Optimum Tension for Partial Ossicular Replacement Prosthesis Reconstruction in the Human Middle Ear
TL;DR: Hearing results from ossiculoplasty are unpredictable because the mechanical functioning of partial ossicular replacement prostheses from the stapes head to the eardrum will be affected by the tension that they are placed under.

Comparison of the mechanical performance of ossiculoplasty using a prosthetic malleus-to-stapes head with a tympanic membrane-to-stapes head assembly in a human cadaveric middle ear model.
TL;DR: Tension has a significant effect on prosthesis function and generally result in better transmission of vibrations to the stapes footplate than tympanic membrane assembly to theStapes head type prostheses.

TL;DR: In this article, a self-retaining bone conduction hearing device has been proposed for non-surgical implantation in a recipient's ear canal, which eliminates the dependency on acoustic stimulation, enabling the hearing device of the present invention to address a wider range of sound frequencies in conductive hearing loss.

How do cartilage and other material overlay over a prosthesis affect its vibration transmission properties in ossiculoplasty
TL;DR: The effects of vibration transmission to the footplate of inserting cartilage of varying sizes, and materials of varying rigidities were examined, with smaller cartilage covers performing best and larger cartilage sizes performing worse.

The importance of an extended preoperative trial of BAHA in unilateral sensorineural hearing loss: a prospective cohort study
TL;DR: In this paper, the influence of an extended preoperative trial of bone-anchored hearing aid (BAHA) and headband on the decision to proceed with surgery in cases of unilateral sensorineural hearing loss is studied.
