Abstract

BACKGROUND AND OBJECTIVES: Endoscopic sinus surgery has recently become a popular and effective treatment method for chronic paranasal sinusitis. Although several papers have been written about the results of ESS, little has appeared about its longterm results. The purpose of this study is therefore to add to the understanding long-terms results of EES by presenting our experience. MATERIAL AND METHODS: We report our experience on 410 patients who underwent endoscopic sinus surgery for chronic paranasal sinusitis from January 1993 to August 1995 and a long term follow-up study from 12 to 36 months. We evaluated their preoperative symptoms, previous nasal surgery history, anatomical variations on the preoperative OMU-CT, pattern of inflammatory sinonasal disease, as well as their postoperative improvement of the symptoms using questionnaires and the endoscopic sinonasal findings.
RESULTS
Nasal obstruction was the most improved symptom. Patients without any history of nasal surgery had relatively good results compared to those with previous operation history. Patients with an OMU anatomical variation also had relatively good results compared to those with no OMU variation. Among the different patterns of chronic paranasal sinusitis based on the Babbel classification, the sinonasal polyposis pattern (IV) showed most inferior postoperative improvement of the symptoms. Nevertheless, the overall postoperative improvement of chronic paranasal sinusitis indicates that the endoscopic sinonasal surgery was effective.
CONCLUSION
On the whole, 371 (91%) of the 410 patients benefited from this procedure, indicating that endoscopic sinus surgery provides an efficient method for treating chronic sinusitis and that sinonasal polyposis can be managed with a high level of success.
