Lower eyelid reconstruction with a cheek flap supported by fascia lata.

The use of a cheek rotation flap is a well-known method for reconstruction of a large defect of the lower eyelid. In this technique, a separate lining tissue supporting the cheek flap is required for full-thickness reconstruction. Previously, a chondromucosal graft or conchal cartilage has been used to support this flap. Recently, we have used a homologous or autologous fascia lata as support for the cheek flap instead of rigid tissues like cartilages. A fascia lata strip is fixed with tolerable tension to the medial canthal tendon and lateral orbital rim. The inner surface of the fascia and the cheek flap is lined with a buccal mucosa graft to decrease irritation of the conjunctiva and cornea. We present here seven patients in whom this procedure was used for lower eyelid reconstruction following resection of a malignant skin tumor. Based on follow-ups of 7 to 22 months, the functional and aesthetic results have been good in all cases. This procedure may be applicable for total or subtotal reconstruction of the lower eyelid.     

Temporoparietal fascial flap for orbital and eyelid reconstruction.

The temporoparietal fascial flap is a recognized technique for the transfer of vascularized tissue in the craniofacial region. The flap has a predictable axial vessel, provides thin vascularized tissue, and can be harvested with minimal donor-site morbidity. The temporoparietal fascial flap is well suited for orbital or eyelid reconstruction because of its proximity to the orbit. The flap is useful for reconstruction of anatomic barriers between the orbit, intracranial cavity, and paranasal sinus spaces. We present four patients in whom the temporoparietal fascial flap was used for orbital reconstruction following extirpative surgery for orbital neoplasm and two patients in whom the flap was used for lower eyelid and malar reconstruction.     

Medial canthal reconstruction using a medially based upper eyelid myocutaneous flap

Periorbital reconstruction following skin cancer ablation represents a challenging problem. A thorough understanding of the complex periorbital anatomy is necessary to preserve lid function and protect the ocular surface. The medial canthal region represents the most difficult periorbital zone to reconstruct. This area has a complex anatomy involving both the medial canthus itself and the lacrimal apparatus. The authors present their experience with a versatile technique for reconstruction of the medial canthal periorbital region, namely, a medially based upper eyelid myocutaneous flap. In the 10 patients in whom this procedure was used, there was one partial and no complete flap losses. The authors believe that the medially based upper lid myocutaneous flap offers an excellent solution to the difficult problem of medial canthal periorbital reconstruction.     

Upper eyelid reconstruction

There are several options available for upper eyelid reconstruction that depend on the extent of involvement of the anterior and posterior lamella. Knowledge of the anatomy will ensure that in addition to the creation of an aesthetically acceptable eyelid reconstruction, a functional upper lid will be restored. The purpose of this article is to outline the anatomy of the eyelid, to analyze the components of eyelid defects, and to provide options for lid reconstruction.     

Palatal grafts for eyelid reconstruction

A full-thickness graft of hard palate mucosa was used as the lining tissue for eyelid reconstruction in 11 patients over a 7-year period. An orbicularis musculocutaneous flap supplied cover and support. In all cases the mucosal graft was easily removed, convenient to handle, and took completely. The palate donor site reepithelialized by about 3 weeks postoperative and has remained healed and asymptomatic in all cases. In follow-up averaging 3 years, all the reconstructed lids have retained a stable and comfortable lid margin, with no instance of entropion or irritation. The outstanding virtue of palate mucosa for eyelid reconstruction is that it appears to retain most of its original size and stiffness over the long term and thus in a single layer can serve to replace both tarsus and conjunctiva.     

Reconstruction of both eyelids following electrical burn

A case of severe electrical burn of the unilateral upper and lower eyelids is reported, together with the surgical technique of reconstruction. A 25-year-old man suffered an electrical burn on his left eyelids. On admission, his left upper and lower eyelids were subtotally necrotic. Total eyelid reconstruction was performed 2 1/2 months later. A chondromucosal graft taken from the nasal septum was utilized as the deep layer of the upper eyelid, which was covered by sliding down the remaining levator muscle and connective tissues to maintain the blood supply to the composite graft. The outer layer of the upper lid was reconstructed with a free split-thickness skin graft. The lower lid was reconstructed with a local flap lined with a free mucosal graft. This sandwich method using the levator muscle as a core was found useful for reconstructing both the upper and lower eyelids.     

