Comparison of Therapeutic Effects and Olfactory Function of Oral Glucocorticoid and Intranasal Glucocorticoid on Chronic Rhinosinusitis Patients with Nasal Polyps.
OBJECTIVE: To compare the therapeutic effects and olfactory function of oral glucocorticoid and intranasal glucocorticoid in patients with chronic rhinosinusitis (CRS) with nasal polyps. STUDY
Design: Experimental study. PLACE AND DURATION OF STUDY: Suzhou Hospital of Integrated Traditional Chinese and Western Medicine, from January 2018 to November 2019. METHODOLOGY: One hundred and twenty-two CRS patients with nasal polyps were randomly divided into Group A and Group B with 61 cases in each group. Group A received local application of glucocorticoid (dexamethasone) after nasal endoscopic surgery. Group B received oral glucocorticoid (prednisone) one week before operation and three weeks after operation. Clinical effects of the two groups were compared.
Results: Total effective rate of Group B was higher than that of Group A (p=0. 023), recurrence rate in Group B was lower than that in Group A (p=0.015). Nasal airway resistance and olfactory function scores of Group B were lower than those of Group A at one month, three months and six months after operation (all p <0.001). There was no difference in the incidence of adverse reactions between the two groups (p=0. 649).
Conclusion: Compared with intranasal glucocorticoid, oral glucocorticoid can obviously improve the therapeutic effect and olfactory function of patients, and the postoperative recurrence rate is lower. Key Words: Sinusitis, Nasal polyps, Endoscopic sinus surgery, Glucocorticoid.
