Q

If you see a soap bubble appearance in the posterior mandible and the differential is myxoma or ameloblastoma, what is the age consideration that can place one above the other on the differential?

A

Ameloblastoma in 30-70 yr olds

Myxoma common in 20-30 yr olds

Q

A central giant cell lesion occurs most commonly before what age?

A

30 years old

17
Q

When you get a giant cell histology back, what is the other systemic consideration for the differential?

A

Hyperparathyroidism because giant cell is histologically identical to Brown’s tumor of hyperparathyroidism

18
Q

What is the best treatment for a Central Giant cell lesion?

A

Excision and peripheral ostectomy

19
Q

The treatment of benign jaw lesions is based on what?

A

Aggressiveness of pathology and likelihood of recurrence

20
Q

What are 2 consequences of excising a large dentigerous cyst in the posterior mandible?

A
  1. Compromise integrity of mandible

2. Paresthesia

21
Q

To avoid compromising mandibular and integrity and paresthesia (which are consequences of excision), what is another option for treatment of dentigerous cyst?

A

Marsupialization / decompression

22
Q

What are 6 surgical approaches to bony jaw pathology?

A
  1. Simple curettage
  2. Excision with peripheral ostectomy
  3. En bloc resection
  4. Decompression or Marsupialization
  5. Embolization (Vascular lesions)
  6. Chemical Cautery or Cryotherapy
23
Q

What is a surgical approach that after cyst has been enucleated a curette or bur is used to remove 1-2 mm of bone around the entire periphery of the cystic cavity to remove any remaining epithelial cells that could proliferate and cause cyst recurrence?

A

Curettage

24
Q

What is a surgical approach that after cyst is enucleated, use large round burs to remove a good amount of bone (up to 1 cm) from margin of walls?

A

Excision with peripheral ostectomy

25
Q

What is the surgical approach where the feeding artery is catheterized and something is injected to coagulate and cause the lesion to involute?

A

Embolization

26
Q

What is the surgical approach where the feeding artery is catheterized and something is injected to coagulate and cause the lesion to involute?

A

Embolization

27
Q

What is the differential for unilateral palatal swelling?

A
  1. Salivary tumor
  2. Neurogenic tumor
  3. Lymphoma
  4. Maxillary sinus pathology
  5. Metastatic tumor
