The Analysis Of Postoperative Complications Of A Giant Dermoid Cyst In Third Ventricle And Interpeduncular Cistern By Extended Endoscopic Endonasal Approach Via Pituitary Transposition

Objective:To study the treatment effect and postoperative complications of resection of intracranial giant dermoid cyst between the third ventricle and interpeduncular cistern by extended endoscopic endonas-al pituitary transposition.Methods:The clinical data,surgical effect and postoperative complications of a female patient whose dermoid cyst between the third ventricle and interpeduncular cistern was resected by extended endoscopic endonasal pituitary transposition were analyzed retrospectively.To review the literature of traditional craniotomy and extended endoscopic endonasal pituitary transposition for the resection of midline tumors.Results:The giant dermoid cyst between the third ventricle and interpeduncular cistern was completely resected by extended endoscopic endonasal pituitary transposition.After the surgery,the patient had a transient diabetes insipidus and recovered completely without Permanent diabetes insipidus and permanent losing pituitary function.Conclusion:Extended endoscopic endonasal pituitary transposition forresection of dermoid cyst between the third ventricle and interpedun-cular cisternt which does not need to pull important brain tissues and blood vessels is a minimally invasive and effective surgical method.
