Purpose: This study evaluated the utility of a ruler for reconstructed article positioning.
Methods: Forty-seven patients with unilateral microtia were selected from August 2020 to September 2021.
Results: The linear distance from the highest point of the reconstructed auricle to the central axis of the nose was not significantly different from the distance from the highest point of the normal contralateral auricle to the central axis of the nose (P> 0.05). The distance from the lowest point of the reconstructed auricle to the central axis of the nose was not significantly different from the distance from the lowest point of the normal auricle to the central axis of the nose (P> 0.05). The linear distance from the highest to the lowest point of the reconstructed auricle was not significantly different from the distance from the highest to the lowest point of the normal auricle (P> 0.05). These results indicate that the reconstructed auricle was symmetrical to the contralateral ear.
Conclusion: The positioning ruler evaluated in this study is simple, easy to use, accurate, and non-invasive.
