Our experiences with revision stapedotomies: The role of periprosthetic
fibrosis formation in the development of unsatisfactory hearing results
after stapedotomy.
Abstract
KEY POINTS: - Our goal was to indentify the most common and most
influential postoperative reasons causing persistent ABG. Our focus was
concentrated on the mechanical dysfunctions in the middle ear, with
special regard to postoperative fibrosis formation. - Periprosthetic
adhesion formation was seen in 64% of the cases, and it was the primary
cause behind the unsatisfactory hearing result in 32% of all cases -
There was no significant difference in the level of persistent ABGs
across groups of fibrosis and surgical failure after primary surgery -
Periprosthetic fibrosis is the most common reason for compromised
audiological outcomes after stapedotomy, and has the same negative
effect on ABG development as any other surgical failure, while the
revision could be more challenging in these cases - The use of the most
atraumatic surgical technique and preservation of intact intratympanic
mucosa is a key factor during middle ear surgery.
