Abstract
Background: Pediatric patients with medically-intractable epilepsy may require modulation of seizure foci to reduce frequency and severity of seizures. These neuromodulatory procedures, which include responsive neurostimulator (RNS) and deep brain stimulator (DBS), involve the implantation of high-profile and long-term cranial hardware, placing patients at risk of wound healing complications, hardware exposure and infection. A multidisciplinary neurosurgical and plastic surgical approach utilizing pericranial flap coverage of hardware may decrease wound healing complications in these cases. This study compares the wound-healing outcomes in patients undergoing RNS/DBS insertion with and without pericranial flap coverage. Methods: A retrospective chart review was conducted of all patients who underwent RNS and DBS insertion with or without pericranial flap coverage at a level 1 pediatric medical center between 2014 and 2022. Wound healing outcomes at 60 days were evaluated. Data were compared using Fisher’s exact test. Results: Twenty-seven patients underwent 29 neuromodulatory epilepsy procedures (14 DBS, 15 RNS). Twenty of the procedures included a pericranial flap to cover hardware. Median length of stay was 2.0 days for both cohorts. Two subjects without pericranial flap reconstruction had a wound healing complication (22.2%), compared to none of the procedures that included a pericranial flap ( P = .09). Conclusion: In pediatric patients undergoing insertion of responsive neurostimulators and deep brain stimulators for medically-intractable epilepsy, a multidisciplinary neurosurgery and plastic surgery approach utilizing pericranial flap reconstruction may reduce the risk of postoperative wound complications.
