Analysis Of Olfactory Rehabilitation After Endoscopic Sinus Surgery In Patients With Chronic Sinusitis And Nasal Polyps

Objectives:To evaluate the influence of endoscopic sinus surgery on olfactory disorder caused by chronic sinusitis and nasal polyps, by testing the olfactory function of seventy-four patients before and after endoscopic sinus surgery,and then evaluate the outcomes of olfactory dysfunction after endoscopic sinus surgery in patients with choinc rhinosinusitis and the related factors. Methods:The olfactory function of the seventy-four patients with chronic sinusitis and nasal polyps was tested through the T&T olfactory testing method in pre-operation and four weeks,twelve wees,twenty-four weeks post-operation. According to whether the associated with allergic rhinitis were divided into two groups.Data was achieved by the scoring endoscopic appearances of Kennedy, and CT staging system of Lund-Mackey.Parallel processing standard endoscopic operation and processing specification during peri operation period.Analysis the relationship between the degree of olfactory rehabilitation with allergic rhinitisand chronic sinusitis lesions;Results:1.Compared with the level of olfactory function, significant improvement was found at first month;however, the level of4weeks postoperation olfactory function was significant statistically differences with12weeks and24weeks;2.Lund-Mackey sinus CT score is related to the degree of postoperative nasal olfactory rehabilitation(P<0.05),the higher preoperative score,the worse postoperative sense of smell will be;3.The scores of endoscopic appearances of Kennedy is related to the degree of postoperative nasal olfactory rehabilitation (P<0.05),the higher the preoperative scores, the worse postoperative sense of smell will be;.4.Allergic rhinitis is the influence factors of chronic rhinosinusitis with olfactory dysfunction olfactory rehabilitation, the olfactory rehabilitation of patients with allergic rhinitis are worse than the patients with no allergic rhinitis.5. Course of disease is the influence factors of chronic rhinosinusitis with olfactory dysfunction olfactory rehabilitation.Longer the course of disease,worse the olfactory rehabilitation.6.Eosinophil count was relate to chronic rhinosinusitis with olfactory dysfunction olfactory rehabilitation.Higher Eosinophil count, worse the olfactory rehabilitation.Conclusion:ESS plays a positive role in the improvement of olfactory impairment in patients with CRS. It is important to protect the olfactory mucous on a basis of surgical removal of sinonasal inflammatory. The standard intraoperative procedure, treatment on allergic rhinitis and regular follow-up after operation is also very important.
