buccal parotid duct reconstruction

Buccal mucosa reconstruction of the parotid gland is used for reconstruction of the parotid duct. Paralysis of the parotid duct due to trauma or surgery may cause leakage or loss of the catheter. Therefore, catheter reconstruction must be actively carried out. Various reconstruction procedures are selected based on their indications. In recent years, the author (unit) has succeeded in using the proximal gland end anastomosis of the vein and residual catheter in the front. Treatment of diseases: buccal infection Indication Buccal mucosal parotid duct reconstruction is suitable for short residual ducts in the proximal gland, and it is difficult to use end-to-end anastomosis or catheter diversion. Contraindications There are lesions in the buccal mucosa. Preoperative preparation 1. Inject methylene blue from the mouth and the catheter mouth 1 day before surgery; prepare a lacrimal sac probe and a hollow hose. 2. Determine the injury site by parotid angiography. 3. Remove intraoral infections. 4. Other routine preparations before oral and maxillofacial surgery. Surgical procedure 1. Incision The incision was made with the catheter outside the mouth, and the buccal mucosa was made into the incision in the mouth. 2. The rebuilt catheter is connected to the residual conduit First, the residual duct of the proximal gland is freed, and then the buccal mucosa tongue flap is designed according to its length. The width of the tongue is generally between 1 and 1.5 cm, and the pedicle is at the front of the chewing muscle. After the mucosa and submucosal tissue are dissected, the lobes are sewed into a tube, and the base is not sutured as an opening. At the basal wound of the valve, the buccal muscle was bluntly separated, and the prepared mucosal tube was passed through it, placed on the surface of the buccal muscle, and the prepared catheter stump was sutured with a 5-0 nylon thread. 3, stitching The outer wound was sutured in layers, and the wound in the mouth was sutured in a single layer. The new catheter is also inserted into the hollow hose and fixed. Facial wound dressing.
