A custom positioning aid for an auricular prosthesis: A clinical report.

This report describes the treatment of a 68-year-old man with basosquamous cell carcinoma of the left auricular area. His oncologic treatment resulted in the loss of his left ear and much of the left temporal bone. The loss of a significant portion of the temporal bone precluded the use of extraoral implants. Owing to the lack of anatomic landmarks after his surgical treatment, positioning his auricular prosthesis proved challenging. The fabrication of his prosthesis and a custom positioning aid are described.
