Mainly due to different materials, prosthetic rhinoplasty can be divided into silicone rhinoplasty and rhinoplasty. Generally speaking, under local anesthesia, a skin incision is made in one nostril (generally on the right side) along the medial and lateral foot front edges of alar cartilage, and instruments are used to dive under the nasal dorsal fascia to form a corresponding tunnel, then a silicone prosthesis is implanted, and the nose shape after implantation is observed from the front and side, and the distal end of the implant is best to reach the midpoint of the connecting line between the eyebrows and the inner canthus of both eyes, that is, the "golden section". If the length and height of the implant are appropriate, the contour curve of the nose is harmonious and natural, and the skin incision can be sutured. As for the question of which effect is better, cartilage rhinoplasty or prosthesis rhinoplasty, the two methods have their own advantages and disadvantages. The effect of cartilage rhinoplasty is lasting and not exclusive, and the prosthesis rhinoplasty has a good appearance, but the rhinoplasty effect only lasts for about ten years.
