ABSTRACT

BACKGROUND:

The microscopic middle ear surgery involves a limited operating space and numerous important anatomical structures in which good visualization is crucial, as even a small amount of bleeding can greatly affect the clarity of surgical field. This study aims to investigate whether intravenous 1 g of tranexamic acid can improve surgical visualization and further shorten the operation time in microscopic middle ear surgery.

METHODS:

This study is a prospective, randomized, double-blind, controlled trial conducted from December 2021 to December 2022, enrolling patients who were scheduled for microscopic modified radical mastoidectomy due to chronic otitis media. In addition to standard techniques to optimize the surgical field, participants were randomized into the TXA (tranexamic acid) group (1 g diluted to 20 ml normal saline) and the control group (20 ml normal saline). The primary outcome was assessed based on the clarity of the surgical field using the Modena Bleeding Score. Secondary outcomes included operation time, the surgeon satisfaction with the visual clarity, postoperative 24 h coagulation parameters, and the incidence of adverse events. Student's t -test, χ2 test, and ANOVA of repeated measures were used for statistical analyses.

RESULTS:

A total of 28 patients were enrolled in each group using a 11 randomized allocation with similar demographic characteristics, including 24 male and 32 female individuals, and the mean age is 45.6±11.9 years. The surgical visualization in the TXA group was significantly better than that of the control group (2.29±0.46 vs. 2.89±0.31, P <0.001) as assessed by the Modena Bleeding Score. Furthermore, the TXA group demonstrated a shorter operation time compared to the control group (88.61±10.9 vs. 105.2±15.9, P <0.001) and higher surgeon satisfaction with surgical field (7.82±0.55 vs. 6.50±0.64, P <0.001). No statistically significant differences were found in postoperative coagulation parameters in the two groups. No TXA-related adverse events or complications occurred during the 12-month follow-up.

CONCLUSION:

Intravenous 1 g of TXA can further significantly improve the visual clarity in the microscopic middle ear surgery and shorten the operation time based on other standard measures implemented.
