OBJECTIVE To update a 15-year-old study of 800 postlinguistically deaf adult patients showing how duration of severe to profound hearing loss, age at cochlear implantation (CI), age at onset of severe to profound hearing loss, etiology and CI experience affected CI outcome. STUDY DESIGN Retrospective multicenter study. METHODS Data from 2251 adult(More)
After more than 25 years of clinical experience, the BAHA (bone-anchored hearing aid) system is a well-established treatment for hearing-impaired patients with conductive or mixed hearing loss. Owing to its success, the use of the BAHA system has spread and the indications for application have gradually become broader. New indications, as well as clinical(More)
OBJECTIVE This study was designed to investigate the perceptual benefits and potential risks of implanting the Nucleus(R) multichannel auditory brainstem implant. DESIGN Between September 1992 and October 1997 a total of 27 subjects received a Nucleus 20- or 21-channel Auditory Brainstem Implant (ABI). All subjects involved in the trial had bilateral(More)
The authors report the CT and MR findings of a rare benign primary choroid plexus papilloma developed in the CPA with invasion of the neighboring structures, apparently the first description of such a case. Differential diagnosis with other CPA tumors is discussed. Papillomas should be considered among the vascular, calcified enhancing masses of the CPA(More)
The cochlear implant (CI), by enabling oral communication in severely to profoundly deaf subjects, is one of the major medical advances over the last fifty years. Despite the globally very satisfactory results, individual outcomes vary considerably. The objective of this review is to describe the various factors influencing the results of CI rehabilitation(More)
The electrochemical composition of endolymph (EL) of two adjacent cochlear turns was studied in anesthetized rats. Differences in [K]EL, [Cl]EL, and endocochlear potential (EP) were found between the basal turn (165.6 +/- 3.0 mM, n = 14; 144.6 +/- 2.1 mM, n = 14;96.6 +/- 1.9 mV, n = 5, respectively) and the middle turn (155.7 +/- 2.5 mM, n = 15; 133.2 +/-(More)
The aim of this review is to provide clinicians with a picture of the mechanisms by which: histamine and histaminergic agonists act on the vestibular system both peripherally and centrally; and histaminergic agonists and antagonists interfere with the recovery process after peripheral vestibular lesion. We have focused on betahistine, a structural analogue(More)
OBJECTIVE To assess the conservation of residual hearing in recipients of the Nucleus 24 Contour Advance cochlear implant (CI) and the benefits of combined electrical and acoustic stimulation. STUDY DESIGN Prospective multicenter study. SETTING CI clinics in Western Europe. PATIENTS Adult candidates for conventional cochlear implantation with a(More)
OBJECTIVE The Vibrant Soundbridge (VBS; Symphonix Devices, Inc., San Jose, CA, U.S.A.) is an active, semi-implantable, middle ear hearing device that directly drives the ossicular chain and is used in the treatment of patients with mild to severe sensorineural hearing loss. The benefits of the VBS and the effects of surgery were examined and compared with(More)
BACKGROUND A consensus conference recommended empirical antibiotic therapy for all patients with postoperative meningitis and treatment withdrawal after 48 or 72 h if cerebrospinal fluid culture results are negative. However, this approach is not universally accepted and has not been assessed in clinical trials. METHODS We performed a cohort study of all(More)
