HYPOTHESIS: Simulated otitis media with effusion reduces intracochlear pressures comparable to umbo velocity. BACKGROUND: Otitis media with effusion is a common cause of temporary hearing loss, particularly in children, producing deficits of 30 to 40 dB. Previous studies measured the effects of simulated effusion on ossicular mechanics; however, no studies have measured cochlear stimulation directly. Here, we compare pressures in the scala vestibuli and tympani to umbo velocity, before and after induction of simulated effusion in cadaveric human specimens...

BACKGROUND: Cholesteatoma is widely considered to be more aggressive in children than adults, yet few studies have directly compared the operative findings and surgical outcomes between these two groups. This study aimed to assess differences between childhood and adult cholesteatoma. METHODS: The operative caseload of a single consultant surgeon was reviewed between January 2006 and May 2017 using the online Common Otology Audit database. Extracted data were categorised according to patient age (children, aged below 16 years, and adults, aged 16 years or over) and compared...

OBJECTIVE: Ossicular chain reconstruction (OCR) is a surgical method used to repair conductive hearing loss. In children, up to 40% of OCRs will require revisions. In this study, our aims were to validate improvement in hearing outcomes following revision OCR and identify prognostic factors for successful revision OCRs. DESIGN: Retrospective review at the Children's Hospital of Pittsburgh from 2003 to 2014. SETTING: Tertiary referral center...

OBJECTIVE: This study was aimed to investigate whether wideband tympanometry (WBT) can distinguish among various kinds of conductive hearing loss and provide additional information. METHODS: We recruited normal subjects and patients with conductive hearing loss due to the following reasons: tympanic membrane perforation only, ossicular chain problem only, and one or other of those conditions combined with mastoid problems. Wideband absorbance at ambient pressure, peak pressure, resonance frequency, and averaged tympanogram data were measured by WBT and compared between the normal, tympanic membrane perforation only, ossicular chain problem only, and combined with mastoid problems groups...

INTRODUCTION: Injuries to the peripheral auditory system are among the most common results of high intensity impulsive acoustic exposure. Prior studies of high intensity sound transmission by the ossicular chain have relied upon measurements in animal models, measurements at more moderate sound levels (i.e. < 130 dB SPL), and/or measured responses to steady-state noise. Here, we directly measure intracochlear pressure in human cadaveric temporal bones, with fiber optic pressure sensors placed in scala vestibuli (SV) and tympani (ST), during exposure to shock waves with peak positive pressures between ∼7 and 83 kPa...

Objective: To analyze the clinical effect of 54 cases with chronic otitis media prepared for staging tympanoplasty and 19 cases finished staging ossicular reconstruction surgery, evaluate the advantages of different surgery technique. Method: Fifty-four cases with chronic otitis media were planned for staging tympanoplasty surgery and had been received the first stage surgery. Silicagel plates were placed in the tympanic cavity in order to prevent adhesions. Among them, 19 cases had received the second stage ossicular reconstruction, including 10 cases with TORPs and 9 cases with PORPs...

Objective: To observe the clinical effect on the treatment of intractable tympanitis with reconstruction of external auditory canal wall. Method: Five cases underwent radical removel of residual lesion and reconsruction of external auditory posterior canal wall using hydroxyapatite ceramic wall with transferred pedicle temporalis fascia covering on it were analyzed. The implement of ossicular chain reconstruction depends on the probing for tympanic cavity intraoperatively. Periodic review were conducted in the 1st, 3rd, 6th, 12th month after surgery...

Preoperative routine hearing tests and temporal bone CT examination. Completely remove of lesions at the same time and as much as possible to protect the integrity of the tympanic wall mucosa during operation...

HYPOTHESIS: A total ossicular replacement prosthesis (TORP) with a silicone coated ball and socket joint (BSJ) is able to compensate pressure changes and therefore provide better sound transmission compared with rigid prostheses. BACKGROUND: Dislocation and extrusion are known complications after TORP reconstruction, leading to revisions and recurrent hearing loss. Poor aeration of the middle ear, scar tension, and static pressure variations in conjunction with rigid prosthesis design causes high tension at the implant coupling points...

Middle ear hearing reconstruction is unpredictable. Difficulties arise because of host factors, such as ventilation or scarring, surgical technique factors, such as prosthesis placement and stabilization, and design and mechanical factors influencing the properties of the prosthesis. Often there is a balancing act between choosing optimal stability, and maximizing the mechanical vibrations of the prosthesis. We review our and other investigators' work, in design and ideal placement of middle ear prostheses...

Objectives: The classical overlay tympanoplasty is technically difficult with some disadvantages and thus less popular. However, it is particularly useful for large, anterior perforations. In this study, we describe the technique of a modified overlay graft in the tympanoplasty coined as the swing-door overlay tympanoplasty and report its outcomes. Methods: Retrospective review of patients undergoing the swing-door overlay tympanoplasty at a tertiary referral center between 2003 and 2016 was performed...

OBJECTIVE: The aim of this study was to evaluate the hearing outcomes and complications of stapedotomy in which the stapes superstructure was preserved (Takagi's stapedotomy). In this surgical approach, the lenticular process of the incus rather is removed, than the superstructure of the stapes. METHODS: A single-center retrospective observational study was performed. We included all patients having Takagi's stapedotomy for otosclerosis between January 2005 and April 2016...

OBJECTIVE: We report our retrospective study of the recovery rate of auditory ossicles preserved facial nerve decompression surgery via the transmastoid approach in cases of both an electroneurography score of < 10% and a Yanagihara score of ≤8 in Bell's palsy and Ramsay Hunt syndrome. MATERIALS AND METHODS: We retrospectively reviewed 47 patients who we were able to follow-up for more than 6 months following the onset of palsy. The recovery rate was defined by the Japan Society for Facial Nerve Research or the Yanagihara score...

In case of cholesteatoma with intact ossicular chain, the primary aims of surgery are complete removal of the cholesteatoma matrix and reconstruction of a dry and safe middle ear; if possible, ossicular chain continuity and therefore the preoperative hearing must be preserved. The aim of this retrospective study is to present the experience of the U.O.C. Otorinolaringoiatria Universitaria of University of Bari "Aldo Moro" in treatment of intact ossicular chain cholesteatoma with Bondy modified radical mastoidectomy (BMRM) and canal wall up tympanoplasty (CWUT)...

Subtotal petrosectomy may be performed for refractory chronic middle ear diseases, such as massive cholesteatoma or recurrent otitis media. It involves permanent obliteration of the operative cavity, thus precluding the chance to restore conductive hearing via traditional inertial ossicular prostheses. The Vibrant Soundbridge (VSB) is an alternative option for hearing rehabilitation. Vibrant energy is delivered into the inner ear via a floating mass transducer (FMT), which can be coupled with any part of the middle ear acoustic transmission structure...
