Oral and maxillofacial anatomy and function are important and complex. They are involved in facial expressions, chewing, language, breathing, and other functions. It is therefore important to choose the optimal treatment plan for oral and maxillofacial tumors. For patients with who cannot tolerate surgery or who refuse surgery or radiotherapy can be treated with cryoablation. Cryoablation can maintain local tissue integrity and organ function and protect facial integrity. It is a repeatable treatment that, if necessary, can be followed by traditional antineoplastic therapies. This study introduces five cases with severe basic diseases who cannot tolerate or have refused surgery or radiotherapy. The patients were diagnosed as having oral and maxillofacial tumors. These patients experienced painful local swelling or breaking of the tumor. All patients received cryoablation combined with other treatments. Local control of the tumors and improved function and quality of life were achieved. In clinical work, for patients with severe basic diseases who cannot tolerate or refuse surgery or radiotherapy, cryoablation has unique advantages, and this approach is expected to become a widely used treatment for oral and maxillofacial tumors.
