Minimally invasive surgery for oral polyps includes local anesthesia, removal of polyps, suturing and other processes. 1. Local anesthesia: In order to avoid postoperative recurrence, the initiating factors are dealt with before surgery. Oral polyps are usually preceded by local infiltration anesthesia. Polyps should be judged whether there is inflammation, mechanical irritation and other causes. 2. Excision of polyps: cut through the mucosal layer, submucosal layer, superficial surface of the muscle layer complete excision of polyps. After anesthesia takes effect, the tissue around the swelling makes a shuttle incision. If the polyp is attached to the fascia of the muscular layer, it is necessary to remove part of the fascia and muscle. 3. Suture: After checking for active bleeding, the mucosa is sutured intermittently. Rinse the wound with saline after polypectomy. If you need to remove oral polyps, you need to go to a regular medical institution to avoid delays.
