The nose has the status of “king of the face” in the five senses. From the perspective of plastic surgery, oriental facial contours lack a sense of three-dimensionality and are flatter, while Chinese people have a majority of low and flat nose, especially in the south. If the face is flat and the nose is low, it will make the face look wider and flatter; if the nose is higher, it will make the facial contour more three-dimensional. Saddle nose is the most common nasal deformity in plastic surgery, manifested as the bone and cartilage part of the nasal bridge sunken inward, shaped like a saddle, the tip of the nose up, nostrils facing forward, commonly known as collapsed nose. 1.Preparation for rhinoplasty Before surgery, the patient’s nasal root and nasal back and tip should be repeatedly examined to understand the degree of saddle nose collapse, combined with the facial situation, the doctor fully communicates with the patient, grasps the patient’s requirements for treatment, determines the length, width, height and shape of the implanted body, does a good preoperative aesthetic analysis and preoperative design. 2, the incision and technology used in rhinoplasty generally choose the nostril medial edge small incision, through the nasal cartilage between up to the nasal dorsal fascia, the nasal dorsal fascia from the periosteum, to the nasal root gold point, after filling rhinoplasty to prosthesis position fixed, do not move around, curvature height width and other forms to achieve satisfactory results, after the incision suture, after surgery does not leave any trace. 3, the choice of filling materials for rhinoplasty Currently, the world’s commonly used filling materials are solid silicone and GORD TEX (GORD TEX) tumescent material (EPTFE). Silicone has the advantages of stable performance, low irritation, moderate texture, easy to shape, durable and non-deformable, easy to operate and less painful for patients, very few post-operative complications, easy to remove and restore the original appearance, suitable price, etc., as the most commonly used filling material. GORD TEX (GORD TEX) expansion material (EPTFE) has good biocompatibility and unique microporous structure, in the body after placement of human tissue cells and blood vessels can grow into its microporous, so that the expansion material and surrounding tissues into one, smooth transition between the prosthesis and surrounding tissues, post-operative appearance better than silicone, especially those with a low nasal bridge nasal dorsal soft tissue less thin patients feel the overall shape more natural. 4.Surgical precautions The nose will be swollen after surgery, 48 hours after surgery is the peak of swelling, 2 to 3 days is more obvious, after that the swelling gradually in a week to subside, after surgery generally 4 to 6 days to remove the sutures. Female candidates are advised to avoid surgery during their menstrual period.
