The “C-Bending-Spring-Tympanoplasty” for Reconstruction of Anterior Tympanic Membrane Defects: A Prospective Randomized Clinical Trial

CBST allows for comparably high success rates of reconstruction of anterior TM defects and the hearing outcome. Accordingly, the U-spring bending cartilage supporting the graft does not adversely affect hearing outcome. Thus, CBST can be considered a useful technique to close anterior defects of the TM effectively.
