ligation of ethmoid artery

1. Severe bleeding above the free edge of the middle turbinate (mostly after head and face trauma), failed by stuffing or other hemostasis measures. However, nose bleeding due to rupture of the intracranial aneurysm should be excluded as much as possible. 2. When the ethmoid sinus surgery (scraping, tumor resection, foreign body removal, etc.) is performed outside the nasal route, the first artery ligature ligation can reduce intraoperative bleeding. Treatment of diseases: traumatic nosebleed aneurysms Indication 1. Severe bleeding above the free edge of the middle turbinate (mostly after head and face trauma), failed by stuffing or other hemostasis measures. However, nose bleeding due to rupture of the intracranial aneurysm should be excluded as much as possible. 2. When the ethmoid sinus surgery (scraping, tumor resection, foreign body removal, etc.) is performed outside the nasal route, the first artery ligature ligation can reduce intraoperative bleeding. Preoperative preparation 1. Take the sinus and the lateral position of the skull and the skull base to understand the ethmoid sinus and sphenoid sinus. 2. Prepare a small silver clip for brain surgery. Surgical procedure 1. Incision. 2. Along the periosteum, peel off the posterior superior wall of the iliac crest. Use the hook to push the tissue inside the eyelid to the outside, expose the eyelid floor, tear bone, on the frontal sieve or slightly above it, about 2~2.5cm away from the skin cutting edge, and see the vascular nerve bundle penetrate into the anterior mesh hole. 3. Separate the anterior ethmoid artery with a small blunt hook, ligation with a silk thread, or use a small surgical silver hemorrhage clip to clamp the artery, but do not have to cut the blood vessel. 4. If the anterior ethmoid artery is ligated, if the bleeding is still not enough, it can be peeled back along the forehead sieve. After deepening about 1cm, the posterior stencil and the posterior sacral artery can be found. Because of the deep position and close to the optic nerve, ligation is quite difficult. Generally, it can be cauterized with a silver clip or a bipolar coagulator. 5. After stopping the bleeding and cleaning the operation cavity, the incision is sutured in two layers.
