Postoperative cheek cyst extraction

Buccal cystectomy refers to the removal of maxillofacial cysts by surgery. Generally, maxillofacial cysts are more common in oral and maxillofacial cysts. According to their location, they can be divided into soft tissue cysts and jaw cysts. Its origins are odontogenic (such as root cysts, cysts containing teeth), retention (such as mucinous cysts, sublingual cysts) and embryonic development (such as facial fissure cysts, thyroglossal cysts, dermoid cysts, etc.). Among them, root cysts, mucinous cysts, and sublingual cysts are more common. Nowadays, "opening window decompression" is used to make the jaw cyst smaller, that is, the cheek cyst is removed and the cyst is completely scraped off by small surgery, and the ideal effect is obtained. Treatment of diseases: jaw cysts Indication Jaw cyst, facial subcutaneous cyst. Contraindications People with high blood pressure, heart disease, and mental illness. Preoperative preparation Regular use of antibiotics to prevent infection. Surgical procedure Incision Below the earlobe, the mandibular branch is in the middle of the posterior fossa, bypassing the mandibular angle, and then along the lower edge of the mandible 2 cm, parallel to the lower edge of the mandible, and reach the ankle forward. 2. Flap Cut the skin, subcutaneous tissue, platysma and deep cervical fascia along the design incision, ligation of the external and external veins of the jaw, and separate upward along this plane to reveal the lower edge of the mandible, and then cut the chewing muscle along the lower edge of the mandible. Attached to the periosteum and periosteum, the periosteal separator is used to peel under the periosteum and the tissue flap is turned up to reveal the mandibular angle and the mandibular humerus. 3. Stripping cysts Between the wall of the capsule and the bone wall, the wall of the capsule is carefully separated by a periosteal stripper. When peeling off, it is necessary to avoid damage to the alveolar vascular bundle. When the medial plate of the ascending branch of the jaw is damaged, it is necessary to prevent damage to the important internal anatomy such as the internal jaw artery and the pterygoid plexus. Other precautions and operating points can be referred to the intraoral mandibular cystectomy. However, it should be emphasized that after removal of the mandibular ascending cyst, the upper part of the ascending branch should be carefully examined to completely remove the residual wall. 4. Wound treatment Trim the edge of the bone wall, remove the bone debris, flush the bone cavity, and then suture the periosteum, the chewing muscle, place the half of the rubber tube in the wound cavity, and finally suture the deep fascia, platysma, subcutaneous tissue and skin incision . Facial compression bandage. For other treatments, refer to the intraoral method. complication The main complication of extraoral mandibular cystectomy is postoperative infection. The preventive measures can be removed from the buccal bone plate in cases of large mandibular cysts and thinner buccal bone plates, as described in the oral method. The lower margin of the mandible and the lingual bone plate are preserved, and the face is pressure-wrapped to shrink the wound cavity. At the same time, intermaxillary fixation is used to prevent pathological fractures. There is also a case where the buccal bone plate, the periosteum, and the buccal tissue flap are turned together and the cyst is removed, so that the buccal bone plate can be retained. It is worth emphasizing that keeping circulation is an important measure to prevent postoperative infection.
