Bilateral Endoscopic Type 1 Tympanoplasty in a Single Session: Functional and Clinical Outcomes.
Article in Turkish archives of otorhinolaryngology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: This study aims to evaluate the functional and clinical outcomes of single-session bilateral endoscopic type 1 tympanoplasty, with a focus on postoperative (post-op) hearing improvement and graft success rates in patients with chronic otitis media and tympanic membrane perforations. Methods: Fifteen patients (30 ears) with bilateral dry tympanic membrane perforations underwent trans-canal endoscopic type 1 tympanoplasty using a tragal perichondrium graft. Preoperative (pre-op) and post-op audiometric data, including pure-tone averages (PTAs) and air-bone gap (ABG) measurements at various frequencies, were collected and analyzed. Results: Functional success was defined as a post-op ABG <20 dB and PTA level improvements, while clinical success was determined by the presence of an intact tympanic membrane graft. The mean pre-op ABG significantly decreased post-oply in both ears, with an average ABG improvement of 25.00±7.32 dB at 500 Hz in the right ear and 18.00±8.41 dB in the left ear. The post-op PTA demonstrated an average gain of 27.00±7.51 dB in the right ear and 29.33±6.23 dB in the left ear. The functional success rate, defined as a post-op ABG <20 dB, was 93.33%, while clinical success, based on graft integrity, was also 93.33%. Conclusion: Single-session bilateral endoscopic tympanoplasty is a safe and effective procedure with high functional and clinical success rates. It leads to significant hearing improvement and has minimal post-op complications.
