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.     

Lymphedema of the eyelids

Lymphedema of the eyelids is a relatively rare condition whose main effect is to obstruct vision, and it is unsightly. We present 3 cases in which the edema was treated by excision and skin grafting of the eyelid, with satisfactory functional and cosmetic results. It is suggested that a split-skin graft be used for the upper eyelid and a full-thickenss graft for the lower eyelid. The lower eyelid skin can be "de-fatted" and used as a graft, but in the more severe cases we suggest a postauricular skin graft be used.     

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.     

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.     

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.     

Reconstruction of the medial half of the lower eyelid using a "switch" split-lid procedure

Reconstruction of the medial half of the lower eyelid has one major disadvantage: It produces a scar at right angles to the eyelid rim. In contrast, use of a "switch" split-lid procedure avoids this inconvenience. The lateral half of the lower eyelid is split in two lamellae. The inner layer is transferred medially, and the resulting defect is closed with a buccal graft. The outer layer is drawn laterally to cover the raw surface of the mucosal pedicle and graft. The surplus of skin over the lateral canthal area is removed. This procedure, which so far has been used in three patients, promises to be a useful alternative for reconstruction of the medial half, but not more, of the lower eyelid.     

The use of conchal cartilage graft in involutional entropion

A simple and stable technique for repairing involutional entropion is described. Through a transconjunctival incision between the lower border of tarsus and the lower lid retractor, the eyelid is divided between the tarsus and the orbicularis oculi muscle into external and internal layers. The internal layer is moved upward until the eyelashes turn outward, and then through-and-through sutures are placed to fix it in this corrected state. The resultant defect between the lower end of the tarsus and the retractor is filled with a conchal cartilage graft. The raw surface of the cartilage is epithelialized from the surrounding mucosa within 1 to 2 weeks without shrinkage. This technique is more stable than any other technique that we have performed.     

Upper eyelid skin grafting: an effective treatment for lagophthalmos following blepharoplasty

Patients who have undergone upper blepharoplasty occasionally develop anterior lamellar insufficiency, which can result in lagophthalmos, corneal decompensation, and even blindness. Historically, skin grafts in the upper eyelid have been considered a last-resort procedure because of poor cosmetic outcomes. Poor cosmetic outcomes result from the traditional practice of placing the skin graft above the eyelid crease. This article describes a surgical technique for upper eyelid skin grafting in which the graft is placed in a supraciliary position. Presented are results of a retrospective study of 20 patients (31 eyelids) who underwent supraciliary upper eyelid skin grafting. The postoperative results were evaluated by examining the improvement in lagophthalmos, the improvement of keratopathy and comfort of the patient, and the cosmetic appearance of the graft. Upper eyelid skin grafting using this surgical technique is an effective and cosmetically acceptable method to improve corneal integrity and comfort in patients who have corneal exposure from insufficient anterior lamella after upper eyelid or eyebrow surgery.     

Conchal cartilage and composite grafts for correction of lower lid retraction

Lower eyelid retraction may be due to vertical deficiency of the anterior lamella, supporting cartilage, or posterior lamella. We have used autologous cartilage grafts from the conchal bowl for reconstruction of the central lamella, reestablishing and augmenting support of the lower lid. The positioning of the graft is dependent on the specific anatomic deficiency, and the etiology of the lid retraction must be carefully evaluated. In patients with posterior lamella deficiency, the contracted lower lid retractors and conjunctiva are released and the graft is placed facing the bulbar conjunctiva and is allowed to reepithelialize. In patients in whom there is an associated skin deficiency, composite auricular grafts are used. We present our experience in 33 patients with lower lid retraction. Twenty-three patients required placement of a cartilage graft only, while 10 patients had an associated skin deficiency requiring placement of composite cartilage. In nine patients the cartilage graft was seated against the bulbar conjunctiva and allowed to reepithelialize. Reepithelialization was complete within 3 1/2 weeks in all but two of these patients. This technique has provided stable lid support in all 33 patients.     

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.     

Lid margin reconstruction with an orbicularis oculi musculocutaneous advancement flap and a conchal cartilage graft

A simple method to reconstruct the midlateral lid margin defect is described using an orbicularis oculi musculocutaneous advancement flap and a free conchal cartilage graft. This method is easy to perform not only in the lower eyelid, but also in the upper one, provides a natural gray line and a stable lid margin without postoperative eversion, and substitutes for the Leone and van Gemert procedure.     

Lower eyelid reconstruction with the upper eyelid rotation flap

A new technique of lower eyelid reconstruction was developed by using an ipsilateral upper eyelid rotation flap. After resection of a tumor in the lower eyelid, it is possible to replace the defect by a full-thickness upper eyelid rotation flap. Knowledge of exact eyelid anatomy is necessary to perform this kind of operation. In addition to the well-known techniques, the rotation flap constitutes a complete anatomic reconstruction of the lower eyelid with no functional loss of the upper eyelid.     

