Q

Describe the pathogenesis of BPPV

A

T h e re is displacement of an otolith /otoconia within the
semicircular canals. The heavier otolith causes abnormal
movement o f the endolymph within the canal, giving the
sensation o f vertigo.

    in the parotid gland? (1)
  4. What is the commonest tumour of the parotid gland? (1)

A

Retropharyngeal abscess

27
Q

28
Q

Mx of epistaxis?

A
  1. A to E
  2. Fluid resus, analgesia
  3. Pinch fleshy part of nose and lean forward
  4. Apply pressure for 20 min
29
Q

3 treatment options for epistaxis?

  1. packing
  2. cauterisation
  3. foley catheter
30
Q

Complications of epistaxis?

A

septam haematoma
sinusitis
deformity
vasovagal episode
aspiration

31
Q

Signs of OME?

A

dull, retracted tympanic membrane with loss of light reflex
air bubbles/fluid level behind membrane

32
Q

What predisposes children to OME?

A

Down’s/cleft palate

33
Q

what is adjuvant therapy

A

Adjuvant therapy is given after the tumour has been removed surgically, with the aim of destroying any remaining tumour cells.

34
Q

what pathophysiological change is seen in the ears in Meniere’s?

A

endolymphatic hydrops

35
Q

Meniere’s Tx?

A

acute attacks: buccal or intramuscular prochlorperazine. Admission is sometimes required

prevention: betahistine and vestibular rehabilitation exercises may be of benefit

36
Q

complications of OM?

A

● Meningitis. ● Hearing loss. ● Mastoiditis. ● Tympanic membrane perforation. ● Intracranial abscess. ● Facial nerve palsy.

37
Q

Stone in salivary gland - Dx?

A

● Fine-needle aspiration. ● CT. ● X-ray. ● Sialogram.

38
Q

Clinical signs of quinsy?

A

● ‘Thick’ voice. ● Swelling adjacent to the tonsil. ● Trismus. ● Snoring. ● Bulging of the soft palate. ● Tonsillar arch pushed forward. ● Deviated uvula. ● Erythema of arch and palate.

39
Q

definitive Mx of quinsy

A

aspiration of abscess, incision and drainage

40
Q

complications of untreated quinsy

A

● Airway obstruction. ● Death. ● Deep neck-space infection. ● Mediastinitis.

41
Q

swelling near ear + facial droop =

A

adenoid cystic carcinoma

42
Q

Tx of benign parotid tumour?

A

Superficial parotidectomy to spare the facial nerve.

43
Q

what is Frey’s syndrome?

A

Frey’s syndrome happens when you experience facial sweating and flushing when you eat. It’s often a side effect of parotid gland surgery and happens due to nerve damage and abnormal nerve regrowth.

44
Q

How should septal haematoma be managed?

A

urgent incision and drainage

45
Q

Nasal fracture management?

A
  1. Give 5-7 days for swelling to subside then see in clinic
  2. Manipulation under anesthetic 7-14 days after injury
46
Q

Clear discharge from nose which tests positive for beta-2 transferrin - what is it? What should be done now?

A

CSF
Manage it conservatively

47
Q

Pain + swelling in ear suggestive of pinna haematoma - Mx?

A

aspirate immediately, risk of avascular necrosis of cartilage

48
Q

What is a cholesteatoma?

A

A cholesteatoma is an overgrowth of keratinised squamous epithelium in the middle ear, in the ‘attic’ of the ear.

49
Q

Complications of a cholesteatoma?

A

● Facial nerve palsy. ● Meningitis. ● Abscess. ● Deafness. ● Recurrence. ● Mastoiditis. ● Sigmoid sinus thrombosis. ● Labyrinthine fistula. ● Osteomyelitis. ● Chondritis.
