Use of a chronic soft tissue expansion device to facilitate blepharoplasty in a horse with lower-lid cicatricial ectropion with a 14-year follow-up.

Abstract: A 3-year-old Thoroughbred filly presented to a referral equine hospital for surgical correction of a severe cicatricial lateral lower eyelid ectropion OD, with secondary exposure keratitis. The severity of the ectropion deemed that conventional ectropion repairs would be unsuccessful. Therefore, a soft tissue expansion device was used to create sufficient local tissue for a rotational graft with tension-relieving horizontal incisions to be performed to facilitate closure and acceptable eyelid apposition. The keratitis had resolved by two months postoperatively. There were no long-term complications and only mild recurrence of the keratitis observed 14-years postoperatively.

This research paper refers to a case study about the successful use of a novel surgical technique involving a soft tissue expansion device to repair a severe eyelid deformity (ectropion) in a young horse, with sustained results over a 14-year follow up period.

Case Description

  • The study focuses on a 3-year-old Thoroughbred filly that was brought to an equine hospital for the surgical correction of a severe cicatricial (scarred) lateral lower eyelid ectropion on the right eye (OD). This condition causes the eyelid to turn outwards, which exposed the cornea, leading to secondary keratitis (cornea inflammation).

The Nature of the Problem

  • The severity of the filly’s ectropion was such that conventional surgeries for the repair of ectropion were expected to fail. This predicted failure was because these approaches would not be able to provide the required additional tissue needed to correct the eyelid positioning effectively while avoiding undue tension on the surgical sites.

Surgery Method

  • To overcome this challenge, surgeons used a soft tissue expansion device – a balloon-like implement that can be inserted beneath the skin and gradually inflated to ‘expand’ the surrounding tissue over time. This process aimed to create enough local tissue to be used for a rotational graft to correct the mispositioned eyelid. This strategy also deployed tension-relieving horizontal incisions to reduce pressure on the surgical sites.

Postoperative Results

  • The keratitis condition was resolved two months after the procedure, indicating that the eyelid was sufficiently positioned to cover and safeguard the cornea. This protection is vital because it demonstrates that the surgical repair of the ectropion was successful.

Long-term Follow-up

  • Following a 14-year follow-up period, the study reported that there were no long-term complications associated with the procedure or the innovative surgical device. A mild recurrence of keratitis was noted, pointing to a possibility of slight lessening of the effective eyelid coverage over the cornea.

Conclusion

  • The article concludes by implying the potential of the soft tissue expansion device use as a novel treatment option for severe ectropion in horses, emphasizing that the procedure yielded sustained positive results over a long-term period.
