Tongue cancer is the most common oral cancer, more men than women. Most of the tongue cancers are squamous cell carcinoma, especially in the 2/3 front part of the tongue. Adenocarcinoma is rare, mostly located in the base of the tongue. Lymphatic epithelial cancer and undifferentiated carcinoma can sometimes occur in the base of the tongue. Tongue cancer occurs mostly at the edge of the tongue, followed by the tip of the tongue, the back of the tongue and the base of the tongue. It is often ulcerated or infiltrated. Generally, the degree of malignancy is high, the growth is fast, the infiltration is strong, and the tongue muscle is often spread, resulting in limited movement of the tongue, which makes it difficult to speak, eat and swallow. Tongue cancer can invade the lingual arch and tonsil in the posterior, and the advanced tongue cancer can spread to the bottom of the mouth and the jaw bone, so that the whole tongue is fixed. Treating diseases: tongue cancer Indication Benign tumors of the tongue and superficial mucosal carcinoma that has not invaded the margin of the muscle layer can be used for partial resection; 2/3 of the tongue in front of the tongue has invaded the tongue muscle, but it is still limited, and can be used as a half tongue (even Full tongue) resection. Because tongue cancer develops rapidly and metastasizes early, more radical cervical lymph node resection is performed at the same time, or postoperative radiotherapy is used. Contraindications Most of them use lingual nerve block anesthesia, and a few who need extensive tongue resection can be performed under general anesthesia. Preoperative preparation 1. If a malignant tumor is present, it is necessary to examine in detail whether there is local lymph node and long-distance metastasis before surgery. 2. Oral cleaning treatment. Surgical procedure 1. Resection of the tumor: Intubation of the tracheal intubation, the pharynx is filled with wet saline gauze. A traction line is sewed on both sides of the tongue, and the surgical field is revealed by an opener and an oral hook. A slit through the entire thickness of the tongue is made along the midline of the tongue until the root of the tongue. Then turn right angle to the side of the disease for a transverse incision straight to the tongue. At this time, it should be noted that the tongue muscle is cut layer by layer, the tongue artery is ligated, and the root of the tongue is traversed, and the specimen is taken off. 2. Stitching: First, pull the tip of the tongue to the front, and then suture the mucosa at the back of the tongue and the bottom of the tongue to prevent the tongue from twisting. Finally, remove the blood in the mouth and remove the wet saline gauze from the throat. complication Loss of appetite is one of the causes of cachexia and a clinical manifestation of cachexia. As with the cachexia of other advanced cancers, patients may experience loss of appetite or anorexia, weight loss, fatigue, anemia, and fever, severe failure and even death.
