OBJECTIVES: Steroid-eluting stent implantation after endoscopic sinus surgery (ESS) effectively alleviates postoperative symptoms and polyp recurrence in patients with chronic rhinosinusitis with nasal polyps (CRSwNP). However, the efficacy of steroid-eluting stents for the treatment of olfactory dysfunction in CRSwNP and the influencing factors therein have not been studied.
METHODS: Fifty-nine patients with CRSwNP with olfactory dysfunction from Peking University Third Hospital who were hospitalized for ESS were recruited and randomly divided into a stent group (n = 30) and a control group (n = 29), and were assessed for symptom scores, olfactory function, endoscopic findings, and type 2 inflammatory mediators (IL-4, IL-5, IL-13, IL-33, eotaxin-3, periostin) expression.
RESULTS: Postoperative olfactory Visual Analogue Scale (VAS) scores, T&T olfactometer scores, SNOT-22 scores, and Lund-Kennedy (LK) scores were reduced in patients with CRSwNP (P < .01). Postoperative olfactory VAS scores, T&T olfactometer scores, SNOT-22 scores, and LK scores, IL-5, IL-13, and periostin were significantly lower in the stent group than in the control group (P < .05). Correlation analysis was performed and found that the postoperative olfactory VAS scores were strongly correlated with IL-5 and IL-13 (r = .496, P < .001 and r = .289, P = .026), and the postoperative T&T olfactometer scores were strongly correlated with IL-5 and IL-13 (r = .553, P < .001 and r = .398, P = .002).
CONCLUSIONS: Steroid-eluting stent implantation after ESS is an effective treatment for olfactory deficits in patients with CRSwNP and may be related to the stent's more effective reduction of local type 2 inflammatory mediators in the nasal cavity.
