Orbital wall fracture exploration

Causes of internal wall fractures, some are caused by direct blows on the inner edge of the nose and ankle, and more damage to the forehead of the maxilla, the cardboard and tear bone of the ethmoid sinus; some are caused by indirect burst injuries, the rim is normal, only the wall is fractured. Because the eyeball suffered a burst injury, its impact force was transmitted to the parties by hydraulic pressure. Relatively speaking, the sieving board is the thinnest, so the inner wall of the sputum is most prone to fracture. Treatment of diseases: orbital fractures of orbital fractures Indication The internal wall fracture. Contraindications 1. The general condition is weak and cannot withstand the operation; 2. Patients with bleeding tendency; 3. Adjacent tissues have infections without treatment control. Preoperative preparation 1. To guide the patient's anxiety, fear, and convulsions, to introduce the disease and surgical methods patiently and meticulously, to explain the necessity of surgery, analysis and prognosis, and to help patients improve their understanding of their own diseases; 2. Instruct patients to do some pre-operative personal preparations, such as washing their hair and bathing. Patients with long front hair should recommend cutting short hair to avoid contaminating the operation area. Surgical procedure 1. Repair the eyeball through injury in sequence. 2. Repair the inferior orbital wall fracture caused by the burst fracture. After the operation, the chin traction line is stuck in the forehead area to reduce the contraction scar in the incision area. 3, for lacrimal passage exploration to check the nasal lacrimal passage, if there is obstruction, according to the obstruction site for dacryocystorhinostomy or conjunctival sac capsular nasal anastomosis to restore lacrimal function. 4, if there is internal suede, you can make the opposite two Z-shaped plastic surgery correction. 5, for internal hemorrhoids and internal hemorrhoids fixation. (1) A soft contact lens is placed in each of the biconjunctival sacs. (2) 1.0-1.5cm before the internal hemorrhoids for H-shaped skin vertical incision, straight to the nasal periosteum, about 2cm long, such as only one side can cut one side. (3) Separate the skin, subcutaneous tissue, nasal fascia, orbital aponeurosis, find the medial malleolar ligament, and find out the fracture. If the broken bone piece pierces the periosteum, it should be taken out. (4) The fracture lines are connected by stainless steel wire, and the lacrimal sac is repaired if there is damage. (5) Puncture the nose with a No. 18 BD needle, pull out the needle core, and pass the two stainless steel wires through the needle core, then take out the No. 18 needle, take one of each pair of wires through the inguinal ligament, and then through the skin. A small splint is used on the medial malleolar ligament for fixation on both sides. (6) Suture the skin incision with a 6-0 silk thread, tighten the wire, and close the plastic splint to the nose to cut the wire stump. complication Bloody cerebrospinal fluid rhinorrhea; severe cases can cause traumatic ankle stenosis; when the nasal bridge is compressed, the internal iliac skin can be overlapped to form an internal sac, which can occur in various parts of the lacrimal duct. Dysfunction, tears can not be discharged.
