Intraoral midline mandibulotomy to improve access for transoral robotic surgery (TORS) base of tongue resection in a retrognathic and microstomic patient.
Article in BMJ case reports, 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
A 74-year-old man was referred to a tertiary academic otolaryngology clinic for evaluation of a left-sided neck mass with unknown primary. Nuclear imaging modalities revealed a primary cancer located at the left tongue base. Further investigation revealed the tumour to be a p16 positive squamous cell cancer with metastatic spread to cervical lymph nodes of multiple levels. The patient was found on initial investigation to have microstomia and a retrognathic mandible, which are typically considered unsuitable for robotic surgery due to difficulties obtaining adequate exposure.The patient underwent bilateral neck dissection, followed by transoral robotic-assisted left base of tongue resection. A midline intraoral mandibulotomy was performed to improve robotic access. Following tumour resection, the mandible was repaired using open reduction with internal plate fixation. Postoperative occlusion was maintained, and the patient recovered well from mandibulotomy with none of the morbidity or cosmetic defects associated with a traditional lip-split approach.
