Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Biomaterials Science

Background:

  • The decision to remove the posterior external canal wall during mastoid surgery is a long-standing debate with pros and cons.
  • Surgical techniques must be individualized based on patient-specific factors.

Purpose of the Study:

  • To present an approach combining external canal wall reconstruction and mastoid obliteration using hydroxyapatite.
  • To evaluate the efficacy and outcomes of this combined technique in mastoid surgery.

Main Methods:

  • Utilized hydroxyapatite in three forms: granules, a preformed prosthesis, and a custom-sculpted block.
  • Reconstructed the external canal wall and obliterated the mastoid in 36 patients.
  • Followed patients for up to 54 months to assess outcomes.
