Objectives: To clarify changes of transnasal airflow resulting from endoscopic adenoidectomy in children with adenoid
Patients and Methods: In total 50 children of average age 6.4 years having symptoms of nasal obstruction and adenoid
hypertrophy verified by the nasal fiberendoscopy, were submitted to a rhinomanometric assessment, using the active
anterior method before and after the endoscopic adenoidectomy. We assessed the change of the total nasal inspiratory
airflow (Fl. L+R) and total nasal resistance (Res L+R) at a transnasal pressure of 150 Pa associated with the endoscopic
Results: Value of Fl. L+R measured in the study group population of all 50 children was preoperatively 249,92 ml/sec. and
Res L+R value was 0,929 kPa·l–1·sec. Postoperatively the Fl. L+R was 317,04 mL/sec. and Res L+R value was 0,612 kPa·l
–1·sec. We have noticed statistically significant increase of Fl. L+R (p = 0,015) and the decrease of Res L+R on the border
of statistical significance (p = 0,054).
Conclusions: Endoscopic adenoidectomy significantly increased Fl. L+R in children with nasal obstruction due to adenoid
hypertrophy. Accordingly, after the endoscopic adenoidectomy might be expected increase of transnasal airflow
and reduction of nasal obstruction symptoms.
