AbstractParoxysmal hemicrania (PH) is characterized by severe, strictly unilateral pain attacks lasting 2 to 30 minutes localized to orbital, supraorbital, and temporal areas accompanied by ipsilateral autonomic features. It represents 1 of 3 primary headaches classified as trigeminal autonomic cephalalgias. Although PH is rare, patients may present to dental offices seeking relief for their pain. It is important for oral health care providers to recognize PH and render an accurate diagnosis. This will avoid the pitfall of implementing unnecessary and inappropriate traditional dental treatments in hopes of alleviating this neurovascular pain. This is part 2 of a review on trigeminal autonomic cephalalgias and focuses on PH. Aspects of PH including epidemiology, genetics, pathophysiology, clinical presentation, classification and variants, diagnosis, medical management, and dental considerations are discussed.
