The chronic inflammation leads to deposition of hyalinized collagen that can calcify, often associated with calcification of the ossicular ligaments and tendons.
All other ear injuries occurred in less than 1 percent of the sample, including ear canal injury (n = 23); inner or middle ear injury, not further specified (n = 5), bilateral (n = 0), or involving dizziness (n = 12); ossicular chain (ear bone) dislocation (n = 1), bilateral (n = 0); and vestibular apparatus injury (n = 1).
In those patients with conductive hearing loss, an ossicular abnormality has been shown on only three occasions [6].
1) It is not known which losses or what percentage of losses is attributable to ossicular manipulation or to acoustic trauma to the cochlea.
Ossicular disruption results in a conductive hearing loss, and with surgical repair, patients regain much of their hearing at the lower frequencies [18].
The Direct Drive Demonstrator is a battery-powered system that consists of an MP-3 player and Symphonix' proprietary technology, the Floating Mass Transducer(TM) (FMT), which is a tiny transducer that directly vibrates the middle ear by mimicking the natural motion of the ossicular chain, sending an enhanced signal to the cochlea.
The jugular bulb was located apart from the cholesteatoma and the ossicular chain.
We conducted a study to assess the use of the chorda tympani nerve in reconstruction of the ossicular chain.
Although one would expect blast waves to cause tympanic membrane rupture and ossicular disruption (thus resulting in conductive hearing loss), available audiology reports showed that pure sensorineural loss was the most prevalent type of hearing loss in patients with BR TBI.
The hearing loss is usually conductive, resulting from tympanic membrane rupture and/or changes in the ossicular chain secondary to fixation or erosion caused by the chronic inflammatory process.
The ensuing pressure variations result in vibrations of the tympanic membrane (TM), which lead to movement of the ossicular chain of the middle ear (Figure 1).
