[Causes and revision endoscopic sinus surgery for recurrent sinusitis].

OBJECTIVE: To investigate the causes of revision endoscopic sinus surgery (RESS), and to evaluate the clinical effect and experience of RESS in the patients with recurrent sinusitis. METHODS: Before the revision surgery, 168 patients (225 sides) with recurrent sinusitis were examed by CT scans and nasal endoscopy. All patients were operated by revision endoscopic sinus surgery. RESULTS: Among the 168 patients, 95 cases (121 sides) had incomplete middle turbinate, 51 cases (75 sides) had maxillary sinus ostium stenosis, 85 cases (117 sides) had nasal cavity adhesion, 48 cases (57 sides) had uncinate process residual, 38 cases (65 sides) had ethmoid hyperostosis, and 25 cases had nasal septum deviation. One hundred and six patients (134 sides) were cured, 40 patients (56 sides) were improved, useful 22 patients (35 sides) were ineffective. CONCLUSION: The most common surgical causes of failures in endoscopic sinus surgery are the disease area remnant, nasal cavity adhesion, maxillary sinus ostium stenosis, uncinate process residual, ethmoid hyperostosis, and nasal septum deviation. Revision endoscopic sinus surgery is a useful way to treat recurrent sinusitis. Preoperative CT scan, correct choice of the anatomic marks of orientation and direction function are the key to operation successful.
