Scalp and Dural Reconstruction With a Tensor Fascia Lata Myofascial and Anterolateral Thigh Fasciocutaneous Chimeric Flap: A Case Report

Composite scalp and cranial defects present a challenge due to the unique elements that need to be reconstructed. The goals of reconstruction are to protect intracranial contents, prevent cerebrospinal fluid leak (CSF) and infection, and to provide durable soft tissue coverage. We present a case of an immunocompromised patient with history of craniotomy who developed osteomyelitis and a cranial abscess resulting in a composite defect with dural, bony, and soft tissue loss. To achieve vascularized watertight dural repair and durable soft tissue coverage for resolution of infection and eventual staged cranioplasty, we performed a free tensor fascia lata (TFL) myofascial and anterolateral thigh (ALT) fasciocutaneous chimeric flap. The patient healed well without CSF leak or infection at 5-month follow-up and cranioplasty is planned. Use of a chimeric TFL and ALT flap is effective in the treatment of large, composite cranial defects in the setting of active infection.
