Endoscopic-Assisted Antral Washout


 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.

Illumination of Paranasal Sinus

An illumination of right maxillary sinus for confirmation of correct entry and positioning before the balloon andvancement and inflation.  Similar illumination is seen in frontal sinus but least visible in sphenoid sinus.

Powered Instruments: The Microdebrider

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.
