Efficacy of Platelet-Rich Plasma in Post-Tonsillectomy Wound Healing and Pain Management: A Randomized Controlled Study.
Trial report in Clinical otolaryngology : official journal of ENT-UK ; official journal of Netherlands Society for Oto-Rhino-Laryngology & Cervico-Facial 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
backgroundTonsillectomy is one of the most common surgical procedures in otolaryngology, but the healing process remains unknown in individual patients. Several interventions, including platelet-rich plasma, have been investigated to improve healing and pain control due to their regenerative properties.
objectiveTo assess the effect of platelet-rich plasma injection during tonsillectomy on postoperative results especially on epithelization stage and postoperative pain.
methodA prospective randomized controlled trial was conducted between January 2023 and December 2024, including 19 patients with platelet-rich plasma randomly injected in one of the fossae [treatment group] and normal saline in the other fossa [control group]. The endpoints were the epithelialization stage and pain score on days 1-7 after tonsillectomy.
resultsThere were no statistically significant differences between groups in the postoperative epithelization stage. At the treatment sites, grade III wound epithelization was 21.1%, compared with the control site, where none had grade III wound epithelization. The p-values for wound epithelization (0.903) and pain score (0.222) indicate no difference between groups. Both groups' pain scores improved over time (p < 0.001).
conclusionsIntraoperative injection of platelet-rich plasma into the tonsillar beds was effective in stimulating tonsillar wound healing. Because of its properties, the treatment group appeared to have faster wound recovery than the control group. However, the differences were not statistically significant. Further studies with larger sample sizes are warranted to elucidate the potential benefits of platelet-rich plasma in post-tonsillectomy healing.
