Anatomical and mechanical properties of the tympanic membrane
The middle ear is a small, complex three-dimensional (3-D) mechanical system that serves the physical function of collecting acoustical energy from a sound wave in air and passing it to the microscopic electro-mechanical sensory system of the inner ear. The system works over a very broad frequency range, has a large dynamic range and is able to function under greatly different static pressure c...
متن کاملStudies on Amphibian Metamorphosis Xvii. Influence of Non-living Annular Tympanic Cartilage on Tympanic Membrane Formation
INTRODUCTION THE tympanic membrane of the adult frog is divisible into three histologically distinct parts, viz. an inner epithelial layer, continuous with the mucous membrane of the tympanic cavity, the former being closely applied to a thin lamina propria conforming in shape and area to that of the annular tympanic cartilage to which it is attached at its peripheral borders. The third and out...
متن کاملCartilage tympanoplasty with island technique for reconstruction of tympanic membrane perforation: anatomic and audiologic results.
OBJECTIVES The aim of this study was to evaluate anatomic/audiologic outcomes of cartilage tympanoplasty with island technique and compare the results with the results of temporalis fascia tympanoplasty. PATIENTS AND METHODS The charts of 40 patients who underwent surgery for primary type 1 tympanoplasty either with perichondrium-cartilage (12 males, 11 females; mean age 29.7 years; range 12 ...

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...
15 صفحه اولEffects of tympanic membrane abnormalities on auditory function.
This article discusses how several diagnostic tools used by audiologists inter-relate to anatomical abnormalities viewed by video otoscopy. Background of common middle ear pathology is reviewed, with emphasis on new research findings regarding pathophysiology. A review of video otoscopy, multifrequency tympanometry, and otoreflectance is provided. Case studies illustrate the integrated use of t...
