Case Report: Partial resection of lingual ectopic thyroid using an electrohook under laryngoscopic guidance.
Article in Frontiers in surgery, 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
Introduction: Lingual thyroid is a rare ectopic thyroid disorder, with an incidence of 1 in 100,000-300,000. Surgical treatment options include transoral robotic surgery, transoral laser microsurgery, and coblation; however, these require expensive equipment, which may limit accessibility. We report a case that was successfully treated using an electrohook, a universally available and cost-effective alternative. Patient concerns: A 56-year-old woman presented with a 10-year history of foreign body sensation and dysphagia, which had recently worsened and was significantly affecting her quality of life, prompting her to seek medical attention. Diagnosis: Based on electronic laryngoscopy revealing a mass at the tongue base, elevated thyroid-stimulating hormone (TSH) levels (40 μIU/mL), a reduced cervical thyroid on ultrasonography, and contrast-enhanced CT demonstrating a characteristic thyroid-like enhancement pattern, a diagnosis of lingual ectopic thyroid with hypothyroidism was made. Postoperative pathology confirmed well-differentiated ectopic thyroid tissue. Intervention and outcomes: The patient received preoperative levothyroxine (25 μg/day). Under general anesthesia, with laryngoscope support, a partial resection was performed using an electrohook, which enabled simultaneous cutting and hemostasis. The procedure lasted 45 min and was associated with minimal blood loss (20 mL). Postoperatively, she received antibiotics and continued thyroid hormone replacement therapy. Her symptoms resolved completely, and recovery was uneventful. At the 3-month follow-up, she remained asymptomatic, with normalized thyroid function (TSH 5.2 μIU/mL) and an improved quality of life. Conclusion: Electrohook resection under laryngoscopic guidance is a simple, cost-effective, and safe treatment for symptomatic lingual ectopic thyroid, particularly suitable for primary hospitals, and may improve treatment accessibility for this rare condition.
