Abstract

Background 

Optimal repair of orbital fractures requires adequate exposure of the fracture area. The transconjunctival approach with lateral canthotomy has gained increasing popularity. This technique offers arguably improved visualization with lower risk of lid retraction. However, if the lateral canthotomy area is improperly repaired, it may cause lower lid malposition and deformity.1The authors report the use of a modified transconjunctival incision method with a lateral peri-canthal incision to overcome this problem in the cantholysis.

Method 

Between January 2011 and December 2012, the authors used this technique in 26 patients with orbital fractures. When the transconjunctival approach was performed, an inferolateral incision of the lower eyelid near the lateral canthus including the tarsal plate was added instead of the common lateral canthotomy incision for the cantholysis (see Figure 1).

Result

 Average follow-up was 6 months. There were no functional complications (no webbing, no ectropion, no entropion, etc) related to the operation. In 24 of 26 cases (92%) they were rated as having an excellent cosmetic outcome; however, there were two cases (8%) with complications. One patient had a subcutaneous preseptal hematoma, which required reoperation to obtain hemostasis. In another patient, there was a notch deformity on the lower eyelid margin, but the patient was satisfied and did not choose to have it revised.

Conclusions

 The authors believe that for orbital fracture repair the modified transconjunctival incision with lateral peri-canthal incision can be easily performed and reliably repaired as opposed to the more traditional lateral canthotomy technique. We believe that there is more anatomical reliability in repairing the tarsal plate rather than the attachment of the lateral canthus. Furthermore, in our experience this modified technique provided more than adequate exposure for fracture repair, with excellent cosmetic and functional result on long-term follow-up.
