Validation of the Penn Acoustic Neuroma Quality of Life (PANQOL) Scale for Hindi-Speaking Patients Recently Diagnosed with Vestibular Schwannoma.

Background: The Penn Acoustic Neuroma Quality-of-Life (PANQOL) scale is a disease specific quality-of-life instrument for vestibular schwannoma, developed in English and subsequently validated in four major languages of the world. No such validated version of PANQOL exists for Hindi-speaking population.

Objective: To translate and examine the validity of the PANQOL scale in a sample of Hindi-speaking patients recently diagnosed with vestibular schwannoma.

Quality of life in patients of unilateral vestibular schwannoma treated with microsurgery: A South-Asian tertiary care Hospital experience.

Majority of the published literature on the impact of microsurgery over quality-of-life (QOL) in vestibular schwannoma (VS) patients is retrospective in nature, with variable results, and there has been very little contribution from South-Asia. The authors designed this study to investigate the role of microsurgery in QOL alterations in VS patients, and to compare obtained QOL scores with that of control population. Between February 2017 and March 2018, a prospective/retrospective study was done at our institute.

Meningioma in a patient with Werner syndrome.

Werner syndrome (WS), also known as adult progeria, is extremely rare, with about 1300 known cases in the world, with over 1000 of these in Japan. It occurs due to loss of function mutations in the WRN gene located on chromosome 8p12. WS is characterized by premature aging and increased risk of neoplasms, with meningiomas being the commonest intracranial tumor.

Microsurgery of Vestibular Schwannoma Post-radiosurgery.

Objectives: Microsurgery of vestibular schwannoma (VS) after radiosurgery is not common. In this study, we analyze nerve functional outcomes and technical challenges associated with the microsurgery following radiosurgery of VS.

Materials And Methods: Sixteen patients underwent microsurgery at an average of 37 months (range 3-96 months) after radiosurgery.

Correlation of Preoperative Cranial Nerve Diffusion Tensor Tractography with Intraoperative Findings in Surgery of Cerebellopontine Angle Tumors.

Objective: Imaging to visualize nerves around tumors preoperatively could help the surgeon to plan the surgery and excise the tumor with preservation or improvement in patients' quality of life. In the present prospective study, we attempted to correlate the preoperative cranial nerves (i.e.

Newer advances in lesional surgery for movement disorders.

An analysis of the existing literature on lesioning for movement disorders was undertaken to review lesion therapy and its advances. Advances in imaging technology and electrophysiological techniques used for localization of brain structures and its functions, such as microelectrode recordings and macrostimulation, have greatly improved the ability to accurately identify the target nuclei such as the ventrointermediate nucleus (Vim), globus pallidus interna (GPi) and subthalamic nucleus (STN). Many important changes are happening in the understanding of lesion making.

Application of fluorescein sodium videoangiography in surgery for spinal arteriovenous malformation.

We present our recent experience with fluorescein sodium videoangiography (FLVA) in the intra-operative evaluation of a patient with conus medullaris arteriovenous malformation (AVM). To our knowledge this is the first report in the literature of use of FLVA in the surgery of spinal AVM. Intra-operative FLVA was done to identify an early filling vessel and to obliterate the site of fistulous connection.

Anterior petrosal approach for brainstem cavernoma.

Brainstem cavernomas (BC) comprise about 5-18% of intracranial vascular malformations. The annual hemorrhage rate varies depending on the study design ranging from as low as 0.25% per patient-year in a retrospective study[2] to 1.
