title: Orbicularis oculi muscle transposition for repairing involutional lower eyelid entropion.
abstract: OBJECTIVE
  To describe a simple technique for involutional entropion correction and to present the findings of a retrospective interventional case series study.
  
  
  METHODS
  We studied a consecutive series of 414 patients (609 eyelids). Patients presenting with involutional entropion in the absence of lateral canthal tendon laxity underwent orbicularis oculi muscle (OOM) transposition from pretarsal position to corresponding preseptum without horizontal shortening or resection of the orbicularis muscle.
  
  
  RESULTS
  Immediate resolution of entropion and associated ocular symptoms was achieved in 607 eyelids (99.67 %). An early postoperative complication was localized lid swelling that gradually subsided within one week. Over-correction occurred in six cases and resolved with pressure dressing, mostly one or two days post-operation. At final follow-up, a significant improvement in eyelid position was achieved in 579 eyelids (95.07 % ). There was mild recurrence of entropion in 30 eyelids (4.93 %). The mean follow-up was 6.84 months (range, 6-12 months).
  
  
  CONCLUSIONS
  Orbicularis oculi muscle transposition is a reasonably successful procedure with a high success rate, and is particularly suitable for patients for whom there exits overriding of the preseptal OOM over the pretarsal OOM.
