광범위한 심경부 감염으로 발현된 함치성 낭종

Dentigerous cyst is one of the most prevalent types of odontogenic cysts and is associated with the crown of an unerupted or developing tooth. Although mostly asymptomatic, some of untreated denigerous cysts may displace adjacent teeth and cause complications such as jaw fracture, maxillary sinusitis or oroantral fistula. We report a 69-year-old female with dentigerous cyst, who had extensive deep neck infection which resulted in a life-threatening airway obstruction. (J Clinical Otolaryngol 2015;26:283-287)
