Improved Bone Conduction and Hearing Outcomes After Stapes Surgery for Otosclerosis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: To evaluate the improvement in bone conduction (BC) thresholds after stapes surgery for otosclerosis, compare the outcomes of surgical techniques, and analyze the short- and long-term results to inform treatment strategies. Methods: We retrospectively reviewed data from 173 patients (188 ears) who underwent total stapedectomy, partial stapedectomy, or stapedotomy for otosclerosis between 2009 and 2024. Medical histories, preoperative evaluations, and operative records were analyzed, focusing on pre- and postoperative pure-tone audiometry. Results: Postoperatively, mean thresholds improved by 20.3 dB for air conduction (AC) and 2.0 dB for BC, leading to a mean air-bone gap (ABG) of 18.3 dB. An ABG of less than 10 dB was achieved in 79 ears (42.0%), and full ABG closure (ABG ≤ 20 dB) was achieved in 145 ears (80.4%). Compared with the preoperative levels, the BC thresholds at 0.5, 1, and 2 kHz improved by 1.3, 3.7, and 4.9 dB, respectively. However, the 4-kHz BC threshold increased by 1.7 dB. Postoperative AC thresholds at 0.5-4 kHz decreased significantly by 27.1, 26.5, 18.3, and 9.2 dB, respectively ( Conclusion: Stapes surgery significantly improved BC thresholds at 0.5, 1, and 2 kHz in patients with otosclerosis, with resolution of the CN at 2 kHz, indicating correction of the CHL. Although a slight increase in the BC threshold was observed at 4 kHz, the overall AC threshold improvement and ABG closure were substantial. These findings highlight the clinical relevance of the postoperative BC threshold dynamics.
