Repair of orbital floor fractures

Old fractures of the fundus, the eye position decreased, and the eyeball was restricted. Treatment of diseases: orbital fractures Indication Old fractures of the fundus, the eye position decreased, and the eyeball was restricted. Contraindications The age of the body is weak, the vital organs such as the heart and lungs are poor, and the surgery does not restore hope. Preoperative preparation You should fast for eight hours before surgery, and you can drink half a cup or less of water (barley tea) three hours before surgery, but you cannot drink milk or orange juice. Prohibition of alcohol should be done the day before surgery, and excessive weight loss, taking diuretics, taking aspirin, and excessive smoking before surgery can have adverse effects on surgery. Before the operation, the patient and his family should be explained that the operation only loosens the adhesion at the bottom of the sputum and uses a filling pad on the bottom of the sputum to lift the eyeball. Therefore, the appearance is improved, the eye movement is improved, and the double vision may be reduced. Not necessarily fully recovered. Because it may have a fracture of the medial side wall, the sputum into the sinus sinus, as well as extraocular muscles, nerves and other injuries. Surgical procedure Subperiosteal hydroxyapatite filling 1. There are two options for surgical incision. 1 Cut the skin and orbicularis muscle along the lower inferior temporal margin below the inferior temporal margin and expose the lower margin. 2 2cm parallel to the inferior temporal margin of the eyelash edge, and the incision was made in the lateral malleolus along the upper edge of the iliac crest. Cut the skin and the orbicularis muscles. The center of the inferior temporal margin is used as a traction suture, which is sneaked apart between the orbicularis oculi and the tarsal plate to the inferior temporal margin. 2. The periosteum was cut under the gingival margin along the inferior iliac crest, and the detachment was used to sneak away along the lower iliac crest toward the apex. The adhesion between the periosteum and the tibia is cut off to make it a subperiosteal space. 3. Carefully deliver the prepared hydroxyapatite plate into the subperiosteal space. The hydroxyapatite plate is roughly triangular in shape, and the thickness is slightly smaller than the downward movement of the eyeball. The base of the triangular plate is about 2 cm wide and the depth is 2 to 2.5 cm. When the subperiosteal space is placed, the base portion is flush with the lower rim. Immediately compare the two eyes. For example, the eyeball is still lower than the healthy eye, and the second hydroxyapatite plate can be implanted according to the difference distance. For example, if the eyeballs of the two eyes are higher than the healthy side, or the original implanted plate is taken out, it is adjusted with a scalpel or a sputum, or the hydroxyapatite plate is pressed in the rim of the rim. If the eyeball and the eyeball are close to each other, the upper jaw depression will also be significantly improved. 4. Intersect the periosteum. Layer suture the orbicularis muscle and skin. Compression dressing. complication eye pain.
