Abstract
We report here the case of four patients presenting with delayed-onset temporal pain after pterional craniotomy. They reported similar symptoms: attacks of pain over the temporal region, ipsilateral to the operative site, irradiating around the eye and lasting from 10 min to 1 h. All patients had hypertrophy of at least one part of the temporalis muscle. All responded dramatically to botulinum toxin A injection (25 to 50 Botox® units) into the temporalis muscle. We suggest that the headaches were caused by aberrant nerve regeneration following surgical injury to the frontal branch of the facial nerve.

Comments
Postcraniotomy pain associated with temporal muscle hypertrophy was successfully treated with local botulinum toxin injections in four patients. The authors are to be congratulated for their novel observation and therapeutic ingenuity. As they rightly point out, postcraniotomy pain is under-reported in the literature and has a multifaceted pathophysiology. In this small patient cohort hypertrophy of the painful temporal muscle suggested the use of botulinum toxin. The up to 2 week latency for pain relief suggests a secondary inflammatory component to the pain.
