The CO2 laser and microdrill (MD) showed no worsening in bone conduction for otosclerosis surgery. The Piezosurgery bone device (PZS) resulted in hearing loss and vertigo, necessitating further validation.

Area of Science:

  • Otolaryngology
  • Neurosurgery
  • Medical Devices

Background:

  • Otosclerosis is a condition causing abnormal bone growth in the ear, leading to hearing loss.
  • Stapedotomy is a surgical procedure to restore hearing by removing the stapes bone and replacing it with a prosthesis.
  • Choosing the right surgical instrument for stapedotomy is crucial for optimal patient outcomes.

Purpose of the Study:

  • To compare the efficacy and safety of three different devices for stapes footplate perforation during otosclerosis surgery.
  • To evaluate the impact of microdrill (MD), CO2 laser (CO2), and Piezosurgery bone device (PZS) on hearing outcomes and postoperative complications.

Main Methods:

  • A prospective, unblinded study involving 90 patients undergoing primary stapedotomy for otosclerosis.

  • Patients were divided into three groups, with each group undergoing stapedotomy using one of the three devices (MD, CO2, PZS).
  • Preoperative and postoperative audiometry (air-conduction and bone-conduction), intraoperative findings, and complications were assessed, with audiometry performed one month post-surgery.

    • Main Results:

    • Bone-conduction thresholds did not worsen with the microdrill (MD) or CO2 laser (CO2).
    • The CO2 laser group showed a trend towards a smaller residual air-bone gap and greater low-frequency gain.
    • Piezosurgery bone device (PZS) use was associated with a 10 dB bone-conduction loss at 4,000 Hz, reduced high-frequency gain, and a higher incidence of postoperative vertigo.

    Conclusions:

    • The CO2 laser appears to offer the best functional results in stapedotomy for otosclerosis, though not statistically superior to the standard microdrill (MD).
    • While Piezosurgery bone device (PZS) is surgically effective, it carries risks of high-frequency hearing deterioration and increased vertigo.
    • Further validation of Piezosurgery bone device parameters is recommended for safe clinical application.
