Coakley trocar used in this procedure. Above - the cannula, below - the sharp end of the device use to prick and make the opening of the medial wall of the antrum.
Attached cannula sleeved into the trocar. The trocar will be removed and the sleeve left in place for irrigation once antral cavity placement of the tip confirmed.

An example of microdebrider by Medtronic
This device is has becomes widely-used during endoscopic nasal surgery and very useful in removing mass lesions including polyps. Specimen can be collected by siphoning the debrided materials into a collector bottle attached to the suction tube. It is an alternative biopsy method to cold instrument usage.

in "close" [left figure] and "open" position [right figure].
Biopsy was taken prior to polyps removal.
Video showing biopsy of nasal polyps. Prior local infiltration
with marcain/adrenaline was given. Adequate tissue and deeper biopsy
need to be taken especially in suspected malignancy and inverted papilloma.
Video showing polypectomy by using microdebrider. This device sucks and cut the polyps at the same time whenever the foot paddle pressed. The direction of the cutting blade must be seen to ensure safety. The speed can be varied depending on how much pressure exerted on the foot paddle.
