Total Upper Eyelid Reconstruction with Modified Cutler-Beard Procedure Using Autogenous Auricular Cartilage

Surgical Strategies for Eyelid Defect Reconstruction: A Review on Principles and Techniques

Reconstruction of eyelid defects, especially the posterior lamella, remains challenging because of its anatomical complexity, functional considerations, and aesthetic concerns. The goals of eyelid reconstruction include restoring eyelid structure and function and achieving an aesthetically acceptable appearance. An in-depth understanding of the complex eyelid anatomy and several reconstructive principles are mandatory to achieve these goals. Currently, there are multiple surgical treatment options for eyelid reconstruction, including different flaps, grafts, and combinations of them. This comprehensive review outlines the principles of reconstruction and discusses the indications, advantages, and disadvantages of currently available surgical techniques. We also propose our clinical thinking for solving specific clinical questions in eyelid reconstruction and offer perspectives on new potential methodologies in the future.

Auricular cartilage versus donor sclera as a wrapping of hydroxyapatite orbital implants

AIM

To retrospectively compare postoperative outcomes after primary enucleation and placement of a hydroxyapatite (HA) implant without wrapping, wrapped with auricular cartilage or donor sclera.

METHODS

Medical records of patients presented as intraocular tumor or severe ocular injury were identified from the electronic medical record system. Cases underwent enucleation and HA orbital implantation were enrolled in this study and were divided into 3 groups according to the wrapping material of HA implant. Cases with autogenous cartilage caps were enrolled in group A (n=11), with donor sclera caps in group B (n=12), and without any wrapping material in group C (n=9). Follow-ups were set at 1, 2wk, 1, 3, 6, and 12mo after surgery.

RESULTS

Altogether 32 cases finished the follow-up and were enrolled in this study. Three cases (27.27%) in group A, 4 cases (33.33%) in group B, and 4 cases (44.44%) in group C developed one complication each after surgery. In group A, no HA exposure occurred, but conjunctival inclusion cyst occurred in one and severe conjunctive chemosis in two cases. In group B, one HA exposure occurred, conjunctive inclusion cysts occurred in one, severe conjunctive chemosis occurred in one, and conjunctival granuloma occurred in one case. In group C, one HA exposure occurred, severe conjunctive chemosis occurred in two cases, and conjunctival granuloma occurred in one case. The case of exposure of none-wrapped implant was noted in the first 6mo after placement of the orbital implant. The case of exposure of donor sclera-wrapped implant was noted at the 12mo after placement of the orbital implant. Both exposure cases were treated successfully with conservative treatment.

CONCLUSION

With low incidence of implant exposure and mild complications, auricular cartilage can be a good choice of alternative wrapping material of orbit implant with satisfied outcome.

Advancements in the repair of large upper eyelid defects: A 10-year review

PURPOSE

The reconstruction of large (>50%) upper eyelid margin defects can be technically challenging, with multiple approaches described in the literature. We sought to review the recent literature for new techniques or modifications to existing techniques.

METHODS

We conducted a Pubmed search for technique papers on the reconstruction of large upper eyelid defects published within the past ten years with a minimum of four patients.

RESULTS

We identified ten articles, and divided them into techniques that use a bridging flap from the lower eyelid and those that do not. The number of upper eyelids repaired in each article ranged from 4 to 17. Most techniques could be considered either a modification of the Cutler-Beard technique or a novel anterior lamella flap laid over a graft for the posterior lamella. Postoperative complications included upper or lower eyelid cicatricial retraction, trichiasis, entropion, and lagophthalmos.

CONCLUSIONS

Surgeons continue to innovate for this challenging reconstructive surgery. Overall, the trend was to use a graft, most commonly tarsoconjunctiva from the contralateral upper lid, to replace the posterior lamella, and a skin flap, from the lower eyelid or from the adjacent periorbital area, to replace the anterior lamella. Bridging techniques utilized the skin; the skin, orbicularis, and conjunctiva; or a tarsoconjunctival flap from the lower eyelid. Non-bridging techniques generally used a tarsoconjunctival or substitute graft for the posterior lamella, and a skin flap for the anterior lamella.

Eye Comfort and Physiological Reconstruction of an Entire Upper Eyelid Defect

OBJECTIVE

Reconstruction of an extensive full-thickness upper eyelid defect is challenging. The purpose of this report is to introduce this procedure with emphasis on reconstruction of the eyelid margin to obtain eye comfort.

METHODS

We designed a technique using a radial forearm flap for the outer layer to reconstruct the entire eyelid after resection of Merkel cell carcinoma. In additional, the inner layer and the eyelid margin were reconstructed with a buccal mucosal graft and a reverse Hughes flap.

RESULTS

There has been no recurrence of the tumor, opening and closing functions of the eyelid are maintained, and the patient has not complained of eye discomfort.

CONCLUSION

Maintenance of mobility, flexibility, and a good ocular surface in contact with the sensitive cornea are the main foci of upper eyelid reconstruction, with an optimal fissure height and an appropriate contour of the eyelid. In addition, to obtain eye comfort, it is important to protect the cornea without significantly restricting eyelid mobility.

Posterior lamellar reconstruction: a comprehensive review of the literature

The aim of the review is to describe the different techniques and materials available to reconstruct the tarsoconjunctival layer of the eyelid; to analyze their indications, advantages, and disadvantages. We searched the Cochrane, PubMed, and Ovid MEDLINE databases for English articles published between January 1990 and January 2017 using variations of the following key words: "posterior lamella," "eyelid reconstruction," "tarsoconjunctival," "flap," and "graft." Two reviewers checked the abstracts of the articles found to eliminate redundant or not relevant articles. The references of the identified articles were screened manually to include relevant works not found through the initial search. The search identified 174 articles. Only a few articles with a therapeutic level of evidence were found. Techniques for the posterior lamellar reconstruction can be categorized as local, regional, and distant flaps; tarsoconjunctival, heterotopic, homologous, and heterologous grafts. Several techniques and variations on the techniques exist to reconstruct the posterior lamella, and, for similar indications, there's no evidence of the primacy of one over the other. Defect size and location as well as patient features must guide the oculoplastic surgeon's choice. The use of biomaterials can avoid possible complications of the donor site.
