Experience is the important point in reduction of the complications and in the effectiveness of the surgical procedure in pituitary surgery. Endoscopic pituitary surgery differs from microscopic surgery, since it requires a steep learning curve for endoscopic skills. In this article, we evaluate our learning curve in two groups, as early and late(More)
The endoscopic transsphenoidal approach has been reported in the literature as a useful tool to treat sellar and parasellar lesions. The endoscope permits a panoramic view instead of the narrow microscopic view, and it allows the inspection and removal of the lesions of sellar, parasellar, and suprasellar compartments by angled-lens endoscopes. On the basis(More)
Current literature reveals different opinions about the effectiveness of endoscopic third ventriculostomy in the treatment of hydrocephalus in children less than 2 years of age. Performing a retrospective evaluation of our own experience in this age group, we aimed to contribute to the growing data on the controversial issues related to this procedure in(More)
INTRODUCTION The management of epidural hematoma is classified into surgical or conservative treatment according to clinical and radiologic parameters.

OBJECT In this report, the authors describe their experience with surgical access to the cavernous sinus via a fully transnasal endoscopic approach in 20 cases. Clinical and endocrinological follow-up are discussed. METHODS The authors used an endoscopic transsphenoidal approach in 192 patients with pituitary adenomas between September 1997 and January(More)
BACKGROUND Visual field analyses reflect the degree of the compression to the optic nerve that results the structural damage of the nerve. These structural damages can be evaluated by diffusion tensor imaging (DTI), which assesses the structural integrity of white matter tracts. Thus, we evaluated the quantitative assessment of early visual recovery in(More)
The injury was performed with 600 g-cm/weight on the spinal cord of 40 cats with T8-9 laminectomy in this study. Ten cats were given 10 mg/kg naloxone i.v. 1 h after injury. Ten cats were given 2 mg/kg thyrotropin-releasing hormone (TRH) i.v. 1 h after injury followed by 1 mg/kg per hour for 4 h. Intravenous lidocaine was begun 30 min after injury in ten(More)
