Several years ago, Corten got introduced to Extended Reality, a term used as an umbrella for Virtual Reality (VR) and Augmented Reality (AR). The project Seeing is Believing is granted by the Top Sector Health~Holland Life Science & Health, which stimulates public-private partnerships. In the future, other patient groups in which preoperative expectation management and postoperative facial appearance or body image play an important role can also benefit from Corten’s project. While the application probably will not be perfect in three years, it will be much better than the current material used for preoperative counselling.’ We, on the other hand, must deal with faces that are affected by skin cancer and deviate from ‘standard’ faces. ‘Snapchat’s algorithms are based on hundreds of thousands of photos of normal faces. Facial deformitiesĬorten realizes the big challenge is the development of software. Image of a ‘forehead flap’ as it currently appears in the patient brochure. If you can use this XR technique to show their facial appearance after the surgery, the patient knows what to expect.’ After the first stage a skin pedicle is temporarily present, connecting the forehead to the nose. A technique to reconstruct the nose is to transpose a piece of skin from the forehead to the nose. Personalized information is also necessary in the process of shared decision-making and in choosing what type of reconstruction suits the patient best. With ‘Seeing is believing’, we want to achieve this.’ Our patients need personalized, more lifelike educational material. A woman doesn’t recognize herself in that. Sometimes patients are provided with examples, for example, a picture of a male patient with a moustache. ‘At present, very little visual material is available to explain to patients the different stages of the procedure and what the expected result might look like. Often multiple surgeries are needed to achieve an optimal result.’ Moustache ‘This is important because the face plays a key role in social interaction. ‘Reconstructive plastic surgery aims to restore form and function of the face,’ says Corten. Usually, equally invasive surgery is needed to reconstruct the face after removing the tumour. Removing the tumour is often very invasive for patients with facial skin cancer. In theory, this should also allow us to show what your face looks like after surgical reconstruction.’ Or you can look 30 years younger or older. You’ll suddenly be wearing crazy glasses or have stars in your eyes. She is receiving 425,000 euros in funding for her project, titled Seeing is Believing.Ĭorten was inspired by the technology behind apps like Snapchat and Face Swap: ‘Its algorithms have been developed with millions of existing photos of ‘normal’ faces, allowing you to apply a filter to your own face. Reconstructive plastic surgeon Eveline Corten is developing an Extended Reality application that allows patients with facial skin cancer to look at lifelike images of the expected outcomes of their facial reconstruction.
