Cartilagem tragal com pericondrio em timpanoplastias

Abstract: Introdução: os enxertos de cartilagem começaram a ser usados por Jansen em 1963 que sugeriu que teriam sua indicação em casos mais avançados por ser mais rígido resistindo melhor à reabsorções e retrações. Em 1998 Eavey descreve o uso de cartilagem tragal com pericôndrio bilateral e a sua colocação sem incisões no meato acústico externo. Forma de estudo: clínico prospectivo randomizado. material e método: Foram estudados 100 pacientes portadores de seqüelas de otites médias crônicas, com perfurações da membran… Show more

“…Success rates of TM perforation closure with cartilage plugs in adults are high. Testa et al 20 reported a closure success rate of 96.8%, with hearing improvement in all the cases. These are the goals to be reached in children; however, low immunity, high rate of upper airway infection, and eustachian tube dysfunction are factors responsible for reducing the success rates of tympanoplasties in the pediatric population.…”

“…7,18,19 How-ever, the cartilage acoustic transfer characteristics are theoretically worse because of its thickness. 7,19,20 Zahnert et al 21 carried out an experimental study and concluded that 500-μmthick cartilage has acceptable acoustic transfer capacity with good mechanical stability.…”

“…It is thicker, less prone to resorption and retraction 4 . Nonetheless, the cartilage acoustic transfer characteristics are theoretically worse because of its thickness 2,4,6 . In 2000, Zahnert et al carried out an experimental study concluding that a 500μm-thick cartilage has an acceptable acoustic transfer capacity with good mechanical stability 14 .…”

“…In 1853, Toynbee introduced the "artificial eardrum", a small rubber disk with a silver rod -to facilitate introduction and extraction [1][2][3] . In 1878, Berthold, used a skin graft and in 1887, Blake recommended the use of a piece of paper as a template to tympanic membrane regeneration1.…”
