Analyses of the olfactory disorder patients' nasal airway resistance before and after endoscopic sinus surgery / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To explore the changes of nasal airway resistance (NAR) and olfactory recovery in patients with olfactory disorder before and after endoscopic sinus surgery.@*METHOD@#Olfactory functions and NAR in 105 patients with olfactory disorder diagnosed as chronic rhino-sinusitis and/or nasal polyps were measured with five taste test olfactory liquid and anterior rhinomanometry. The patients were grouped according to their olfactory disturbance degree before the surgery and recovery of olfaction after the surgery.@*RESULT@#Before the surgery, the degree of olfactory disorder were accompanied with varied clinic classifications. Six months after the surgery, the patients whose conditions were less serious before surgery recovered better. Before and after the surgery, significant difference of the nasal airway resistance was found between the three-groups whose olfactory disorder degree were different. After the surgery, no difference was found of the nasal airway resistance between the three-groups whose olfactory disorder degree were different before the surgery and the recovery of olfaction degree were different after the surgery.@*CONCLUSION@#Endoscopic sinus surgery can decrease the nasal airway resistance of patients with olfactory disorder. We can evaluate the efficacy of endoscopic sinus surgery more objectively combined with nasal airway resistance analysis.
