Results of a retrospective chart review of 80 patients, in conjunction with recently completed questionnaires, document the effects of sinus and nasal surgeries on chronic headache symptoms believed to originate within the ethmoid sinuses or nose. Seventy (88%) of the patients in this study experienced a dramatic improvement of their headache symptoms after undergoing surgical treatment. The authors conclude that this type of cephalgia is more common than expected, that its cause goes largely undiagnosed by the majority of physicians, and that an effective method of treatment is available to improve the quality of life of these patients.
