Lip Cancer V-Shape Resection

Lip cancer accounts for 1% to 4% of systemic cancer, and is the second most common malignant tumor in the head, face and neck. Most of the malignant tumors in the lips are squamous cell carcinoma, while sarcoma, spindle cell carcinoma, melanoma, etc. are rare. Lip cancer is superficial and sensitive to radiation therapy. Therefore, for a wider range of patients, radiation therapy can be performed first, and surgery should be considered after the tumor is reduced. The lymph of the upper lip skin and mucous membranes are drained to the ipsilateral ear, the ear, the back of the ear, and the submandibular lymph nodes; the lower lip is drained to the axillary lymph node and the ipsilateral or contralateral submandibular lymph nodes, and finally the deep cervical lymph nodes are injected. Lip cancer occurs in the lower lip of men, and only about 10% of cervical lymph node metastasis occurs, so many patients with lip cancer do not need lymph node dissection. However, if the regional lymph nodes are enlarged, the lymph nodes should be removed at the same time as the lip cancer is removed. Lip cancer is easier to diagnose, and patients are mostly early, so many patients can get better results with v-shaped resection. Treating diseases: lip cancer Indication Applicable to patients with surgical resection within 1/3 of the lower lip (or upper lip). Contraindications Regional nerve block anesthesia (upper lip block in the inferior tibiofibular and lower lip in the mandibular hole). Preoperative preparation Wash the mouth 1 to 2 days before surgery. Surgical procedure The following lip cancer v-shaped resection is an example. 1. Fixed point and scribing: first use a fine needle to smear the blue liquid, and set and scribe along the tangential line and the red edge of the lip. The tangent should be more than 1cm away from the cancer tissue. 2. Incision: The assistant uses the thumb and finger of both hands to pinch the edge of the lower lip of the bilateral mouth to control intraoperative bleeding. The surgeon then cuts the full lip v-shaped along the tangential line with a sharp-edged knife. 3. Separation of the orbicularis oculi muscle: After cutting the skin, subcutaneous tissue and mucous membrane of the entire lower lip, check whether there is any suspicious cancer tissue at the cut position, and expand the resection range if necessary. Then, a small sharp-edged knife is used to sneak a little between the subcutaneous tissue and the orbicularis muscle to prevent the skin from being wound during suturing. 4. Stitching: After careful hemostasis, the mucosa, muscle layer and skin are sutured intermittently from the mucosa by thin filaments. When suturing the skin, pay attention to the red edges of the lips. 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.
