Dr. Sun Guohong answered that the operation time for parotid gland mixed tumors usually takes 1 to 3 hours. It varies from person to person. Some patients’ tissues are easy to separate, while others are not. In addition, the length of the operation depends on the doctor’s skill. The degree, detail, length of the incision, and size of the tumor are all related. In short, it doesn’t matter whether the operation time is longer or shorter. The key is to remove the tumor together with the superficial lobe of the parotid gland, and even the deep lobe, and at the same time, it must be completely removed. Preserve the facial nerve and minimize the damage to the facial nerve. Only in this way can we effectively avoid tumor recurrence, avoid drooping of the corners of the mouth, avoid complications such as inability to close the eyelids, and achieve the best surgical results. As for the choice of anesthesia, either local anesthesia or general anesthesia is acceptable, with general anesthesia having better analgesic effect.
