Endolymphatic sac tumors: clinical outcome and management in a series of 9 cases.

Objectives: Endolymphatic sac tumors (ELSTs) are rare adenomatous tumors arising in the petrous bone, either spontaneously (isolated) or in association with von Hippel-Lindau (VHL) disease. For 9 patients, this study describes the typical features and management of ELST and the clinical outcome of treatment. Similarities and differences are identified for ELST in isolation and in association with VHL disease.

Cochlear implantation in postlingually hearing-impaired adults: choosing the most appropriate ear.

Choice of the most appropriate ear for CI in postlingually hearing-impaired adults is becoming more relevant as more patients are considered eligible for intervention. The aim of this study is to review factors that influence this choice and to formulate a flowchart. An extensive Medline search was performed.

Cochlear implantation in patients with acute or chronic middle ear infectious disease: a review of the literature.

Although in the past cochlear implantation was considered contraindicated in patients with acute (AOM) or chronic suppurative otitis media (CSOM) with or without middle ear cholesteatoma, recent developments now make it possible to perform cochlear implantation in these patients. Various procedures are available to make the ears of patients with either acute or CSOM suitable for cochlear implantation and to minimize the risk of recurrence of the disease, device extrusion, or intracranial complications. This review discusses these different approaches for optimizing implant survival and preventing complications related to otitis media.

Audiological performance after cochlear implantation: a 2-year follow-up in children with inner ear malformations.

Conclusions: Open-set speech perception in children with an inner ear malformation is equal to that of other congenitally deaf children after an average of 2 years follow-up.

Objective: To analyze audiological performance after cochlear implantation in a sample of children with radiographically detectable malformations of the inner ear compared to performance in prelingually deafened children at large.

Materials And Methods: Nine children with osseous inner ear malformations were compared to 22 congenitally deaf children, all of whom underwent cochlear implantation.

Cochlear implantation in obstructed cochleas: the effect of the degree of obstruction on the number of activated electrodes and the amount of postoperative speech perception.

Objective: With cochlear implantation, insertion of the electrodes can be hampered by cochlear obstructions. The aim of this study was to investigate the effects of these obstructions on the number of activated electrodes and postoperative speech perception.

Study Design And Setting: Retrospective analysis of the operation reports and CT-scans of patients who underwent cochlear implantation, at the Department of Otorhinolaryngology of the University Medical Center of Utrecht (n = 295).