Prefabricated (expander) capsule-lined transposition and advancement flaps in reconstruction of lower eyelid and oral defects: an experimental study

In six pigs with prefabricated transposition flaps and six pigs with prefabricated advancement flaps, both flap types (lined with an expander capsule) were used to reconstruct wedge excisions of the lower eyelid or defects in the cheek/oral mucosa. The capsules replaced the conjunctiva in eyelid defects and the oral mucosa in cheek defects. Histopathologic studies were performed at 5 to 7 days, 9 to 10 days, 2 weeks, 3 to 4 weeks, and 2 and 3 months after flap reconstructions. Healing was rapid and uneventful, leading to restoration of the conjunctiva/eyelid and oral mucosa between 9 days and 2 weeks. The healing of the eyelid conjunctiva was somewhat faster than of the oral mucosa. The expander capsule acted as a conjunctival/ mucosal substitute, providing a temporary physical shield, an infectious barrier, and a matrix for epithelial regeneration. All reconstructions were successful except one oral reconstruction with early flap necrosis. Flaps lined with an expander capsule could improve and facilitate clinical reconstructions in the eyelid and oral cavity.     

Single eyelid incision for exposure of the zygomatic bone and orbital reconstruction

Experience with a single lower eyelid incision with mobilization of the lateral canthus is described for exposure of the zygoma, lower and lateral orbit, and zygomaticofrontal suture. The incision may be either subciliary with a skin-muscle flap or transconjunctival. Both require mobilization of the canthus. Reattachment of the canthus is not required in acute zygomatic fracture treatment but is preferred for secondary orbital reconstruction or in patients in whom a simultaneous coronal incision is employed. The approaches described reduce cutaneous scarring and provide generous exposure of the lower and lateral orbit. Predictable and improved aesthetic results are routinely achieved.     

One-stage reconstruction of a large upper lid defect in a newborn

Full-thickness defects of the upper eyelids require immediate reconstruction to ensure protection of the cornea. A technique is described for a one-stage reconstruction of a large congenital defect of upper eyelid in a newborn. The reconstruction was composed of a mucosa-lined transpositional musculocutaneous flap. The advantages of this method over previous methods are discussed.     

Full-thickness grafting of acute eyelid burns should not be considered taboo.

Split-thickness skin grafts are commonly used for the treatment of acute eyelid burns; in fact, this is dogma for the upper lid. Ectropion, corneal exposure, and repeated grafting are common sequelae, almost the rule. It was hypothesized that for acute eyelid burns, the use of full-thickness skin grafts, which contract less than split-thickness skin grafts, would result in a lower incidence of ectropion with less corneal exposure and fewer recurrences. The records of all patients (n = 18) who underwent primary skin grafting of acutely burned eyelids (n = 50) between 1985 and 1995 were analyzed retrospectively. There were 10 patients who received full-thickness skin grafts (12 upper lids, 8 lower lids) and 8 patients who received split-thickness skin grafts (15 upper lids, 15 lower lids). Three of 10 patients (30 percent) who received full-thickness skin grafts and 7 of 8 patients (88 percent) who received split-thickness skin grafts developed ectropion and required reconstruction of the lids (p = 0.02). No articles were found substantiating the concept that only split-thickness grafts be used for acute eyelid burns. The treatment of acute eyelid burns with full-thickness rather than split-thickness skin grafts results in less ectropion and fewer reconstructive procedures. It should no longer be considered taboo and should be carried out whenever possible and appropriate.     

Total eyelid reconstruction with free dorsalis pedis flap after deep facial burn

A case of severe facial and corneal burns with complete loss of upper and lower eyelids is reported together with the acute management and surgical options for total eyelid defects secondary to thermal injury. An acutely burned man with 78 percent total burn surface area presented with complete exposure of the left cornea. Because of the severe thermal injury, no facial tissues were available as donor sources for reconstructing the eyelid. A free dorsalis pedis flap was used to cover the exposed cornea after bilateral conjunctival advancement flaps, with septal cartilage graft for structural support. A conjunctivodacryocystorhinostomy was performed at the time of the coverage. The patient was unable to perform an exact visual acuity test; however, his gross vision was intact.     

The use of a temporal osteoperiosteal flap for the reconstruction of malar hypoplasia in Treacher Collins syndrome

The clinical use of a temporal periosteal bone flap for the reconstruction of a malar bone in a patient with the Treacher Collins syndrome is presented. The temporal muscle functions as an axial carrier of the periosteum that induces osteogenesis in young children, whereas the bone segments may serve as a nucleus for further bone formation from the periosteum. Correction of the eyelid coloboma was obtained by the rotation and advancement of a temporopalpebral flap.     

