Bone cement effectively reconstructs the ossicular chain in chronic suppurative otitis media patients, significantly improving hearing. This ossicular reconstruction method shows no complications and offers a durable alternative to traditional grafts.

Area of Science:

  • Otolaryngology
  • Surgical Innovation
  • Hearing Restoration

Background:

  • Chronic suppurative otitis media frequently leads to incudostapedial disarticulation.
  • Traditional ossicular reconstruction methods, such as incus interposition grafts and partial ossicular prostheses (POPs), carry risks of migration and recurrent hearing loss.

Purpose of the Study:

  • To evaluate the efficacy and safety of using bone cement for ossicular reconstruction in patients with chronic suppurative otitis media.
  • To compare outcomes of bone cement ossiculoplasty with historical methods.

Main Methods:

  • A retrospective review of 264 patients with chronic suppurative otitis media who underwent mastoidectomy with tympanoplasty.
  • Eighty patients with incudostapedial disarticulation were reconstructed using incus interposition grafts (n=31), POPs (n=31), or bone cement (n=18).

  • Audiometric data pre- and post-intervention were analyzed, with follow-up ranging from 1 to 3 years.

    • Main Results:

    • Preoperative air-bone gaps averaged 33 dB, significantly improving to an average of 10 dB postoperatively.
    • Statistically significant hearing improvement was observed.
    • No complications or increase in conductive hearing loss were reported, and the bone cement showed no dissolution.

    Conclusions:

    • Bone cement ossiculoplasty is a safe and effective technique for reconstructing the ossicular chain in cases of incus-stapes disarticulation.
    • This method offers a natural restoration of ossicular integrity and presents an excellent alternative to existing reconstruction techniques.
    • The durability of bone cement reconstruction is supported by the absence of dissolution and persistent positive results during the follow-up period.
