Middle ear implants in clinical practice
Ondrášková, Lucie ; Janoušek, Oto (referee) ; Provazník, Ivo (advisor)
The paper is a brief overview of anatomy of the ear, hearing screening, diseases and disorders affecting the organ of hearing. Next, there are listed the first ideas implants and their materials and there are described middle ear implants used nowadays and the latest surgical procedures, relevant legislation and the reaction of the body on the implant. The practical part will consist of collecting clinical data comprise the number and types of operations, air and speech audiometry and subsequent statistical evaluation. At the conclusion will be discussed and reviewed the statistics.

What happens to ear morphology on the way underground? A case study on the family Spalacidae.
PLEŠTILOVÁ, Lucie
This PhD thesis is concerned with the effect of specialization to the subterranean environment on ear morphology in the rodent family Spalacidae. The outer, middle and inner ear morphology in four species with a different proportion of subterranean activity was described and analyzed. The Chinese bamboo-rat (Rhizomys sinensis) was identified as fossorial regarding its ear morphology. The strictly subterranean Gansu zokor (Eospalax cansus) possess a highly specialized subterranean ear morphology with a suggested acoustic fovea. Meanwhile, the less subterranean African root-rat (Tachyoryctes splendens) shares traits with both strictly subterranean and epigeic rodents. The aboveground characteristics are even more prominent in the fossorial giant root-rat (T. macrocephalus). Taken together, the results confirm that the ear morphology of spalacids mirrors their degree of fossoriality.
