Abstract

Abstract:

BACKGROUND: With the extensive application of cone-beam CT in oral and craniofacial surgery, a clear airway indicator for normal population has important implications for the diagnosis and prevention of airway-related abnormalities.

OBJECTIVE: To determine the cone-beam CT measurements of the upper airway (length, width, cross sectional area and volume) in populations aged 6-19 years from Shandong, so as to provide a reference marker for the diagnosis and treatment of upper airway obstruction in local children and adolescents.

METHODS: Totally 254 healthy children (120 males and 134 females) aged 6-19 years from Shandong were subject to cone-beam CT scan of the upper airway. Mimics10.01 was used to measure the sagittal diameter, transverse diameter, cross-sectional area and volume of nasopharynx, palatopharynx, glossopharyngeal planes, and then the normal value range was confirmed. Independent-sample t-test was used for analysis of gender difference and 95% confidence interval was calculated.

RESULTS AND CONCLUSION: There were gender differences in a part of indicators of the upper airway among 8-9 years, 10-11 years, 16-17 years, 18-19 years groups. These findings indicate that the normal values of radial lines, cross sectional area and volume of the upper airway as well as 95% confidence interval value provide references for the diagnosis of upper airway obstruction and post-treatment evaluation of anatomic form of the upper airway in local children and adolescents.
