title: Primary peg placement in evisceration with the spherical porous polyethylene orbital implant.
abstract: OBJECTIVE
  To determine the efficacy of primary placement of a motility coupling post (MCP) in evisceration with the porous polyethylene (PP) implant.
  
  
  METHODS
  Retrospective noncomparative, interventional case series.
  
  
  METHODS
  Twenty patients undergoing evisceration.
  
  
  METHODS
  A modified evisceration technique with porous polyethylene implants was performed, in which an MCP was placed primarily during the initial surgery. All patients were observed postoperatively for a minimum of 3 months.
  
  
  METHODS
  Socket motility, final position of the MCP in the orbit, patient satisfaction.
  
  
  RESULTS
  At the last follow-up visit, an acceptable range of motility was attained in all patients. Nineteen patients had a centrally positioned MCP, and all patients were pleased with the cosmetic outcome and the range of motility achieved. Minor complications were noted, including a malpositioned MCP (n = 1) and poor motility in upgaze (n = 8).
  
  
  CONCLUSIONS
  Primary peg placement at the time of evisceration with the PP implant is a promising technique with relatively minor complications so far, but properly constructed studies are required prospectively to compare motility with the MCP versus nonpegged implants.
