[T-cartilage tympanoplasty for an open oval window]

Area of Science:

• Otolaryngology
• Biomedical Engineering
• Regenerative Medicine

Context:

• The stapes bone is crucial for hearing, transmitting sound vibrations to the inner ear.
• Damage or ossification of the stapes can lead to conductive hearing loss.
• Current prosthetic solutions may have limitations in fit and long-term stability.

Purpose:

• To describe a novel T-shaped cartilage graft designed to function as a stapes prosthesis.
• To evaluate the anatomical and functional implications of this cartilage graft in the oval window.

Summary:

• A T-shaped cartilage graft is proposed as a functional stapes replacement.
• The transverse portion of the T-shaped graft limits insertion depth into the vestibule.
• Connective tissue can be used to ensure a seal within the vestibule if needed.

Impact:

• This cartilage graft offers a potentially biocompatible and adaptable solution for stapes replacement surgery.
• The design may reduce risks associated with overinsertion and improve prosthetic stability.
• Further research could explore its long-term efficacy and integration in hearing restoration procedures.
