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

backgroundHigh-definition, three-dimensional (3D) exoscopes are being used to perform a growing number of head and neck surgeries. However, the use of the 3D exoscope in parotid gland surgery has not been previously described. Our initial experience with the VITOM 3D exoscope in the surgical treatment of parotid gland tumors is detailed here.

methodsWe made a prospective study of patients with benign parotid gland tumors indicated for surgical resection. Between January and December 2018, patients were randomly assigned to undergo surgery assisted with the VITOM 3D system (n = 31) or an operating microscope (n = 40). Visualization quality (greater auricular nerve, digastric muscle, tragal pointer), operating time, conversion rates, and surgical outcomes were compared.

resultsA total of 71 patients underwent superficial (n = 18) or total parotidectomy (n = 53). No exoscope-related complications were observed. Five patients undergoing exoscope-guided deep lobe surgery required intraoperative conversion to a microscope. No differences were observed in the subjective quality of intraoperative visualization of key anatomical structures. However, a significantly higher percentage of patients in the exoscope group developed transient facial nerve paralysis (n = 9; 29% vs. n = 4, 10%).

conclusionsThese findings suggest that the VITOM 3D is a valid visualization tool for parotid gland surgery, comparable to the operating microscope but with higher resolution 3D visualization, an increased degree of freedom of movement, and better ergonomics. However, the high rate of transient nerve palsy, possibly related to decreased depth perception and the brief learning curve, merits further investigation.
