AO CMF Global Study Club

Topic description

Aural atresia and microtia are both the results of failure of the ectoderm of the 1st and 2nd brachial arches that results in underdevelopment of the middle and out ear structures and auricle. The Marx classification system is most used to grade microtia. CT imaging is required to evaluate atresia using the Jahrsdoerfer grading system. Hearing outcomes can be excellent with bone conduction systems, even without atresia repair. There are three main methods of reconstructing the auricle: 1) autologous rib reconstruction, 2) Synthetic ear reconstruction with Temporoparietal flap coverage, and 3) prosthetic reconstruction. Each has risks and advantages. In this study club event we discuss specific techniques for microtia reconstruction, including: how to harvest rib cartilage, how to carve the cartilage and manufacture an ear construct, methods of elevating the construct, and techniques for elevating a temporoparietal fascia flap.
