OBJECTIVE To compare the outcome and success of repair of uncomplicated tympanic membrane perforations with myringoplasty alone and when combined with mastoidectomy. METHODS A prospective study where 40 patients with non-cholesteatomatous chronic suppurative otitis media (CSOM) were recruited during the period of June 2013 to December 2013 from the outpatient clinic of Otorhinolaryngology dep...

HYPOTHESIS Using image-guided surgical techniques, we propose that an industrial robot can be programmed to safely, effectively, and efficiently perform a mastoidectomy. BACKGROUND Whereas robotics is a mature field in many surgical applications, robots have yet to be clinically used in otologic surgery despite significant advantages including reliability and precision. METHODS We designed ...

Glomus tympanicum, a hypervascular tumor in the middle ear, is usually suspected based on pulsatile tinnitus and retrotympanic reddish mass on otoscopic examination. These hallmarks may be masked by other middle ear diseases. Herein, we report an unusual case of the extensive glomus tympanicum masqueraded as chronic granulomatous otitis media, which was extirpated without preoperative embolizat...

INTRODUCTION First branchial cleft anomalies manifest with duplication of the external auditory canal. CASE REPORT This report features a rare case of microtia and congenital middle ear and canal cholesteatoma with first branchial fistula. External auditory canal stenosis was complicated by middle ear and external canal cholesteatoma, but branchial fistula, opening in the zygomatic root and a...

Introduction  Canal wall down (CWD) mastoidectomy has many drawbacks, including chronic otorrhea not responding to medications, granulations, dizziness on exposure to cold or hot water, and tendency of debris accumulation in the mastoid cavity, demanding periodic cleaning. Many of these problems can be solved by reconstruction of the posterior meatal wall (PMW). Objectives  To assess the result...

The traffic flow in long-haul dense wavelength division multiplexing fiber networks has surpassed by far the traffic deliverability from/to the access network thus creating what is known as “access bottleneck”. This bottleneck was the result of two major factors, the inherent cost sensitivity of access networks that impedes deployment of new optical technology prior to cost maturity, and the la...

the aims of surgical treatment for cholesteatoma include complete removal of disease and formation of a dry, self cleaning ear in addition to hearing reconstruction. this presentation concentrates on techniques of open mastoid surgery or modified radical mastoidectomy to achieve a well-constructed cavity. this study analyzes both primary and revision mastoid surgery referred to the author. all ...

Presently, high-speed and wide-bandwidth broadband access systems such as ADSL, CATV and FTTH have become widespread. With respect to the data sent and received in such systems, those not only of text but also from multi-media fields --such as moving images and audio-have grown in volume, and tend to increase hereafter. Thus, metro/access networks that connect subscribers with a trunk network a...
