Summary
Long-term hearing loss after stapes surgery can occur. Causes may include piston displacement and bone regrowth in the platinotomy hole, affecting hearing outcomes over time.
Area of Science:
- Otolaryngology
- Neurosurgery
- Audiology
Background:
- Stapes surgery is a common procedure for hearing loss.
- Long-term hearing deterioration can occur post-surgery.
- Investigating causes of progressive hearing loss is crucial.
Purpose of the Study:
- To investigate the causes of long-term hearing loss progression after stapes surgery.
- To identify factors contributing to decreased hearing outcomes over 5 years post-operation.
Main Methods:
- Retrospective study of 30 ears from 23 patients undergoing stapes surgery (2001-2021).
- Analysis of air conduction (AC) and bone conduction (BC) thresholds, and air-bone gap (ABG) at 6 months and 5 years post-surgery.
- Classification into groups based on hearing changes and examination of contributing factors and reoperations.
Main Results:
- AC thresholds improved significantly at 6 months and 5 years post-surgery (p < 0.01).
- BC thresholds showed no significant change (p > 0.05).
- 10% of patients experienced an increase in AC threshold and ABG (≥10 dB) by 5 years post-surgery.
Conclusions:
- Progressive hearing loss occurred in 10% of patients long-term after stapes surgery.
- Piston displacement and platinotomy hole closure by bone regrowth are potential causes.
- These factors may explain late-onset hearing deterioration following stapes surgery.
