Brief 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.

Outcome Measures

Primary Outcomes (1)

  • Change from baseline at months 1, 3, 6 and 12 in 22-item sino-nasaloutcome test (SNOT-22) scores after surgical intervention

    The SNOT-22 is a validated questionnaire that was used to assess the impact of chronic rhinosinusitis on health-related quality of life (HRQoL). It is a 22 item questionnaire with each item assigned a score ranging from 0 (no problem) to 5 (problem as bad as it can be). The total score may range from 0 (no disease) to 110 (worst disease), lower scores representing better health related quality of life.

    1month, 3month, 6month, 12month

Secondary Outcomes (6)

  • Revision surgery rate

    12month

  • Symptom duration

    1month, 3month, 6month, 12month

  • Postoperative medication

    1month, 3month, 6month, 12month

  • Recurrence time

    1month, 3month, 6month, 12month

  • Change from baseline at months 1, 3, 6 and 12 in visual analogue scale (VAS) after surgical intervention

    1month, 3month, 6month, 12month

  • +1 more secondary outcomes

Other Outcomes (1)

  • Changes from baseline at months 1, 3, 6 and 12 in molecular indices of nasal lavage fluid

    1month, 3month, 6month, 12month

Study Arms (2)

Modified radical endoscopic sinus surgery(MRESS)

EXPERIMENTAL

The experimental group intends to adopt a modified radical endoscopic sinus surger to remove the mucosa including ethmoid sinus and maxillary sinus, as well as a completly middle turbinate resection to achieve a radical cure of ethmoid sinus. Antrostomies of frontal and sphenoid sinuses were then performed with meticulous operation and preserve the mucosa intactly.

Procedure: Modified radical endoscopic sinus surgery

Functional endoscopic sinus surgery (FESS)

EXPERIMENTAL

FESS was performed by Messerklinger technique, operation procedures including full maxillary antrostomy, ethmoidectomy, sphenoidotomy and frontal sinusotomy, but with the middle turbinate preservation.

Procedure: functional endoscopic sinus surgery

Interventions

Modified radical endoscopic sinus surgery was performed to remove the mucosa including ethmoid sinus and maxillary sinus, as well as a completly middle turbinate.
