Dermoid cyst resection of the floor of the mouth

Curing disease: Indication When the oral dermatoid cyst grows up, it can affect the function of speaking, eating and breathing, and can also cause dental malformation, so it should be removed surgically. Surgical procedure Incision A skin incision parallel to the lower edge of the mandible 2 cm from the lower edge of the mandible is about 4 to 5 cm long. 2. Reveal the cyst Cut the skin, subcutaneous tissue and platysma according to the incision design, retract the flap up and down, separate the upper boundary to the lower edge of the mandible, the lower boundary to the level of the hyoid bone, and then pull the anterior abdomen of the two abdominal muscles to the left and right. The cyst can be revealed. 3. Stripping cysts Due to the thick wall of the capsule, blunt separation along the wall of the capsule allows the cyst to be removed smoothly. However, the cyst can be extended to the bottom of the mandible by the mandibular lingual muscle or between the mandibular lingual muscle and the genioglossus muscle. At this time, the mandibular lingual muscle should be cut from the midline and pulled to the sides to reveal the deep cyst after the mouth. Continue to blunt separation along the wall of the capsule. 4. Remove the cyst The cyst was pulled outward and bluntly separated between the wall of the capsule and the genioglossus until the cyst was completely stripped and removed. 5. Stitching After rinsing the wound and completely stopping bleeding, suture the muscle layer, eliminate the invalid cavity, place a rubber strip or half tube drainage, and suture the wound layer by layer. The crotch is properly pressure bandaged. complication Intraoperative complications include sublingual glandular injury, submandibular gland catheter injury, lingual nerve injury, and deep tongue and vein injury. However, due to the thick wall of the capsule, as long as the blunt separation along the surface of the capsule wall, the above important anatomical structure can be avoided. Postoperative complications mainly include oral bleeding and edema, and upper respiratory tract obstruction due to hematoma compression. Therefore, during surgery, attention should be paid to reducing trauma. At the end of the operation, the bleeding should be completely stopped. At the same time, the drainage strip should be placed. The postoperative observation should be closely observed. If the swelling of the mouth is developing rapidly, it is necessary to detect the hemostasis in time to prevent suffocation.
