3-dimensional (3-D) Template Model-A Useful Adjuvant Tool in Secondary Ear Reconstruction

Abstract

Unfavorable results in reconstruction of the auricle for microtia can be encountered from time to time, in which secondary reconstruction of the auricle is usually performed. For the less experienced reconstructive surgeon, use of a complete three-dimensional template would theoretically allow one or more accurately estimates of skin flaps, especially in secondary reconstruction due to the scar tissue, necrotic skin and loss of tensility in subdermal layer. Using the 3-dimensional template as reference may have several benefits as follows: 1. guiding one in the creation of the more complicated portions of the cartilage framework, 2. helping surgeon to assess the adequacy of enveloping skin flap 3. aiding inexperienced operators by reducing carving and assembling time as well as providing a reference in the fabrication process of cartilage framework. For these reasons, three-dimensional templates were created in secondary auricular reconstruction. This paper presents the 2-year experience with 8 cases of secondary auricular reconstruction in which three-dimensional templates are used as an intraoperative aid.
