Ahead of Print: Triggering of Auditory Phantoms

Background: Tinnitus is predominantly viewed as the consequence of dysfunctional hyperactivity, plastic change or synchronized oscillations in the central auditory system. An alternative to the current auditory-centric view of auditory phantom perception is the basal ganglia-centric view. Recent electrical stimulation experiments in area LC, a locus of the caudate nucleus positioned at its anterior body, has shown loudness modulation of existing tinnitus percepts.

Objective: To demonstrate auditory phantoms are gated by the dorsal striatum.

Methods: Electrical stimulation in area LC through a DBS lead was performed in 6 interactive adult subjects (3 with and 3 without chronic tinnitus) undergoing surgery to treat movement disorders. Tinnitus loudness was rated on a 0 to 10 scale, sound quality was described and localization was referenced to one or both ears.

Ahead of Print: The Impact of Tinnitus and Vertigo on Patient-Perceived Quality of Life After Cerebellopontine Angle Surgery

Full article access for Neurosurgery subscribers.

Grauvogel, Juergen MD; Kaminsky, Jan MD; Rosahl, Steffen K. MD

BACKGROUND: Quality of life (QOL) has come into focus after treatment for cerebellopontine angle (CPA) lesions.

OBJECTIVE: This study compared subjective (tinnitus, vertigo) and objective (hearing loss, facial palsy) results of CPA surgery with patient-perceived impairment of QOL.

METHODS: A retrospective analysis of a consecutive series of 48 patients operated on for either a vestibular schwannoma or a meningioma in the CPA was performed. Patient’s subjective impairment of QOL by tinnitus, vertigo, hearing loss, and facial nerve palsy was assessed by a visual analog scale (VAS). Objective facial nerve and hearing function were determined using House-Brackmann and Gardner-Robertson classification systems, respectively.

Video: Microvascular Decompression for Atypical Hemifacial Spasm

This is pre- and postoperative video of a patient who underwent successful microvascular decompression for atypical hemifacial spasm. Surgical findings and technique are also shown.

This information has been taken from Microvascular decompression in patient with atypical features of hemifacial spasm secondary to compression by a tortuous vertebral-basilar system, a manuscript to be published in the June 2010 issue of Neurosurgery, submitted by corresponding author Jason Matthew Schwalb, MD, of the Department of Neurological Surgery, University of Rochester School of Medicine and Dentistry.
