The Effect of Modified Olfactory Training on Postoperative Olfactory Dysfunction in Patients With CRS

"Four odorants are used: phenyl ethyl alcohol (PEA): rose, menthol: mint, citronellal: lemon, and eugenol: cloves. Training patients will receive four glass vials. Each contains one odorant (5 mL, soaked in cotton pads to prevent spilling) and is labeled with the name of the odorant.~Budesonide irrigation can effectively target the olfactory cleft area to provide anti-inflammatory effects."

"The modified olfactory training device is based on the nasal bidirectional drug delivery system. The device uses breathing pressure to create positive pressure, significantly increasing the deposition rate of odors in the olfactory cleft area.~Budesonide irrigation can effectively target the olfactory cleft area to provide anti-inflammatory effects."
