Summary

Ear reconstruction for Grade III microtia in South India achieved significant similarity in size, auriculocephalic angle, and conchal depth compared to the normal ear. This two-stage technique with custom prosthesis ensures stable, aesthetically pleasing results.

Area of Science:

  • Maxillofacial Surgery
  • Plastic Surgery
  • Otolaryngology

Background:

  • Reconstruction of Grade III microtia presents significant challenges in maxillofacial esthetic rehabilitation.
  • Various surgical philosophies and techniques exist for ear reconstruction.
  • This study details a South Indian experience with microtia reconstruction.

Purpose of the Study:

  • To present the outcomes of ear reconstruction in a South Indian population with Grade III microtia.
  • To evaluate the esthetic and geometric similarity of reconstructed ears to normal ears.

Main Methods:

  • A retrospective analysis of unilateral Grade III microtia reconstruction cases was conducted.
  • Inclusion and exclusion criteria were used for patient selection.
  • Measurements included ear size, auriculocephalic angle, and conchal depth, comparing reconstructed to normal ears.

Main Results:

  • Twenty-four patients underwent a two-stage reconstruction.
  • Reconstructed ears achieved 75% similarity in size, 79.94% in auriculocephalic angle, and 82.88% in conchal depth compared to normal ears.
  • Measurements demonstrated high accuracy and stability even after prolonged follow-up.

Conclusions:

  • The center utilizes a classic two-stage reconstruction method.
  • A customized prosthesis is employed to maintain projection geometry.
  • This technique minimizes complications such as adhesion, infection, and loss of structural stability.
