Objective To review the advances in research on factors of cranioauricular angle formation after auricular reconstruction. Methods The related literature concing the main surgical methods and influencing factors for the ear elevation by Nataga method and dilated method was reviewed and summarized. Results The ear elevation by Nataga method and dilated method has achieved satisfactory clinical results. Although rapid prototyping technology and tissue engineering have developed rapidly, it is still some time before a beautiful and practical cranioauricular angle can be reconstructed. Conclusion The surgical programs for ear elevation by Nataga method and dilated method have been constantly improved in recent years, which provides a great deal of reference for obtaining a beautiful and practical cranioauricular angle.
