Endoscopic revision surgery for ossicular chain reconstruction: intraoperative findings and functional outcomes.

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
purposeTo report the intraoperative observations and hearing outcomes in patients undergoing endoscopic revision ossiculoplasty.
methodsA retrospective cohort of patients who had undergone revision ossiculoplasty were enrolled in this study. Intraoperative findings were documented. Follow-up visits were scheduled from 3 to 12 months post-surgery to assess hearing levels and record any potential complications.
resultsBetween April 2020 and May 2023, a total of 26 cases were enrolled, with 11 male patients represented. The mean age of the patients was 40.5 ± 9.4 years, ranging from 18 to 66 years. During the revision surgeries, various intraoperative findings were noted, including adhesive tissues affecting the activity of ossicular chain (observed in 37.0% of cases), tympanosclerosis of the ossicular chain (also in 37.0% of cases), dislocation of ossicular prosthesis (33.3%), erosion of the ossicular chain (33.3%), and identified cholesteatoma (11.1%). In terms of hearing outcomes, a significant improvement was observed. Overall, only 37.0% of patients achieved an air-bone gap of 20 dB or less, indicating the inferior outcome in revision ossiculoplasty.
conclusionsThis study highlight the role of inflammatory responses (adhesion, tympanosclerosis), stapes erosion, and prosthesis dislocation, as contributing factors to the failure of primary tympanoplasty. Endoscopic revision ossiculoplasty emerges as a reliable and effective approach.
