Electrical Promontory Stimulation in Patients With Intact Cochlear Nerve and Anacusis Following Acoustic Neuroma Surgery

Facial Nerve Stimulation in Cochlear Implant Patients

Increased Parasympathetic Nerve Tone in Tinnitus Patients Following Electrical Promontory Stimulation.

Cutaneous digital blood flow (CDBF) during electrical promontory stimulation was measured by laser Doppler flowmetry in 46 tinnitus patients. In patients with tinnitus suppression. CDBF was increased. In contrast, patients in whom treatment did not suppress tinnitus experienced no change in digital blood flow. The cutaneous digital blood flow of patients who experienced slight relief did not di...

Safe electrical stimulation of the cochlear nerve at the promontory during functional magnetic resonance imaging.

The purpose of this study was to evaluate possibilities and technical risks for combining intended electrical stimulation of the cochlear nerve and functional magnetic resonance imaging (fMRI). Theoretical considerations and experiments indicate that fMRI can be performed safely during electrical stimulation. A nerve stimulator was developed with minimized length of electrical conductors, curre...

[Complications and sequelae in acoustic neuroma surgery].

OBJECTIVE To evaluate the complications and sequelae of acoustic neuroma surgery, according to tumour size. PATIENTS AND METHOD A retrospective analysis of 120 patients who underwent microsurgical resection of vestibular schwannomas between November 1994 and September 2006 was undertaken. Tumour size, extent of removal, preservation of facial and cochlear nerves, complications, and sequelae w...
