Abstract

Objective

The aim of this study is to measure the distance from the midline of the upper incisors to the lower pole of the tonsils in paediatric patients of varying ages. This will enable the design of accurately sized tonsil tie simulators.

Methods

Two hundred patients between 1 year and 16 years old were recruited in this prospective observational study. The patient's age and the mean distance from the midline of the upper incisors to the lower pole of the tonsils were plotted into a scatter plot and the line of best fit was calculated.

Results

The equation for the line of best fit was: distance (mm) = 1.9604 × age (digitalised years) + 72.436.

Conclusion

This is the first study to measure the anatomical distance from the upper incisor teeth to the inferior tonsillar pole in a paediatric population. This can be used to accurately size tonsil tie simulators and enhance their fidelity.
