Resumen:
The presence of foreign material in deep brain stimulation is a risk factor for infection, and hardware-related pressure under the scalp may cause skin erosion. The aim of this article is to present our experience in the coverage of scalp in relation to underlying hardware. We analyzed 21 patients with Parkinson disease who had undergone deep brain stimulation surgery and developed scalp erosion with hardware exposition during follow-up. Nine patients were programmed for a scalp rotation flap, whereas free tisue transfer was performed in the rest of the patients. Minimum follow-up was 2 years. A hardware-related ulcer appeared in 5 of 9 rotation flap patients. No ulceration or major complications were observed in free flap patients. Free flaps are probably the best option for stable coverage in hardware-related scalp erosion with a high rate of success.
