Background and Objectives: Postoperative nausea vomiting (PONV) is a common adverse effect of general anesthesia, especially in middle ear surgery. Remimazolam newer benzodiazepine recently approved for use anesthesia. This study aimed to compare the incidence rate PONV after tympanoplasty with mastoidectomy between using remimazolam sevoflurane. Materials Methods: included 80 patients undergoi...

A 36-year-old male who had history of hearing loss since childhood presented with a chronically discharging right ear. HRCT temporal bones revealed non-dependent opacification in the epiand meso-tympanum with medially displaced head of malleus, erosion of incus and the tegmen tympani suspicious for an attic cholesteatoma. In addition, there was a serpiginous structure seen extending across the ...

We reviewed our series of surgeries for paediatric cholesteatoma to assess outcomes and functional results considering the extension of disease and surgical techniques. Between January 2003 and December 2009, 36 patients (range 6-14 years) were operated on for cholesteatoma. We considered the sites involved by the cholesteatoma (mastoid, antrum, attic, middle ear, Eustachian tube), surgical tec...

In this paper, a four channel Coarse Wavelength Division Multiplexing (CWDM) network is designed by incorporating the proposed and designed Two Dimensional (2D) Photonic Crystal Ring Resonator (PCRR) based Add Drop Filter (ADF). The performance parameters of the network such as the received output power, Bit Error Rate (BER) and Q factor are examined for the bit rate of 10 Gbps over the fiber l...
