Enlarged orbital content extraction

Content removal is a necessary treatment for malignant tumors. For the malignant and benign lesions of the eyelids, in order to save lives, relieve pain, improve appearance, and sometimes need to remove the content. Expanded sputum content removal refers to the operation of removing the bone wall invaded by the tumor after removing the sputum content. For example, a lacrimal gland malignancy should be removed along with the lateral wall and/or upper wall of the ankle, as appropriate. Treatment of diseases: adenoid cystic carcinoma Indication Expanded content removal is applicable to: 1. Lacrimal gland malignant epithelial tumors, such as adenoid cystic carcinoma, malignant mixed tumor extensive bone destruction. 2. Other primary malignant tumors invading the humeral wall. Surgical procedure After the removal of the content, the extent of bone removal is determined according to the location of the tumor invading the bone. If the tumor invades the upper wall of the iliac crest, the external wall of the iliac crest should be removed first. Then, the superior edge of the resected bone is advanced toward the dome to excise the dome bone. Specific operation: the dome can be opened with a grinding drill or a bone chisel, and the bone wall and the dura mater are separated by a periosteal stripper, and the dome is divided by a cone-and-plate pliers. If the dome has bone destruction and the dura mater has been exposed, the dome should be removed along the exposed portion, and the dura mater should be kept intact during the operation. Generally, the extent of bone resection is up to normal bone, or the full thickness of the bone wall is removed. Treatment of the sacral cavity: Due to the expansion of the sacral content, the sacral cavity communicates with the intracranial or paranasal sinus, so the sacral cavity after resection should be filled with tissue blocks, usually the diaphragm, the vascular pedicled fascia or A musculocutaneous flap with a vascular pedicle. If the sacral cavity and the paranasal sinus are not open, the eyelid can be sutured at the opposite end.
