Abstract:Objective To explore the impact of cefaclor combined with corticosteroid infiltration on the recovery of nasal mucosa and prognosis in patients with chronic rhinosinusitis post-surgery.Methods Ninety-six patients with chronic rhinosinusitis treated at The Second People's Hospital of Lianyungang from January 2021 to December 2022 were selected and randomly divided into a control group (n = 48, receiving conventional post-sinus surgery care) and an observation group (n = 48, receiving additional cefaclor combined with corticosteroid infiltration on top of the conventional care). The outcomes compared between the two groups included Visual Analogue Scale (VAS) scores for rhinorrhea, nasal congestion, nasal itch, and sneezing; as well as mucociliary function, mucosal recovery, inflammation levels, quality of life, complications, and prognosis.Results At 1 month post-treatment, the observation group exhibited significantly lower VAS scores for rhinorrhea, nasal obstruction, nasal itching, and sneezing compared to the control group (P < 0.05). The differences in pre- and post-treatment VAS score reductions were also greater in the observation group. Nasal mucociliary clearance improved in the observation group, with shorter mucociliary transport time (MTT) and higher mucociliary transport rate (MTR) (P < 0.05). The Lund-Mackay and Lund-Kennedy scores at 3 months were significantly lower in the observation group (P < 0.05), with greater score reductions than the control group. Inflammatory markers (TNF-α, IFN-γ, IL-5) were significantly reduced in the observation group at 1 month (P < 0.05), with more pronounced decreases than the control group. The Sino-Nasal Outcome Test-22 (SNOT-22) scores at 3 months were significantly lower in the observation group across all domains (P < 0.05). No significant differences were observed in adverse events or recurrence rates between the two groups (P > 0.05).Conclusion The treatment involving cefaclor combined with corticosteroid infiltration effectively improved mucociliary function, mucosal function, and mucosal recovery in patients post-chronic rhinosinusitis surgery, reduced inflammation levels, and maintained good safety, without significantly impacting quality of life.
