Q

aetiology

A

genetic -

  • syndromes,
  • FH,
  • sex ratio,

  • ethnic distribution

environmental

  • social deprivation,

Q

implications - speech

A

sound production or articulation problem
levator veli palatini - prevents air escaping through nose when you speak as soft palate against pharynx
- resulting in hypernasality

Q

implications - hearing

A

face forms from brachial arches (1st and 2nd)

  • ears forms from BA as well
  • if cleft involves a craniofacial structure there is a good chance it will affect your hearing
    also pressure in middle ear doesn’t get equalised so more prone to infections

respiratory

20
Q

pt journey stages UCLP

A
  • lip closure - 3mo
  • palate closure - 6-12mo
  • alveolar bone graft - 8-10year
  • definitive orthodontics- 12-15 yr
  • surgery - 18-20yr

first 3 compulsory

21
Q

lip closure

A

around 3m

stronger to cope with GA

22
Q

palate closure

A

around 6-12m

start to babble around 12m so make palate as normal as possible by then

23
Q

alveolar bone graft age

A

around 8-10 years

24
Q

definitive ortho

A

around 12-15 years

often slightly slower at getting teeth through

25
Q

surgery age

A

around 18-20years

26
Q

when can nasal surgery be done from?

A

15 years - nasal growth completed

27
Q

how do the clinics correspond to tx stages?

A 
baby MDT - newborn
children's clinic - 0-7 years
bone graft clinic - 7-12 years
transition clinic 12-16years
adult clinic 16+ years
28
Q

dental issues

A 
missing teeth
impacted teeth
crowding
growth
caries
29
Q

Most common missing teeth

A

lateral incisor

30
Q

dental issue -caries

A

due to hyperplastic teeth

31
Q

dental issues - impacted teeth reason

A

supernumeraries

32
Q

dental issues - crowding

A
  • usually U arch
  • problam of relapse
33
Q

dental issues - growth

A 
maxilla doesn't tend to grow well
often develop into a class 3 occlusion
34
Q

dental cleft team

A 
paediatric dentist
dental therapist
orthodontist
orthodontic therapist
restorative dentist
oral surgeon
35
Q

orthodontic tx stages

A

pre-surgical orthopaedics
expansion/bone grafting
definitive orthodontics
orthognathic surgery

36
Q

pre-surgical orthopaedics

A

not v common now
strapping
dento-alveolar moulding (pre-surgical ortho plate)
no evidence they work

37
Q

pre-surgical orthopaedics - strapping

A

try to reduce gap between cleft segments
should make surgery easier as less scarring
Dyna cleft - tension on lip and palate

38
Q

pre-surgical orthopaedics - dento-alveolar moulding (pre-surgical ortho plate)

A

theories
- if you cover palate with plate it is easier to suckle and feed
- tongue wouldn’t sit high up so segments would come together
but have to take imps - <6m obligate nasal breathers
- alginate blocks their nose - asphyxiation
- try to suckle alginate - down palate

39
Q

why is expansion/bone grafting needed?

A

you have closed the lip and palate but still have hole across alveolus
teeth want to erupt
purpose is to allow the teeth to erupt into the arch so you can do ortho

40
Q

timing of expansion/bone grafting

A

want canine to erupt into bone graft site to maintain the bone
around **9 years **- timed around canine
take radiograph 7years to see what is developing around the cleft site

41
Q

when would you usually remove any supernumeraries?

A

about 3m before bone grafting/expansion surgery

42
Q

why would you have braces before expansion/bone grafting surgery?

A

only if access to the cleft site for the surgeon is difficult

historically was routinely done

43
Q

expansion/bone grafting surgical technique

A

bone from hip (similar) - cancellous bone so good blood supply
flaps - need to use attached mucosa otherwise teeth wont erupt through it

44
Q

when would you radiograph after expansion/bone grafting and why?

A

6m to ensure bone there

45
Q

what does definitive ortho tx depend on?

A 
bone graft - need roots in the bone graft to maintain it
aesthetics
growth - often grow class 3
 - pt may be happy leaving with slight class 3 incisors?
46
Q

how does aesthetics affect definitive ortho tx?

A 
teeth often narrow
missing lateral incisor
central incisor hypoplastic and small
lip line often lower
aesthetics of nose tend to be more obvious than teeth
47
Q

why can orthognathic surgery be difficult?

A

lack of bone
tooth position
issue - if move jaw forward can make it hard for soft palate to hit pharynx
- hypernasality esp if had issues before surgery
