Ossicular implants made from metallic materials may be acceptable or pose hazards for patients referred for magnetic resonance imaging (MRI) examinations, depending on the outcome of proper MRI testing procedures. ⋯ The results of this investigation demonstrated that it would be acceptable (i.e., "MR conditional" using current terminology) for patients with these ossicular implants to undergo MRI examinations at 3 T or less. In consideration of the materials and dimensions of the implants that underwent testing, these findings pertain to many other similar ossicular implants from the same manufacturer.

It is possible to implant a stimulating electrode array in the semicircular canals without damaging rotational sensitivity or hearing. The electrodes will evoke robust and precisely controlled eye movements. ⋯ It is possible to implant the vestibular system with prosthetic stimulating electrodes without loss of rotational sensitivity or hearing. Because electrically evoked eye movements can be reliably obtained with the assistance of intraoperative electrophysiology, it is appropriate to consider treatment of a variety of vestibular disorders using prosthetic electrical stimulation. Based on these findings, and others, a feasibility study for the treatment of human subjects with disabling Ménière's disease has begun.

To report our approach to the surgical management of vestibular schwannomas (VSs) and hearing rehabilitation in neurofibromatosis Type 2 (NF2). ⋯ By following a policy of treating VS in NF2 patients where tumor growth is observed, complete tumor resection can be achieved through a translabyrinthine approach while achieving comparable facial nerve outcomes to published series. We advocate proactive hearing rehabilitation in all patients with timely assessment for auditory implantation to maintain quality of life.

Comparative Study
Prevalence and hospital resource utilization in tympanoplasty and revision tympanoplasty: a population-based comparative study.
To compare trends, risk factors, prevalence rates, and hospital resource utilization between tympanoplasty and revision tympanoplasty. ⋯ High-volume hospitals and surgeons obtained the largest improvements in tympanoplasty outcomes, particularly in LOS and hospital treatment costs. Health care providers and patients should recognize that hospital resource utilization may depend on hospital attributes as well as patient attributes.

Despite complaints of dizziness, some patients with unilateral compensated vestibular weakness show normal results on Sensory Organization Test (SOT), which is being widely used for the evaluation of vestibular function compensation. The head shake-sensory organization test (HS-SOT) has been suggested to increase the sensitivity of SOT. In HS-SOT, the patient is required to shake head under Conditions 2 and 5 of traditional SOT. However, the sensitivity of HS-SOT remains unelucidated in patients with vestibular neuritis. The aim of this study was to determine the sensitivity of HS-SOT and SOT and compare them with the Dizziness Handicap Inventory (DHI) in detecting balance problems in patients with vestibular neuritis complaining of dizziness. ⋯ HS-SOT was more sensitive than SOT during the compensation of vestibular neuritis. Specifically, during the compensation of vestibular neuritis, HS-SOT Condition 5 was more correlated with DHI than HS-SOT Condition 2. The results suggest that HS-SOT provides more useful measures for the evaluation of vestibular compensation in vestibular neuritis.
