The concept of an artificial tympanic membrane.
A review is given of the development of the concept of an artificial tympanic membrane. Starting with homologous tympanic membranes we compared biodegradable collagen materials (homologous and heterologous) and biodegradable synthetic materials, poly-glycolic acid, poly-lactic acid and poly-alpha-amino acids. As a non-degradable material microporous PTFE and bisphenol-A poly (carbonate) were in...
متن کاملTympanosclerosis in the tympanic membrane: influence on outcome of myringoplasty.
The effect of the presence of tympanosclerotic plaques in tympanic membrane on the outcome of a myringoplasty procedure was evaluated in this retrospective study. Long-term results of 714 myringoplasties were analyzed, and of these, 555 were eligible for further study. Three groups were studied separately: ears without tympanosclerosis, ears with a plaque not exceeding one third of the tympanic...
متن کاملTwo Mathematical Models for the Tympanic Membrane
In this project we present two mathematical models for the human tympanic membrane. The eardrum can be viewed as an example of the vibrating drum problem. In the first model, we treat the tympanic membrane as a rectangular region. In the second model the tympanic membrane is considered as a disk. Both models use a wave equations. We study the impact of changes in the membrane tension related to...
متن کاملOssicular calisthenics: Pneumomassage of the tympanic membrane.
OBJECTIVES/HYPOTHESIS Throughout the latter portion of the 19th and early 20th centuries, pneumomassage devices were widely used by otologists to treat a variety of ear diseases. The so-called eardrum massagers produced a regular, repetitive, oscillatory movement through modifying the air pressure in the ear canal. The goal of this study was to trace the invention, clinical use, technological d...
متن کاملWave model of the cat tympanic membrane.
In order to better understand signal propagation in the ear, a time-domain model of the tympanic membrane (TM) and of the ossicular chain (OC) is derived for the cat. Ossicles are represented by a two-port network and the TM is discretized into a series of transmission lines, each one characterized by its own delay and reflection coefficient. Volume velocity samples are distributed along the ea...
