Detection of CMV DNA in the perilymph of a 6-year-old boy with congenital cytomegalovirus infection

June 14, 2016  |  Ina Foulon, MD; Oriane Soetens, PhD; Leen Vleurinck, MA; Frans Gordts, PhD; Astrid Leus, MD; Anne Naessens, PhD

Abstract

We present the case of a 6-year-old boy who received a cochlear implant for profound sensorineural hearing loss after being born with cytomegalovirus (CMV) infection. Even after 6 years, CMV DNA was still found in the perilymph of the cochlea. Our case shows that CMV DNA can be...

The effects of round window membrane injury and the use of a model electrode application on hearing in rats

March 16, 2016  |  Murat Koc, MD; Abdullah Dalgic, MD; Mehmet Ziya Ozuer, MD

Abstract

We conducted an animal experiment to investigate the effects of mechanical trauma to the round window with the placement of a model electrode inserted into the scala tympani on the cochlear reserve, and to determine the efficacy of topical steroids in preventing hearing loss in...

Streamlined bilateral otologic surgery: How I do it

March 2, 2015  |  Tara E. Brennan, MD; Miriam I. Redleaf, MD

Abstract

Bilateral simultaneous otologic surgery is being performed more commonly among otologists. The benefits of performing bilateral simultaneous cochlear implants in the pediatric population, in particular, have become increasingly recognized as the safety and efficacy of this...

Cochlear implantation leading to successful stapedectomy in the contralateral only-hearing ear

March 2, 2015  |  Samantha J. Mikals, MD; Gerald I. Schuchman, PhD; Joshua G.W. Bernstein, PhD; Arnaldo L. Rivera, MD

Abstract

Cochlear implants have recently begun to be offered to patients with single-sided deafness (SSD). Implantation in these patients has led to good results in suppressing ipsilateral tinnitus and in providing audiologic benefits in terms of speech perception in noise and...

Effect of low-level laser therapy in the treatment of cochlear tinnitus: A double-blind, placebo-controlled study

January 19, 2015  |  Mahboobeh Adami Dehkordi, MD; Sasan Einolghozati, MD; Seyyed Mohsen Ghasemi, PhD; Samaneh Abolbashari, MD; Mojtaba Meshkat, MSc; Hadi Behzad, MSc

Abstract

Many treatments for chronic tinnitus have been attempted, but the condition remains difficult to cure, especially in the case of cochlear tinnitus. We conducted a prospective, double-blind, placebo-controlled study to assess the effect of low-dose laser therapy on chronic...

Cochlear fistula in a noncholesteatomatous ear

September 18, 2014  |  Yoav Hahn, MD; Dennis I. Bojrab, MD

Abstract

Bony destruction of the labyrinth is usually associated with long-standing cholesteatomatous otitis media. The promontory is not a common site for bone resorption because (1) it is not an area that is involved in accumulation of cholesteatoma perimatrix substances, (2) it is...

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

Abstract

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

Abstract

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

Abstract

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

Abstract

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...
