21
Q

what is the lateral border of the pterygomandibular space?

A

ramus of mandible

22
Q

what is the medial border of the pterygomandibular space?

A

medial pterygoid muscle

23
Q

what is the posterior border of the pterygomandibular space?

A

parotid gland (and CNVII)

24
Q

what is the anterior border of the pterygomandibular space?

A

buccinator

25
Q

what is the superior border of the pterygomandibular space?

A

lateral pterygoid muscle

26
Q

what is the risk of inferior alveolar nerve block?

A

high risk of IV injection due to neurovascular bundle

27
Q

describe how you find the location of the injection site for inferior alveolar nerve block

A

Thumb in coronoid notch
Lateral to pterygomandibular raphe
1cm above lateral plane

28
Q

what angle should the needle be when giving inferior alveolar nerve block?

A

so syringe is over premolars on opposite side

29
Q

how deep should you insert the needle for inferior alveolar nerve block?

A

till reach bone - about 2.5cm so 1cm left out

withdraw needle by 1-2mm

30
Q

once the needle is in the right place what do you have to do before injecting the LA?

A

aspirate

31
Q

how much LA do you inject for inferior alveolar nerve block?

A

1.5-2ml

32
Q

what do you have to do before you can start treatment after giving IANB?

A

wait for it to work

33
Q

what is a key sign that IANB has worked?

A

if the lip is numb as mental nerve is branch of inferior alveolar nerve

34
Q

what is the injection site for lingual nerve block?

A

same as IANB but 1cm more anteromedial

can often withdraw needle by 1cm, aspirate and inject again to get lingual after IAN

35
Q

what is a key sign that a lingual nerve block has worked

A

half tongue numb

36
Q

what is the risk of buccal nerve block?

A

higher up in the pterygomandibular space so more likely to hit pterygoid venous plexus

37
Q

where is the injection site for buccal nerve block?

A
38
Q

where is the injection site for mental/incisive nerve block?

A

between apices of premolars

39
Q

if you give a mental/incisive nerve block and the lip is numb, what does this tell you?

A

you’ve got the mental nerve but not necessarily the incisive nerve so don’t know if the teeth are numb

40
Q

when do you give mandibular infiltrations?

A

if IAB fails

41
Q

how much LA do you use for a buccal mandibular infiltration only?

A

1ml

42
Q

what is the success rate of mandibular infiltration alone?

A

50%

43
Q

how much LA do you give if doing a buccal and lingual mandibular infiltration?

A

split dose 0.5ml each

44
Q

what is the success rate of a lingual and buccal infiltration together?

A

90%

45
Q

with a lingual infiltration how long do you have to wait for pulpal anaesthesia?

A

8-10mins

46
Q

why would you do molar infiltrations over blocks?

A

Easier, lower risk of IV injection, can make injection more comfortable with topical
