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
