Correlation between olfactory disorders and morphology of nasal cavity / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To analyze the correlation between olfactory disorders and the morphology of nasal cavity in chronic rhinosinusitis (CRS).@*METHOD@#One hundred and seventy-six patients with chronic rhinosinusitis and/or polyps were included. Olfactory function, the morphology of nasal cavity and nasal sinus, especially the morphology of olfactory cleft, were surveyed by T&T Olfactometer, nasal endoscope and computed tomography (coronal and horizontal position). All patients were divided into 5 groups by different olfaction level. Data was achieved by the scoring endoscopic appearances of Kennedy, and CT staging system of Lund-Mackey and analyzed by SPSS 11.5.@*RESULT@#(1) Among all patients, 61.9% accompanied with hyposmia, 21% with anosmia , the other 17.1% with normal olfaction; (2) There was positive correlation between the scores of staging system of Lund-Mackey and the olfactory function level (P < 0.01) (3) There was positive correlation between the scores of endoscopic appearances of Kennedy and the olfactory function level (P < 0.05).@*CONCLUSION@#(1) Olfactory function were correlated with the severity of CRS; (2) As the determining methods of CRS, staging system of Lund-Mackey can be used to estimate the olfactory function generally and initially; (3) There was not significant difference between the scores of endoscopic appearances of Kennedy and the olfactory function level.
