Surgery

In generalanesthesia, and after surgical preparation of both exelids, the recipient bed of the upper eyelid defect was prepared by dividing the lid skin and tarsus from the palpebral conjunctiva. Dissection for the upper border of the defect continued toward the conjunctival fornix for 10-15 mm to separate the palpebral conjunctiva sufficiently. The eyelid was split into skin – orbicularis oculi muscle, and tarsus – palpebral conjunctiva for a distance 3 mm into the normal eyelids. A right – angle incision at the nasal end of the defect was prepared by scissors to accommodate the tip of the pedicle graft.

The pedicle graft was prepared with cca 15 mm incision starting in the lateral canthus, 2 mm perallel to the lower eyelid margin; the second parallel incision was provide a pedicle, which was 1 mm wider than the length of the upper defect, The length of the pedicle was the same as the length of the defect; but the base of the pedicle graft was wider than its tip – for adequate perfu sion of entire pedicle (fig. 3). After reposition of the pedicle to the defect, both parts of tissue was sutured; deep layer –recipient and donor tarsus by 5-0 simple continuous absorbable suture. The skin and orbicularis oculi layers were apposed and sutured with 5-0 simple interrupted non –absorbable sutures, The posterior part of the graft was covered by palpebral conjunctiva.

The lower eyelid wound was apposed with 4-0 simple interrupted non –absorbable sutures (fig. 4). The postoperative care was focused on the healing of the corneal defect and wound protection. An E collar was worn until the healing process completed and sutures were removed. With this type of plastic surgery – Roberts and Bistner procedure for the treatment of eyelid agenesia we achieved good cosmetic and functional effect. This method allows a very good possibility of reconstructive surgery, not only in eyelids agenesis, but also in cases of extensive injuries and eyelid tumors. Another p...
