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

backgroundFollowing promising initial results of the robotic-assisted extended "Sistrunk" approach (RESA) that uses a submental incision to hypopharyngeal and laryngeal tumors, bypassing the base of tongue, we report its further development: submental approach robotic-assisted neck dissection (SARAND), intended to enable bilateral neck dissections.

methodsBilateral neck dissections (levels I-IV) were performed on three cadavers using both multiport and single-port robotic platforms.

resultsWe demonstrate the feasibility of performing levels I-IV dissections through a single submental incision with both robotic platforms. A central working space was established over the hyoid bone, and boom rotation enabled optimal access to all neck levels from I to IV.

conclusionSARAND appears to be a promising minimally invasive technique for both unilateral and bilateral neck dissection. It offers the potential to reduce neck morbidity compared to conventional approaches. Additionally, it potentially enables neck dissection and primary tumor excision via a median pharyngotomy during the same procedure.
