Compbell line is seen in
1) Transpharyngeal view
2) Transorbital view
3) Occipitomental view
4) Towne view
Oral Surgery
Answer: 3
The Campbell line is an important anatomical reference line
used in radiology, particularly in the context of the occipitomental
view (also known as the Water's view). This line is drawn from the
outer canthus of the eye to the midpoint of the maxillary sinus and is used to
assess the position of the maxillary sinuses and other related structures in the
skull.
Occipitomental view: This view is commonly used in
maxillofacial imaging to visualize the maxillary sinuses, orbits, and nasal
cavity. The Campbell line helps in evaluating the relationship of these
structures.
Transpharyngeal view: This view is used to visualize the
pharynx
Transorbital view: This view focuses on the orbits and
surrounding structures
Towne view: This view is used to visualize the occipital
bone and the base of the skull

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.
The alkayat and Bramley approach to the TMJ is a modification of the
1. Hemicoronal approach
2. Retroauricular approach
3. Preauricular approach
4. Risdon"s incision
Oral Surgery
Answer: 3
The alkayat and Bramley approach to the TMJ is a modification of the preauricular approach.
After the surgical removal of chronically infected teeth in a controlled diabetic patient, which of the following is of utmost importance
1) Postoperative check of patient for bleeding
2) Revaluation of insulin dosage being taken by the patient
3) Both the above
4) None of the above
Oral Surgery
Answer: 2
Diabetes affects wound healing and immune response. After surgery, stress and altered eating patterns can impact blood glucose levels. Monitoring and adjusting the insulin dosage as necessary is critical to prevent complications such as infection or delayed healing. Postoperative bleeding is important but secondary to glycemic control in diabetics.
Which of the following is complication of an open fracture
1) Malunion
2) Nonunion
3) Infection
4) Crepitation
Oral Surgery
Answer: 3
An open fracture is a fracture that communicates with the outside environment, typically through a wound. This increases the risk of bacterial infection
According to gate control theory of pain, large fiber impulses tend to
1. Bypass the central control process
2. Inhibit the effect of painful stimuli transmitted by small fibers
3. Both the above
4. None of the above
Oral Surgery
Answer: 2
According to gate control theory of pain, large fiber impulses tend to inhibit the effect of painful stimuli transmitted by small fibers.
