A modified technique for fabricating a mirror image wax pattern for an auricular prosthesis.

Creating accurate auricular prostheses remains a challenge in reconstructive surgery. Traditional methods often rely on direct impressions or digital scans. However, these approaches may not always capture the fine anatomical details necessary for a mirror image. Prior research has shown that indirect methods can be effective, but gaps remain in achieving high precision and replicability. That uncertainty drove the development of alternative fabrication techniques. No prior work had resolved the issue of replicating the contralateral ear with minimal distortion. This gap motivated the exploration of a wax-based approach. The need for a reliable and repeatable method is clear. The search for a technique that balances precision and practicality continues.

The aim of this study is to introduce a modified technique for producing a mirror image wax pattern of the contralateral ear. This method seeks to improve the accuracy of auricular prostheses by using a slicing approach. The problem addressed is the difficulty in replicating the ear's complex geometry. The motivation stems from the limitations of current indirect methods. The study focuses on a step-by-step process involving modeling wax and sliced casts. This approach allows for the reversal of each slice to form a mirrored structure. The goal is to enhance the fidelity of the final prosthesis. The method aims to be both practical and precise for clinical use.

The process begins by creating a cast of the contralateral ear. This cast is sliced at 1-mm intervals to capture the ear's shape. Each slice is then traced onto a wax sheet of the same dimensions. The traced wax slices are reversed to form a mirror image. These reversed slices are stacked to build the wax pattern. The stacking ensures that the final model reflects the original ear's structure. The technique relies on manual precision and careful alignment. The method emphasizes replicability and anatomical accuracy.

The technique successfully produced a mirror image wax pattern of the contralateral ear. Each 1-mm slice was accurately transferred to the wax sheet. The reversed slices were stacked to form a complete model. The final wax pattern maintained the original ear's anatomical details. The method demonstrated high precision in replicating the ear's shape. The stacking process did not introduce significant distortion. The mirrored structure was consistent with the original cast. The results suggest the method is both reliable and repeatable.

The authors propose that this technique offers a practical method for creating auricular prostheses. The use of 1-mm slices and wax sheets allows for accurate replication. The reversal of each slice ensures a mirror image is formed. The stacking process maintains the original ear's structure. The method does not require advanced digital tools. It may be particularly useful in clinical settings with limited resources. The results suggest the technique is suitable for routine use. The authors suggest further evaluation to confirm its widespread applicability.
