Q

Where can you find a mucocele?

A
  • In the duct
  • Extravasated in to the tissues (mucous extravasation system)
  • Common to find in lower lip and soft palate (areas of trauma)

Q

What is a Subacute obstruction?

A
  • Swelling associated with the major glands (usually submandibular as duct is longer than parotid)
  • Usually associated with duct blockages either by stones or mucous plugging

Q

With a subacute obstruction what will the pt complain of in regard to the swelling?

A
  • Swelling associated with meals
  • Swelling increases when ot eating as salivary flow starts
  • Swelling decreases when salivary flow stops after meal finished

Q

What is the progression rate of subacute obstruction?

A
  • Slowly progressive over weeks
    -Eventually becomes fixed and painful as gland is blocked and saliva cant escape

Q

In a subacute obstruction what is the difference in outcome between submandibular and parotid?

A

Usually duct blockage in submandibular
- Usually duct structure in parotid

17
Q

What are some causes of subacute obstruction?

A
  • Sialolith (stones)
  • Mucous plugging
  • Ductal damage from chronic infection
18
Q

What does this image show?

A
  • Lower true occlusal radiograph
  • Acceptable
  • Sialoltih (stones)
19
Q

What investigations can be done for subacute obstruction?

A
  • Low does plain radiography
  • Lower true occlusal
  • Sialography (only when infection free as can further push mucous plug into gland and cause worse blocakge)
  • isotope scan if gland function uncertain
  • Ultrasound assessment of duct system
20
Q

What does this image show?

A
  • OPT
  • Shows right side submandibular
21
Q

What does this image show?

A
  • Duct stricture using sialogram
  • Stone in the parotid duct causing a stricture
  • Infection most likely to have cause stone and stricture
22
Q

What does this image show? How does this occur? What childhood disease may cause this?

A
  • Duct dilatation
  • Defects prevent normal emptying
  • Micro0orgs grow and lead to persisting and recurrent sialadenitis
  • Gland function gradually lost and persisting infections lead to gland removal
  • Recurrent Parotitis of childhood
23
Q

What is the management of Subacute obstruction?

A
  • Surgical sialolith removal
  • If no stone present then use Sialograpahy (washing effect)
  • Consider gland removak if fixed swelling
24
Q

what is the outcome of subacute obstruction if not managed?

A
  • Reformation of stone/obstruction
  • Deformity of duct - can lead to stasis and infection
  • Gland damage with low salivary flow, ascending infection
25
Q

What is Sialosis?

A
  • Major salivary gland enlargement with no obvious glandular cause
  • Shows bilateral enlargement with no focal enlargement and generalised diffuse change

Perhaps
- Alcohol abuse
- Cirrhosis
- Diabetes Mellitus
- Drugs
