How to treat a wound with recurrent watery symptoms after facial trauma? Due to the exposure of the face, it is easy to be injured in daily life. Most of the water flowing after facial trauma is caused by parotid gland injury. Depending on the location and extent of the injury, it is clinically divided into ductal injury and glandular injury; ductal injury clinically involves the parotid duct, so that the duct is interrupted and saliva does not flow into the oral cavity, but flows to the facial wound, and there is no secretion even at the mouth of the parotid duct on the side of the wound; glandular injury: due to traumatic injury, the glandular vesicle is broken, the secretion at the mouth of the parotid duct on the side of the wound is basically normal, and there is a small amount of saliva repeatedly spilling out of the facial wound. The facial wound has a small amount of saliva spillage. Treatment of glandular injury: pressure bandage on the facial wound, avoid eating spicy, stimulating and acidic foods, take 0.6mg of atropine orally half an hour before each meal to inhibit salivary gland secretion, generally 10-14 days to heal; ductal injury: should be carefully examined at the time of trauma suturing, first interrupt ductal anastomosis, rerouting and reconstruction according to the situation; then pressure bandage on the wound, avoid eating spicy, stimulating and Acidic and other foods, oral administration of 0.6 mg of atropine half an hour before each meal to inhibit salivary gland secretion, generally 10-14 days to heal.
