Document Type and Number:
WIPO Patent Application WO/2022/124797
Kind Code:
A1
Abstract:
The present invention relates to a nasal prosthesis. The present invention provides a nasal prosthesis and a method for manufacturing same, wherein the nasal prosthesis is inserted into the nasal bridge so as to correspond to the longitudinal direction of the nasal bone during plastic surgery and comprises, when being inserted into the nose, an outer portion which is in contact with skin tissue and is rounded convexly, and a rear portion which is in contact with the nasal bone and cartilage and has a curved surface, the nasal prosthesis having an average surface roughness (Sa) value of 5 µm or more and 49 µm or less. According to the present invention, since the average surface roughness (Sa) value of the nasal prosthesis is within the specific range as described above, the nasal prosthesis prevents, after being inserted into the nose, excessive fibrosis of the surrounding tissue, can inhibit the occurrence of capsular contracture, can reduce the occurrence of side effects such as positional distortion, and can be easily removed when side effects occur and thus facilitates revision surgery.
