A crooked nose is a common nasal deformity in which the bridge of the nose deviates from the central axis, often accompanied by symptoms and signs such as deviated nasal septum and nasal obstruction. Generally speaking, crooked nose can be corrected by crooked nose correction, which can be restored to normal through plastic surgery to achieve cosmetic purposes. So, what are the key points of crooked rhinoplasty? Crooked rhinoplasty surgery points a: incision: after routine disinfection and anesthesia, note that the incision has a nasal approach and nasal approach two kinds of incisions, each has its advantages. The external nasal approach uses a U-shaped incision in the nasal column, extending to the anterior edge of the nasal cartilage on both sides, and then separating the subcutaneous tissue upwards, this incision is a good exposure of the surgical field. The internal nasal approach incision is made at the upper edge of the nasal cartilage in the nasal vestibule on both sides, and a curved incision is made through the anterior edge of the septal cartilage so that both sides of the incision are united into one. After the incision is completed, the subcutaneous tissue can be widely separated upward to expose the pear-shaped foramen and the lateral nasal cartilage up to the nasal bone. At this point, attention should be paid to avoid operating the dorsal skin of the nose. Crooked rhinoplasty surgery point two: treatment of cartilage cone After extensive separation of the nasal soft inner and bony scaffold from the nasal dorsal soft tissue, the northern edge of the nasal septal epiphysis can be incised to detach the septal cartilage from the lateral nasal cartilage. Then, the mucous membrane cartilage flap of the septum on the wider side of the nasal cavity is separated from the septal cartilage up to the nasal base, and the anterior edge of the septal soft and its connection with the vertical plate of the sieve bone and the pear bone are cut off, so that the septal cartilage is semi-free. Crooked nose surgery points three: bone cone treatment according to the degree of bone vertebrae deflection with a bone chisel or bone saw from the edge of the pear-shaped hole upward, cut the maxillary frontal prominence and nasal bone, held in a bone clamp twisted to break the upper end of the nasal bone, at this time the bone cone can be loosened, nasal nudge plastic with fingers, observe the nasal shape correction is satisfactory, you can suture the incision.
