1 · What the graph read from it

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.

2 · The registry

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

backgroundExoscope has been used in otoneurologic surgery in several reports. However, most ear surgeries are performed using either microscope or endoscopy today. The purpose of this study is to present our subjective and objective experience of using this instrument in our institution.

methodsSixteen ears with different severity and condition in 15 consecutive patients were enrolled. A questionnaire with 12 questions was sent to different participants, including surgeons, residents, medical students, and scrub nurses in the operation room. The total score and average score of each item were calculated and analyzed.

resultsExclusive exoscopic operation was performed on 13 patients with 14 procedures. A combination of endoscopy-exoscope and microscope-exoscope was used in one patient, respectively. There were no complications. Hearing recovery or disease extirpation was achieved in most patients. Twenty participants in the operation room filled out the questionnaire. There was no significant difference between the different groups. High ratings were reported in terms of image quality, stereoscopic effects, magnification rate, and the same field of view as the surgeon. Worse ratings were reported in items related to limited working space, increase in eye strain by video observation, and focusing difficulty.

conclusionExoscopic ear surgery is feasible, safe, and effective in managing various otologic conditions involving external ear, middle ear, mastoid, and lateral skull base. Its high-definition image quality, stereoscopic effects, sufficient magnification, reliability and teaching value made it a potential instrument in general ear surgeries. Further improvements to current drawbacks can be anticipated.
