Introduction and Overview
CHAPTER 1 INTRODUCTION AND OVERVIEW All otitis media is middle-ear disease, but middle-ear disease includes more than otitis media, such as Eustachian tube (ET) dysfunction, myringosclerosis, tympanosclerosis, ossicular congenital and…
Pathogenesis
CHAPTER 6 PATHOGENESIS Pathogenesis of middle-ear effusion owing to the hydrops ex vacuo theory is now evidence-based from studies in humans and animals. The chapter includes • The role of the…
Epidemiology
CHAPTER 2 EPIDEMIOLOGY Status of the function of the ET is an important factor in the epidemiology of middle-ear disease. The chapter includes • The importance of otitis media as a…
