Abstract

Objective: To determine a normative value for the nasopharyngeal depth from the anterior nasal spine (ND-ANS) among normal adult Filipinos using Computed Tomography scans.

Methods:
Design: Cross-sectional study
Setting: Tertiary National University Hospital
Participants: Of 516 adult patients that underwent facial, neck and temporal bone CT scans in our hospital between January 1 to June 30, 2019, 100 cases were randomized to be included in the study and 91 CT scans were analyzed.

Results: The mean nasopharyngeal depth from the anterior nasal spine among Filipino adults is 7.17 ± 0.42. There was a significant difference between sexes with a mean measurement of 7.23 cm ± 0.44 in males and 7.09 ± 0.37 cm in females. There was no statistically significant difference in mean nasopharyngeal depth across age groups.

Conclusion: A statistically significant difference was observed between sexes in our study sample. Our study provides initial normative values of nasopharyngeal depth among adult Filipinos, and additional studies may use this as a basis for further research.
