Pyriform sinus injury in thyroidectomy: the unknown complicating the known.
Article in Annals of the Royal College of Surgeons of England, 2023. 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
Thyroidectomy is a common procedural skill in the armamentarium of an otolaryngologist but has its own set of complications. The more common complications are hypocalcaemia, recurrent laryngeal nerve palsy, injury to the external branch of the superior laryngeal nerve, postoperative bleeding, wound infection and, rarely, thyroid storm. High pyriform sinus injury during hemithyroidectomy is extremely rare, with this report being only the second reported case in the literature. A 61-year-old man presented with complaints of right-sided neck swelling. The patient had a 10cm × 8cm sized swelling in the anterior neck on examination. A contrast-enhanced computed tomography scan revealed a heterogeneously enhancing mass lesion involving the right lobe of the thyroid and isthmus with multiple nodules. The patient underwent right hemithyroidectomy with no intraoperative complications. The histopathology report describes a papillary thyroid carcinoma (cT3 N0 M0) with the presence of angioinvasion. On the fifth postoperative day, the patient complained of neck pain, suture site swelling and a change of voice. A volume of 50ml of whitish purulent fluid was evacuated. A laryngeal exam revealed restriction in mobility of the right vocal cord. The oesophagogram revealed the iatrogenic injury to the hypopharynx. The oesophageal leak gradually resolved after 6 weeks, as evidenced by multiple contrast oesophagogram, without any need for surgical intervention. We theorise that, while operating on long-standing monster thyroids, extra care should be given while dissecting in the tracheoesophageal groove as the stretched mucosa, an extracapsular extension of disease and lymphovascular invasion can all jeopardise the underlying structures.
