Different Locations of XXXX in the Orbital Region.

@entity5 @entity1 @entity4890 @entity48
UNASSIGNED: Background: Dermoid cysts are frequent unilateral @entity5 that can be found at different locations throughout the body. In the orbital region, @entity48 occur predominantly in the supero-temporal quadrant. However, different orbital locations are possible, making this entity an important differential diagnosis for @entity5 . @entity1 and Methods: We retrospectively reviewed the charts of 23 consecutive @entity1 operated in our institution between 2005 and 2014 for @entity5 that were diagnosed as congenital dermoid or @entity4890 . Results: There were 21 dermoid and 2 @entity4890 . The median age at surgery time was 7 years (range 1-41). There were 15 females and 8 males. Eleven cysts were located supero-temporally (47.8%), seven supero-medially (30.4%), two temporally (8.7%), one at the frontal bone (4.4%) and two in the fossa of the lacrimal gland (8.7%). The mean cyst diameter was 13.1   mm      5.0 (SD). None had signs of @entity5 . No recurrence was observed after complete excision. Conclusion: Dermoid cysts of orbital region are mostly located in the supero-temporal quadrant. However, other orbital locations are possible and @entity48 must thus be considered in the differential diagnosis of any mass in the orbital region.
