Patient-Reported Outcomes of Palatopharyngeal Surgery Without Tonsillectomy: A Meta-Analysis.
Synthesis in The Laryngoscope, 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
objectiveTo compare patient-reported outcome measures (PROMs) across different palatopharyngeal surgical modifications without tonsillectomy for snoring and obstructive sleep apnea (OSA). DATA SOURCES: MEDLINE, Embase, Web of Science, ClinicalTrials, CINAHL, Cochrane Library, ICTRP. REVIEW
methodsWe conducted a systematic review and meta-analysis, including original studies of adult patients undergoing palatopharyngeal surgery without tonsillectomy for snoring and OSA. To reduce confounding, we excluded tonsillectomy, as tonsil size is a major predictor of outcome. Primary PROMs included changes in daytime sleepiness, as measured by the Epworth Sleepiness Scale (ESS), and snoring intensity, assessed on a visual analog scale, analyzed by surgical technique using random-effects models.
resultsFifty-five studies with 1815 patients were included. Overall, palatopharyngeal surgery without tonsillectomy reduced ESS by a mean of 3.3 points (95% CI, 2.7 to 3.9) and snoring intensity by 4.1 points (95% CI, 3.7 to 4.6). Among surgical techniques, suture palatopharyngoplasty, muscle relocation, cold-steel techniques, and powered instruments showed the largest reductions in both daytime sleepiness and snoring. Meta-regression analyses showed no evidence for declining treatment effectiveness with longer follow-up durations for both PROMs. Heterogeneity across studies was considerable, with a moderate overall risk of bias.
conclusionPalatopharyngeal surgery without tonsillectomy effectively improves patient-reported daytime sleepiness and snoring intensity, with outcomes varying by surgical techniques. Suture palatopharyngoplasty, muscle relocation, cold-steel techniques, and the use of powered instruments appear to be most effective in improving PROMs. These results inform surgical planning and counseling in patients seeking surgical treatment for snoring and daytime sleepiness.
