Diagnosis and treatment of cavernous sinus neurinoma / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the diagnosis and microneurosurgical treatment of cavernous sinus neurinoma.</p><p><b>METHODS</b>Twenty-two patients with cavernous sinus neurinoma which had been diagnosed by MRI were operated on by microsurgery. Fourteen patients received excision of tumor through frontotemporal approach with zygomatic osteotomy and, 8 patients via subtemporal and suboccipital transtentorial approaches.</p><p><b>RESULTS</b>Total resection was achieved in 21 patients (95.5%), and subtotal resection in 1. There was no operative death. The all operative samples were confirmed neurinoma pathologically. The symptoms postoperation such as headache and exophthalmos were reduced. Three months after operation, the function of the 6th nerve was improved in 12 of 19 patients with paresis of the 6th nerve. One patient with hemiplegia recovered well. The function of the 3th nerve recovered in 4 of 6 patients with recurrent paresis of the 3th nerve. Those patients with hydrocephalus were improved after operation. The patients were follow up 8 - 60 months (mean 20 months). No tumor recurrence was observed.</p><p><b>CONCLUSION</b>Cavernous sinus neurinoma can be removed successfully via subtemporal and suboccipital transtentorial approaches.</p>
