THE ANTERIOR ethmoidal nerve syndrome is a name suggested for a series of symptoms resulting from irritation of the terminal branches of the anterior ethmoidal nerve. The referred pains arising from this nerve are chiefly of the sinus type but may also take the form of headache, sometimes of a migrainous character. Ephedrine applied to the anterior ethmoid fissure and/or the middle turbinate body has met with considerable success in the cure of the pain and headache of this origin. In April 1947, both anterior ethmoidal nerves were severed in a particularly stubborn case. The patient had not been able to carry on with her work, but since operation she has been rehabilitated. An effort will be made to apply recent physiologic discoveries in reporting the clinical course in this case.
To Littell1 goes the credit for having cut the anterior ethmoidal nerve in 2 cases of this syndrome,
