Summary

Functional endoscopic sinus surgery (FESS) is the pimary surgical treatment of CRS, characterized with the preservation of nasal structure and function.But the control of disease by surgery has been unsatisfactory. Recent studies have shown that patients with recurrent CRSwNP (usually with severe eosinophilic inflammation), more radical surgery may be more effective. The purpose of this prospective and randomized study is to determine the effect of endoscopic sinus surgery for extensive mucosal removal in patients with eosinophilic chronic rhinosinusitus with nasal polyps.

Description

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a multifactorial inflammatory disorder that causes various symptoms including nasal obstruction, rhinorrhea, olfactory dysfunction, facial pain, and headache. Patients with significant eosinophilic inflammation usually accompanied with a higher recurrence rate and more severe clinical symptoms. Endoscopic sinus surgery (ESS) is recommended to patients who do not response well to conservative treatments. A retrospective study showed that postoperative polyp recurrence rate of patients with severe eosinophilic inflammation was significantly reduced by rebooting sinus mucosa. In this study, the experimental group intends to adopt a modified radical surger to remove the mucosa including ethmoid sinus and maxillary sinus, as well as a completly middle turbinate resection to achieve a extensive treatment of ethmoid sinus. Antrostomies of frontal and sphenoid sinuses were then performed with meticulous operation and preserve the mucosa intactly.
