    Abstract:
    OBJECTIVE: To investigate the relationship between the subjective sensation of nasal obstruction and the corresponding objective parameters of acoustic rhinometry. METHOD: Three hundred and sixty-five patients with nasal diseases were divided into two groups: one group included 220 cases with nasal obstruction, and the second group of 145 cases without nasal obstruction. Seventy healthy adults were selected as control. Each one were assessed for nasal minimal cross-sectional area (NMCA), volume of nasal cavity (NV), nasal airway resistance (NAR) and distance of the minimal cross section area from the nostril (DCAN) by using acoustic rhinometry, and the subjective test were performed using the VAS scores. The results were statistically analyzed. RESULT: NV, DCAN and NAR had a significant difference between nasal obstruct group and control group (P < 0.05). The VAS score had linear correlation with NMCA, NV, DCAN and NAR, and the correlation coefficient were R(NAR) = 0.7385, R(NV) = -0.853 2, R(NMCA) = -0.745 4 and R(DCAN) = 0.369 7, respectively. CONCLUSION: Since NAR and NV coincide with the subjective perception of patients with nasal obstruction, they can be used as the sensitive parameters to evaluate subjective symptoms of patients.
