Q

indications for marsupialization …

A

indications for marsupialization …

  • To prevent injury to adjacent structures
  • To prevent devitalization of teeth
  • To assist in the eruption of teeth
  • Where there is difficult surgical access
  • Where there is a risk of pathologic fracture
  • In the medically compromised patient
    • Short surgical procedure
    • Local anesthesia
  1. Decreased risk of fracture No risk to the IA nerve
  2. Useful teeth can erupt
75
Q

A
  1. aneurysmal bone cyst
  2. fibro-osseous lesions
  3. giant cell granuloma
