distraction osteogenesis (do), firstly introduced to the medical world by russian scientist ilizarov for long bone lenghtening in orthopedics can be considered as an appropriate substitute in the treatment of maxillofacial deformities. natural events occuring during the repair of a fractured bone segment not only lead to the desired bone length but also prevent from the undesired disadvantages ...

bone has a capability to repair itself when it is fractured. repair involves the generation of intermediatetissues, such as fibrous connective tissue, cartilage and woven bone, before final bone healing can occur. theprocess of cartilage-to-bone transition (cbt) is a key for the achievement of rigid bone healing duringfracture repair. we tested this potential for elastic cartilage using a long ...

Bone-anchored hearing aids are a widely used method of treating conductive hearing loss, but the benefit of bilateral implantation is limited due to interaural cross-talk. The present study measured the phase and level of pure tones reaching each cochlea from a single, mastoid placed bone transducer on normal hearing participants. In principle, the technique could be used to implement a cross-t...

Human listeners can perceive speech signals in a voicemodulated ultrasonic carrier from a bone-conduction stimulator, even if the listeners are patients with sensorineural hearing loss. Considering this fact, we have been developing a boneconducted ultrasonic hearing aid (BCUHA). The purpose of this study is to evaluate the usability of BCUHA regarding transmission of speaker discrimination inf...

Vestibular involvements have long been observed in otosclerotic patients. Among vestibular structures saccule has the closest anatomical proximity to the sclerotic foci, so it is the most prone vestibular structure to be affected during the otosclerosis process. The aim of this study was to investigate the saccular function in patients suffering from otosclerosis, by means of Vestibular Evoked ...

HYPOTHESIS The velocity response at the contralateral cochlea from bone-conducted (BC) stimulation depends on the stimulation position. BACKGROUND BC sound transmission in the human skull is complex and differs from air-conducted sound. BC sound stimulates both cochleae with different amplitudes and time delays influencing hearing perception in a way that is not completely understood. One imp...
