Endoscopic-Assisted Mandibular Angle Revision Using Patient-Specific PEEK Implants: Surgical Accuracy and Aesthetic Outcomes in Over-Resected Mandibles.
Article in Aesthetic plastic surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundMandibular angle osteotomy (MAO) is a popular procedure to improve facial aesthetics, however, over-resection of the mandibular angle can lead to both functional and aesthetic challenges. Precision is essential in restoring these over-resected mandibles to achieve balanced outcomes. Polyetheretherketone (PEEK) implants offer biocompatibility, durability, and customization potential, making them valuable for achieving precise and predictable results. This study examines the efficacy of PEEK patient-specific implants (PSIs) in endoscopic-assisted mandibular angle revision (MAR) surgery, assessing improvements in surgical accuracy and aesthetic outcomes.
methodsWe retrospectively analyzed 24 patients (39 mandibles) who underwent MAR from January 2019 to December 2023. Surgical accuracy was measured by comparing planned and achieved PSI positions using root mean square error (RMSE) and maximum deviation (MaxD). Patient satisfaction was assessed using the FACE-Q questionnaire, administered preoperatively and at least six months postoperatively, with correlations drawn between implant fit accuracy and FACE-Q scores changes.
resultsThe average RMSE ranged from 0.1166 to 0.3149 mm, with 96% of PSIs showing deviations under 0.3 mm. FACE-Q scores for lower facial appearance and psychological well-being improved significantly, form 42.50 ± 5.28 to 56.08 ± 4.58 and 61.50±4.31 to 70.58 ± 6.46, respectively. A strong negative correlation was observed between implant fit accuracy (RMSE, MaxD) and FACE-Q score improvements related to appearance.
conclusionsEndoscopic-assisted MAR with PEEK PSIs offers precise correction and significant aesthetic improvements for patients with over-resected mandibles. This technique demonstrated high surgical accuracy and favorable patient-reported outcomes. Future studies on a larger scale are recommended to validate these findings.
