This trial investigates a new approach using a mobile three-dimensional (3D) scanning application for volumetric measurement of the head and neck region in patients with head and neck lymphedema. Lymphedema is the buildup of extra lymph fluid in tissues that causes swelling. Accurate volumetric measurements of swelling are crucial to the diagnosis of lymphedema and to monitoring response to therapy and disease progression over time. A mobile 3D surface scanning application may help doctors measure and analyze swelling in patients with head and neck lymphedema.
