Preliminary Feasibility Implementation of Post-Decompressive Craniectomy 3D-Printed Externally Applied Cranial Orthosis (PEACO) During Inpatient Rehabilitation: A Retrospective Cohort Study Reporting Short-Term Tolerability and Patient/Caregiver-Reported Feedback

A minimally monitored clinical protocol demonstrated preliminary short-term feasibility and tolerability: 18/23 (78.3%) fitted patients were confirmed compliant, with 18/20 (90%) respondent compliance and three patients of unknown status, without serious adverse events. Longer follow-up studies are needed to assess sustained compliance throughout the pre-cranioplasty period. Future research should standardise materials and outcome measures to inform clinical practice guidelines. Background/Objectives: 3D-printed externally applied cranial orthosis (PEACO) represents an emerging solution for temporary cranial protection, though evidence remains limited regarding real-world implementation using minimally monitored clinical protocols.
