This study introduces a new endaural meatoplasty technique for open mastoidectomy. The endaural approach offers precise control over cartilage removal, improving outcomes for mastoid cavity stability and eardrum integrity.

Area of Science:

  • Otolaryngology
  • Surgical Techniques
  • Mastoidectomy

Context:

  • Traditional meatoplasty often uses a retroauricular incision.
  • A new endaural meatoplasty approach has been developed.
  • This technique is performed at the beginning of open mastoidectomy.

Purpose:

  • To describe and evaluate a novel endaural meatoplasty technique.
  • To assess the predictability of external canal width.
  • To determine the utility of removed cartilage for middle-ear reconstruction.

Summary:

  • Two hundred twenty-seven endaural meatoplasties were performed over six years, primarily during open mastoidectomy.
  • The procedure allows precise shaping of conchal cartilage and prediction of external canal dimensions.

  • Excellent results were observed, with only 1.4% unstable mastoid cavities and 2.24% persistent eardrum perforations after three years.

    • Impact:

    • Enables precise design of conchal cartilage removal and external canal volume.
    • Facilitates harvesting of a cartilaginous conchal fragment with perichondrium for reconstruction.
    • Provides broad mastoid exposure when performed early in the surgical procedure.
