Background:
Head and neck lymphedema is a common complication of head and neck cancer treatment. It poses aesthetic concerns and functional (speech, swallowing, respiration, and movement) impairment. Detection and progression monitoring of lymphedema is largely based on precise and reproducible volume measurements. No current head and neck external volume measurement tool exists. We present a non-invasive, rapid, accurate and cost-effective 3-D surface scan application to measure head and neck volumes.
Methodology:
Our single-center, cross-sectional study, conducted under Institutional Review Board standards, involved twenty-five healthy subjects. Data collection occurred at two timepoints using software developed by KnockOut technologies on a Samsung tablet.
Results:
Twenty-five subjects (nineteen women and six men) were included in our study. Time elapsed between first scan and second scan ranged between fourteen and twenty-seven days, with average elapsed time being 16.4 days. Volumetric measurements ranged between 745.99 cm3 – 1199.68 cm3 for scan one and 727.23 cm3 – 1201.71 cm3 for scan two, with no statistical change in BMI. Absolute differences were between 0.23% - 8.91%, with an average of 4.02%. Intra-rater reliability was excellent with ICC of 0.959.
Discussion and Conclusion:
Our research introduces a novel, non-invasive method to objectively measure head and neck volume changes. Enabling accurate tracking of facial edema and allowing earlier detection of subclinical lymphedema. Earlier intervention based on precise measurements could improve patient outcomes.
