Advanced otosclerosis

Lora Batson, Denise Rizzolo
Otosclerosis is a complex and progressive disease of pathological bone remodeling that affects the otic capsule of the temporal bone, resulting in hearing loss. Although traditional diagnostic methods are still used, improvements in technology and research have paved the way for additional diagnostic techniques and advancements. The traditional treatment of otosclerosis, stapes surgery, is now being augmented or replaced by innovations in hearing aid technology and cochlear implants. Earlier diagnosis of otosclerosis can occur through understanding of the cause, risk factors, and current diagnostic testing...

In this article, we present four patients who underwent cochlear implantation due to far advanced otosclerosis. Preoperative evaluations, intraoperative findings, complications, and postoperative benefits were analyzed. Cochlear implantation is a treatment option providing excellent audiological results for rehabilitation of patients with far advanced otosclerosis. However, facial nerve stimulation after cochlear implantation is observed more frequently in patients with otosclerosis. Also, caution should be paid in patients with otosclerosis in terms of cochlear ossification and inconsistent results...

HYPOTHESIS: Ossification of the cochlea was once considered to be a contraindication for cochlear implantation. Advances in cochlear implant technology and coding strategies have led to developments in different surgical procedures to manage cochlear ossification. The endoscopic technique allows a direct approach to the round window and the cochlea, especially in remodeled labyrinth, allowing a better vision of scala tympani. BACKGROUND: Tertiary referral ENT center...

OBJECTIVE: To verify the efficacy of a powerful active hearing device in a patient different from far-advanced otosclerosis, specifically when the stapes footplate is mobile. PATIENT: A patient with severe-to-profound mixed hearing loss, who was not benefiting from the use of a conventional hearing aid, was selected for an inner ear active implant. This was justified by a bone conductive threshold above 60 dB, which had discouraged any other rehabilitative solutions such as a bone conductive implant, or an active middle ear implant (AMEI)...

Julius Lempert (1891-1968) was one of the most revolutionary and innovative neuro-otologists of the 20th century. He had a remarkable role in advancing the field of otolaryngology to its modern shape and form, especially through his groundbreaking introduction of the fenestration procedure for the treatment of otosclerosis. Although he is highly celebrated by many neuro-otologists for his contributions to our surgical and anatomical understanding of the petrous bone, he is not well known to the neurosurgical community...

The objective of the present study was to evaluate the effectiveness of the surgical treatment of otosclerosis in the subjects of advanced age. The medical histories of 19 patients aged above 65 years (20 ears) presenting with otosclerosis were available for the retrospective analysis. All of them had undergone surgical interventions (a total of 22 ones or 4.49% of the 489 operations performed between 2001 and 2012). The audiometric assessment was made at four wavelengths (0.5, 1, 2, and 4 kHz). Primary surgery (n=18) was preceded by the determination of the high air and bone conductivity thresholds (76...

OBJECTIVE: Implantable hearing aids have become a valid option for the therapy of various forms of hearing loss. The Codacs™ Direct Acoustic Cochlear Implant System is the first vibratory implant available for patients with severe to profound mixed hearing loss (MHL). By directly coupling sound energy into the perilymph, a very high maximum power output (MPO) is achieved over a broad frequency range. Via a conventional stapedotomy, the vibratory energy of the electromagnetic actuator is transferred directly to the perilymph through the oval window...

INTRODUCTION: Several studies support the use of cochlear implants (CI) in far-advanced otosclerosis (FAO). MATERIAL AND METHODS: We compared our results of CI in patients with FAO and unknown origin hearing loss (UOHL) and our incidence of facial electrical stimulation and difficult insertion of the electrode bundle up to 3 to 5 years from surgery. RESULTS: We found 17 patients with CI in FAO and UOHL. FAO patients achieved better results on the pure tone average (PTA) and recognition of monosyllables by GEE test (p=0...

Advances in operative technique, instrumentation, and prosthesis design in otosclerosis surgery continue since Shea performed the first successful surgery. This is the first analysis to specifically compare post-operative hearing outcomes following stapedotomy surgery performed under local versus general anesthesia. Hearing outcomes were further stratified by comparing conventional perforator and Er:YAG laser ablation perforation techniques. Pre- and post-operative audiograms were retrospectively analyzed together with the method of anesthesia and the perforation technique for all patients with otosclerosis who underwent stapedotomy between 1998 and 2007...

The aim of this study was to investigate the efficacy of a direct acoustic cochlear implant (DACI) for speech understanding in noise in patients suffering from severe to profound mixed hearing loss (MHL) due to various etiologies compared to the preoperative best-aided condition. The study was performed at five tertiary referral centers in Europe (Belgium, Germany, Poland and Spain). Nineteen adult subjects with severe to profound MHL due to (advanced) otosclerosis, ear canal fibrosis, chronic otitis media, tympanosclerosis or previous cholesteatoma were implanted with a DACI (Codacs™ Investigational Device) combined with a conventional stapes prosthesis...

HYPOTHESIS: Unintentional electrical stimulation of the facial nerve by cochlear implants occurs when advanced otosclerosis invades the endosteum of both the upper basal turn of the cochlea (UBTC) and the facial nerve canal (FNC) and all the bone between these 2 structures. BACKGROUND: A complication of cochlear implantation is facial nerve stimulation (FNS) known to be more common in otosclerosis. Otosclerotic involvement of the enchondral bone of the otic capsule results in areas of bone resorption, new bone formation, vascular proliferation, and a connective tissue stroma...

OBJECTIVES: To compare hearing outcomes in patients with far advanced otosclerosis (FAO) undergoing cochlear implantation to an age-matched group of controls, to describe the effects of cochlear ossification on hearing, and to review the adverse effects of implantation in patients with FAO. HYPOTHESIS: Hearing performance in patients with FAO after cochlear implantation is comparable to similarly treated postlingually deafened adults without FAO. Ossification or retrofenestral otosclerosis does not predict poor hearing outcomes...

OBJECTIVES/HYPOTHESIS: Postmeningitic basal turn ossification is a challenge for successful cochlear implantation despite the availability of sophisticated implants and advanced drill-out procedures. A less complex concept consisting of a cochleostomy near the apex with retrograde array insertion is evaluated clinically and experimentally with emphasis on imaging of intracochlear array morphology. STUDY DESIGN: Retrospective case-control study. METHODS: Outcome, hearing performance, and radiological findings including three-dimensional (3D) reconstructions were assessed in the long term in eight retrograde implanted ears of seven postmeningitic deaf patients and compared to an etiology- and device-matched control group of 17 basal turn implanted ears of 14 patients...

HYPOTHESIS: Mechanical stimulation through a cochlear third window into the scala tympani in a chinchilla model with normal and fixed stapes can generate cochlear responses equivalent to acoustic stimuli. BACKGROUND: Cochlear stimulation via the round window (RW) using active middle ear implants (AMEIs) can produce physiologic responses similar to acoustic stimulation including in a model of stapes fixation. However, pathologic conditions, such as advanced otosclerosis, can preclude delivery of sound energy to the cochlea through the oval window and/or the RW...
