Postsurgical facial oedema is difficult to quantify accurately as it is three dimensional. Over the years, various measurement techniques have been tried to measure oedema objectively. These include direct linear measurement using tape or flexible rulers across fixed soft tissue landmarks, standardized stereophotographic measurements, computerized tomography (CT), magnetic resonance imaging (MRI), ultrasonography (US) and three - dimensional (3D) laser scanning. Recently, three dimensional image reconstructions using a reversed engineering technique has been developed and is used in the manufacturing industry. This technology could be applied in a clinical setting for monitoring soft tissue changes.
