Recurrent painful ear nodules can be minimized by a surgical technique that smooths the transition from normal skin to the defect. This involves undermining skin and cartilage and trimming cartilage spikes at the excision site.

Area of Science:

  • Dermatology
  • Surgical Oncology
  • Otolaryngology

Background:

  • Painful nodules on the ear, often recurring after surgical excision.
  • Standard excision techniques can lead to high recurrence rates at the helical rim.

Purpose of the Study:

  • To present a surgical modification to reduce recurrence of painful ear nodules.
  • To achieve a smoother transition between normal helical rim and excision defect.

Main Methods:

  • Undermining the skin and cartilage at the ellipse ends.
  • Trimming cartilage spikes to create a smooth contour.

Main Results:

  • The described technique facilitates a smooth transition from the normal helical rim to the defect.

  • Minimizes the risk of recurrence at the tips of the excision ellipse.

    • Conclusions:

    • This surgical modification is effective in reducing the recurrence of painful ear nodules.
    • A smooth contouring of the cartilage is key to preventing post-excision recurrence.
