Abstract
The past two decades there has been increased use of the endoscope
which allows access to the maxillary sinus pathology through the nose
with the use of angled‐lens endoscopes. This advance in the endoscope
coupled with improvement of radiological modalities helps in
understanding the radiological and the endoscopic anatomy of the PPF
and identification of several landmarks to guid the approach to this area.
