The objective of the present study was to characterize the epidemiological variants of tympanosclerosis and the effectiveness of the surgical treatment of the patients presenting with this condition. We have undertaken the analysis of the results of 1965 surgical interventions on the patients suffering from different forms of chronic otitis media (COM) performed during the period from 2009 till 2014 with a view to determining the frequency of tympanosclerosis (TSC). In 542 cases, it proved possible to evaluate the intraoperative findings, stages and methods of reconstructive surgery, the anatomical and functional outcomes and effectiveness of the intervention...

Aim of the present study is to evaluate the long term results of ossiculoplasty using titanium clip prosthesis. A retrospective analysis with prospective follow-up has been done including for all patients who had a Clip-PORP implanted between the years 2002-2013. Following this, audiometric hearing results were measured with clinical examination including otoscopy and quality of life evaluation using Glasgow benefit inventory. 48 patients (51 ears, 29 men, 19 women, average age 44.1 years) received followed up after an average duration of 6...

Techniques and biomaterials for reconstructive middle ear surgery are under steady, ongoing development. At the same time, clinical post-surgery results are evaluated to determine success or failure of the therapy. Routine quality assessment and assurance is of growing importance in the medical field, and therefore also in middle ear surgery. The exact definition and acquisition of outcome parameters is essential for both a comprehensive and detailed quality assurance. These parameters are not the audiological results alone, but also additional individual parameters which influence the postoperative outcome after tympanoplasty...

CONCLUSION: This study validates that a finite element model of the human ossicular chain and tympanic membrane can be used as an effective surgical assessment tool in clinics. OBJECTIVE: The present study was performed to investigate the application of a finite element model of ossicular chain and tympanic membrane for fabrication of individualized artificial ossicles. METHODS: Twenty patients (20 ears) who underwent surgery for middle ear disease (n = 20) and 10 healthy controls (10 ears) were enrolled in the hospital...

This manuscript intends to review types, pathogenesis, associated risk factors, and potential methods of prevention and treatment of the retraction pockets in adults and children. The importance of retraction pockets (RP) lies in loss of original histological and anatomical structure which is associated with development of ossicular chain erosion, cho¬lesteatoma formation and potentially life threatening complications of cholesteatoma. The trans-mucosal exchange each gas in the middle ear (ME) is towards equalizing its partial pressures with the partial pressure in the environ¬ment...

OBJECTIVE: We reviewed functional outcomes of tympanoplasty. STUDY DESIGN: The results of tympanoplastic surgery are changing in time. We present late treatment outcomes among different types of tympanoplasty. METHODS: Eighty-six patients who underwent tympanoplasty were enrolled in the study. The results of pure tone audiometry performed 7 days before, then at 3 months, 1 year, and 3 years after the surgery were assessed. Type II tympanoplasty involved implantation of a partial ossicular replacement prosthesis and type III tympanoplasty involved reconstruction with a total ossicular replacement prosthesis and the use of autogenous homogenous material...

Extramedullary hematopoiesis occurs in children with hemoglobinopathy and chronic anemia. The liver and spleen are often affected first, but other foci can develop to support erythrocyte demand. We report a case of a nine-year-old with beta thalassemia and temporal bone extramedullary hematopoiesis causing ossicular fixation and bilateral conductive hearing loss. There is only one case in the literature describing this phenomenon in pediatric patients, and this is the first case report of bilateral hearing loss from this physiologic phenomenon...

INTRODUCTION: Hearing loss as a sequel of chronic suppurative otitis media (CSOM) is often conductive, but recent studies have found an additional sensorineural component in these patients, thus demonstrating inner ear damage. The aim of the study was to determine the association between CSOM and sensorineural hearing loss (SNHL) and to assess the influence of patient's age, duration of disease, and presence of cholesteatoma and ossicular erosion on the degree of SNHL. METHODS: In a retrospective study, the medical records of 119 patients who underwent surgery was reviewed...

BACKGROUND: The learning curve for endoscopic tympanoplasty has never been quantitatively reported. The present study depicted the learning curve for endoscopic tympanoplasty and evaluated how many procedures an otologist requires to attain proficiency in this technique. METHODS: We reviewed the medical charts of consecutive patients who underwent endoscopic tympanoplasty between January 1, 2013 and June 1, 2015. We enrolled patients with simple perforations of the tympanic membrane and excluded those with ossicular chain disease...

Objective To systematically review the anatomy of the ossicular chain. Data Sources Google Scholar, PubMed, and otologic textbooks. Review Methods A systematic literature search was performed on January 26, 2015. Search terms used to discover articles consisted of combinations of 2 keywords. One keyword from both groups was used: [ ossicular, ossicle, malleus, incus, stapes] and [ morphology, morphometric, anatomy, variation, physiology], yielding more than 50,000 hits. Articles were then screened by title and abstract if they did not contain information relevant to human ossicular chain anatomy...

HYPOTHESIS: Custom prostheses could be used to recreate the ossicular chain and improve hearing. BACKGROUND: Ossicular discontinuity or fixation occurs in 55% of cases of conductive hearing loss, with most cases involving the incus. Reconstruction has been achieved by a variety of methods; however, there has been little improvement in hearing outcomes in decades. METHODS: Precise measurements of anatomic dimensions, weight, and center of gravity were taken from 19 cadaveric incudes...

MATERIALS AND METHODS: A retrospective single-institution cohort of 101 patients who underwent surgical treatment for recurrent chronic otitis media in a tertiary referral otology centre. RESULTS: Out of 101 patients, 65 had canal wall up and 36 canal wall down revision surgery. There were 35 cholesteatoma recurrences...

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...
