Abstract
BACKGROUND
Headache is a common, yet challenging symptom to evaluate given its wide range of clinical presentations and different etiologies. For centuries, conceptual understanding of headache causation has been attributed to anatomic abnormalities of the nose and paranasal sinuses.
METHODS
Structured literature review.
RESULTS
The number of cases, categorized as migraines or other primary headaches, misdiagnosed as a "sinus headache" is high in the literature, ranging from 50 to 80%. The potential mechanisms for rhinogenic headaches were classically described as pain secondary to prolonged mucosal contact points, hypoxia in the paranasal sinuses secondary to poor ventilation, or pressure caused by the growth of nasal polyps. Additionally, other mechanisms were described and are still being studied. Corrective surgery for mucosal contact points in the nasal cavity is deemed necessary for relieving the headache, although patient outcomes are variable.
CONCLUSION
Delay in proper diagnosis and treatment negatively impact patient quality of life. Most cases of "sinus headache" or "rhinogenic headache" seen in clinical practice are in fact misdiagnosed as either primary headaches or migraines. Because of increased misdiagnoses, Otolaryngologists should establish a direct and precise diagnosis congruent with a chief complaint being a headache. Vital information such as a good clinical history, well-performed nasal endoscopy, and occasional CT scan may decrease misdiagnosis probability.
