摘要

FIELD: medicine.;SUBSTANCE: method involves performing orbitotomy for excising tumor ad maximum and applying inraoperative photodynamic therapy and chemotherapy. Photosensitizing agent is introduced at a dose of 0.1-1.0 mg/kg of body weight 3 days before the operation. The postoperative cavity formed as a result of operation is filled with physiologic saline immediately after removing the tumor and washing-off the operation wound. Cylindrical diffuser light guide is introduced into the wound and laser radiation treatment is carried out at 670 nm wavelength and power density of 120-800 mW/cm². The physiologic saline is removed. The light guide is withdrawn. The wound is sutured. Chemotherapy is applied in postoperative period.;EFFECT: enhanced effectiveness of tumor destruction; reduced risk of post-irradiation complications.;5 dwg
