How long does tuberculum sellae meningioma recur after operation?
summary
Tuberculum sellae meningioma was first introduced by Stewart in 1899. Cushing called it suprasellar meningioma in 1929. Meningiomas originated from tuberculum sellae, anterior clinoid process, septum sellae and sphenoid plateau. Because the range of the above anatomic structures is less than 3cm, the tuberculum sellae meningiomas are commonly called tuberculum sellae meningiomas. The suprasellar meningiomas arising from cribriform plate, sphenoid ridge and clivus are not included in this category because of the differences in clinical manifestations, imaging findings and surgical methods. Next, how long does tuberculum sellae meningioma recur after surgery?. Hope to help you.
How long does tuberculum sellae meningioma recur after operation?
First, pituitary adenomas are usually characterized by endocrine disorders. More than 70% of patients have endocrine disorders, and more than 50% of patients have this as their first symptom. In the early stage of optic nerve compression, visual field defect was the main cause, and the change of visual acuity was not obvious. About 97% of the patients showed enlargement, deformation or bone destruction of sella turcica.
Second, craniopharyngiomas are mostly younger, with obvious symptoms of hypothalamus involvement such as diabetes insipidus and obesity. 66% - 74% of the patients have suprasellar and / or intrasellar calcification, especially eggshell calcification, which is more valuable for the diagnosis.
Third: the visual acuity of arachnoiditis at optic chiasma decreased slowly, and the symptoms were often relieved. The visual field changed irregularly. The sella turcica was normal. There was no bone hyperplasia and destruction near the sellar tubercle. There was no mass shadow in the sellar area on CT scan.

Prognosis: early small tumor, surgery can be completely removed and cured, the mortality is very low. If the tumor is large, the risk of operation will increase. According to the literature, the mortality of this disease varies greatly (2.6% - 67.0%). The postoperative visual acuity and visual field were improved in 27.8% - 72.2% of the patients, but still deteriorated in 5.6% - 38.9% of the patients. Rosenstein et al. Believed that the postoperative visual acuity recovery was related to the following factors: the preoperative visual impairment was more than 2 years; The tumor diameter was less than 3 cm; Preoperative visual acuity was not less than 0.7; Fundus examination showed that the optic disc was normal. For those meningiomas of tuberculum sellae that can not be completely resected, postoperative radiotherapy can be performed. For recurrent meningiomas affecting visual acuity, reoperation should be considered.
