Oral Surgery
The Gillies approach is a surgical technique used in facial reconstruction, particularly for the repair of facial defects. The superficial temporal artery is of significant anatomical importance during this procedure, as it supplies blood to the scalp and face. Surgeons must be cautious to avoid damaging this artery during the approach.

Oral SurgeryRapid onset of action seen by local anaesthesia in small nerve endings is due to the high ratio of surface area to the volume of small nerve fibres.

Oral SurgeryTo give a field block, the LA should be deposited near a large branch of peripheral nerve.

Oral SurgeryWhile the buccal nerve block is used to anesthetize the buccal mucosa and buccal
gingival tissues of the maxillary molars, the actual technique does not
typically produce any specific subjective symptoms in the patient other than the
sensation of the needle. The patient may feel numbness if the anesthetic
solution is inadvertently placed in the oral mucosa or if the block is done
improperly.

Oral SurgeryThe 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

Oral SurgeryThe inferior alveolar nerve exits the mandibular foramen and runs in the
mandibular canal before it branches off to supply the teeth, including the
second premolar. To anesthetize the nerve at this point, the injection site is
commonly located between the first and second premolars, inferior to the root
apices, where the nerve is relatively superficial and accessible.

Oral SurgeryNasal 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.
