Abstract

Twenty-eight pediatric patients between the ages of 2 and 13 years underwent intraoperative measurement of the nasal choanae using an instrument custom designed for this purpose by the Pilling Surgical Instrument Company. Additional data points recorded included age, surgical procedure, and the presence or absence of nasal obstructive symptoms which was determined by carefully questioning parents or guardians. Results were analyzed using linear regression, analysis of variance, and logistic regression. Data supported the following conclusions: (1) a linear relationship exists between age and average choanal size with the choanae enlarging at a rate of 0.208 ± 0.09 mm per year (P < 0.03, r2 = 0.16); (2) there is no significant difference between the average choanal size in children with and without nasal obstructive symptoms; (3) the size of the posterior choanal air space cannot be used to accurately predict the presence or absence of nasal obstructive symptoms in children between the ages of 2 and 13 years.
