Feasibility and role of the lateral arm free flap following pull-through oropharyngectomy for tonsillar carcinoma: a clinical analysis.
Article in BMC surgery, 2026. 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
backgroundThe mandible-preserving pull-through oropharyngectomy (MPPO) offers a less morbid alternative for traditional mandibular swing approach, particularly for tonsillar carcinoma. The lateral arm free flap (LAFF) is a versatile and reliable option for soft tissue reconstruction, particularly suitable for small-to-medium-sized defects of the oropharyngeal region.
methodsThis study is a retrospective study including data from 23 patients with tonsil carcinoma, diagnosed and treated at a tertiary referral center. The QLQ-C30, QLQ-H&N35 inventories, were administered at three different timepoints: At 1-month, 3-month and 6-month postoperatively. The flap-related data and the quality-of-life data were collected and presented in a descriptive manner.
resultsMost flaps survived (95.65%), one case of necrosis occurred, while 8.70% patients experienced recipient-site bleeding, 4.35% and 21.74% of patients experienced systemic complications such as pulmonary embolism and hypoalbuminemia respectively. Following surgery, all patients successfully underwent decannulation (average 28.22 days) and NGT extraction (average 12.09 days). Among ten patients with complete QoL data, global QoL and most functional domains improved over six months, with resolution of fatigue, insomnia, speech, social, and cough issues but a worsening of xerostomia.
conclusionThe LAFF reconstruction in tonsil carcinoma patients with MPPO surgery demonstrates favorable postoperative outcomes and QoL results in our institution.
trial registrationThis study was conducted in accordance with the Declaration of Helsinki and was approved by the Institutional Review Board of West China Hospital, Sichuan University (Approval No. 2025‑1235; Date: 1 February 2025). Written informed consent was obtained from all participants. As a retrospective analysis of a standard reconstructive technique, this study did not require prospective trial registration.
