Abstract

Acellular Human Dermal Allograft in Canal Wall Down Mastoidectomy and Considerations of Graft Thickness

Objectives/Hypothesis: Describe our method and results to observe the optimal thickness of AlloDerm used in canal-wall-down mastoidectomy defects.

Study Design: Retrospective consecutive case series.

Methods: AlloDerm with an average thickness of 0.33 to 0.76 mm was used; selecting the portions of tissue with a thickness closest to 0.5 mm to line mastoid cavity defects. Failures occurred when AlloDerm’s thickness was beyond the average of 0.76mm. We report time to healing as well as long term results including need for revision surgery and skin breakdown.

Keywords: AlloDerm; Mastoid; Mastoidectomy; Cholesteatoma
