Primary endoscopic stapedotomy using 3 mm nasal endoscope: Audiologic and clinical outcomes.
Article in Journal of otology, 2020. 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
objectiveTo report the use of a 3 mm rigid nasal endoscope in primary endoscopic stapedotomy and clinical and audiological outcomes. MATERIALS AND
methodsThirty patients diagnosed with primary otosclerosis underwent endoscopic stapedotomy that was performed using a 3 mm nasal endoscope (Karl Storz). At 6 months follow-up, the patients were evaluated for intraoperative findings, postoperative hearing outcomes and complications.
resultsCanaloplasty was performed in 2 (6.66%) patients, and no curettage of the canal wall was required in 12 (40%) patients. Transposition of the chorda tympani nerve was conducted in 11 (36.66%) patients. The average duration of surgery was 36 min (range 31-65 min). The air-bone gap (ABG) was 35 dB (range 24-50 dB) preoperatively and 14.63 dB (range 9-20 dB) postoperatively (p = 0.00). At 6 months follow-up, <20 dB ABG was achieved in 93.33% of the patients. No major intraoperative/postoperative complications were detected.
conclusionA 3 mm rigid nasal endoscope can be effectively used in stapedotomy to obtain adequate audiological outcomes. It can be considered as a better alternative to the standard microscope or 4 mm endoscope in preserving the posterior canal wall and chorda tympani nerve while minimizing operative time without causing significant complications.
