nasal incision

Nasal incision is a wide-ranging treatment of the nasal cavity and sinus from the extranasal route. Up to the frontal sinus and ethmoid sinus can be reached upwards, down to the sinus floor of the nasal cavity, the medial side can treat the lesion on the nasal septum, and the lesion in the maxillary sinus can be treated outward, reaching the sphenoid sinus backward, which is widely used in clinical application. One of the surgeries. Treatment of diseases: nasolabial nasal hemangioma Indication 1. Large benign tumors in the nasal cavity, such as papilloma, fibroids, hemangioma and osteoma. 2. Large benign tumors in the ethmoid sinus, maxillary sinus and sphenoid sinus can not be completely removed by intranasal route. 3. Nasal ethmoid malignant tumor or lacrimal sac cancer invades the ethmoid sinus. 4. Nasopharyngeal tumors that mainly extend to the nasal cavity are difficult to remove by hard palate. Preoperative preparation 1. Preoperative sinus tablets, or body slices, or sinus ct examination, fully understand the primary site of the tumor, the extent of erosion, and develop a surgical plan. 2. According to general anesthesia preparation, should be treated according to internal medicine doctors before surgery. 3. Prepare blood. 4. Clean the skin and trim the nose hair. Surgical procedure 1. The incision is slightly above the medial side of the medial malleolus. About 5 mm begins to cut the skin along the nose, bypassing the nose to the nasal column, and cutting the bone. 2. Exposing the nasal cavity along the periosteum, exposing the nasal bone, the maxillary frontal process and the bone around the piriform hole. The lower edge of the nasal bone was peeled off with a stripper, and the soft tissue of the outer wall of the nasal cavity was separated from the bone along the edge of the pear-shaped hole. The nasal bone was bitten by the rongeur to the horizontal line of the internal iliac crest, the edge of the piriform hole was enlarged, and the mucosa of the outer wall of the nasal cavity was opened to expose the nasal cavity. And tumors. 3. Explore the maxillary sinus to open the anterior wall of the maxillary sinus and explore the lesions in the maxillary sinus. Cut the maxillary frontal process. The outer edge of the pear-shaped hole is cut at the level of the bottom of the nose, and then the tumor is removed together with the outer side wall of the nasal cavity. 4. Exploring the ethmoid sinus to remove the upper part of the lateral wall of the nasal cavity and the middle turbinate, and enter the ethmoid sinus. Open the sphenoid sinus if necessary. 5. After the lesions in the surgical cavity are completely removed, the wound is electrocauterized, then covered with Vaseline gauze, the iodoform gauze is blocked, and the incision is sutured and pressure-wrapped.
