Postoperative nausea and vomiting is an unpleasant, distressing, and exhausting experience for patient. This is more common and severe in tympanomastoid surgery. The role of dexamethasone prevention of this complication is unclear and during recent years much attention has been paid to it. In order to evaluate prophylactic effect of dexamethasone on postoperative nausea and vomiting after masto...

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. ...

In order to facilitate interoperability in a network composed of next generation lambda-switch-capable equipment, this document defines a standard lambda label format that is compliant with the Dense Wavelength Division Multiplexing (DWDM) and Coarse Wavelength Division Multiplexing (CWDM) grids defined by the International Telecommunication Union Telecommunication Standardization Sector. The l...

OBJECTIVE A previous pilot series described a hybrid mastoidectomy technique, canal wall window (CWW), which substituted for the canal wall down (CWD) procedure and involved slitting the posterior canal wall. The current, larger series compares the results of the CWW procedure with conventional surgical techniques. STUDY DESIGN Retrospective analysis of 78 pediatric ears. SETTING Academic t...

Despite the significant progress achieved in era of antibioticotherapy, the rate of suppurative complications of chronic otitis media (COM) remains alarming, and there is a growing evidence of unusual causative bacteria. We present a case of post-mastoidectomy wound infection caused by Enterococcus Foecalis that resulted in brain abscess and was resolved by means of a craniotomy with skull base...

Rhabdomyosarcoma is a rare tumour in the middle ear and mastoid cavity in children and the diagnosis is difficult. Repeated histological examination may be essential to confirm the diagnosis. We report a 6 year old boy with a left aural polyp, otorrhoea and facial nerve palsy who was initially thought to have otitis media and mastoiditis. He had polypectomy and the tissue taken for histopatholo...

Acute mastoiditis in the newborn is a very rare disease. Herein we report a case of a 28-day-old child with right aural atresia and ipsilateral mastoiditis requiring mastoidectomy. To our knowledge, this is the youngest case reported in the literature. Issues on diagnosis and management of mastoiditis in cases of aural atresia are further discussed. Based on our experience and on previous repor...

Now a days use of Triple play, online gaming and other real time applications are in demand. Present access network are a bottleneck due to bandwidth limitations. Passive optical networks technology (GPON and WDM PON) are the ultimate solution for the present and future. GPON is popular due to its capability to handle ATM and Ethernet data. CWDM is gaining more popularity due to its bandwidth o...
