Sinus headache is a common presenting complaint in the otolaryngology office. While the majority of patients with this presentation are found to have migraine, many do not, and others fail therapy. This presentation focuses on case studies and the differentiation of migraine and rhinogenic headache-headaches that are caused or exacerbated by nasal or paranasal sinus pathology. The literature regarding this topic will be reviewed, along with a review of surgical series seeking to correct these abnormalities and the outcomes obtained with intervention. Recommendations will be provided regarding correct diagnosis and management in an entertaining and interactive presentation. Learning Objectives: 1.Review the literature regarding the diagnosis of sinus headache, migraine, and rhinogenic headache. 2. Review the literature regarding surgery for sinus headache and the proper identification of rhinogenic headache patients. 3. Discuss the management and workup of the typical sinus headache patient.
