partial maxillary resection

1. The maxillary odontogenic malignant tumor is confined to the alveolar process. 2. Tumors that are confined to the maxillary sinus floor. 3. Hard sputum tumors invade the basal wall of the maxillary sinus, or hard malignant low-grade malignant tumors, such as enamel, cylindrical tumor, epithelioid carcinoma and mixed tumor. Treatment of diseases: maxillary sinus malignancy, maxillary sinus cancer Indication 1. The maxillary odontogenic malignant tumor is confined to the alveolar process. 2. Tumors that are confined to the maxillary sinus floor. 3. Hard sputum tumors invade the basal wall of the maxillary sinus, or hard malignant low-grade malignant tumors, such as enamel, cylindrical tumor, epithelioid carcinoma and mixed tumor. Preoperative preparation 1. Should be used for x-ray film and nasal and sinus ct examination. Understand the extent of tumor invasion to determine the extent of surgical resection. 2. Preoperative preparation for general anesthesia. 3. Prepare blood. 4. Make the tray, cut off the hard palate and alveolar process due to surgery, in order to separate the mouth and nasal cavity after surgery, easy to restore chewing function. 5. Clean the mouth. Surgical procedure The scope of surgical resection is the alveolar process of the maxilla, the nasal floor and the hard palate, or the anterior wall of the maxillary sinus and part of the lateral wall of the nasal cavity. 1. The incision is determined according to the location of the tumor, and can be cut from the nasal wing to the nasal column, and then the upper lip is split in the middle to expose the lower part of the maxilla. Or a long incision in the affected side of the gingiva, incision of the periosteum, the incision in the medial incisor in the medial incision in the medial incision of the periosteum to the soft palate level, and then a transverse incision along the trailing edge of the hard palate to bypass the third molar It is connected to the labial incision. 2. Peeling the periosteum exposes the anterior wall of the maxillary sinus and the lower edge of a portion of the piriform hole, and peels the mucosa of the lower part of the nasal floor or the lateral side of the nasal cavity along the pear-shaped hole. 3. The hard palate mucosa was also peeled off and peeled off along the circumference of the tumor tissue by 1 cm. 4. The teeth, hard palate, the anterior wall of the maxillary sinus and the lower part of the lateral wall and part of the nasal bottom of the maxillary sinus are removed together with the tumor. 5. Clean up the surgical cavity. If there is residual tumor tissue, it should be thoroughly cleaned up to normal tissue. The wound in the surgical cavity is electrocauterized, and the blood is properly stopped. After filling the gelatin sponge, it is blocked with iodoform gauze, and it is taken out from the nasal cavity. Trust.
