Crooked nose is a common nasal deformity in which the position of the bridge of the nose deviates from the central axis, often accompanied by signs and symptoms such as deviated septum and nasal obstruction. Generally speaking, crooked nose can be corrected by crooked nose correction surgery, which can restore it to normal and achieve the purpose of cosmetic surgery. So, what are the key points of crooked rhinoplasty? Crooked rhinoplasty surgery points a: incision: routine disinfection after anesthesia, note that the incision has an intranasal approach and external nasal approach two kinds of incisions, each has its own advantages. The external nasal approach uses a U-shaped incision in the nasal columella, extending to the front edge of the nasal cartilage on both sides, and then separating the subcutaneous tissues upward, 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, making a curved incision and passing through the anterior edge of the septal cartilage to make the two sides of the incision united as one. After the incision is completed, the subcutaneous tissue can be widely separated upward, exposing the pyriform aperture and the inner nasal cartilage until above the nasal bone. At this time, care should be taken to avoid operating the dorsal nasal skin. Crooked rhinoplasty surgery points two: cartilage cone treatment of the nasal soft and bone scaffolding and the dorsum of the nose after extensive separation of the soft tissue, you can be from the septal epiphysis of the northern edge of the incision, so that the septal cartilage and the lateral cartilage detachment. Then, the wider side of the nasal cavity of the septum mucosa cartilage membrane flap and septal cartilage separation until the bottom of the nose, cut off the septum soft inner anterior edge and its vertical plate with the sieve bone and pear bone even pull, so that the septal cartilage is semi-free state. Crooked rhinoplasty surgery points three: bone cone processing according to the degree of bone vertebrae skewed by bone chisel or bone saw from the pear-shaped aperture edge upward, cut off the maxillary frontal protuberance and the nasal bone, with bone pincers clamped and twisted to make the upper end of the nasal bone fracture, at this time, the bone cone can be loosened, the nose with a finger to remove the plastic, observation of the nasal shape correction is satisfactory, you can suture the incision.
