Abstract:ObjectiveTo explore the clinical efficacy of revision endoscopic sinus surgery for recurrent chronic rhinosinusitis (CRS).MethodsClinical data of 68 patients with recurrent CRS hospitalized in our department from Jan 2011 to Jan 2016 were analyzed retrospectively. All the patients received revision endoscopic sinus surgery and comprehensive management during perioperative period and were followed up more than 12 months.ResultsAt one year after surgery, the effective rate for 41 recurrent CRS cases without nasal polyps was 90.2%, while that for 27 cases with nasal polyps was 81%. No serious orbital and intracranial complications occurred.ConclusionWith significant curative effect, revision endoscopic sinus surgery is very important for the treatment of recurrent CRS.
