Incidence of Developing Contralateral Ménière's Disease in Patients Undergoing Transmastoid Labyrinthectomy for Unilateral Ménière's Disease.

Objectives: To analyze the incidence of developing contralateral Ménière's disease (MD) in patients who undergo labyrinthectomy for vestibular dysfunction in unilateral MD.

Study Design: Retrospective chart review.

Participants And Methods: Adult patients with a diagnosis of MD who underwent surgical labyrinthectomy with minimum follow-up of 12 months were included.

Hydroxyapatite cement cranioplasty following translabyrinthine approach: Long-term study of 369 cases.

Objective: To report the authors' experience with hydroxyapatite cement (HAC) cranioplasty and analyze the material's long-term safety and efficacy in repairing translabyrinthine skull-base defects by examining adverse events, specifically cerebrospinal fluid (CSF) leaks and surgical site infections.

Study Design: Retrospective case-control study (primary study arm); prospective cross-sectional study of patients not examined within the last 5 years (secondary arm).

Setting: tertiary-care neurotology private practice and academic practice (two centers).

Is MRI Equal to CT in the Evaluation of Thin and Dehiscent Superior Semicircular Canals?

Objective: Can magnetic resonance imaging (MRI) diagnose abnormally thin and dehiscent superior semicircular canals (SSCs) that traditionally rely on evaluation by computed tomography (CT) imaging?

Study Design: Retrospective clinical study.

Setting: Tertiary referral center.

Patients: Adults who underwent both MRI and CT of the temporal bones over the past 3 years.

Does electrocautery damage cochlear implants?

Objectives: 1) Evaluate the effects of monopolar cautery on cochlear implant devices. 2) Determine whether voltage fluctuations within the cochlear implant adversely affect the cochlear implant devices

Study Design: Two Med-El cochlear implants modified to record voltage difference from the apical and proximal electrodes were implanted into an unembalmed, fresh cadaver. Cautery was applied to the ipsilateral pectoralis major muscle and ipsilateral temporalis muscle at bipolar, monopolar coagulation, and monopolar cut settings of 50 W.

The relationship of age and radiographic incidence of superior semicircular canal dehiscence in pediatric patients.

Objective: To determine if age affects radiographic incidence of superior semicircular canal dehiscence (SSCD) in pediatric patients.

Study Design: Retrospective case review.

Setting: Tertiary children's hospital.

Cochlear trajectory in pediatric patients.

Objectives/hypothesis: As cochlear implantation increases, surgeons are noting possible anatomical differences in pediatric population. Outcome objectives were to study pediatric temporal bone anatomy using high-resolution temporal bone imaging, and analyze the anatomical differences in group 1 (<12 months) versus group 2 (1-4 years) versus group 3 (5-10 years) versus group 4 (10-18 years).

Study Design: Retrospective chart and radiologic review.
