[Ultrasound glossopharyngeal block for oropharyngeal pain management in cancer patients].
Observational study in Revista medica del Instituto Mexicano del Seguro Social, 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
Background: Oropharyngeal pain due to oral mucositis and base of tongue tumors is a frequent and highly disabling condition that significantly impacts quality of life. Its management is often complex, involving nociceptive, inflammatory, and neuropathic mechanisms with limited response to conventional therapy. Ultrasound-guided glossopharyngeal nerve block has emerged as a safe and effective alternative to improve analgesia. Objective: To evaluate pain control using ultrasound-guided glossopharyngeal nerve block in patients with oral mucositis or base of tongue tumors. Material and methods: A prospective observational study was conducted in a tertiary care hospital, fifteen cancer patients are inlcuded with severe oropharyngeal pain associated with mucositis or base of tongue tumors. All patients underwent ultrasound-guided glossopharyngeal nerve block with local anesthetic and corticosteroid. Pain was assessed using the ENA and FLACC scales, along with evaluation of oral intake tolerance, adjuvant analgesic use, and complications. Results: Pain intensity significantly decreased from 9 to 0 at 30 minutes (p < 0.05) and remained low at 7 days. One minor complication (10%) was reported. The procedure suggested to be safe and effective. Conclusions: Ultrasound-guided glossopharyngeal nerve block is a minimally invasive, is potentially safe, and effective technique for managing oropharyngeal pain in cancer patients.
