Case Report: Use of submental artery perforator flap for reconstructing defects following sinonasal tumor resection.
Article in Frontiers in oncology, 2025. 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
Background: Sinonasal malignancies (SNMs) invading orbital and maxillofacial structures require complex reconstructive techniques. The submental artery perforator flap (SMAPF) provides a promising reconstructive option due to its vascular reliability and adaptability. Methods: A retrospective study reviewed three patients treated between December 2021 and November 2022 with radical resection of sinonasal malignancies, including orbital content removal. All patients underwent immediate reconstruction using an extended-pedicle SMAPF. The flap pedicle was elongated via microsurgical dissection under 2.5× magnification. Postoperative evaluations were conducted at 1, 3, and 6 months using nasal endoscopy and CT imaging. Results: All flaps survived without vascular compromise. No local recurrence or distant metastasis was observed. Functional and aesthetic outcomes were favorable, with no major complications reported. Conclusions: The extended pedicled SMAPF is a reliable and effective option for one-stage reconstruction of complex orbital and maxillofacial defects following sinonasal malignancy resection. It provides stable vascular support, and functional and aesthetic outcomes meet clinical expectations.
