Classification and Algorithmic Management of Constricted Ears: A 22-Year Experience

Area of Science:

• Plastic Surgery
• Otolaryngology
• Aesthetic Medicine

Background:

• Classification and surgical correction of constricted ears remain controversial.
• This study analyzes 164 ear cases from 1992-2014 to address these controversies.

Purpose of the Study:

• To clarify the classification and corrective methods for constricted ears.
• To evaluate the effectiveness of a graded surgical approach and associated aesthetic outcomes.

Main Methods:

• A retrospective review of 164 constricted ear cases (excluding microtia) was conducted.
• Ears were classified into four grades using specific clinical tests.
• Surgical techniques included antihelical tubing, cartilage grafting, and helical expansion.

Main Results:

• Four grades of constricted ears were identified (Type I: 21, Type II: 63, Type III: 38, Type IV: 42).
• 144 cases (88%) were followed post-surgery, with an average aesthetic outcome score of 3.3 (good to excellent).
• Specific corrective methods and outcomes for each grade were detailed.

Conclusions:

• A graded surgical approach effectively corrects constricted ears in a single stage.
• Deformed auricular cartilage was preserved during correction, leading to favorable aesthetic results.
