Our objective is to prospectively report very early complications and outcomes of cerebellopontine angle (CPA) surgery. Between January and August 2007, 72 patients were operated on by different transpetrosal approaches in a tertiary referral center. During preoperative assessment, facial nerve function (House-Brackmann grading system), the presence of(More)
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)
The objective of this study was to evaluate the benefit of cochlear implantation in adults aged 60 years and over. Twenty-eight patients, older than 60 years and with profound bilateral sensorineural hearing loss, received a cochlear implant between 1991 and 2001. The mean age was 66 years and the median follow-up was 22.5 months. Speech perception scores(More)
CONCLUSION Residual hearing could be preserved with various arrays ranging from 16 to 18 mm in insertion length and 0.25 to 0.5 mm tip diameter. Whether array insertion is performed through a cochleostomy or a round window, tip diameter is an essential criterion for the array design to improve hearing preservation results. OBJECTIVES The goal of this(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)
Paragangliomas, or glomus tumors, are highly vascular benign tumors of the head and neck. Clinical symptoms are essentially progressive and neurological, involving infiltration of the regional cranial nerves. The usual treatment is surgery, which itself is a challenge because of the close proximity of vital structures and the considerable blood loss.(More)
A case of rhabdomyosarcoma of the tongue in an adult male is reported. The diagnosis of this rare lesion is difficult and should be considered in every growing mass of the head and neck region. It is based on the pathologic examination of tissue samples guided by immunohistological methods. In this case the examination revealed an embryonal type. The(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)
