The comparation of different oral corticosteroids withdrawal methods for nasal polyp surgery.

Abstract

Objectives: To compare the efficacy and adverse events of different oral corticosteroids (OCSs) withdrawal methods for chronic rhinosinusitis with nasal polyp after endoscopic sinus surgery (ESS).

Methods: This was a randomized prospective study conducted from Oct 2019 to Jan, 2021. 35 patients who underwent ESS were randomly divided into 2 groups. Regular group (n = 18) received 0.4mg/kg/day of methylprednisolone orally for 10 days, tapering group (n = 17) received 0.4mg/kg/day of methylprednisolone orally for 7 days, followed by progressive reduction of 8 mg of methylprednisolone per week for 3 weeks. The visual analogue scale (VAS) score, the Lund-Kennedy endoscopy (LKE) score, and the E score were assessed preoperatively and at half and 1, 2, and 12 months postoperatively. Statistical analyses were performed using SPSS.

Results: There was no statistical difference in the baseline characteristics between the 2 groups. The postoperative VAS scores and LKE scores of patients were significantly improved from those preoperatively (P-values < 0.05). There was no statistical difference in the LKE score, E score, and VAS score between the 2 groups both preoperatively and postoperatively (P-values > 0.05). There was no statistical difference in adverse events between the 2 groups (P-values > 0.05).

Conclusions: The combination of OCSs and ESS can improve the clinical symptoms of patients and the recovery of nasal mucosa. There was no difference between the 2 drug withdrawal methods in efficacy and adverse events. Drug withdrawal gradually is more complicated therefore, in clinical practice, OCSs withdrawal directly would be the better option for patients.
