Summary

Hydroxyapatite cement (HAC) is highly effective for temporal bone reconstruction, with a 97% success rate in repairing defects. This biomaterial restores temporal bone integrity and prevents complications like cerebrospinal fluid leaks.

Area of Science:

  • Neurosurgery
  • Biomaterials Science
  • Otology

Background:

  • Temporal bone defects arise from various conditions including skull base surgery, infections, neoplasms, and congenital anomalies.
  • Reconstruction of these defects is crucial for restoring function and preventing complications.

Purpose of the Study:

  • To evaluate the indications and success rate of hydroxyapatite cement (HAC) in temporal bone reconstruction.
  • To assess the long-term stability and complications associated with HAC use.

Main Methods:

  • Retrospective case review of 109 temporal bone defects in 102 patients (adults and children).
  • Defects were reconstructed using HAC over a 10-year period.
  • Data on outcomes and complications were collected via chart review.

Main Results:

  • Successful repair of 97% of temporal bone defects using HAC, with stable reconstructions.
  • One case of postoperative cerebrospinal fluid leak.
  • Three cases of wound infection requiring reoperation and biomaterial removal.

Conclusions:

  • Hydroxyapatite cement (HAC) is a suitable primary biomaterial for reconstructing temporal bone defects.
  • Proper application of HAC restores temporal bone integrity and effectively eliminates cerebrospinal fluid leaks.
  • HAC offers a reliable solution for complex temporal bone reconstruction, minimizing postoperative complications.
