Background: The influence of orbital fractures and their repair on the rate of deformities of the lower eyelid isan ongoing source of discussion in the literature. Most of the present studies include isolated blow-out as well ascombined orbital fractures.Material and Methods: We present a retrospective evaluation of a series of 100 patients after isolated blow-outfracture repair using reference anthropometric data on standardized photographs. Analysis included eye fissurewidth and height, lid sulcus height, upper lid height, upper and lower iris coverage, position of cornea to palpebrainferior, canthal tilt, scleral show, ectropion and entropion. It was clearly distinguished between operated and contralateraleyelid, whether a transconjunctival or a subciliary approach was performed and amount of fracture. Ourmain interests were changes of the aforementioned parameters with regards to eyelid deformities.Results: Surgery per se did not significantly influence eyelid deformities. However, the surgical approach selectedsignificantly affected eye fissure index, lower iris coverage and rate of scleral show, indicating retraction of thelower eyelid.Conclusions: The standardized measurements described here are accurate and objective to evaluate postoperativeresults. The subciliary approach included the highest risk of lower lid retraction as compared to transconjunctivalapproaches.
