Application of polyetheretherketone temporal muscle prostheses for temporal hollowing following cranioplasty.
Article in Frontiers in neurology, 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: Decompressive craniectomy is an effective intervention for refractory intracranial hypertension. However, subsequent cranioplasty, though technically less demanding, is associated with a non-negligible incidence of complications. Among these, temporal hollowing is a common yet frequently overlooked sequela that significantly compromises facial aesthetics and can lead to various psychosocial issues. Methods: Based on the pathophysiological mechanisms underlying temporal hollowing following cranioplasty and incorporating clinical experience from West China Hospital, Sichuan University, this study explores the application of 3D-printed polyetheretherketone (PEEK) temporal muscle prostheses for correcting temporal hollowing after 3D-printed PEEK cranioplasty. The approach involves precise measurement of the contralateral temporal muscle dimensions and volumetric assessment of the atrophied ipsilateral muscle to fabricate patient-specific 3D-printed PEEK implants. These customized prostheses are then surgically implanted in a secondary procedure to restore temporal contour symmetry. Conclusion: Temporal hollowing represents a frequent sequela of cranioplasty, arising from multifactorial mechanisms and often contributing to psychosocial challenges. The patient-specific 3D-printed PEEK temporal muscle prosthesis, developed based on contralateral temporal muscle metrics at West China Hospital, offers a precise and individualized solution for restoring temporal contour symmetry.
