Comparative study of nasal stents and nasal packing in patients undergoing septoplasty

To investigate the safety and effectiveness of nasal stent in clinical application by comparing and observing the clinical effect and comfort of nasal stent and merocel sponge applied in nasal septoplasty. Methods: patients with nasal septal deviation were selected and randomly divided into nasal stent group (experimental group) and merocel sponge group (control group) according to the packing method. The hemostasis effect, comfort and complications of the two groups were compared during the packing period.
