Endoscopic management of posterior nasal obstruction

The use of the rigid endoscope has been investigated in the management of 63 cases with posterior nasal obstruction. It was found to be a true advance in rhinology, since it visualizes and localizes the site of the obstruction which is classified into pre-choanal, and post-choanal. Moreover, the nasal endoscope allowed complete and safe removal of most of the obstructing lesions under direct endoscopic vision.
