Abstract:Head and neck lymphoedema (HNL) in head and neck cancer (HNC) patients is generally underrecognised and undertreated, while it could result in cosmetic, functional, and psychosocial problems when the damage is severe or no intervention is undertaken. The most effective way to diagnose and treat lymphoedema following HNC is not yet known due to lack of evidence. One of the greatest challenges is the absence of a universal measurement instrument. Therefore, the goal of this thesis was to find an effective and efficient measurement instrument for monitoring HNL in cancer patients. A systematic review was performed. 3D stereophotogrammetry, tape measurements, and tissue dielectric constant were identified as convenient instruments for measuring HNL in HNC patients. A prospective cohort study was performed to evaluate construct validity, reliability, and responsiveness of 3D stereophotogrammetry for measuring soft tissue changes in the head and neck area. Good measurement properties were demonstrated for quantifying postoperative oedema in patients after bilateral sagittal split osteotomy. Distance map and volumetric parameters demonstrated additional value for localizing and quantifying swelling over time. For clinical applicability of 3D stereophotogrammetry in HNL patients, the measurement protocol should be improved and measurement properties must be evaluated in HNC patients with HNL.
