Early trifurcation of the facial artery including a dedicated buccinator branch: anatomical and surgical implications.

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
Variations in the branching pattern of the facial artery may affect the planning and outcome of reconstructive and aesthetic procedures in the midface. Here, we report a rare anatomical variant in which the facial artery trifurcates early into three distinct branches, including a novel buccinator branch. In January 2025, the right-sided facial artery of a 67-year-old male Caucasian cadaver, injected with colored acrylic resins, was dissected at the ICLO Teaching and Research Center (Verona, Italy). Following identification of the external carotid artery, the facial artery was traced via an oblique submandibular approach. Branching patterns were documented through digital photography and schematic illustration. Instead of the classical singular course, the facial artery formed a common trunk that, 2 cm distal to its origin, trifurcated within a 1 cm span along the inferior mandibular margin. The anteromedial branch followed the standard facial artery trajectory; the posterolateral (premasseteric) branch supplied the masseteric region; and the central (buccinator) branch penetrated the buccinator fascia, arborizing extensively within the muscle belly. This buccinator branch exhibited a markedly dense microvascular network not previously described. This variant expands the known spectrum of facial arterial anatomy. While the direct clinical impact of a single observation remains limited, awareness of such configurations may be relevant in selected surgical contexts, particularly in flap planning and in procedures involving the buccal region. Unlike the classical buccal artery arising from the internal maxillary system, this branch originated directly from the facial artery and appeared to provide predominant intramuscular vascularization of the buccinator. Further bilateral cadaveric and imaging studies are necessary to determine the prevalence and clinical relevance of this and related anatomical configurations.
