Chondrodermatitis nodularis chronica helicis excision and reconstruction

Area of Science:

• Dermatology
• Plastic Surgery
• Otolaryngology

Background:

• Chondrodermatitis nodularis chronica helicis (CNCH) is a common, benign ear condition.
• Presents as a painful, well-demarcated nodule on the pinna, potentially with erythema or crusting.

Purpose of the Study:

• To describe surgical techniques for CNCH excision.
• To detail reconstruction methods for resulting defects on the helix and anti-helix.

Main Methods:

• Surgical excision of the nodule.
• Reconstruction of the defect following excision.
• Smoothing of underlying cartilage to achieve a smooth ear contour.

Main Results:

• Excellent cosmetic outcomes achieved with described techniques.
• Procedures can be performed effectively under local anesthesia.

Conclusions:

• Surgical excision and cartilage smoothing are effective for CNCH.
• Achieving a smooth contour reduces the probability of lesion recurrence.
