Malignant salivary gland tumors are classified into low, intermediate, and high grades based on their clinical behavior, rate of spread, and structural characteristics. High-grade tumors are generally more aggressive, tend to invade surrounding tissues and spread to neck lymph nodes, and carry a higher risk of distant metastasis.

The primary treatment for malignant salivary gland tumors is surgical removal. During surgery, it is essential to remove the tumor with a wide margin, including healthy tissue free of tumor spread around it. Critical nerves, such as the facial nerve and nerves providing tongue sensation, must be preserved unless they are directly involved by the tumor. When tumor spread to neck lymph nodes is detected, or in tumors with a high risk of metastasis to these nodes even without obvious involvement, adjacent lymph nodes are also surgically removed (neck dissection).

Radiotherapy may rarely be considered as the main treatment option for very small tumors. However, for larger tumors or those with a high risk of recurrence/spread, radiotherapy is applied to the surgical area after surgery to prevent local recurrence.

Pharmacological treatments (chemotherapy) may be preferred in patients unsuitable for surgery due to other health problems or in cases where the tumor has advanced regional spread and/or distant metastasis.
