  • Objective

    This study aimed to assess the impact of the scutum on oval window accessibility during stapedotomy surgery. Radio-clinical correlation was applied to determine the impact.

    Methods

    This was a prospective observational case-series study that included 127 candidates for stapedotomy surgery. The oval fossa was classified into two types according to the accessibility of the stapes footplate.

    Results

    Both study groups showed a statistically significant difference in pre-operative radiological length as the p value was less than 0.001. The Spearman correlation coefficient revealed that the intra-operative oval window fossa was only significantly related to the radiological scutum length because the p value was less than 0.001.

    Conclusion

    Our results revealed that the pre-operative radiological length can predict the intra-operative oval fossa type with high sensitivity and specificity. Patients with a pre-operative scutum length of less than 2.35 mm were predicted to have an easily accessible oval window without requiring intra-operative scutum curettage.
