Ceravital revisited: lessons to be learned.

Area of Science:

• Otolaryngology
• Biomaterials Science
• Surgical Outcomes

Background:

• Ossiculoplasty is a surgical procedure to restore hearing by reconstructing the middle ear ossicular chain.
• Ceravital prostheses are synthetic materials used in ossiculoplasty.
• Long-term outcomes of Ceravital prostheses in ossiculoplasty require further investigation.

Purpose of the Study:

• To evaluate the long-term efficacy and complications of ossiculoplasty using Ceravital prostheses.
• To analyze the incidence and timing of prosthesis-related complications.

Main Methods:

• Retrospective case review of 25 patients undergoing ossiculoplasty with Ceravital prostheses.
• Mean follow-up duration of 6 years and 6 months.
• Assessment of hearing gain (air-bone gap) and prosthesis-related complications.

Main Results:

• Short-term hearing improvement: mean air-bone gap reduced from 43 dB to 24 dB.
• Long-term complications included prosthesis absorption (9 cases), slippage (4 cases), extrusion (3 cases), and tympanic membrane atelectasis (2 cases).
• Absorption was the most frequent long-term complication, with a mean onset time of 6 years and 4 months.

Conclusions:

• Ceravital prostheses are associated with a significant risk of late-onset absorption.
• The rate of absorption appears to increase over extended follow-up periods.
• Understanding these long-term complication patterns is crucial for patient selection and surgical technique optimization.
