CLASSIFICATION OF CONGENITAL MIDDLE AND EXTERNAL EAR MALFORMATIONS: CT STUDY
The authors used high-resolution computed tomography (HRCT) for studying 52 congenitally malformed ears in 45 children between five and 10 years of age. In six children the malformations were bilateral. The malformations clinically manifested as microtia, atresia of the external auditory canal and conductive deafness. Analyzing anatomical details and pathological changes on HRCT axial sec...
متن کاملReconstruction of middle ear malformations
Malformations of the middle ear are classified as minor and major malformations. Minor malformations appear with regular external auditory canal, tympanic membrane and aerated middle ear space. The conducting hearing loss is due to fixation or interruption of the ossicular chain. The treatment is surgical, following the rules of ossiculoplasty and stapes surgery. In major malformations (congeni...

متن کاملMicro Screw Pump to Discharge Effusion from Human Middle Ear
In this paper we report the development of a micro screw pump for discharging effusion from middle ear for treatment of otitis media. This tool extrudes effusion using a newly designed screw, which rotates at 90,000 rpm in a pipe penetrated through tympanic membrane. This tool satisfies the discharge performance especially for high viscosity effusion while it has smaller diameter such as about ...
متن کاملReconstruction of Cochlea Based on Micro-CT and Histological Images of the Human Inner Ear
The study of the normal function and pathology of the inner ear has unique difficulties as it is inaccessible during life and, so, conventional techniques of pathologic studies such as biopsy and surgical excision are not feasible, without further impairing function. Mathematical modelling is therefore particularly attractive as a tool in researching the cochlea and its pathology. The first ste...
