Localization of the pathological focus in functionally significant and radiosensitive zones sometimes limits the use of radiosurgery as a method of single high-dose irradiation of the tumor. In the case of convexital localization of these tumors with a volume of 5 cm3 to achieve effective single-time treatment without radiation damage to the skin is almost impossible.
The article presents a clinical case in which a new method is applied to improve the safety of treatment while maintaining the effectiveness of treatment by reducing the dose to the scalp in the projection of the tumor taking into account the high prescribed dose for the pathological focus. The inventive method is based on using a biodegradable filler to allow inflation of the skin in the projection of the convexital tumors are located and to plan radiosurgical operation, taking intoconsideration its shifting.
