title: Modified method of acoustic rhinometry.
abstract: Acoustic rhinometry is a well-known method for evaluating nasal cavity patency using sound waves. The method produces graphical information on cross-sectional areas, the distances between these areas and the nostril and the nasal volume. We used this method to evaluate 40 children aged between 7 and 13 years old with complaints of nasal obstruction. All patients underwent endoscopic examination of the nasal cavity, and only children presenting with hypertrophic inferior nasal turbinates and with no history or clinical evidence of infectious rhinitis were included in the study. Using a modified method we obtained four distinct and constant cross-sectional areas along the nasal cavity and four corresponding distances from these areas to the nostril.
