The role of free flaps in the treatment of persistent scalp osteomyelitis.

Objective: To evaluate the efficacy of the combination of an extensive surgical debridement and simultaneous free flap repair in case of troublesome cranial osteomyelitis.

Methods: Five patients with persistent, frontal bone osteomyelitis were treated with surgical debridement of the infected bone and reconstruction with a free flap. In all patients, osteomyelitis occurred after neurosurgical procedures and lasted from 1 to 7 years. A latissimus dorsi muscle flap with a split skin graft has been performed.

Results: No flap failure occurred and donor site morbidity was negligible. No signs of osteomyelitis or soft tissue infection were observed during the mean follow-up period of 3.2 years. Furthermore, the contour of the cranium could be preserved without a need for bone grafts or implants.

Conclusion: In our experience, the combination of an extensive surgical debridement and a free flap transfer is demonstrated to be an effective treatment for "chronic" osteomyelitis of the cranium.
