title: Respiratory epithelial cysts of the orbit.
abstract: To describe post-traumatic and congenital respiratory epithelial cysts in the orbit, which are rare lesions with only 5 and 13 published cases, respectively. We reviewed all cases of respiratory epithelial cysts diagnosed at three institutions (two tertiary referral hospitals, one private clinic) between 1995 and 2015. We describe 10 cases of post-traumatic respiratory epithelial cyst (age range 23 - 82), presenting a mean of 17.4 years after their original trauma; and 3 congenital cases (age range 17-34). All but one case underwent surgical excision of the cyst and its lining, along with any surgical implant within the cyst. Two were recurrent after incomplete excision. Three presented with acute infection within the cyst. Respiratory epithelial orbital cysts are probably commoner than the paucity of published reports would suggest. Post-traumatic cysts often present many years after trauma, and may become secondarily infected. Complete surgical removal is recommended to prevent future recurrence.
