Endoscopic sinus surgery (ESS) continues to gain popularity among otolaryngologists. Of 102 patients who underwent endoscopic sinus surgery, 37 patients (36%) required a revision ESS as they still had nasal blockage, facial pain and postnasal drip. All patients underwent corona' and axial CT imaging of the paranasal sinuses before revision surgery. In all cases, data on CT findings, endoscopic examination findings and intraoperative findings were evaluated. The two most common causes of failure were residual ethmoid air cells (97%) and adhesions (95%). These were followed by maxillary sinus ostium stenosis (43%), septa! deviation (41%), frontal sinus ostium stenoses (38%) and conchal hypertrophy (35%). Our purpose was to evaluate those surgical causes of failure in an attempt to improve on our surgical technique and reduce these causes of failure.
