OBJECTIVES To report on cases of labyrinthine fistula diagnosed in an ear, nose, and throat department and to study the incidence, location, pre- and postoperative symptoms (hearing loss, tinnitus, vertigo, facial palsy), preoperative diagnostic imaging, and surgical treatment of two types of cholesteatomatous labyrinthine fistulae-the extensive fistula(More)
CONCLUSIONS Hearing may be conserved in adults after implantation with the Nucleus Contour Advance perimodiolar electrode array. The degree of hearing preservation and the maximum insertion depth of the electrode array can vary considerably despite a defined surgical protocol. Residual hearing combined with electrical stimulation in the same ear can provide(More)
Refractory status epilepticus was observed in two patients who underwent vestibular neurectomy. We investigated the relationship with the use of an aluminum containing bone cement during the procedure. Two patients developed focal and thereafter generalized seizures in the late postoperative period of vestibular neurectomy (respectively after 42 and 35(More)
Following our previous experimental studies on the performance of macroporous biphasic calcium phosphate (MBCP) in canine mastoid cavities, we used this material in patients requiring surgical intervention. Twenty-two cases were selected, and in eight specific cases a biopsy specimen was taken. Histologic, ultrastructural, and microanalysis studies were(More)
To investigate the association between genes in the major histocompatibility complex and inner ear disease susceptibility at the DNA level, high-resolution genotyping for HLA class II (HLA-DR, -DQ, -DP) was performed by polymerase chain reaction-sequence-specific oligonucleotide reverse dot blot and polymerase chain reaction-restriction fragment length(More)
We have previously shown that a 30,000 Mr protein extracted from guinea pig inner ear tissue is recognized by autoantibodies present in the serum of patients suffering from autoimmune inner ear disease. This protein was localized in the modiolus and in the organ of Corti. We have now identified this protein by a combination of microsequencing and(More)
Cogan's syndrome is a rare disorder that is characterized by a rapid onset of bilateral severe sensorineural hearing loss associated with vertigo and tinnitus, ocular involvement (most commonly an interstitial keratitis) and variable systemic symptoms. We review our experience with four cases treated in our department. We describe their symptoms, the(More)
Today's indications for cochlear implantation. During the last twenty years, the indications for cochlear implants (CIs) extended significantly due to positive experience with CIs, improved CI technology, and safer surgery. This paper reviews the classical and emerging indications for CIs anno 2007. Providing a postlingually deaf adult with a unilateral CI(More)
This report presents the long-term results 3 years after primary myringoplasties performed with formolized fascia temporalis autografts. The overall closure rate was 87.7% of cases, with improvement in hearing in 67.2% of cases. The best results were achieved with total perforations, and not with partial posterior perforations, contrary to popular opinion.(More)
We report an extremely rare case of metastasic renal cell carcinoma to the temporal bone which presented initially as a jugulotympanic paraganglioma. The clinical and radiological appearances were misleading.Investigations of concomitant high blood pressure revealed a tumour of the right kidney. Biopsy of the mastoid mass was histologically compatible with(More)
