Methods for producing a custom-made stapes prosthesis for a patient and stapes prostheses so produced. The methods may include obtaining a three-dimensional image of a natural stapes bone of the patient; and forming a stapes prosthesis that closely approximates a three-dimensional shape of the ...
The tiny titanium connection between the middle and the side legs of the SH-coupler still allows to add a reflector on the bone (Figure 1). A larger reflector diameter was chosen at the RW and placed in the centre of the membrane. We thereby assume that the primary, mechanically ...
Aberrant behavior of phosphofructokinase from otosclerotic stapedes. Biochemical evidence and the metabolic consequences Bullate stapedes in some phalangeriform marsupials Biochemical studies of otosclerosis. Protein and enzymes in stapedes and cortical bone. ...
Otosclerosis is a primary disease of multifactorial etiology, mostly involving the process of bone tissue remodeling in various areas of the temporal bone. Vascular proliferation, bone resorption, and the formation of new bone tissue observed histologically most often concern the area of the oval windo...
It was believed to be asymptomatic otosclerosis. An unusual pattern of radial striations in the underlying bony matrix was observed. Large multiloculated cysts were found containing nests of foamy histocytes. The value of scanning electron microscopy in bone pathology is discussed....
Preliminary results in human subjects showed excellent air-bone closure. The Nitinol loop holds uniform contact around the incus. Conclusions: The Nitinol piston greatly simplifies the stapedectomy procedure by taking the need for a hand operated instrument out of the surgeon's hands. Because of ...
The air–bone gap (ABG) was calculated using pure tone averages (PTA) of the commonly obtained frequencies 0.5, 1, 2, and 3 kHz. In few cases, audiometric data for 3 kHz was missing and was therefore calculated by averaging the meas- ured thresholds at 2 and 4 kHz as ...

Of the 127 ears, 123 (96.9%) had postoperative air-conduction threshold improvements of better than 15 dB at speech frequencies; 119 (93.7%) improved within 15 dB or better between preoperative bone-conduction thresholds and postoperative air-conduction thresholds. However, only 76 ears (59.8%) ...
The localization and extent of the oto-sclerotic foci in the oval window niche were studied in 66 human temporal bone specimens. The bones were cut in serial sections of 20 microns. According to the size of the otosclerotic focus and the degree of stapes fixation, the material is divided ...
