OBJECTIVE: The efficiency of vibroplasty (coupler-floating mass transducer [FMT] assembly) can be monitored by direct stimulation of the inner ear through the active middle-ear implant system and comparison of the vibroplasty in vivo threshold and the postoperative bone-conduction pure-tone threshold. The aim of this study was to compare the vibroplasty in vivo threshold with the postoperative speech recognition in patients with a high preoperative maximum word recognition score. STUDY DESIGN: Retrospective cohort study of German-speaking patients implanted with a vibrating ossicular prosthesis (VORP) 502 or VORP 503 and high preoperative maximum word recognition score between the years of 2011 and 2015...

INTRODUCTION: Temporal bone fractures are frequently associated with ossicular dislocations or fractures, most commonly involving the incus. To our knowledge, isolated fracture of the posterior crus of the stapes has not been previously reported. CASE REPORT: A 20-year-old man consulted for persistent left hypoacusis several months after a head injury. Initial computed tomography of the temporal bone showed a simple temporal bone fracture with no other associated abnormalities...

In cases of head trauma, the ear should be evaluated in all of its components. A good understanding of otologic and skull base anatomy enables a thorough trauma assessment of this complex anatomic region. Auricular laceration, abrasion, avulsion, hematoma, frostbite, otitis externa, exostosis, tympanic membrane perforation, ossicular discontinuity, perilymphatic fistula, labyrinthine concussion, temporal bone fracture, facial nerve paresis, and sensorineural hearing loss are a few of the more common otologic injuries seen in active patients...

The objective of this study was to analyze the results of endoscopy-assisted ear surgery for the treatment of chronic otitis media with cholesteatoma, adhesion, or retraction pockets.Fifty-one patients who underwent oto-endoscopy-assisted canal wall up tympanomastoid surgery and/or limited anterior atticotomy with tympanoplasty for chronic otitis media with cholesteatoma, adhesion, or retraction pocket from 2006 to 2013 have been included in this study. Eradication of the disease from the middle ear and mastoid air cells was achieved by combination of the oto-microscobic and oto-endoscopic approaches...

OBJECTIVE: The aim of this study was to compare the hearing results of embedding the partial ossicular reconstruction prosthesis (PORP) underneath the malleus with the malleus relocation technique and tympanic membrane graft in the presence of the malleus. MATERIALS AND METHODS: A retrospective review of patient charts and audiometric results in a tertiary referral center was conducted. In total, 83 patients who underwent intact canal tympanoplasty with mastoidectomy between 2010 and 2015 were included and divided into two different groups: malleus assembly to the stapes head (MASH) and tympanic membrane assembly to the stapes head (TASH)...

INTRODUCTION: The middle ear ossicles form a semi rigid chain in the middle of the ear for conduction and amplification of sound waves from the tympanic membrane to the inner ear. Although, our knowledge of the ear ossicles dates back to the 15(th) century, and various studies have been carried out on their morphometry, morphology, anomalies, embryology, function and structure throughout the world, information about the morphology of middle ear ossicles is meagre in Indian subjects. AIM: To find out the morphological variations of middle ear ossicles of right and left sides...

INTRODUCTION: Intracranial vascular, bone, and brain abnormalities might be observed in oculo-auriculo-vertebral spectrum (OAVS) patients even though these structures do not derive embryologically from the first and second pharyngeal arches. This neuroimaging study investigated their type, frequency and phenotype correlations among OAVS patients. METHODS: Thirty-five OAVS patients (mean-age 4.8 ± 6.0 years; age range 0.3-30, 14 females) underwent head CT (all patients) and brain MRI (32 patients); 19 patients had a more severe phenotype (Goldenhar syndrome)...

BACKGROUND: Hearing can be induced not only by airborne sounds (air conduction [AC]) and by the induction of skull vibrations by a bone vibrator (osseous bone conduction [BC]), but also by inducing vibrations of the soft tissues of the head, neck, and thorax. This hearing mode is called soft tissue conduction (STC) or nonosseous BC. PURPOSE: This study was designed to gain insight into the mechanism of STC auditory stimulation. RESEARCH DESIGN: Fluid was applied to the external auditory canal in normal participants and to the mastoidectomy common cavity in post-radical mastoidectomy patients...

