An Incus-Body Driving Type Piezoelectric Middle Ear Implant Design and Evaluation in 3D Computational Model and Temporal Bone
A new incus-body driving type transducer relying on piezoelectric stack, with broad frequency bandwidth, is proposed for use in a middle ear implant. To aid the design process of this transducer, a coupling biomechanical model of the human middle ear and the piezoelectric transducer was established by reverse engineering technology. The validity of this model was confirmed by comparing model pr...
متن کاملan investigation into iranian teachers consistency and bias in evaluation of students writings
while performance-based language assessment has led to an increased authenticity and content validity in the practice of writing assessment, the reliability of ratings has become a major issue. research findings have shown different reactions by native english speaker (nes) and non-native english speaker (nns) teachers to students’ writings. the focus of this study is on investigating whether i...
Leiomyosarcoma of the Middle Ear and Temporal Bone
Leiomyosarcoma is a malignant tumor of smooth muscle cells that is exceedingly rare in the middle ear and temporal bone. Wide surgical resection is treatment of choice and adjuvant treatment has not proven to be of benefit. This is a report on a patient with otorrhea and rapidly growing mass on postauricualr area. A tumor that was mainly located in the middle ear and temporal bone was surgicall...
متن کاملConcept and Evaluation of a New Piezoelectric Transducer for an Implantable Middle Ear Hearing Device
Implantable middle ear hearing devices (IMEHDs) have been developed as a new technology to overcome the limitations of conventional hearing aids. The piezoelectric cantilever transducers currently used in the IMEHDs have the advantages of low power consumption and ease of fabrication, but generate less high-frequency output. To address this problem, we proposed and designed a new piezoelectric ...
متن کاملAutomated approach for the segmentation of the incus and malleus middle ear bones in 3D CT images
Introduction The human auditory system includes the hearing and balance organs, and can be divided into three main elements: outer ear, middle ear and inner ear. The auditory ossicles are three very small bones: the malleus, incus and stapes, confined in the middle ear and coupled in chain. Their main function is to transmit sound energy from the tympanic membrane to the fluid-filled cochlea. A...
