Application of Platelet-Rich Plasma in Nasal Tip Reconstruction with Medpor Prosthesis

Objective: To observe the effect of platelet-rich plasma (PRP) on reducing ear cartilage absorption and nasal tip complications after nasal tip plasty with medpor prosthesis. Methods: During the conventional medpor rhinoplasty, PRP was injected locally around the tip and columella of the nose with medpor material. The morphology of the nasal tip cartilage and the shape of the nasal tip were observed at least 1 year after the surgery, and the status of cartilage absorption was judged. The statistical differences between the control group and the experimental group were analyzed by χ²-test. Results: After observation for 1 year, a total of 71 cases underwent conventional medpor rhinoplasty, of which 21 cases had cartilage resorption, and 10 cases had a prominent shape of the nasal tip prosthesis that required repair; In the platelet-rich plasma treatment group, there were 18 cases, 1 case of cartilage absorption, and 0 case requiring repair. There are significant statistical differences in clinical practice. Conclusion: PRP can significantly reduce the absorption of ear cartilage, maintain the appearance of the nasal tip, and improve the satisfaction of patients with medpor prosthesis rhinoplasty.
