All of the following statements of nasal fractures are true except
1) Even if minor, they may be followed by bilateral ecchymosis and facial oedema
2) They may need to be reduced for a few weeks
3) They need not be complicated by traumatic telecanthus
4) They may lead to the telescoping of the nasal complex into the frontal sinus
Oral Surgery
Answer: 2
Nasal fractures, even minor ones, can lead to bruising (ecchymosis) and
swelling (edema) around the nose and face due to the vascularity of the area.
Most nasal fractures, especially minor ones, do not require reduction
(surgical realignment) unless there is significant displacement or functional
impairment. Typically, if reduction is necessary, it is done shortly after the
injury, not for a few weeks.
Traumatic telecanthus (increased distance between the inner canthi of the
eyes) can occur with severe nasal injuries, but it is not a necessary
complication of all nasal fractures.
Severe nasal fractures can lead to complications such as the telescoping of
the nasal complex, which may involve displacement into adjacent structures,
including the frontal sinus.
Hypoglycaemia may occur in a patient taking insulin and undergoing extraction when
1. Extraction is done on empty stomach
2. Patient had an infection
3. Patient had no exercise in the morning
4. None of the above
Oral Surgery
Answer: 1
Hypoglycaemia may occur in a patient taking insulin and undergoing extraction
when the procedure is done on an empty stomach. This is because insulin lowers
blood sugar levels, and without food to balance the insulin's effect, the
patient could experience a dangerous drop in blood glucose. It is important to
ensure that the patient eats before the surgery and that glucose levels are
monitored.

Mental foramen opening is directed in
1. Forward and medial direction
2. Backward and medial direction
3. Forward and lateral direction
4. Backward and lateral direction
Oral Surgery
Answer: 4
The mental foramen is found on the buccal aspect of the mandible, typically
between the first and second premolars or the second premolar and the first
molar. The opening of the mental foramen is directed backward and lateral,
allowing the mental nerve to exit and innervate the lower lip and chin.
