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 mieddle 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.
