Insights
Early cranioplasty after decompressive craniectomy for brain injury improves neurological outcomes. Shorter delays (<86 days) to cranioplasty correlate with better functional recovery compared to longer delays.
Area of Science:
- Neurosurgery
- Neurology
- Rehabilitation Medicine
Background:
- Decompressive craniectomy effectively treats intracranial hypertension after acute brain injury.
- Optimal timing for subsequent cranioplasty remains unclear, particularly in the sub-acute phase.
- Cranioplasty restores skull integrity and may influence neurological recovery.
Purpose of the Study:
- To investigate the impact of cranioplasty timing on neurological outcomes in patients who underwent decompressive craniectomy.
- To identify factors influencing functional recovery following cranioplasty.
Main Methods:
- Single-center observational study of 147 patients undergoing decompressive craniectomy and cranioplasty.
- Retrospective analysis of prospectively collected weekly scores (Barthel-Index, Functional Independence Measure, Coma Remission Scale).
- Regression analysis to determine predictors of outcome.
Main Results:
- Patients with early cranioplasty (cranioplasty <86 days post-decompression) showed significantly better functional outcomes (Barthel-Index scores) than those with delayed cranioplasty (>85 days).
- Early cranioplasty group: 60 ± 29.5 BI points vs. late group: 25 ± 24.1 BI points (p < 0.01).
- Age, pre-operative Barthel-Index, and Coma Remission Scale scores were independent predictors of outcome. No significant difference in complication rates between early and late groups.
Conclusions:
- Early cranioplasty may enhance neurological and functional recovery in patients treated with decompressive craniectomy for intracranial hypertension.
- Timely cranioplasty is a crucial consideration in the neurorehabilitation pathway.
Primary Objective:
Decompressive craniectomy is an effective therapy to relieve intractable intracranial hypertension following acute brain injury. However, little is known about the optimal timing for cranioplasties in the sub-acute phase. The objective of the present study was to analyse the effect of cranioplasty timing on neurological outcomes.
Research Design:
Single-centre observational study.
Methods And Procedures:
One hundred and forty-seven consecutive patients with decompressive craniectomy and cranioplasty during the course of inpatient neurorehabilitation were identified by means of a retrospective hospital database search. This database contains the following prospectively-entered weekly scores: Barthel-Index (BI), Functional Independence Measure (FIM) and Coma Remission Scale (CRS). Additional clinical data were taken retrospectively from patient charts. Regression analysis was used to identify factors that influenced the end-of-rehabilitation outcome.
Main Outcomes And Results:
Patients with shorter delays to cranioplasty (<86 days) had a better functional outcome than patients with longer delays of >85 days (60 ± 29.5 versus 25 ± 24.1 BI points; p < 0.01, respectively). Age, pre-operative BI and CRS scores were additional independent outcome factors. Complication rates were not different between early and late cranioplasty groups.
Conclusions:
Patients with decompressive craniectomy for management of intracranial hypertension may benefit from early cranioplasty.
