OBJECTIVE: Investigating the acoustic rhinometry parameter values from the patients with deviation of nasal septum. METHOD: Testing 60 cases with deviation of nasal septum by means of Eccovision acoustic rhinometry, recording and statistics analysing nasal minimal cross sectional area (NMCA), nasal cavity value (NCV), distance of minimal cross section area from the nostril (DCAN) and nasal resistance (NR). RESULT: NMCA: (0.37 +/- 0.14)cm2; NCV: (12.30 +/- 2.32)cm3; DCAN: (2.10 +/- 0.15)cm; NR: (0.348 +/- 0.115)kPa x L(-1) x min(-1)]. It is showed by statistics analysis that the values of NMCA and NVC have inverse ratio, and have no correlation with DCNA. CONCLUSION: Acoustic rhinometry can be used as an objective marker to assess nasal ventilation function. It also can definite exactly the place of NMCA and offer reference for clinic surgery.
