Which of the following is not an advantage of marsupialisation
1) Exposure of very little bone
2) Preservating of vital structure
3) Rapid healing
4) Conserve surgical structures
Oral Surgery
Answer: 3
Marsupialization is a surgical procedure often used for cysts or abscesses. While it does have several advantages, such as minimal exposure of bone and preservation of vital structures, it is not typically associated with rapid healing. The healing process can be prolonged compared to other surgical techniques because it involves creating a permanent opening for drainage, which may take time to close completely.
