Headaches are a global health problem and are encountered by a variety of specialties, including otolaryngologists. These patients can present as a challenge, but an understanding of primary and secondary headache disorders and the accompanying broad differential diagnosis is critical. For secondary headache disorders, a differential diagnosis categorized by anatomic location can help organize the evaluation of these patients, which can then be narrowed by the history and examination findings. Additional ancillary tests such as laboratories and imaging can further aid in diagnosis but are not always necessary.
