Qi W, Feng L, Yang F, et al. - Researchers conducted the study for analyzing the impacts of age on the olfactory function recovery of chronic rhinosinusitis patients after endoscopic sinus surgery and related risk factors. A total of 176 chronic rhinosinusitis (CRS) patients were enrolled between February 2017 and October 2019 and were divided into four age groups: child, youth, middle-aged, and elderly. Their baseline data, T&T olfactory test score, visual analogue scale olfactory score, sinus computed tomography Lund-Mackay score, and Lund-Kennedy score have been compared. The improvement in the olfactory function of CRS patients following endoscopic sinus surgery diminishes with age. Risk factors for impaired postoperative olfactory function include age, preoperative Lund-Mackay and Lund-Kennedy scores, nasal polyp complications, allergic rhinitis history, sinus surgery history, and postoperative complications. Treatment under the supervision of a doctor is an important factor in achieving good results.
