SYNOPSIS

Wolff described three types of post-traumatic headaches (PTH). In type II PTH, the pain is located at the site of injury. Local soft tissue trauma and direct damage or entrapment of sensory nerves in the scar tissue are thought to be responsible for this type of headache. It is often difficult to study the neurological and autonomic changes in the scalp in these patients. We report here 8 patients with PTH in whom the site of injury was on the face thereby allowing us to evaluate the local neurological changes with greater accuracy. The results of this study corroborate Wolff's view of the pathogenesis of type II or “site of injury” PTH.