The evaluation and management of lower eyelid retraction following cosmetic surgery

Lower eyelid retraction is a common complication after cosmetic surgery of the lower eyelids, midface, and the adjacent face. Lower eyelid retraction is defined as the inferior malposition of the lower eyelid margin without eyelid eversion. Lower eyelid retraction presents clinically with scleral show; round, sad-looking eyes; lateral canthal tendon laxity; and symptoms of ocular irritation, including photophobia, excessive tearing, and nocturnal lagophthalmos. These patients frequently require ocular lubricants, including artificial tears and ointments, which often provide only minimal alleviation of their symptoms. The author has observed that lower eyelid retraction is usually accompanied by midface descent. On the basis of surgical observations, the causes of lower eyelid retraction seem to be multifactorial and include scarring between the orbital septum and capsulopalpebral fascia (or lower eyelid retractors), lateral canthal tendon laxity, and midface descent. After describing the causes of lower eyelid retraction, the author presents a system for evaluating patients that can assist the surgeon in choosing the surgical procedure(s) required to correct the lower eyelid malposition. The surgeon must know how to tighten a lax lateral canthal tendon, be familiar with the anatomy of the lower eyelid from conjunctiva to skin side, and know how to surgically elevate the midface. The techniques for correcting lower eyelid retraction are also presented. Appropriate surgery, which is determined on the basis of the preoperative evaluation, has allowed for the correction of these previously difficult-to-treat lower eyelid malpositions with minimal complications.     

Long-term comparison of a newly designed gold implant with the conventional implant in facial nerve paralysis.

Patients with complete facial nerve palsy are at risk for eye complications resulting from exposure of the cornea and loss of the blinking reflex. Failure of protection predisposes the patient to exposure keratitis, corneal abrasion and, in rare cases, blindness. The mainstays of non-surgical therapy are cumbersome, obscure vision, and are mostly helpful in patients with acute facial paralysis in whom recovery of orbicularis oculi function is expected. Methods of lid-loading using metal implants and gold eyelid weights have been reported in the literature. Between October of 1988 and March of 1995, 32 patients with lagophthalmos due to facial nerve palsy underwent a total of 34 procedures for the insertion of a gold eyelid weight. Each patient had a gold weight inserted into a small pocket between the orbicularis oculi and the tarsal plate of the upper eyelid. The gold implant is curved to fit the curvature of the eye and contains holes for fixation to the tarsus with sutures. Ingrowth of fibrous tissue through the holes may also help fix the weight in position. Between 1988 and 1991, 10 patients received 10 commercially available rectangular gold implants with 2 holes; these implants resulted in adverse effects, such as infection and exposure in up to 30 percent of the cases. Because of the high complication rate with the rectangular gold implant, the authors began using a new, elliptical gold implant with 3 holes, which is longer, thinner, wider in the center, and narrower in the peripheral portion. This new elliptical implant was used on 22 patients (24 implants) from December of 1991 through March of 1995. The mean follow-up time for the 32 patients in the study was 41.3 months (range, 6 to 63 months), 49.8 months for patients with rectangular implants and 32.8 months for patients with elliptical implants. The elliptical gold implant resulted in dynamic closure of the eyelid and in excellent protection and cosmesis. Lagophthalmos and exposure keratitis resolved, visual acuity significantly improved without complications, and most patients could dispense with eyedrops and salves. A lower eyelid supporting procedure (conchal cartilage graft) should be performed simultaneously in patients with lagophthalmos of a moderate or severe degree to achieve complete closure of the eyelid. Use of a tall pillow decreased the incidence of eyelid opening during sleep. Double eyelid fold operations'were performed on the contralateral eyelid after 6 months, resulting in a symmetrical and beautiful eyelid.     

Histological and Ultrastructural Studies on the Conjunctiva of the Barred Owl (Strix varia)

This report is the first characterization of the histology and ultrastructure of the barred owl conjunctiva. The inferior eyelid was dominated by a large disk-shaped plate covered by a non-keratinized stratified squamous or cuboidal epithelium of variable thickness. The apical surface of the plate epithelium varied from flat to long microvilli or even short cytoplasmic extensions similar to those seen in the third eyelid. All specimens had a few goblet cells filled with mucous secretory granules in the plate region. The underlying connective tissue was a dense fibroelastic stroma. Eosinophils were surprisingly common in the epithelial layer and underlying connective tissue in the plate and more distal orbital mucosal region. The orbital mucosa contained goblet cells with heterogeneous glycosylation patterns. The leading edge and marginal plait of the third eyelid are designed to collect fluid and particulate matter as they sweep across the surface of the eye. The palpebral conjunctival surface of the third eyelid was covered by an approximately five-cell-deep stratified squamous epithelium without goblet cells. The bulbar surface of the third eyelid was a bilayer of epithelial cells whose superficial cells have elaborate cytoplasmic tapering extensions reaching out 25 μm. Narrow cytofilia radiated outwards up to an additional 15–20 μm from the cytoplasmic extensions. Lectin labeling demonstrated heterogeneous glycosylation of the apical membrane specializations but only small amounts of glycoprotein-filled secretory granules in the third eyelid.     

