Randomized Controlled TrialTopical anesthetic EMLA for postoperative wound pain in stereotactic gamma knife radiosurgery: a perspective, randomized, placebo-controlled study.
Patients who undergo stereotactic gamma knife radiosurgery (GKRS) need a rigid frame fixation for the stereotactic procedures. Many patients suffered from postoperative wound pain after frame removal. The present study investigated whether an additional application of a topical anesthetic prior to frame removal could reduce this discomfort. ⋯ EMLA when applied 60 min before frame removal has an anesthetic effect of reducing the postoperative wound pain in patients who undergo GKRS.

Since the first reported endoscopic treatment of colloid cysts of the third ventricle by Powel et al. in 1983, several endoscopic techniques have been described. Therefore, the authors describe their technique of neuroendoscopic colloid cyst removal, developed during the last 16 years. ⋯ With the described endoscopic technique, complete removal of colloid cysts is possible in almost 90 % of cases.
