BACKGROUND The diagnostic performance of endoscopic and microscopic procedures for detecting diseases of the middle ear in patients with chronic otitis media (COM) has rarely been investigated. This study was conducted to compare the performance of these procedures for identifying middle ear structures and their associated diseases in COM patients. METHODS In this prospective cohort study, 58...

Non-coding microRNAs (miRNAs) have a fundamental role in gene regulation and expression in almost every multicellular organism. Only discovered in the last decade, miRNAs are already known to play a leading role in many aspects of disease. In the vertebrate inner ear, miRNAs are essential for controlling development and survival of hair cells. Moreover, dysregulation of miRNAs has been implicat...
