title: Preseptal transconjunctival approach for orbital floor fracture repair: ophthalmologic results in 209 patients.
abstract: CONCLUSIONS
  The transconjunctival approach to orbital floor fractures permits excellent exposure of the inferior orbit and provides a good surgical outcome, especially with regard to ocular motility.
  
  
  OBJECTIVE
  Surgical access to orbital floor fractures can be accomplished via the transconjunctival approach. The majority of studies on this subject deal with surgical aspects and complications. The purpose of this study was to report the ophthalmologic outcome after transconjunctival orbital floor fracture repositioning in a significant number of patients.
  
  
  METHODS
  In a retrospective study, the data of 209 patients with orbital floor fractures treated via the transconjunctival approach with (n=181) and without (n=28) lateral canthotomy were analyzed.
  
  
  RESULTS
  The commonest cause of injury was forms of violence (32%). An isolated fracture of the orbital floor had occurred in 62 cases, while concomitant facial fractures were present in the remaining 147. A total of 24 patients (11%) had an exophthalmos and 13 (9%) an enophthalmos. Most patients (69%) complained of infraorbital dysesthesia. When elevating the eyeball, the majority of patients showed a marked or severe disturbance of ocular motility (53% in abduction; 51% in adduction) and diplopia (37% in abduction; 36% in adduction). Thirteen patients required repeat surgery. After a follow-up period of 2 years, infraorbital dysesthesia was observed in only three patients, one of whom presented with a considerable persistent enophthalmos of 4 mm, and only four patients had persistent reduced motility and diplopia.
