Skin expansion to eliminate large scalp defects

Area of Science:

• Plastic Surgery
• Pediatric Surgery
• Biomaterials Science

Background:

• Large scalp defects in children present significant reconstructive challenges.
• Traditional methods may involve multiple surgeries and prolonged healing times.
• The need for innovative, minimally invasive techniques is crucial for pediatric reconstructive surgery.

Observation:

• Silicone elastomer expanders were surgically placed under the scalp in three pediatric patients with large defects.
• Expanders were gradually inflated with saline over 6-8 weeks, stimulating tissue expansion.
• Hair growth was observed to continue during the expansion process.

Findings:

• The temporary expander technique successfully achieved scalp flap expansion in all three pediatric patients.
• Complete coverage of the large scalp defects was accomplished in each case.
• Two patients required a second expansion phase, with a deflated expander remaining temporarily.

Implications:

• This expander technique offers a viable solution for reconstructing large pediatric scalp defects.
• The method demonstrates potential for application in various reconstructive surgery scenarios.
• Preservation of hair growth during expansion is a significant advantage for pediatric patients.
