Summary

An external stretching device effectively corrects cryptotia (inverted ear) in patients aged 10-40. Combining it with surgery for severe cases yields excellent, lasting results.

Area of Science:

  • Plastic and Reconstructive Surgery
  • Otolaryngology

Background:

  • Cryptotia, a congenital ear deformity, presents challenges in achieving permanent correction.
  • Traditional methods may require prolonged treatment durations or yield suboptimal aesthetic outcomes.

Observation:

  • An external stretching device was utilized for cryptotia correction in 27 patients (ages 10-40).
  • Initial trials using the device alone required over 5 months for sustained ear projection, with some cases experiencing pin site infections.
  • A modified approach combined surgical release of severe cartilage adhesions with skin grafting, followed by the external stretching device for 2 months.

Findings:

  • The combined surgical and device approach resulted in excellent long-term outcomes, including well-maintained ear projection and satisfactory auricular shape.

  • The external stretching device, particularly when combined with surgical intervention, demonstrated efficacy in correcting cryptotia, even in cases with significant cartilage adhesion.

    • Implications:

    • The external stretching device offers a viable, potentially shorter-term alternative for correcting cryptotia, especially in older children and adults with severe cartilage adhesion.
    • This approach may improve patient compliance and reduce treatment duration compared to device-only methods.
    • Further research could explore optimizing the device's design and application protocols to minimize complications like pin site infections.
