Bone Flap Preservation in Subcutaneous Abdominal Pocket for Decompressive Craniectomy

Area of Science:

• Neurosurgery
• Pediatric Surgery

Background:

• Decompressive craniectomy involves removing a section of the skull to relieve pressure.
• Bone flap preservation is necessary for subsequent cranioplasty, restoring the skull defect.
• Pediatric patients present unique challenges for bone flap storage due to anatomical considerations.

Observation:

• Two pediatric cases utilized subcutaneous abdominal pocket preservation for bone flaps after decompressive craniectomy.
• In one case, the bone flap was divided; in the other, it remained intact.
• The abdominal pocket provided adequate storage space, particularly useful in pediatric anatomy.

Findings:

• Both cases demonstrated successful bone flap preservation using the in vivo abdominal pocket technique.
• No complications were reported with the preserved bone flaps in either case.
• This method offers a viable alternative to traditional cryopreservation for pediatric bone flaps.

Implications:

• Subcutaneous abdominal pocket preservation is a practical and effective technique for pediatric decompressive craniectomy.
• In vivo preservation may mitigate the higher bone resorption rates observed with cryopreservation in pediatric patients.
• This approach enhances bone flap viability and may improve outcomes for pediatric cranioplasty procedures.
