ethmoid sinus foreign body removal

Foreign bodies of the sphenoid sinus are mostly opaque foreign bodies. The foreign body often stays at the bone wall between the posterior ethmoid sinus and the sphenoid sinus. If the foreign body stays on the sinus floor or the tip of the sinus, it will cause obstacles in eye movement, decreased vision, and even blindness. Therefore, the treatment of sphenoid sinus foreign bodies must be cautious. Especially those with close eyelids and good eyesight should be treated more seriously. Treatment of diseases: sphenoid sinus malignant tumor Indication Foreign bodies of the sphenoid sinus are mostly opaque foreign bodies. The foreign body often stays at the bone wall between the posterior ethmoid sinus and the sphenoid sinus. If the foreign body stays on the sinus floor or the tip of the sinus, it will cause obstacles in eye movement, decreased vision, and even blindness. Therefore, the treatment of sphenoid sinus foreign bodies must be cautious. Especially those with close eyelids and good eyesight should be treated more seriously. Preoperative preparation 1. Preparation for general anesthesia should be done, including electrocardiogram, chest X-ray, liver and kidney function tests and routine examination of hematuria. 2. Ophthalmology consultation should be consulted to understand the changes in eye movement and fundus, and if necessary, visual field examination. 3. X-ray sinus positive lateral radiograph, is very important for the location of foreign bodies, and has a certain guiding effect on the smooth operation of the operation. Surgical procedure There are two ways. (a) transnasal ethmoid sinus pathway 1. Incision from the nasal side, first remove the ethmoid sinus and reach the anterior wall of the sphenoid sinus 2. Open the anterior wall of the sphenoid sinus, according to the positioning of the X-ray film, look for foreign objects. If necessary, mark the position of the foreign object with a probe under X-ray fluoroscopy, and then use the foreign body clamp to approach and remove the foreign object along the direction of the probe. The Hopkins endoscope can also be inserted into the sphenoid sinus with a 0° or 30° viewing angle to find foreign objects, and the foreign body can be taken out under endoscope direct vision. (B) through the maxillary sinus 1. First make a lip and sulcus incision, open the anterior wall of the maxillary sinus like maxillary sinus radical surgery. 2. After the upper anterior wall of the maxillary sinus is scraped off, the posterior sinus sinus is scraped off, and the air chamber is completely opened to expose the anterior wall of the sphenoid 3. After opening the anterior wall of the sphenoid sinus, look for the foreign body in the direction of the X-ray film and remove the foreign body. Foreign bodies can also be removed under direct vision using a Hopkins endoscope with a 0° or 30° viewing angle. Intraoperative bleeding of the arteries after sieving should be ligated or electrocauterized. Stop the occlusion by ethmoid sinus or maxillary
