Abstract

To summarize the experiences in clinical application of neuronavigation in transsphenoidal microsurgery of specific pituitary adenomas, and to discuss its indications. From January 2006 to December 2010, 138 cases of transsphenoidal microsurgery for specific pituitary adenomas under neuronavigation were reviewed. The indications for neuronavigation in transsphenoidal microsurgery includes: recurrent or regrowth of residual pituitary adenomas after former transsphenoidal surgery in 36 cases, invasive pituitary adenomas in 45 cases, extremely laterally or deeply situated microadenomas in 45 cases, poor pneumatization of the sphenoid in 4 cases, skull base anomalies due to osteodysplasia fibrosa in 3 cases, narrow space between bilateral internal carotid arteries in 4 cases, distortion of nasal septum in 1 case. In the recurrence group, 12 were totally removed, 9 subtotally removed; postoperative complications included hematoma within the tumor cavity in 2 cases, cerebrospinal fluid (CSF) leakage in 4 cases among which 3 developed intracranial infection and 2 communicating hydrocephalus, oculomotor paralysis in 1 case and hypopituitarism in 3 cases; 9 were cured and 8 remission. In the invasive group, 5 were totally removed, 27 su...Continue Reading
