CT and MR Imaging Appearance of the Pedicled Submandibular Gland Flap: A Potential Imaging Pitfall in the Posttreatment Head and Neck.

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
Pedicled locoregional submandibular gland reconstruction flaps are increasingly used in oncologic head and neck surgery and have unique imaging characteristics that can mimic locally recurrent tumor. In this clinical report, 23 posttreatment imaging studies were evaluated in 19 patients who had undergone submandibular gland flap reconstructions after resection of a primary head and neck tumor. Submandibular gland flaps were most commonly mobilized into the parapharyngeal space or parotid bed, with others located inferior to the mandibular body and within marginal mandibulectomy defects. The original shape of the gland was typically not preserved. Identifying the submandibular gland hilum, vascular pedicle, glandular texture, and absence of submandibular gland in the orthotopic location was most useful in recognizing a flap. The interpreting radiologist must be familiar with the unique submandibular gland flap imaging characteristics to accurately differentiate normal postoperative appearance and recurrent tumor.
