Microtia reconstruction: does the cartilage framework grow?
Abstract
The use of free rib cartilage ear frameworks in unilateral microtia reconstruction has prompted much discussion about their potential for growth. The senior author has reconstructed ear frameworks in 132 microtia patients, most of whom were under 3 years of age when surgery was initiated. Of this group, 29 were assessed for ear growth through comparison of the lead-plate model of the original normal ear to the normal ear growth and the reconstructed ear framework after a period of at least 2 years. Similarly, 14 reconstructed ears were compared to 14 normal ears at least 2 years after reconstruction. The perimeters of tracings made from the original lead plates and of tracings of normal and reconstructed ears were determined by image analysis techniques. The results demonstrated no significant difference in growth between normal ears and reconstructed ear frameworks after an interval of at least 2.5 years. Therefore, the reconstructed ear is growing at a rate similar to that of the normal ear.
