parotid duct stone removal

Parotid duct stone removal is used for the treatment of parotid duct stones. Parotid duct stones are far less common than submandibular duct stones. The ratio of the submandibular gland to the parotid gland is about 12:1. Treatment of diseases: parotid gland infection Indication Parotid duct stone removal is suitable for: 1. There are obstructive symptoms, and those who cannot be discharged after conservative treatment. 2. After parotid angiography, the catheter was found to have pathological changes. Contraindications 1. Local infections should be suspended. 2. Acute inflammation due to obstruction of the catheter. Preoperative preparation 1. Diagnosis: The location of the stone is determined by X-ray plain film or B-ultrasound examination, and it is also differentiated from the venous stone of the hemangioma. The difference between the two is the difference in medical history and physical signs. 2. There should be a hollow hose with color before surgery. 3. Other routine preparations for maxillofacial surgery. Surgical procedure Incision Stones at the proximal opening of the catheter should be taken as an intraoral incision. Although most catheter stones are at the leading edge of the catheter near the chewing muscle, efforts should be made to make an incision in the mouth, and try to avoid making a skin incision directly on the cheek. An arcuate incision of the buccal mucosa is usually performed about 5 mm in front of the parotid duct. 2. Reveal After the mucosa and submucosal tissue were dissected, the catheter and stones were explored. After touching the stone, the line was passed through the deep end of the catheter at the proximal gland end and lifted to prevent the stone from moving in the duct to the gland end. 3. Take the stone Depending on the size of the stone, a longitudinal incision is made along the direction of the catheter, and the catheter is cut open to remove the stone. Then, the hollow rubber tube is inserted into the catheter, and the cut catheter is intermittently sutured. The wound in the mouth was closed in layers, and finally the hollow rubber tube was fixed at the buccal mucosa and the pressure was wrapped outside the mouth.
