Trigeminal autonomic cephalalgias. Part 3: short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing.
Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) is a syndrome characterized by severe, strictly unilateral short-lasting (between 5 and 240 seconds) pain localized to orbital, supraorbital, and temporal areas, accompanied by ipsilateral conjunctival injection and lacrimation. It represents 1 of 3 primary headaches classified as trigeminal autonomic cephalalgias (TACs). Although its prevalence is extremely small, SUNCT patients may present at dental offices seeking relief for their pain. It is important for oral health care providers to recognize SUNCT 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. The following article is part 3 of a review on TACs and focuses on SUNCT. Aspects of SUNCT, including epidemiology, genetics, pathophysiology, clinical presentation, classification and variants, diagnosis, medical management, and dental considerations are discussed.
