62 cases of parapharyngeal space neoplasms Report

. Can be found above the clinical 0cm. The patients treatment when tumors were larger, and the patient in the clinic when the corresponding varying degrees of pressure on adjacent organs and structure of the symptoms. From this group of cases can be seen, pain and limited mouth opening with a malignant lesion often prompts tendencies. Palpation of the initial specific tumor size, and scope of activity has a certain significance, pulsatile mass with vascular disease often prompt, but the rhythm is sometimes caused by conduction will be mistaken for vascular disease, so palpation alone is not reliable . Imaging in the diagnosis of parapharyngeal tumors is of great significance. CT, MRI can clearly invasion and tumor size and scope,[link widoczny dla zalogowanych], B-to clear the nature of the tumor and its surrounding relations between the great vessels, angiography is clear the blood supply of tumors and vascular origin, and possible embolization , of great value in reducing blood loss. Parapharyngeal space tumor pathology varied. Parapharyngeal space and parotid salivary gland tumors may be derived from salivary gland tissue outside, but the most common site is the deep lobe of parotid gland, followed by the mandibular gland of the rear end. Benign and malignant tumors in which the odds ratios reported in the literature range from 24-75,[link widoczny dla zalogowanych], very different. Pharynx 485 * next to the space of neurogenic tumors or nerve sheath tumor of Schwann cell tumors, said the most common predilection sites for the vagus nerve or sympathetic chain, in this article about 50 of the cases from the vagus nerve, consistent with the literature. The patients, 3 cases of neurofibromatosis complicated by parapharyngeal space parapharyngeal space tumor is a special case of the tumor. Schwannoma is slowly growing tumors, generally do not affect the function of the nerve, but with the tumor growth will lead to loss of nerve function. In addition to the vagus nerve, the hypoglossal nerve is also a source of nerve sheath tumors. This article from the hypoglossal nerve in 1 case. Occurred in the parapharyngeal space paraganglioma can come from the vagus nerve and carotid body, to the 1988 date, 150 cases reported in the literature world in vagal paraganglioma ∞. 2 cases in this group from the vagus nerve. Typically, about 2 / 3 of vagal paraganglioma located in the parapharyngeal space, compared with carotid body tumors are rarely extended to the parapharyngeal space, the rate was 8 to 30. This rare pathology of other types of vascular tumors, aneurysms, lymphoma, rhabdomyosarcoma, inflammatory pseudotumor, meningioma, etc. have been reported in previous papers ∞, but the malignant Triton tumor of the parapharyngeal space has not been reported. The group also parapharyngeal space is the first report of metastatic liver cancer. Primary tumor in the parapharyngeal space require surgery. Used in this paper,[link widoczny dla zalogowanych], the path of several operations, carried out by the oropharyngeal pathway for the early years of operation,[link widoczny dla zalogowanych], only suitable for small tumors. The drawback is the blind surgical procedures,[link widoczny dla zalogowanych], easily lead to broken or the removal of the tumor is not complete, also increase the chances of infection. Sides of neck approach respected by many authors, but the larger the tumor revealed the tumor is not sufficient, could easily lead to fragmentation and the residual tumor, the group had 2 cases of tumor recurrence. So in order to expand the surgical field, often to be done to cut off the mandible in various ways, but the osteotomy itself can bring about the corresponding problem. Recently, the author mainly uses the neck of a gland into the road, not a tumor recurrence. Neck surgery for a parotid approach can identify the facial nerve and parotid gland forward lift, the vision spacious, vast majority of cases without the mandible truncated. I only 1 patients with malignant pharyngeal wall due to the direction of the violations, the median split of mandibular complete removal of the tumor. Therefore, resection of the neck of a gland into the parapharyngeal space tumor surgery after all, a good path.
