OBJECTIVE To evaluate speech performance, in quiet and noise, and localization ability in adult patients who had undergone bilateral and simultaneous implantation. STUDY DESIGN Prospective multi-center study. METHODS Twenty-seven adult patients with profound or total hearing loss were bilaterally implanted in a single-stage procedure, and simultaneously(More)
Surgical management of bilateral vestibular schwannomas (VS) in neurofibromatosis type 2 (NF2) is often difficult, especially when both tumors threaten the brainstem. When the largest tumor has been removed, the management of the contralateral VS may become puzzling. To give new insights into the growth pattern of these tumors and to determine the best time(More)
OBJECTIVE To describe and analyze three unusual cases of Langerhans' cell histiocytosis of the temporal bone in adults. STUDY DESIGN Retrospective case review. SETTING A tertiary referral center. PATIENTS Three adult patients with progressive sensorineural or mixed hearing loss, vertigo, and tinnitus as presenting symptoms of Langerhans' cell(More)
Meningiomas of the posterior fossa represent a heterogeneous group of tumors regarding difficulty of resection and functional outcome. The aim of this review was to focus on tumors located mainly on the posterior surface of the petrous bone and threatening hearing and facial functions. An anatomical classification was used to evaluate surgical outcome(More)
OBJECTIVE The aim of this study was to evaluate the potential improvements of speech perception and sound quality provided by a multiband single channel noise-reduction algorithm based on the modified Wiener-filter adapted to cochlear implant sound processing. DESIGN This study was a longitudinal trial with a repeated-measures design. Outcome measures(More)
Technological advances in the domain of digital signal processing adapted to cochlear implants (CI) are partially responsible for the ever-improving outcomes observed with this neural prosthesis. The goal of the present study was to evaluate audiometric outcomes with a new signal processing strategy implemented in Oticon Medical-Neurelec cochlear implant(More)
