Clinical Analysis of Modified Extended Endoscopic Sinus Surgery for Chronic Rhinosinusitis with Nasal Polyps and...

Extended endoscopic sinus surgery (EESS) can reduce the recurrence rate of chronic rhinosinusitis (CRS). The purpose of this study was to investigate the effect of the application of modified "protective middle turbinate-EESS" (mEESS) on patients with CRS with nasal polyps (CRSwNP) and allergic rhinitis (AR). Forty-three patients with CRSwNP and AR were classified into 2 groups, the mEESS group (n=23) and the functional endoscopic sinus surgery (FESS) group (n=20), and were followed up for 6 months and 1 year after surgery. The disease severity was assessed by the Lund-Mackay score, the Lund-Kennedy score, and the visual analog scale (VAS) score. The patency rate of the frontal sinus was evaluated by endoscopy. Patient satisfaction was also followed up. No preoperative differences or postoperative complications were found between the 2 groups. The VAS score and Lund-Kennedy score of the 2 groups were lower at 6 months and 1 year after surgery. The olfactory function of the mEESS group was significantly better than that of the FESS group at 6 months post-operative. The patency rate of the frontal sinus orifice in the mEESS group was significantly higher than that in the FESS group at 6 months and 1 year post-operative. Patient satisfaction in the mEESS group was relatively higher than that in the FESS group. mEESS improves frontal sinus drainage, olfactory sense, and patient satisfaction in the short term.
