Reconstructing the mastoid cavity often requires canal wall reconstruction to restore middle ear anatomy. This study reviews various materials used over twenty years, including a new titanium prosthesis, to improve surgical outcomes.

Area of Science:

  • Otolaryngology
  • Surgical Reconstruction
  • Middle Ear Surgery

Background:

  • Management of problematic mastoid cavities frequently necessitates canal wall reconstruction.
  • Restoring middle ear anatomy is crucial for effective wound healing in both epidermal and mucosal layers.

Purpose of the Study:

  • To evaluate the effectiveness of different materials and surgical techniques for long canal wall reconstruction.
  • To compare traditional materials with a newer titanium prosthesis for improved anatomical results.

Main Methods:

  • Review of 386 cases performed over twenty years.
  • Utilized materials include cortical bone, ear canal allograft, ceravital, porous and dense hydroxylapatite.
  • Introduction and assessment of a novel titanium prosthesis for reconstruction.

Main Results:

  • The difficulty of ear canal reconstruction is highlighted by the variety of materials and procedures employed.
  • The study discusses the advantages and disadvantages of each material and prosthesis used.

Conclusions:

  • Canal wall reconstruction is a key component in managing mastoid cavities.
  • Ongoing evaluation of materials like titanium prostheses is essential for optimizing surgical outcomes in middle ear reconstruction.
