The incidence of complications after canine fossa
puncture performed during endoscopic sinus surgery.
The lesion was subsequently removed with powered instrumentation via an inferior meatal approach, with observation through a telescope passed via the canine fossa
Telescopic maxillary siloscopy via the canine fossa
is an excellent way to study the natural ostium of the maxillary sinus.
Additionally, anterior wall bowing, a widening of the pterygopalatine fossa and infratemporal fossa fat plane, an elevation of the canine fossa
, or a relatively lateral position of the infraorbital canal might be seen.
If symptoms and findings persist, anterior rhinoscopy via a canine fossa
or a mini-Caldwell-Luc approach should be performed and pathology should be removed.
