Surgery for mixed tumors usually takes about 1 to 3 hours to complete. Mixed tumors are most common in salivary gland tumors, such as parotid mixed tumors, and surgery usually takes about 1-~3 hours. In the case of benign mixed tumors, the tumor tissue is relatively well separated and the surgical operation is relatively simple and can be completed in about 1~2 hours. If it is a malignant mixed tumor, the tumor tissue needs to be completely removed in order to control the progression of the disease, and the operation may take about 2~3 hours. The length of time for a mixed tumor surgery varies from person to person and there is no standardized time frame. Before deciding to have a mixed tumor surgery, it is recommended to go to a regular specialized hospital and choose a surgeon with high technical level to do the surgery, which can reduce the risk of the surgery, ensure the success rate of the surgery, and shorten the time of the surgery. After having mixed tumor surgery, you should also go to the hospital for regular checkups to clarify the healing of the wound after surgery and whether there is any infection.
