Although hearing prognosis varies from case to case, long duration of inflammation might have negative effects on the middle ear and the inner ear and lead to subsequent hearing loss, mainly conductive hearing loss because of a perforated membrane and ossicular
From June 2010 to March 2016, 43 patients were retrospectively evaluated in whom incus defect was detected with intact malleus and stapes during tympanoplasty operation in our clinic and ossicular
reconstruction was performed.
In cases in which the diagnosis is not obvious on otological examination, CT is helpful in demonstrating a soft tissue mass with characteristic ossicular
displacement and erosion of bone.
More importantly, even if open surgery in combination with ossicular
chain reconstruction can basically be comparable to canal wall up mastoidectomy due to the application of artificial ossicles and the advance in surgical techniques, with low risks of recurrence also.
We found that MRSA were seen in the safe type CSOM with ossicular
necrosis in the majority (29/33) of cases, but we do not know whether this is just by chance or there is a definite association between MRSA and ossicular
An extensive array of tumors can occur in the middle ear cavity which can cause CHL by interfering with normal ossicular
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).
As a result, air passes through the tube, and ossicular
chain function normally.
fusion was found in 48 cases (24%), and complete fusion was detected in 20 cases (10%) (Figure 1, 2).
A further cause of a conductive hearing loss is ossicular
chain disruption after trauma.
Piezo motors are being investigated to provide the longer range motion needed to adjust the initial applied load of the transducer on the ossicular
chain, which is critical to optimal performance of the implant.
In over 50 more articles they explain imagery in such cases as external otitis, exotoses, carcinomas and melanomas, ossicular
malformations, meningiomas, metastasis of the middle ear and mastoid, inner ear and petrous bone conditions such as epidermids and petreous apictis, trauma and fractures, the postoperative ear, and such conditions as Paget's Disease, Lymphoma and fibrous dysplasia.