Juveria Majeed, L Sudarshan Reddy
Chronic Suppurative Otitis Media (CSOM) is a chronic inflammation of middle ear cleft. It presents with discharging ear and decreased hearing. The diagnosis is mostly on clinical examination with otoscope or oto endoscope. Computerised Tomography (CT) of mastoids is done to evaluate the extent of the disease and its complication. High resolution CT is now the investigation of choice for temporal bone disease. This study emphasizes on the importance of CT scan in diagnosis of inflammatory ear diseases and most importantly identifying pitfalls or complications which a surgeon can come across during surgery...

OBJECTIVE: This study aimed to compare the functional and anatomical outcomes of ossiculoplasty using an autograft incus or a titanium partial ossicular replacement prosthesis for reconstructing Austin type A ossicular defects. METHODS: Patients with Austin A ossicular defects were randomly divided into two groups: one group underwent ossiculoplasty with an autologous incus (the autologous incus group) and the other underwent ossiculoplasty with a titanium partial ossicular replacement prosthesis (the titanium prosthesis group)...

Rinze Anthony Tange, Albert Mudry
OBJECTIVES/HYPOTHESES: In 1884, Johann Constantin August Lucae (1835-1911), a German otologist from Berlin, introduced a new "method to mechanically treat chronic troubles of the mobility of the hearing organ transmission apparatus." It consisted in the use of a springy pressure probe to directly mobilize the handle of the malleus. The aim of this study is to trace the invention, clinical use, technological modifications, and ultimate extinction of this instrument. METHOD: Review of Lucae's publications, comments by his colleagues, and trade catalogues published between 1880 and 1940...

Outcome Objectives To (1) explore audiometric outcomes following use of a combined transmastoid/middle cranial fossa (TM-MCF) approach in the treatment of spontaneous cerebrospinal fluid (CSF) otorrhea and (2) determine the influence of dehiscence location and reconstructive methodology on audiometric outcomes. Study Design Case series with chart review. Setting Tertiary care center. Subjects and Methods Adults with spontaneous CSF otorrhea were reviewed from 2007 to 2016 if they underwent combined TM-MCF. Definitive audiometric evaluations were performed at least 3 months postoperatively...

CONCLUSION: Evaluation of the follow-up of 67 patients shows that S53P4 bioactive glass (BAG) granules are safe and effective as obliteration material in cholesteatoma surgery. OBJECTIVES: To investigate the safety and efficacy of mastoid obliteration using S53P4 BAG in cholesteatoma surgery. Clinical outcomes were infection control (Merchant's grading), cholesteatoma recidivism, and audiometric performance. METHODS: Retrospective follow-up study at the Diakonessenhuis, Utrecht, the Netherlands...

Wei Dong, Ying Tian, Xin Gao, Timothy T K Jung
HYPOTHESIS: We hypothesize that current clinical treatment strategies for the disarticulated or eroded incus have the effect of combining the incus and stapes of the human middle ear (ME) into one rigid structure, which, while capable of adequately transmitting lower-frequency sounds, fails for higher frequencies. BACKGROUND: ME damage causes conductive hearing loss (CHL) and while great progress has been made in repairing or reconstructing damaged MEs, the outcomes are often far from ideal...

The active middle ear implant Vibrant Soundbridge© provides a variety of coupling modalities of the floating mass transducer (FMT) to various structures of the ossicular chain and the round window. A retrospective analysis was performed on 125 subjects (n = 137 ears) (1) to compare the efficacy of the different FMT coupling modalities with increasing degree of hearing loss, (2) to compare the performance in speech outcome and the effective gain between the coupling types, and (3) to evaluate the risk of additional hearing loss of each coupling procedure...
