Stored bone allografts from long bone cortices show excellent anatomical success (97%) for tympano-ossicular chain reconstruction. Functional outcomes are comparable to bioceramics, offering a viable option in otologic surgery.

Area of Science:

  • Otolaryngology
  • Orthopedic Surgery
  • Biomaterials Science

Background:

  • Reconstruction of the tympano-ossicular chain is crucial for hearing restoration.
  • Allografts offer a potential solution for ossicular reconstruction.
  • Stored bone grafts require evaluation for efficacy and safety.

Purpose of the Study:

  • To evaluate the use of stored bone allografts for tympano-ossicular chain reconstruction.
  • To assess the anatomical and functional outcomes of these grafts.
  • To explore additional applications of bone allografts in otology.

Main Methods:

  • Allografts were shaped from the cortices of long bones.
  • Grafts were used for ossiculoplasty in patients.
  • Materials and methods of graft preparation and implantation were detailed.

Main Results:

  • Excellent anatomical results were achieved in 97% of cases.
  • Functional results were comparable to those obtained with bioceramics.
  • Bone allografts demonstrated utility in reconstructing large temporal bone defects.

Conclusions:

  • Stored bone allografts are effective for tympano-ossicular reconstruction.
  • These allografts provide satisfactory functional outcomes in otologic surgery.
  • Bone allografts have broader applications in reconstructing bony defects in the temporal bone.
