Revision stapedectomy: incus erosion and dislocated prosthesis

Revision stapedectomy

A case of Dr. Robert Vincent

In this case uploaded to the surgery app SurgSchool, we explore a surgery performed by the prestigious otologist Dr. Robert Vincent of the Causse Ear Clinic in Béziers, France. This revision stapedectomy offers us a unique insight into the complexities and key decisions in the surgical management of otosclerosis.

Context of the case

Dr. Vincent was faced with a stapedectomy revision case on the right ear. The previous surgery had yielded satisfactory results, but the patient presented sudden hearing loss months later due to dislocation of the prosthesis and partial erosion of the incus. This scenario underscores the challenges inherent in revision surgeries in otology.

Surgical approach

Dr. Vincent opted for an innovative and careful solution:

  1. Anvil Evaluation: Despite partial erosion, the anvil was functional and could be reused, avoiding the need for more invasive reconstructions.
  2. Prosthesis selection: A new prosthesis with a smaller loop was used, adapting to the altered anatomy of the incus and ensuring secure placement.
  3. Use of vein graft: The original vein graft remained intact and functional, which facilitated coverage of the round window and the new fenestration performed during surgery.

Detailed technique

The intervention stood out for its technical precision:

  • Careful measurement: Dr. Vincent measured the distance between the incus and the fenestration to select a prosthesis of the appropriate length (4,75 mm).
  • Precise crimping: The two-hook technique was used to close the loop of the prosthesis around the incus, ensuring a firm and stable fit.
  • Restoration of anatomy: The prosthesis was carefully positioned and mobility from the hammer was checked, achieving optimal sound transmission.

Reflections from Dr. Vincent

Dr. Vincent shared his experience and surgical preferences:

  • Avoids the use of cement to reconstruct the partially eroded incus, preferring techniques that preserve the original structure of the middle ear.
  • He stressed the importance of adjusting the choice of prosthesis according to the specific anatomical situation of each case.

Results

The procedure was completed successfully, restoring middle ear functionality and minimizing the risk of future complications. Dr. Vincent closed the intervention by thanking the spectators and emphasizing the Importance of sharing complex cases to foster learning in the medical community.
