Long-Term Hearing Results After Ossiculoplasty

Area of Science:

• Otolaryngology
• Audiology
• Surgical Outcomes Research

Background:

• Ossiculoplasty is a surgical procedure to restore hearing by reconstructing the middle ear ossicles.
• Predicting long-term hearing results after ossiculoplasty is crucial for patient management and expectations.
• The OOPS index is a novel tool proposed for assessing surgical risk and outcomes in otologic procedures.

Purpose of the Study:

• To evaluate the predictive capability of the OOPS index for long-term hearing outcomes following ossiculoplasty.
• To assess the correlation between OOPS index scores and audiological results in adult and pediatric patients.

Main Methods:

• A retrospective chart review of adult and pediatric patients who underwent ossiculoplasty with cartilage tympanoplasty was conducted.
• Pure-tone average air-bone gap (PTA-ABG) was measured at short-term (60 days to 1 year) and long-term (≥5 years) post-surgery.
• Spearman's rank-order correlation was used to analyze the relationship between OOPS index scores and PTA-ABG.

Main Results:

• No significant difference in short-term or long-term hearing results was observed between adult and pediatric patients.
• A strong positive correlation was found between OOPS index scores and both short-term (ρ=0.983, p<0.001) and long-term (ρ=0.950, p<0.001) PTA-ABG.
• The OOPS index demonstrated a high degree of accuracy in predicting hearing outcomes.

Conclusions:

• The OOPS index is a reliable tool for accurately prognosticating hearing outcomes in both adult and pediatric patients undergoing ossiculoplasty.
• This predictive capability extends to both short-term and long-term hearing results, aiding in surgical planning and patient counseling.
