Hearing Preservation after Low-dose Gamma Knife Radiosurgery of Vestibular Schwannomas
The objective of the retrospective study was to evaluate the factors associated with hearing preservation after low-dose Gamma Knife radiosurgery (GKS) of vestibular schwannomas performed according to the modern standards. From January 2005 to September 2010, 141 consecutive patients underwent such treatment in Tokyo Women's Medical University. Mean marginal dose was 11.9 Gy (range, 11-12 Gy). ...
متن کاملLong-term follow-up after stereotactic radiosurgery of intracanalicular acoustic neurinoma
BACKGROUND The management of solely intracanalicular acoustic neurinoma (iAN) includes observation, microsurgical resection and radiation therapy. Treatment goals are long-term tumor control, hearing preservation and concurrently low side-effects. Stereotactic radiosurgery (SRS) has evolved as an alternative first-line treatment for small AN. Here we report about the long-term follow-up of a un...
متن کاملOutcome of hearing preservation related to tumor morphologic analysis in acoustic neuromas treated by gamma knife radiosurgery
BACKGROUND Gamma Knife radiosurgery (GKRS) is an important part of the neurosurgical armamentarium in the treatment of acoustic neuromas. However, the treatment outcome related to the morphology of the tumor has not been rigorously studied. In this cohort, we evaluated the morphological features of the tumor in the tumor response and neurological outcomes after GKRS. MATERIAL AND METHODS From...

متن کاملResults of acoustic neuroma radiosurgery: an analysis of 5 years' experience using current methods.
OBJECT The goal of this study was to define tumor control and complications of radiosurgery encountered using current treatment methods for the initial management of patients with unilateral acoustic neuroma. METHODS One hundred ninety patients with previously untreated unilateral acoustic neuromas (vestibular schwannomas) underwent gamma knife radiosurgery between 1992 and 1997. The median f...
