Total Ossiculoplasty : Advantages of Two-Point Stabilization Technique

الملخص EN

Objective.

Evaluate a porous polyethylene prosthesis with two-point stabilization in total ossiculoplasty.

This approach utilizes a lateral as well as a medial graft to stabilize a total ossicular prosthesis (TOP).

Study Design.

Retrospective cohort review of total ossiculoplasty.

Methods.

All patients who underwent total ossiculoplasty during the years 2004–2007 were included in the study group.

Only five patients (10%) had primary surgery whereas 45 (90%) underwent revision surgery.

Cartilage grafts covering the prosthesis (Sheehy, Xomed) laterally were used in all patients with areolar tissue being used for medial stabilization at the stapes footplate.

Follow-up examination and audiometrics were performed a mean of 8.1 months following surgery.

Results.

The percentage of patients closing their ABG to within 10 dB was 44% with 66% closing their ABG to within 20 dB.

The mean four-frequency hearing gain was 15.7 dB.

The mean postoperative ABG was 15.7 dB.

Conclusion.

Audiometric results following total ossiculoplasty surgery using two-point stabilization exceeded results from the otologic literature.

Proper two-point fixation with areolar tissue and stabilization utilizing cartilage were the keys to achieving a relatively high percentage of success in chronic ear disease in this sample.
