OBJECTIVE To determine the effectiveness of the Z-meatoplasty technique for enlargement of the external auditory meatus of children undergoing modified radical mastoidectomy. DESIGN Case series. SETTING Pediatric otolaryngology practice in an academic setting. PATIENTS Consecutive sample of children (< or =18 years old) who had undergone modified radical mastoidectomy performed by the aut...

OBJECTIVE Despite evidence that therapeutic mastoidectomy does not improve outcomes in noncholesteatomatous chronic otitis media, it remains widely performed. An up-to-date systematic review is undertaken and conclusions drawn regarding the best evidence-based practice of its management. DATA SOURCES PubMed, Google Scholar, Medline Embase, Cochrane, and Web of Science. REVIEW METHOD A combi...

BACKGROUND AND OBJECTIVES The aim of our study was to evaluate postoperative mastoid aeration according to the preoperative middle ear disease and investigate the factors affecting it. SUBJECTS AND METHODS We retrospectively reviewed the high-resolution computed tomography (CT) scans of temporal bones that were taken 1 year after surgery. The postoperative mastoid aeration was evaluated accor...

OBJECTIVES We evaluate the long-term surgical and hearing results using a canal wall down mastoidectomy technique followed by cavities obliteration, canal wall reconstruction and ossiculoplasty without staging. METHODS A total of 44 patients between January 2002 and October 2009 were selected and 27 of them were revision cases. Preoperative and postoperative pure tone average (PTA) and air-bo...

OBJECTIVES Autologous costal cartilage is a promising alternative for mastoid obliteration. However, donor-site morbidities of the chest wall limit the use of this graft. To address this issue, we have developed a minimally-invasive technique of harvesting costal cartilage and report donor site morbidity associated with the procedure. METHODS Donor site morbidities were evaluated for 151 pati...

OBJECTIVE To demonstrate the feasibility and complexities of cochlear implantation in the setting of bilateral temporal bone osteoradionecrosis. STUDY DESIGN Case report. SETTING Tertiary care referral centre. CASE DESCRIPTION A 66-year-old woman with bilateral temporal bone osteoradionecrosis and profound hearing loss, following treatment for tonsillar cancer, underwent cochlear implanta...

Introduction: Otorrhea and granulation tissue in Canal Wall Down mastoidectomy (CWD) is the common problem in cholesteatoma removal and leads to many discomfort for both the patient and the physician. The main objective in CWD is creating the dry cavity, so the topical antibiotic and acetic acid in variable saturations are used for this purpose. In this study we evaluate the effectiveness of to...

Coarse wavelength division multiplexing (CWDM)-targeted novel silicon (Si)-nanowire-type polarization-diversified optical demultiplexers were numerically analyzed and experimentally verified. The demultiplexer comprised a hybrid mode conversion-type polarization splitter rotator (PSR) delayed Mach–Zehnder interferometric demultiplexer. Si-nanowire-based devices fabricated using commercially ava...

We describe a hybrid Raman-optical parametric amplifier (HROPA) operating at the Oand E-bands and designed for coarse wavelength division multiplexed (CWDM) passive optical networks (PONs). We present the mathematical model and simulation results for the optimization of this HROPA design. Our analysis shows that separating the two amplification processes allows for optimization of each one sepa...

OBJECTIVES The Occupational Health and Safety Administration (OSHA) outlines specific requirements governing the use of respiratory protection for workers dealing with dust or other aerosolized compounds. Health care workers may be exposed to bone dust produced during otologic procedures, creating an occupational hazard. The purpose of this research was to quantify the total suspended particula...
