Analysis the causes of surgical complications of medial sphenoidal ridge meningioma

Objective To discuss the causes and precautions of postoperative complications of medial sphenoidal ridge meningioma.Method The clinical data of 38 cases of medial sphenoidal ridge meningioma operated between May 1995 and May 2005 were analyzed retrospectively.Results Twenty eight eases of medial sphenoidal ridge meningioma got total resection,eight cases got subtotal resection,and the other two cases were partially resected.Without thorough understanding of the anatomy of facial nerve,facial nerve injuries oecured in 2 cases;ooulomotor nerve injuries occurred in 6 cases;beth of the two nerve injuries might result from inappropriate procedure;injury of caveruous sinus was involved in total tumor resection,which led to the simultaneous injury of oculomotor nenre trochlear nerve and abducens nerve in 2 cases;2 cases presented optic nerve injuries due to the injuries of the adjacent arteries;too early resection of tumor-related vessel caused middle cerebral artery injury in one case and lenticulostriate artery injury in 2 cases.Conclusions With careful,extensive preoperative evaluation and appropriate planning of the surgical approach,as well as revolutionary invention of surgical techniques,medial sphenoidal ridge meningioma can be radically and safely resected without any severe complications.
