Radioisotope dressing therapy (referred to as “dressing therapy”) is a dressing device of a certain shape and size made of radionuclide evenly adsorbed on filter paper (32P). The dressing is applied to the skin of the lesion and the superficial lesion is treated by the ionizing radiation of the beta ray emitted from the dressing. Due to the short range of beta radiation, it has no adverse effect on deep or adjacent tissues. Fixed shaped and sealed dressings are also used (the most commonly used is the 90Sr-90Y dresser). These isotopes emit radioactivity at a distance of 2-3 mm, so they generally have no adverse effect on the tissues below the skin. There is no sensation and no pain during the dressing treatment, except for a slight coolness of the applicator. The dressing can be used for limited neurodermatitis, capillary hemangioma, vascular nevus, scar hyperplasia, chronic eczema, psoriasis, oral mucosa and female vulvar leukoplakia. If a specially made applicator is used, it can also be used for non-specific inflammation of the cornea and conjunctiva, ulcers, pterygium and neovascularization after corneal transplantation. However, the dressing is not suitable for allergic dermatitis, summer eczema and extensive neurodermatitis, eczema and psoriasis.
