Unilateral microtia reconstruction: is the position symmetrical?

Area of Science:

• Plastic Surgery
• Otolaryngology
• Medical Imaging

Background:

• Microtia reconstruction requires precise evaluation of ear position.
• Lateral facial dysplasia is common in microtia patients, complicating reconstruction.
• Objective assessment methods are needed to evaluate surgical outcomes.

Purpose of the Study:

• To develop and apply a reproducible method for analyzing the head position of reconstructed unilateral microtic ears.
• To assess the accuracy of microtia ear reconstructions in relation to the normal ear.
• To evaluate the impact of lateral facial dysplasia on reconstruction outcomes.

Main Methods:

• A novel technique was developed to analyze reconstructed ear position relative to the normal ear.
• Measurements of length, angulation, and height were compared using standardized landmarks and a centimeter grid.
• The method was applied to 78 patients with unilateral microtia, divided into two groups based on the severity of lateral facial dysplasia.

Main Results:

• The developed technique proved reproducible for assessing reconstructed ear position.
• In Group I (mild to moderate dysplasia), 91% had acceptable ear length, 95% acceptable angulation, and 88% proper height.
• In Group II (severe dysplasia), results were comparable with 90% acceptable length, 95% acceptable angulation, and 90% proper height.

Conclusions:

• The developed method provides an objective evaluation of microtia ear reconstruction.
• Reconstructed ears achieved acceptable length, angulation, and height in most patients, even with severe facial dysplasia.
• Accurate positioning of the reconstructed ear is crucial for aesthetic and functional success.
