RESUMO
Objective To explore the effect of neuroendoscopic surgery for the removal of medium and large sized tuberculum sellae meningiomas through supraorbital keyhole approach.Methods A retrospective research was performed on 7 case of patients with tuberculum sellae meningioma who underwent endoscopic surgery through supraorbital keyhole approach.The main performance of patients as tumor diameter were 2.8-4.7 cm and the skin incision located at superciliary aich which size of intra-frontal bone window was 3.5 cm× 2.0 cm.Results Total removal was achieved in 7 cases(simpson Ⅰ grade in 2 patients,sirnpson 1Ⅱ grade in 5 patients).Postoperative,the visual outcomes of eyes were showed improvement in 9 eyes,remained steady in 3 eyes,and deterioration in 2 eyes.All patients were followed up for 6-13 months and no recurrence was found.Conclusion Neuroendoscopic surgery through supraorbital keyhole approach is an effective method for the resection of medium and large sized tuberculum sellae meningiomas.
RESUMO
Objective To explore the clinical characteristic of Rathke′s cleft cyst and assess the effect of endoscopic en-donasal transsphenoidal surgery .Methods A retrospective research was performed on 9 patients who underwent endoscopic en-donasal transsphenoidal surgery .Neural endoscopic surgery by single nostril transsphenoidal approach ,partial resection of the cyst wall with drainage of the intracystic contents was performed in all patients .Results Symptoms in all patients were resolved or alle-viated .No CSF rhinorrhea ,permanent diabetes insipidus and hypopituitarism happened .All patients were followed up for 4 to 12 months and no recurrence was found .Conclusion Endoscopic endonasal transsphenoidal surgery is a effective method for symptom-atic Rathke′s cleft cysts .
