To perform tracheostomy entry should be made at the
1) Cricothyroid ligament
2) Thyroid membrane
3) Thyroid notch
4) Cricoid cartilage
Oral Surgery
Answer: 1
A tracheostomy is a surgical procedure that involves creating an opening in
the trachea (windpipe) to facilitate breathing. The preferred site for making
the incision during a tracheostomy is the cricothyroid ligament,
which is located between the cricoid and thyroid cartilages.
Cricothyroid ligament: This ligament is relatively
superficial and provides a safe access point to the airway, especially in
emergency situations. It is often chosen for emergency tracheostomy because
it is easier to locate and access quickly.
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.

1) Administration of antibiotics
2) Application of hot packs to the area
3) Incision and drainage
4) Antibiotics administration followed by I & D
Oral Surgery
Answer: 3
The treatment of choice for a patient with a localized infection and pus formation, especially if they are afebrile (without fever), is incision and drainage (I & D). This involves creating a small opening in the skin to allow the pus to drain out. While antibiotics can be used as an adjunctive therapy to prevent the spread of infection, they are not always necessary in the initial management of a localized abscess if it is managed effectively with I & D.
