In rhinomanometry, total nasal resistance at 150 Pa decreased from a mean of 0, 62±0, 17 Pa / cm3 / s preoperatively to a mean of 0, 20±0, 06 Pa / cm3 / s 2 months postoperatively (p<0, 001); the nasal airflow mean increased from 254, 44±65, 44 cm3 / s preoperatively to 825, 39±224, 15 cm3 / s 2 months postoperatively (p<0, 001).
