Gillies approach for reduction of zygomatic fractures is done through
1. Temporal fossa
2. Infra temporal fossa
3. Infra orbital fossa
4. All of the above
Oral Surgery
Answer: 1
The temporal fossa is located on the side of the skull, above the zygomatic arch and lateral to the orbit. The Gillies approach involves an incision in the temporal region to access the zygomatic bone, which is then manipulated to reduce the fracture and restore its normal anatomical position. This approach is commonly used in oral and maxillofacial surgery for the management of complex zygomatic fractures.

1. 4 mg/kg body wt
2. 5 mg/kg body wt
3. 5 mg/kg body wt

The elevator can be used to advantage when
1. The tooth to be extracted is isolated
2. The interdental bone is used as a fulcrum
3. The adjacent tooth is not to be extracted
4. Multiple adjacent teeth are to be extracted
Oral Surgery
Answer: 4
The elevator can be used to advantage in scenarios where multiple adjacent teeth
are to be extracted, as it provides a more precise and controlled method of
elevating the teeth, especially when they are closely spaced or have converging
roots.
The effect of local anaesthesia can be increased by the addition of
1. Adrenaline
2. Isoprenaline
3. Dopamine
4. Felypressin
Oral Surgery
Answer: 1
The effect of local anaesthesia can be increased by the addition of adrenaline.
"Ash forceps" is commonly used for
1. Extraction of lower incisor
2. Extraction of upper canines
3. Holding tissues prior to biopsy
4. Holding vascular areas during surgery
Ash forceps are commonly used for extraction of lower incisor.
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
Double contrast phase contrast arthroscopy is used to study
1. Clicking of TMJ
2. Deviation of TMJ
3. Joint space
4. Disc
Oral Surgery
Answer: 3
Double contrast phase contrast arthroscopy is used to study the joint space.
