What Is a Parotid Adenoma?
Mixed parotid tumors are more common in middle age. Generally there are no obvious conscious symptoms (no pain, itching), slow growth, and the course of the disease can be years or even decades, which is why patients often cannot pay attention to it. Although the parotid mixed tumor is benign, the tumor can undergo malignant transformation, the rate of malignant transformation is about 3% -5%, the longer the course of disease, the greater the chance of malignant transformation, the malignant rate of 9.5% after 15 years. If one of the following conditions occurs in a tumor, the possibility of malignancy should be considered. The tumor grows rapidly and rapidly, the mobility is reduced or even fixed, pain or ipsilateral paralysis occurs.
Parotid tumor
- Mixed parotid tumors are more common in middle age. Generally there are no obvious conscious symptoms (no pain, itching), slow growth, and the course of the disease can be years or even decades, which is why patients often cannot pay attention to it.
Parotid tumor principle
- The treatment of mixed parotid tumors is based on the principle of complete surgical resection.
- Biopsy is generally not recommended before surgery.
- Because: 1. The tumor capsule is incomplete, prone to tumor implantation during biopsy, 2. Scar tissue is formed after biopsy, which increases the possibility of facial nerve injury during surgery.
Prognosis of parotid tumor
- Early parotid tumors undergo timely and standardized surgery to prevent malignancy, and most patients have no problems after surgery. Biopsy should not be performed before surgery. It is contraindicated for excision of capsular peeling. The tumor must be resected together with the capsule and normal parotid tissue around the tumor, otherwise it is easy to relapse; avoid injury to the facial nerve during surgery. If malignant changes have occurred, radical resection of the parotid gland should be performed, including all facial nerve branches.
