Summary
This study presents a systematic surgical approach for correcting lop ear deformities, categorizing treatments by severity. The findings aim to clarify management strategies for congenital ear deformities.
Area of Science:
- Plastic Surgery
- Otolaryngology
- Congenital Deformities
Background:
- Lop ear deformity involves deficient helix/scapha and underdeveloped anthelix.
- Existing terminology and treatment for lop ears lack standardization.
- A systematic surgical approach is needed for this congenital ear deformity.
Purpose of the Study:
- To introduce a new, systematic surgical approach for lop ear deformity.
- To categorize surgical techniques based on deformity severity.
- To enhance clarity in managing lop ear cases.
Main Methods:
- Retrospective review of patients undergoing lop ear correction (2007-2019).
- Data collection on patient demographics, surgical techniques, and complications.
- Classification of lop ears into mild, moderate, and severe categories.
Main Results:
- Three surgical techniques were identified based on deformity severity.
- Mild lop ears treated with modified otoplasty.
- Moderate cases used extended otoplasty; severe cases required rib cartilage reconstruction.
- 109 patients with 146 lop ears (58 mild, 27 moderate, 61 severe) were analyzed.
Conclusions:
- A systematic approach simplifies management of lop ear deformities.
- Severe lop ears may represent a spectrum of conchal microtia.
- Tailoring surgical techniques to deformity severity improves outcomes.
