The external ear (pinna and earcanal) plays a major role in transforming acoustic signals from free field to the tympanic membrane in humans. It acts as a filter to reduce low frequencies, a resonator to enhance mid frequencies (2.0 to 7.0 kHz), and a direction-dependent filter at high frequencies to augment spatial perception. The external ear transfer function is altered by variations in the ...

Our aim in this study is to show the efficacy of trichloracetic acid cauterization in the tympanic membrane perforations. Between January 2002 and January 2012 central perforations in 160 ears of 142 cases were tried to be closed by repeated trichloracetic acid cauterization in one week interval followed by the placement of a piece of cigarette paper to the perforation site. In 98 of 137 ears (...