Severe ectropion: repair with a modified Tripier flap

Classical techniques, such as wedge resection, are well suited for mild cases of lower lid ectropion, but they often fail to cure severe cases. The reason these techniques often fail is because they address only the laxity and elongation of the ectropic lid, not the root cause. In nearly every case of severe ectropion, the root cause is importance of the pretarsal orbicularis muscle; i.e., there is inadequate muscle support for the pretarsal lower eyelid. A bipedicled musculocutaneous flap, transferred from the upper lid, was used to treat nine cases of severe lower eyelid ectropion. Eight patients had a good/excellent result. Four patients had electromyographic studies in the late postoperative period, without a single instance of even mild denervation. In cases of severe ectropion, this flap is an effective replacement for the missing skin and impotent muscle. It uses the often discarded blepharoplasty tissue, which has a perfect color and texture match. A single anatomic unit is rebuilt, transferring a strong new muscle strap with ideal supporting vectors and leaving scars in natural creases. This "blepharoplasty flap" may prove useful in other types of eyelid reconstruction.     

The evolution of the Hughes tarsoconjunctival flap for the lower eyelid reconstruction

The Hughes tarsoconjunctival flap was initially described in 1937. This flap is best used for reconstructing full-thickness defects involving the central portion of the lower eyelid. The evolution of this flap over the last 60 years is outlined. Several important modifications are presented; these modifications lead to decreased donor-site morbidity and improved recipient site outcome.     

Anatomic microstructure of the upper eyelid in the Oriental double eyelid

The anatomic differences in the microstructure of the upper eyelid between the double eyelid and the nondouble eyelid are compared to determine the mechanism of double eyelid formation. Tissue from the upper eyelids of normal adult women was categorized into three groups: in one group, the double eyelid was formed primarily (at birth); in a second group, the double eyelid was formed gradually; and those in a third group had nondouble eyelids. A total of 56 eyelids were studied using electron microscopy and light microscopy. The results indicated that there is a significant difference between the three groups using scanning electron microscopy. In the upper eyelid of the double eyelid, bunched fibers of levator aponeurosis penetrate through orbicularis muscle to fuse with the skin in palpebral sulcus. This structure was not observed in the group with nondouble eyelids. However, when using light microscopy, this disparity was not observed. It was concluded that a fiber-linked structure between eyelid skin and levator aponeurosis is essential for the formation of the double eyelid.     

Lower eyelid reconstruction with a conchal cartilage graft

A conchal cartilage graft without skin or mucosa was used as a posterior lining for lower eyelid reconstruction in seven patients. The raw surface of the graft was smooth enough to cause no corneal irritation and was epithelialized from the surrounding mucosa about 3 to 4 weeks after the operation. The lower eyelid reconstructed in this method produced a stable lid margin.     

Eyelids and eye socket reconstruction using the expanded forehead flap and scapha composite grafting.

After trauma or excision of malignant tumor, it is difficult to achieve satisfactory results when reconstructing deformed eyelids and the socket for an ocular prosthesis. The authors demonstrate examples of successful reconstruction for a prosthetic eye that provided adequate and aesthetic soft-tissue support achieved by applying a three-step surgical procedure of reconstruction of the eye socket, the eyelids, and the tarsus and eyelid margin. Because it is highly vascularized and its distal end can be divided into two or three portions for easy three-dimensional reconstruction, the expanded forehead flap alone, with a galea flap, or with a free rectus abdominis muscle perforator flap was used. The expanded forehead flap also provides excellent thin upper lid contour and good color-matching with a recipient site. For the eye socket, sufficient volume of tissue was provided from the expanded forehead flap with or without a galea or a free rectus abdominis muscle perforator flap, and a deep and convex fornix was formed. This resulted in a good fit and in stability of the ocular prosthesis. The surface and the inner lining of the eyelids were reconstructed using portions of the expanded forehead flap. For the tarsus and eyelid margin, conventional reconstruction techniques use cartilage of the concha, which has limitations of length and which does not fit the shape of the tarsal margin. The authors used the scapha composite graft, and a natural shape and good elasticity resulted.     

Reconstruction of the entire upper eyelid area with a subcutaneous pedicle flap based on the orbicularis oculi muscle

Lagophthalmos caused by trauma or inflammation may damage the cornea and, if not adequately treated, may result in loss of eyesight. Hence surgical intervention is required at the earliest possible stage. We have developed a subcutaneous pedicle flap elevated from the temporozygomatic area and rotated 180 degrees around a small pedicle base that contains the orbicularis oculi muscle. With this flap, the entire upper eyelid can be reconstructed as an aesthetic unit in one stage so that the result is satisfactory not only functionally, but also cosmetically. The operative procedure is presented along with case reports.     

Upper and lower eyelid reconstruction

Reconstruction of the eyelids can range from simple repair to the integration of multiple complex procedures. Knowledge of eyelid anatomy, adequate preoperative planning, and meticulous surgical technique will optimize the anatomical and functional result. The purpose of this article is to review the relevant anatomy for eyelid reconstruction, to simplify defect analysis and preoperative planning, and to provide options for reconstruction of this complex area.
