Endoscopic Sinus Procedure

www.sinuscentro.com.br - Endoscopic sinus surgery in patient with CRS. Note the "maxillary line" or simple the "m" line, which is a nice anatomical landmark for the maxillary sinus natural ostium.
The maxillary sinus natural ostium is hidden behind the uncinate process. However, for a safe and effective maxillary sinus surgery, its natural ostium must be seen to avoid a phenomenom called "recirculation".
There is no anatomical landmark for the maxillary sinus natural ostium and we propose the "m" line, which is a line from the most inferior aspect of the ethmoid bulla to the lateral wall. Wherever the line crosses the uncinate, the maxillary sinus natural ostium will be seen, always angled.
Note the "m" line in this case. More informations: www.sinuscentro.com.br
