Minimal evisceration combined with orbital implantation

Background: To evaluate the minimal evisceration technique, which aims to reduce surgical damage and complications and achieve better cosmetic outcomes.Methods: Eighty patients were enrolled from January 2013 to January 2019. All of the patients underwent a minimal evisceration and hydroxyapatite (HA) implant procedure, including making a lateral incision on the sclera only, transecting the optic nerve, and placing an HA implant behind the posterior sclera in the muscular cone. The implant was covered by two layers of the sclera. The main outcome measures were surgery time, blood loss, days of hospitalization, time interval for placement of prosthesis after surgery, complications, such as implant extrusion or exposure, enophthalmos, conjunctival sac stenosis, and cosmetic outcome.Results: All of the patients received minimal evisceration combined with an orbital implant. The average surgery time was 30 min, blood loss was 3 ml, days of hospitalization were 3, and the time interval for placement of the prosthesis after surgery was 4 week. No complications were recorded. The cosmetic appearance and implant mobility were satisfactory.Conclusions: This technique has advantages such as less damage, fast recovery, good effects and fewer complications. It appears to be a perfect modification for anophthalmic socket reconstruction.

Single-Stage Orbital Socket Reconstruction Using the Oversized Dermis Fat Graft and the 22 mm Silicone Orbital Implant after an Extended Enucleation

We would like to present a surgical technique of orbital socket reconstruction using oversized dermis fat graft and 22 mm silicone orbital implant in a single-stage after extended enucleation in two patients with massive local recurrence of anteriorly located choroidal melanoma previously treated with endoresection. Orbital tissues en bloc were removed leaving conjunctival lining only at the fornices. Simultaneously, the 22 mm silicone sphere was implanted deeply into the orbit and covered with the oversized dermis fat graft of 30 mm in height and 35 mm in length with 20 mm of the fat thickness. The graft was sutured to the residual forniceal conjunctiva with interrupted 6/0 absorbable sutures overlapping conjunctiva with the graft edge for 2 mm to facilitate the epithelization. Epithelization was completed in two months, leaving well-formed fornices with good fitting of the prosthesis. The key point of orbital socket reconstruction after extended enucleation is to restore conjunctival lining prior to volume. Thus, whenever facing a massive volume and conjunctival lining loss, simultaneous insertion of the 22 mm silicone sphere deep into the orbit combined with oversized dermis fat graft is, in our opinion, the method of choice. It proved to be safe and effective with favourable long-term results.
