ABSTRACT
UNLABELLED Nasal septum deviation (SD) and turbinate hypertrophy (TH) increase the resistance to respiratory airflow and may impair nasal patency. OBJECTIVE:
To characterize the nasal geometry of individuals with nasal obstruction secondary to SD and/or TH by means of acoustic rhinometry.METHOD:
This prospective study included 30 adults with complaints of nasal obstruction (NO) and SD + TH (n = 24), SD (n = 5) or TH (n = 1) seen by clinical examination. The cross-sectional areas of the three main dips of the rhinogram (CSA1, CSA2, CSA3), the distance between them and the nostrils (dCSA1, dCSA2, dCSA3), and the volumes of segments 1.0-3.2 cm (V1), 3.3-6.4 cm (V2), and 7.0-12.0 cm (V3) were measured before and after nasal decongestion (DN). For analysis, right and left cross-sectional areas and volumes were added and mean dCSA was calculated.RESULTS:
Mean values (standard deviation) before ND were 0.83 ± 0.23 (CSA1), 1.66 ± 0.52 (CSA2), and 2.36 ± 0.77 (CSA3) cm2; 2.19 ± 0.20 (dCSA1), 4.01 ± 0.33 (dCSA2), and 5.85 ± 0.37 (dCSA3) cm; 2.77 ± 0.51 (V1), 6.52 ± 1.99 (V2), and 26.00 ± 9.62 (V3) cm3; all values were lower than laboratory reference values (p < 0.05). ND led to proportionally greater increases of sectional areas and volumes in the NO group, suggesting an associated functional component. Individual analysis revealed 12 cases with normal results despite nasal obstruction.CONCLUSION:
Most patients with structural nasal obstruction had results suggestive of nasal patency impairment in acoustic rhinometry.
