A Clinical Analysis of Revision Endoscopic Sinus Surgery: Single-Center 10-Year Experience

ABSTRACT

BACKGROUND AND OBJECTIVES: Endoscopic sinus surgery (ESS) has become a popular procedure for treating chronic sinusitis. Despite recent developments in medical and surgical techniques, primary ESS can still fail. Although revision ESS is one solution to the problem of recurrent sinusitis, revision surgery is stressful for patients and otolaryngologists. Therefore, we examined the causes of ESS failure and sought to find ways to prevent the failure of primary ESS. MATERIALS AND METHODS: All patients who underwent revision ESS in our department between April 2003 and March 2012 were studied retrospectively. RESULTS: During this period, revision ESS was performed 40 times to treat chronic sinusitis. We analyzed the preoperative computed tomographic (CT) findings of primary and revision ESS cases using the Lund-Mackay and Kennedy CT staging scores to compare disease severity. In our cases, the failure of ESS was not affected by the extent of disease, asthma, or allergy. Polyposis was the only useful predictor of revision ESS. CONCLUSION: Polyposis is an important predictor of revision ESS. We recommend that patients be followed frequently and carefully, especially those with polyps.
