Postoperative structural complications after microscopic transsphenoidal surgery of GH secreting pituitary adenomas

Objective: Analyzing the rate of structural complications after transsphenoidal surgery for removal of growth hormone (GH) secreting pituitary adenomas. Methods: Retrospective study of 58 patients who underwent microscopic transsphenoidal neurosurgery for GH secreting pituitary adenomas exeresis in Curitiba, Parana state, Brazil, between 1998 and 2011 by the same neurosurgeon. The Criteria for diagnosis of complications were clinical. Results: Five (8,6%) of the 58 patients who underwent transsphenoidal surgery developed postoperative anatomical complications, which was due to sixth cranial nerve palsy (3,4%), surgical wound infection (1,7%) and CSF fistula (3,4%). Conclusion: The rate of postoperative complications observed in the present study is likely the literature review. There is a drop in the rate of complications with increasing experience of the neurosurgeon.