Microstructure of the eye tunics,eyelids and ocular glands of the Sulawesi bear cuscus (Ailurops ursinus Temminck, 1824) (Phalangeridae: Marsupialia) based on anatomical,histological and histochemical studies

This study described the anatomy, histology and the histochemical analysis of the eye tunics, the upper and lower eyelid, the third eyelid, the lacrimal gland and the superficial gland of the third eyelid in adult Sulawesi bear cuscus. The eyeball and the eyelids with the orbital glands were harvested immediately post-mortem. The eyeball in the Sulawesi bear cuscus had a sphere-like shape. The pupil was round, and the lens was a circular biconvex body. There was neither tapetum lucidum nor Harderian gland. Similarly, there were no eyelashes in the lower eyelid. The lymphoid follicles and the high endothelial venules (HEV) were found in the lymphoid region only in the third eyelid and in the connective tissue of the superficial gland of the third eyelid. The third eyelid in the bear cuscus resembled the letter “T.” The lacrimal gland and superficial gland of the third eyelid were multilobar tubuloacinar glands. The histological analysis and histochemical studies showed that the lacrimal gland in the Sulawesi bear cuscus produced a mucoserous secretion with predominantly serous cells. In contrast, the superficial gland of the third eyelid produced a serous secretion with a single acinus mucous in character.     

The differences in the eyelids microstructure and the conjunctiva‐associated lymphoid tissue between selected ornamental and wild birds as a result of adaptation to their habitat

The aim of the study was to describe the morphology of the upper, lower and third eyelid and characterize the organized lymphoid follicles and diffuse lymphocytes from ornamental and wild birds. The goal of these examinations was also to identify avian conjunctiva‐associated lymphoid tissue (CALT) and lymphoid tissue that contained specialized high endothelial venules. The upper, lower and third eyelid from 30 species of ornamental and wild birds representing 21 families were examined under light microscopy and using scanning electron microscopy. The third eyelid in all of the examined birds was composed of a free margin, which was divided into two parts. The largest tarsal plate of the third eyelid was observed in the greater rhea (Rheimorphae), the white‐tailed eagle and steppe eagle (Accipitrimorphae) and was approximately 13–15 mm wide and 9–11 mm long, respectively. In all of the examined birds, the CALT was associated with a rich network of small vessels. In addition, the presence of characteristic high endothelial venules and roundish bright endothelial cells was confirmed in the upper and lower eyelids or only in the lower eyelid (Phoenicopterimorphae, Procellariimorphae and Strigimorphae).     

Transblepharoplasty lower eyelid and midface rejuvenation: part II. Functional applications of midface elevation

Lower eyelid malposition is the cause of many ophthalmologic complaints, including ocular foreign-body sensation, irritation, excessive tearing, and sensitivity to light. The lower eyelid and midface are intimately associated structures. Midface descent frequently occurs in conjunction with lower eyelid laxity and descent. Elevating the lower eyelid and midface back to their normal anatomic positions frequently improves symptoms in these patients. The author has utilized the same techniques frequently used by aesthetic surgeons to elevate the lower eyelid and midface for patients, with improvement or resolution of their ocular complaints. The technique and results are presented.     

The superficial lateral canthal tendon: anatomic study and clinical application to lateral canthopexy

Most patients who undergo facial cosmetic surgery procedures that could cause lower eyelid retraction or ectropion should have an additional surgical procedure to support the lower eyelid and lateral canthus. The lower eyelid should be supported when performing laser planing of the eyelid; midface elevation through a lower eyelid incision approach; or conventional blepharoplasty, in patients with lower eyelid laxity. Suspending the lateral canthus by surgically altering the lateral canthal tendon is a proven technique that can provide support for the lower eyelid. However, a technique of this complexity may be unnecessary for most cosmetic surgery patients. To increase understanding of the fascial support system of the lateral canthus, four fresh cadaver dissections were performed to investigate the attachments of the lateral canthus to the lateral orbital rim. The most commonly appreciated attachment between the eyelids and the lateral orbital rim is the lateral canthal tendon (the lateral canthal raphe). However, the lateral canthus also is attached to the orbital rim at a more superficial level through the septum orbitale. This superficial fascial plane may be modified and used as a structure to stabilize or suspend the lateral canthus. This structure is defined in this article as the "superficial lateral canthal tendon."     

Malignant melanoma of the palpebral conjunctiva in a captive fallow deer.

A case of malignant melanoma in the conjunctiva of the eyelid of a captive 13-yr-old female fallow deer (Dama dama) was studied. The black tumor that protruded to the palpebral conjunctiva of the right lower eyelid consisted of an infiltrative growth of melanin-containing neoplastic cells with marked cytological atypia. The tumor involved the conjunctiva of the right lower eyelid and infiltrated to the conjunctival epithelial layer, but did not reach the palpebral skin. Numerous mitotic figures and lymphatic invasions were observed. This is a very rare case of a malignant melanoma arising from the palpebral conjunctiva in a wild ruminant.
