
Q

What epithelium do sublingual dermoid & dermoid cysts arise from?

A

retention of germinal epithelium (embryonic process)

31
Q

How do sublingual/ dermoid cysts present

A

deep, filled with keratin, slow growing and can affect speech/ swallowing

32
Q

what do brachial cleft cysts arise from

A

second brachial cleft

33
Q

How do brachial cleft cysts present

A

USUALLY SIDE OF NECK loor of mouth/ posterior tongue
- asymptomatic (lateral aspects of neck, anterior border of sternocleidmastoid)

typically young children/ adults- tonsilar. base

34
Q

what are thyroglossal cysts derived from?

A

thyroglossal duct due to foramen cecum migrating down to thyroid gland

35
Q

How does a thyroglossal cyst present and how is it diagnosed

A

midline swelling

diagnosis:
- swallow & protrude tongue- see how it moves
- thyroid scan

36
Q

Where do mucous retention/ mucous extravasation cysts arise from?

A

salivary gland tissue

37
Q

How does a plunging ranula present

A

extends through mylohyoid & neck
- affect speech and swallowing
- exicison with intra-oral and extra-oral
- use of MRI to aid

38
Q

what does mckechnie mean when he says rationale

A
  • underlying problem
  • consequence of underlying problem
  • how does tx address the problem
39
Q

What are the benefits for decompression

A
  • low risk
    -preserves vital structures
  • preserves teeth
40
Q

What is meant by ‘decompression’

A

Opens a window into the cyst- place a plastic tube & reduces size of lesion

41
Q

What are the risks associated with decompression

A
  • hygiene
  • compliance
  • sometimes tricky
  • second procedure maybe needed
42
Q

What is enucleation

A

removal of the lesion in its entirety

43
Q

What are the benefits of enucleation

A
  • entire specimen is removed so it is curative
44
Q

What are the risks of enucleation

A
  • surgically challenging
  • need to preserve vital structures
  • risk of pathological fracture
