Schellekens, P. Lohuis] Chronic daily headache (CDH) located in the frontal region is a common problem. We have previously described the positive results that were achieved with botulinum toxin (BTX) injections in the musculus corrugator supercilii (MCS) for this disorder. Nowadays, we offer transection of this muscle to patients following a minimum of two BTX injections, provided these injections result in a significant reduction of pain. This procedure is based on the assumption that the pathophysiological mechanism in some of these patients suffering from CDH is a neural entrapment of the supratrochlear nerve in the corrugator muscle. To assess the effect of transection, we have evaluated all the consecutive patients (n=10) so far. Treatment was successful in nine of these patients. Prior to the treatment, the mean pain score in the 9 successfully treated patients was 8.1 (range 6-9), after transection this had been reduced to 0.8 (range 0-3). All of these successfully treated patients ceased their daily use of pain relief medication for their frontally localised headaches. Moreover, they stated that they would definitely undergo surgery, if they were to find themselves in the same situation again. Therefore, we conclude that transection of the MCS is an efficient and successful procedure for a carefully selected group of patients suffering from CDH in the frontal region. Most of all we intend to popularise this pathophysiological concept based on the distinct possibility that some headaches might be due to neural entrapment.
