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 ...

OBJECTIVES The direct acoustic cochlear implant (DACI) is among the latest developments in the field of implantable acoustic prostheses. The surgical procedure requires a mastoidectomy and a posterior-inferior tympanotomy, with access to the facial recess at the level of the oval window, in a complex and lengthy surgical approach. Here, we report a new and considerably shorter surgical approach...

In this article, a new tool for the intraoperative measurement of distances within the middle ear by means of a micromanipulator is presented. The purpose of this work was to offer the surgeon a highly accurate tool for measuring the distances between two points in the 3D operational field. The tool can be useful in various operations; this article focuses, however, on measuring the distance be...

Abstract. Convection influences climate and weather events over a wide range of spatial temporal scales. Therefore, accurate predictions the time location convection its development into severe are great importance. has to be parameterized in global models Earth system as key physical processes occur at scales much lower than model grid size. This parameterization is also used some numerical pr...

A retrospective analysis to quantify age-related changes of the incudo-malleolar joint (IMJ) and incudo-stapedial (ISJ), analyse in air-bone gap (ABG) with age, was performed.
