The eyes serve as a cosmetic focal point, and defects around the eyes resulting from congenital abnormalities, burns, trauma, or resection of cutaneous malignancies can draw significant attention and concern. The Hughes and Cutler-Beard eyelid-sharing reconstructive flap techniques can be employed to correct defects of the upper and lower eyelids, thereby improving cosmesis, function, and quality of life for affected patients. The Hughes and Cutler-Beard procedures are suitable for patients with upper or lower eyelid defects that encompass more than 50% of the total eyelid area. Despite several technical modifications since their original descriptions, both techniques remain widely utilized in modern reconstructive practice. This activity reviews some basic concepts in reconstructive surgery, the complex anatomy of the adnexa oculi, and the indications, risks, benefits, techniques, and complications of the Hughes tarsoconjunctival flap and the Cutler-Beard full-thickness cutaneoconjunctival flap. The activity also highlights the role of the interprofessional healthcare team in caring for patients undergoing these reconstructive procedures to improve surgical and cosmetic outcomes and overall quality of life. Objectives: Select patients who may benefit from a Hughes tarsoconjunctival flap or Cutler-Beard full-thickness cutaneoconjunctival flap based on their clinical findings. Assess the risks, benefits, and potential complications associated with eyelid-sharing reconstructive flap techniques. Apply evidence-based best practices when performing Hughes tarsoconjunctival or Cutler-Beard full-thickness cutaneoconjunctival flap procedures. Implement interprofessional healthcare team strategies to improve outcomes for patients undergoing eyelid-sharing reconstructive flap procedures. Access free multiple choice questions on this topic.

The reconstruction of large eyelid defects or scars presents a significant clinical challenge; there is a need for a static eyelid height that permits dynamic function and tear film production while simultaneously preventing corneal exposure due to eyelid scarring and retraction. Accomplishing these goals in an aesthetically sensitive area relies on eyelid-sharing flap techniques. The fundamental principle of these procedures is the concept of "like-with-like" replacement, where well-vascularized local tissue with optimal color and texture match is utilized for reconstruction.[1][2] The primary objectives of eyelid-sharing flap procedures are to recreate a functional eyelid that protects the corneal surface, provide an aesthetically pleasing reconstruction, and limit the morbidity of the donor eyelid. Considering the reconstructive ladder is imperative in any attempt to repair a defect. The components of the reconstructive ladder, from simplest to most complex, include healing by secondary intention, immediate or delayed primary closure, placement of split- or full-thickness skin grafts, use of tissue expanders, or use of adjacent tissue transfer, regional flap(s), or free flap(s). Minor eyelid defects may be well served using a free autograft or adjacent tissue transfer with a local or rotational flap. However, reconstruction of defects encompassing more than 50% of the eyelid benefits from a staged procedure, allowing the transposition of vascularized tissue with the later division of the vascular pedicle performed after the 1 to 4 weeks required for neovascularization. The staged eyelid-sharing flap techniques most commonly described in lower and upper eyelid reconstruction are the Hughes and Cutler-Beard procedures.[3] Wendell Hughes first described his eponymous tarsoconjunctival flap in 1937 to reconstruct lower lid defects encompassing more than 33% of the total lid area. This technique recreates a well-vascularized posterior lamella; the anterior lamellae can be reconstructed with a skin graft.[4]

This technique recreates a well-vascularized posterior lamella; the anterior lamellae can be reconstructed with a skin graft.[4] Norman Cutler and Crowell Beard described their eponymous full-thickness cutaneoconjunctival flap in 1955 for reconstructing upper eyelid defects that measure more than 50% of the lid margin. Such defects are commonly encountered in the setting of congenital abnormalities, the resection of malignancies, and eyelid trauma, including burns.[1] The original description of the Cutler-Beard flap technique reconstructs the anterior and posterior lamellae but not necessarily the tarsus.[5] The Hughes and Cutler-Beard techniques have undergone modifications in the intervening years since their original descriptions; yet, both remain workhorses for reconstructing significant eyelid defects.[6]

The skin and layered tissues of the eyelids are very thin, and close attention must be paid intraoperatively to avoid undue tension when suturing these delicate tissues. Excess tension or frank tearing of tissues compromises the final size of the available flap and increases the risk of wound dehiscence and flap necrosis.[2][12][19][12][5] Patients can develop postoperative lacrimation disorders due to the proximity of the inferior canaliculus and loss of meibomian glands.[2][3][12] Retraction and entropion of the upper eyelid after pedicle division were common complications of Hughes' original technique.[17][10][15] Newer techniques recommend releasing only the levator aponeurosis and leaving the muscle of Mueller attached to the superior portion of the tarsus.[17] The loss of eyelashes in the recipient eyelid may result in corneal irritation from surrounding skin hair.[15] Corneal irritation and ulceration may occur during flap maturation, as the flap crosses the cornea before its division.[12][11][15] Patients often reported blurred vision.[15] The development of a cicatricial scar may predispose to ectropion after a Hughes reconstruction.[2][19][5] Additionally, lower eyelid retraction is possible over time.[19][5] If extensive periosteal dissection is required during the Hughes procedure, significant edema and bruising may occur, and sensory disturbances may be perceived in the distribution of the zygomaticofacial nerve. Ectropion of the donor site, entropion or retraction of the recipient site, and the need for supplemental tissue harvest for further reconstruction are complications and drawbacks of the Cutler-Beard technique.[5][1] These complications arise because the Cutler-Beard reconstructive flap does not include the tarsus, and effective reconstruction requires the use of analogous tissues, such as auricular cartilage.[3] If the donor eyelid skin is inadequate to cover both the defect and the donor site, the donor site may be left to heal by secondary intention, which increases the risk of postoperative eyelid retraction or contraction.[15]

Patients of all ages may be affected by large eyelid defects due to congenital abnormalities, trauma, burns, or the resection of cutaneous malignancies near the eye. Patients with eyelid defects are commonly negatively affected aesthetically and functionally. Primary care and ocular health practitioners must be aware that surgical techniques can correct many eyelid defects, even those involving more than 50% of the total eyelid surface area. However, due to the risk of complications, patients who are candidates for eyelid reconstructive procedures must be treated by experienced surgeons with specific knowledge and expertise in this complex anatomical area. Although the Hughes and Cutler-Beard eyelid-sharing reconstructive flap techniques are frequently employed to correct large eyelid defects, newly published techniques for single-stage reconstruction procedures have been introduced to decrease temporary morbidity. Therefore, team members must be aware of all possible surgical options and select the procedure that best suits the situation while promoting patient safety and accommodating patient preferences.[11][16][20] Providing optimal outcomes to patients undergoing eyelid reconstructive procedures requires an interprofessional team, with all team members actively engaged in patient counseling and identifying, evaluating, and managing postoperative complications. Additionally, patients require the active engagement of an ophthalmologist to ensure optimal visual outcomes following these reconstructive procedures.
