In the treatment of benign bone tumors, the tumor-affected area is first thoroughly imaged using plain radiography, magnetic resonance (MR), and computed tomography (CT). Subsequently, it is evaluated in a multidisciplinary council with the participation of radiology and pathology specialists. If there is doubt in the diagnosis, a biopsy is taken beforehand to establish a definitive diagnosis of the bone tumor. During the surgical stage, the extent of the tumor within the bone is determined, and a wide window is created to access the entire tumor tissue. Through this window, all tumorous tissue is carefully removed and cleaned down to the healthy bone margins using high-speed motors. However, since residual tumor cells at a cellular level may carry a risk of recurrence, adjuvant agents such as cautery, phenol, alcohol, or liquid nitrogen may be used to prevent this. Liquid nitrogen is sprayed into the bone cavity under pressure in special containers, targeting all possible residual tumor cells. During this procedure, liquid nitrogen reaches approximately -190°C, causing the tumor cells to freeze. Subsequently, the environment is raised to approximately +20°C with physiological saline, allowing the cells to thaw. This freeze-thaw cycle causes the tumor cells to rupture and die. This cycle is repeated 3 to 5 times to effectively destroy all tumor cells.
