Insights
For pediatric posterior fossa surgery, both sitting and prone positions are safe for suboccipital craniotomies. This study found no significant differences in complications or outcomes for pilocytic astrocytoma patients.
Area of Science:
- Neurosurgery
- Pediatric Oncology
Background:
- Suboccipital craniotomy for infratentorial access presents a choice between sitting and prone positions.
- Limited comparative data exists on complications and outcomes, particularly in pediatric populations.
Purpose of the Study:
- To compare intraoperative and postoperative complications and neurological outcomes in pediatric patients with pilocytic astrocytoma.
- Evaluate the safety and efficacy of sitting versus prone positioning for posterior cranial fossa surgery.
Main Methods:
- Retrospective analysis of 30 consecutive pediatric patients undergoing surgery for cerebellar pilocytic astrocytoma.
- Data collected from 1999 to 2017, including preoperative, intraoperative, and postoperative parameters.
Main Results:
- No statistically significant differences were observed between the sitting and prone position groups.
- Preoperative, intraoperative, and postoperative data showed similar profiles for both positions.
- Neurological status at last follow-up was comparable between the two groups.
Conclusions:
- Both sitting and prone positions are deemed safe for suboccipital craniotomies in pediatric patients.
- Further research is recommended to investigate positional differences for other pediatric brain tumors like medulloblastomas and ependymomas.
Purpose:
The choice between sitting and prone position to access the infratentorial space in a suboccipital craniotomy is still a matter of debate. The comparisons in terms of complications and outcome of both positions are scarce, and the pediatric population is indeed more infrequent in these in scientific reviews. In this paper, we assess intraoperative and postoperative complications and neurological outcome in pediatric patients undergoing posterior cranial fossa surgery for pilocytic astrocytoma in sitting and prone position respectively.
Methods:
We retrospectively analyzed 30 consecutive patients undergoing surgery for cerebellar pilocytic astrocytoma at the two neurosurgical units referring to the University of Padova Medical School from 1999 to 2017. Preoperative, intraoperative, and postoperative data were retrieved from our medical archives.
Results:
The statistical analysis did not show any differences between the two groups in terms of preoperative, intraoperative, and postoperative data. The neurological status at last follow-up was similar in both groups of patients.
Conclusions:
Our results suggest that both sitting and prone position can be considered safe in suboccipital craniotomies. Further studies are needed to show if there are possible differences between these positions for other frequent pediatric tumors such as medulloblastomas and ependymomas.
