Intracapsular hemorrhage rates in non-fixated nylon sheet orbital implants for orbital fracture management

Abstract

Purpose: To examine the incidence of intracapsular hemorrhage in orbital fracture repair with non-fixated nylon sheet implants.

Methods: A retrospective chart review of 227 patients presenting from January 2013 to December 2016 for orbital fracture repair with nylon sheet implants.

Results: Of the 331 orbital fractures repaired over 4 years, a total of 227 met inclusion criteria. The average implant thickness was 0.38 mm and no implants were fixated. Four total implants (1.8%) were removed due to complications; one each secondary to exploration for ongoing postoperative diplopia, immediate post-operative orbital hemorrhage, a cystic mass anterior to the implant, and pain. There were no cases of intracapsular hemorrhage nor infection for any of the 227 patients over 4 years.

Conclusions: To the authors knowledge, this represents the largest case series to date to assess the rate of intracapsular hemorrhage in non-fixated nylon sheet orbital implants. In the 227 cases reviewed over a 4-year period, there were no cases of intracapsular hemorrhage. This suggests a much lower complication rate than previously reported. PRéCIS: A case series of 227 patients who underwent orbital fracture repair with non-fixated nylon sheet implants.
