External Carotid Artery Ligation Versus Selective Artery Ligation in Transoral Surgery for Oropharyngeal Cancer.

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
objectiveProphylactic ligation of the external carotid artery (ECA) during oropharyngeal squamous cell carcinoma (OPSCC) resection is known to reduce severe postoperative oropharyngeal bleeding events, however, there is limited research on whether bleed rates vary between selective ligation of individual vessels or total ligation of the ECA. This study assesses outcomes related to total versus selective ligation of the ECA in patients who underwent transoral resection for OPSCC of the base of tongue or palatine tonsils. STUDY
designRetrospective review.
settingPatients who underwent OPSCC resection of the base of tongue or palatine tonsils at a single institution between October 2019 and September 2023.
methodsBleeding events within 30 days of surgery from the oropharyngeal surgical site were analyzed as well as other potential complications including stroke. Descriptive statistics and Fisher's exact test or χ
resultsOf 140 patients, 51 underwent base of tongue resection, and 89 had tonsillar resection. Total ECA ligation was performed in 56 patients, while 80 had selective ligation. There was no significant difference in oropharyngeal bleeding between the 2 groups (total 3.8% vs selective 3.7% P > .05). One patient in the total ECA ligation group had a stroke after resection (1.9%). On multivariate analysis, age (P = .024) and radiation exposure (P = .011) were found to be significant risk factors for hemorrhage.
conclusionSelective ligation of external carotid vessels versus total ligation of the ECA shows similar rates of oropharyngeal bleeding without any significant risk of stroke.
