Cochlear implantation using posterior suprameatal approach

August 18, 2018  |  Gabor Repassy, MD, PhD; Marianna Kustel, MD, PhD; Magdolna Szonyi, MD, PhD; Adam Enreiter, MSc; Ede Birtalan, MD, PhD; Laszlo Tamas, MD, PhD

Abstract

When cochlear implantation was first introduced, the mastoidectomy and posterior tympanotomy approach was the most frequently used technique to gain access to the middle ear and the cochlea. Since 2000, several authors have routinely used a non-mastoidectomy nonposterior...

Assessment of discrimination ability in ipsilateral and contralateral ears with a unilateral bone-anchored hearing system

August 24, 2017  |  Bahtiyar Celikgun, MSc; M. Tayyar Kalcioglu, MD

Abstract

This study aimed to determine the speech discriminatory ability of the contralateral ear of users of a unilateral bone-anchored hearing system (BAHS). The Oticon Medical Ponto Pro/Ponto Pro Power device brand was used for all patients. Five BAHS users (3 men, 2 women)...

The Sophono bone-conduction system: Surgical, audiologic, and quality-of-life outcomes

July 18, 2017  |  Timothy Mclean, MBBS; Irumee Pai, FRCS; Andrew Philipatos, BSc; Michael Gordon, FRACS

Abstract

We prospectively evaluated the surgical, audiologic, and quality-of-life outcomes in 5 patients-2 men and 3 women, aged 22 to 64 years (mean: 41.8)-who were implanted with the Sophono Alpha 2 MPO Processor. The indications for implantation of this bone-conduction device...

Cochlear implant electrode array exposure: A delayed complication

July 18, 2017  |  Christina Mishu, AuD; David A. Klodd, PhD; Miriam Redleaf, MD, FACS

Abstract

Exposure of the cochlear implant electrode array as a late complication has been reported rarely in the literature. A retrospective analysis revealed 4 patients presenting with exposure of their cochlear implant electrode arrays from 2 to 17 years after implantation. Data...

Speech perception and auditory performance following cochlear implantation in elderly Koreans

March 24, 2017  |  Sungsu Lee, MD, PhD; Hyong-Joo Park, MD; Hyong-Ho Cho, MD, PhD; Yong-Beom Cho, MD, PhD

Abstract

The benefits of cochlear implantation (CI) in the elderly remain debatable in terms of sound and speech perception. Moreover, the results of CI may be affected by the intensity and pitch of spoken language. We conducted a retrospective study to evaluate surgical and...

Primary solitary intralabyrinthine schwannoma: A report of 7 cases and a review of the literature

December 7, 2016  |  Avi Shupak, MD; Yehuda Holdstein, MD; Margalit Kaminer, MSc; Itzhak Braverman, MD

Abstract

Intralabyrinthine schwannomas (ILSs) are uncommon benign tumors that originate in the Schwann cell sheath of the intralabyrinthine distal branches of the vestibulocochlear nerve. They have no initial involvement in the internal auditory canal, although that might develop later...

Are routine preoperative CT scans necessary in adult cochlear implantation? Implications for the allocation of resources in cochlear implant programs

August 21, 2016  |  Bruno Kenway, MRCS, DO-HNS; Petros V. Vlastarakos, MD, MSc, PhD; Anand V. Kasbekar, MRCS, DO-HNS; Patrick R. Axon, MD, FRCS(ORL-HNS); Neil Donnelly, MSc, FRCS(ORL-HNS)

Abstract

Our aim was to critically assess the influence of preoperative computed tomography (CT) scans on implantation decisions for adult cochlear implant candidates. The working hypothesis was that these routine scans might not provide critical additional information in most adult...

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...
