Immunization guidelines for cochlear implant recipients

October 24, 2013  |  Barry E. Hirsch, MD

Patients who have a cochlear implant are considered to be at a higher risk of developing meningitis following otitis media. Whether this occurs along the electrode going from the middle ear into the cochlea or through a blood-borne pathway is unclear.

Subcutaneous emphysema and pneumolabyrinth plus pneumocephalus as complications of middle ear implant and cochlear implant surgery

July 22, 2013  |  Brian J. McKinnon, MD, MBA; Tamara Watts, MD, PhD


We conducted a retrospective case review at a tertiary academic medical center for the complications of pneumolabyrinth with pneumocephalus and subcutaneous emphysema after surgery for middle ear and cochlear implants. Charts of 76 cochlear implant and 2 middle ear implant...

A purely intracanalicular cochlear schwannoma presenting with progressive hearing loss

October 27, 2011  |  Hüseyin Işıldak, MD, Metin Ibrahimov, MD, Mehmet Yilmaz, MD, Ozgun Enver, MD, and Sait Albayram, MD


Schwannomas arising from the cochlear nerve and confined to the internal auditory canal are rare. Clinically, a cochlear schwannoma can cause a progressive hearing loss. We report the case of a 56-year-old woman with a cochlear schwannoma that manifested as a slowly progressive...

Cochlear implant fixation using resorbable mesh

July 14, 2011  |  Larry Lundy, MD and Selmin Karatayli-Ozgursoy, MD


In this article we describe a new method of cochlear implant receiver-stimulator fixation using a resorbable poly (D,L) lactic acid mesh. We conducted a retrospective case review at a tertiary referral center; 10 pediatric and 4 adult patients had undergone cochlear...

Clinical significance of a hearing and imaging workup in a child with cochlear nerve aplasia and a normal internal auditory canal

December 1, 2009  |  Fernando Ribeiro, MD, Liciere Marotta, MD, and Claudia A. Eckley, MD


Modern magnetic resonance imaging has significantly improved the diagnosis of cochlear nerve deficiencies. A careful assessment of all clinical, imaging, and auditory data is of utmost importance in such cases in order to properly establish the site of the abnormality. We...

Transmastoid labyrinthotomy approach for cochlear implantation in a common cavity malformation: A case report

June 1, 2008  |  Masoud Motasaddi Zarandy, MD


The standard transmastoid facial recess approach has become the popular technique for cochlear implantation. Although this approach has been used for implantation in patients with common cavity malformations, in patients with this anomaly and severe abnormalities of the middle...

Hearing loss and cerebrospinal fluid pressure: Case report and review of the literature

March 1, 2008  |  Matthew S. Pogodzinski, MD, Jon K. Shallop, PhD, Juraj Sprung, MD, PhD, Toby N. Weingarten, MD, Gilbert Y. Wong, MD, and Thomas J. McDonald, MD


A decrease in cerebrospinal fluid pressure may result in an endolymphatic hydrops through a patent cochlear aqueduct or through the fundus of the internal auditory canal. This hydrops typically leads to low-frequency sensorineural hearing loss. We describe the case of a man who...
