Abstract:
Objective: To examine the clinical effect of simple muscle packing through transnasal sphenoid approach in the treatment of intrasellar arachnoid cyst. Methods: The clinical data of 11 patients with intrasellar arachnoid cyst treated by transnasal sphenoidal approach with simple muscle packing at the Neurosurgery Department of the First Affiliated Hospital of Zhengzhou University from January 2014 to February 2020 were retrospectively analyzed. There were 5 males and 6 females, with a median age of 48 years (range: 23 to 75 years). The clinical manifestations included headache in 6 cases, dizziness in 4 cases, hypo-libido in 1 case, disturbance of consciousness in 1 case, visual impairment in 7 cases and mixed pituitary dysfunction in 5 cases. The enlargement of the sellar fossa was seen in the preoperative MRI images. The enhanced MRI images showed that the cyst wall of the intrasellar arachnoid cyst was not enhanced, and the compression and thinning of the sellar base was seen in the CT images. In 9 cases, the cyst extended suprasellar and the sellar septum was "arched". In 7 cases, the cyst compressed the optic chiasm upward. The cyst walls of all patients were incised through the nasal sphenoid approach under the endoscope, and the muscle was packed after sufficient drainage. The postoperative symptoms, pituitary endocrine function and recurrence of patients were followed up. Results: MRI images of the sellar region in all patients showed significant reduction or disappearance of cysts. Intracranial infection occurred in 1 case and electrolyte disorder in 2 cases, which were relieved after symptomatic treatment. No cerebrospinal fluid rhinorrhea occurred. Postoperative clinical symptoms were completely relieved in 6 cases and partially relieved in 5 cases. Pituitary endocrine function recovered completely in 2 cases and improved significantly in 4 cases. All patients were followed up for 10 to 40 months. One patient found to have a partial recurrence of the cyst 3 months after surgery. Because there were no new symptoms appeared, the follow-up was continued without second operation. Conclusion: Transnasal sphenoidal approach is a feasible method for the treatment of intrasellar arachnoid cyst.
