Plastic Surgery
Otolaryngology
Medical Device Evaluation

Background:

Unilateral microtia presents aesthetic and functional challenges.
Accurate reconstruction of the auricle is crucial for patient outcomes.
Standardized methods for ear reconstruction positioning are needed.

Purpose of the Study:

To evaluate the effectiveness of a novel positioning ruler for reconstructed auricles.
To determine if the ruler facilitates symmetrical ear reconstruction in microtia patients.

Main Methods:

A cohort of 47 patients with unilateral microtia was studied.
Measurements were taken comparing the reconstructed auricle to the contralateral normal ear.
Key distances (highest, lowest points to nasal axis, height) were analyzed.

Main Results:

No significant difference was found between reconstructed and normal auricle dimensions.
Symmetry was achieved in auricle positioning relative to the nose.
Statistical analysis confirmed the reproducibility of measurements (P>0.05).

Conclusions:

The evaluated positioning ruler is a simple and user-friendly device.
The ruler provides accurate and non-invasive measurements for ear reconstruction.
This tool can aid surgeons in achieving symmetrical auricle reconstruction.
