Research on Ossicular Chain Mechanics Model
On account of the complex structure of the middle ear and that it is more difficult to carry out experiments to test the nature of the mechanical components, the relevant data is hard to obtain, which has become an obstacle restricting analysis of the middle ear mechanic. Based on spatial structure and mechanical properties of ossicular chain, the paper has established functional relationship b...
متن کاملOssicular chain lesions in cholesteatoma
The aim of the study was to describe ossicle resorption in chronic otitis with cholesteatoma and correlate it with clinical parameters such as age, contralateral ear condition, tympanic membrane aspect, cholesteatoma pathogenesis and extension, associated lesions and hearing threshold. Preoperative clinical data were collected for 140 patients with chronic otitis with cholesteatoma, whose ossic...
متن کاملStatistical mechanics of helical wormlike chain model.
We investigate the statistical mechanics of polymers with bending and torsional elasticity described by the helical wormlike model. Noticing that the energy function is factorizable, we provide a numerical method to solve the model using a transfer matrix formulation. The tangent-tangent and binormal-binormal correlation functions have been calculated and displayed rich profiles which are sensi...
متن کاملSurgical reconstruction of the ossicular chain with custom 3D printed ossicular prosthesis
Background: Conductive hearing loss due to ossicular abnormalities occurs from many causes, including trauma, infection, cholesteatoma, surgery and congenital anomalies. Surgical reconstruction of the ossicular chain is a wellestablished procedure for repair of ossicular defects, but is still plagued by high failure rates. Underlying disease and proper sizing of prostheses are two challenges th...
متن کامل[Ossicular chain injury due to the head trauma].
Nineteen cases of ossicular chain separation and ossicular dislocation due to head injury were presented. These cases were operated at an early stage after the trauma. The malleus was almost always involved in ossicular chain injury, while the incus was involved in 42% of our cases. The stapes was involved in 21%. The incudo-mallear joint is always separated while the incudo-stapedial joint is ...
