Transoral robotic surgery using CO
Article in Lasers in medical science, 2026. 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
purposeTransoral robotic surgery (TORS) is an established surgical approach for oropharyngeal squamous cell carcinoma (OPSCC). Carbon dioxide (CO₂) laser offers high cutting precision and minimal collateral thermal injury, yet its use in TORS remains underreported. The purpose of this study is therefore to describe the first UK case series detailing the use of CO₂ laser via hollow waveguide in TORS.
methodsEight patients (six male, two female; mean age 60 years) presenting with either left tonsillar (seven cases) or right tongue base (one case) OPSCC underwent primary TORS resection with CO₂ laser at a tertiary UK head and neck centre between October 2020 and May 2024. Cases were selected based on tumour stage, anatomical suitability and patient preference. The CO₂ laser (SmartXide Trio, 3-10 W, ultra-pulse mode) was delivered via hollow waveguide mounted on one of the arms of the Da Vinci robotic system. Outcome measures included histological margin status, peri- and postoperative complications, swallowing function, and hospital length of stay.
resultsAll tumours were completely excised; two of the eight had close margins on the primary specimen but were clear on additional sampling. No intraoperative complications occurred, and all procedures were completed without conversion. All patients resumed oral intake without nasogastric feeding. Mean hospital stay was 2.75 days, with no airway compromise, catastrophic bleeding, or significant swallowing dysfunction.
conclusionCO₂ laser dissection in TORS for OPSCC represents a viable surgical approach with acceptable postoperative functional outcomes and may possibly demonstrate reduced thermal injury compared with monopolar electrocautery.
