Endonasal sinusectomy developed and performed in our department for a long time is a useful method for treating chronic sinusitis.
The key points of this surgical technique under local anesthesia are removal of pathologic mucosa of the anterior and posterior ethmoid sinuses by an endonasal approach, opening of the cellulae and, in addition, establishment of sufficient communication between the ethmoid sinus and the maxillary, frontal sinus. Even if pathologic mucosa is present in the maxillary sinus, we leave it intact and attempt to heal it indirectly by achieving good drainage and ventilation. This surgical technique often, includes correction of septal deviation and conchotomy.
Recently, by using rigid endoscope and a VIDEO system (CCD-camera, TV monitor, etc), surgical complications have been prevented, because of achieving a wide and clear visual field, decreasing the dead angles and give a close view of the site of manipulation of the paranasal sinuses which have a delicate and complicated structure.
Post-operative treatment includes irrigation of maxillary sinus and this is necessary to make a good evaluation. I discuss these surgical techniques, approaches, post-operative findings and evaluations, etc.
