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.     

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.     

Weight measurement of upper eyelid gold implants for lagophthalmos in facial paralysis.

The use of the gold weight is an established procedure in the treatment of lagophthalmos and usually produces successful results. The critical technical issues are the firm suture fixation to the tarsal plate and the high location of the weight on this plate. However, the estimated weight of the implant from the trials on the skin of the upper lid fails to obtain the expected eye closure outcomes after surgical implantation on the tarsal plate. One of the main reasons could be the different curvature on the skin and on the tarsal plate of the upper eyelid. In this study, the angles between the vertical line and the surface of the outer (skin) and inner (tarsal plate) part of the upper eyelid have been analyzed when the eye is opened and closed. The results show that an addition of 0.2 g to the gold weight estimated in the trial is required to achieve a similar closure of the eye by means of the gold implant on the tarsal plate.     

The resection of orbicularis oculi muscle from the upper eyelid in experimental surgery on the monkey

The purpose of this study was to determine the maximum amount of orbicularis oculi muscle that may safely be resected from the upper eyelid without causing functional abnormalities. Measured amounts of that muscle were surgically excised from both upper eyelids in six cynomolgus monkeys. All the eyelids were photographed and videotaped at progressively increased intervals to permit the evaluation of wound healing, scarring, and function. Our preliminary results revealed that the excision of preseptal and partial supraorbital orbicularis oculi muscle, preseptal and complete supraorbital muscle, or pretarsal muscle only did not result in lagophthalmos. Complete resection of pretarsal, preseptal, and supraorbital orbicularis oculi did result in lagophthalmos but caused no corneal injury. The orbicularis oculi muscle in the cynomolgus monkey is similar to that in humans, but it is not yet clear whether our findings in the monkey are applicable in humans. A determination of the maximum amount of orbicularis oculi muscle that can safely be excised in humans would enable plastic surgeons to better understand and develop techniques for eyelid reconstruction and blepharoplasty.     

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.     

Aesthetic eyelid ptosis correction: a review of technique and cases

Upper eyelid ptosis can present both functional and aesthetic problems. Because proper correction of ptosis can be difficult to achieve, numerous surgical procedures have been developed. Plication of levator aponeurosis can be combined with aesthetic blepharoplasty and facial rejuvenation procedures to successfully address ptosis. The authors assessed the effectiveness of levator aponeurosis plication for correction of acquired upper eyelid ptosis in patients presenting for concomitant cosmetic facial procedures. The medical records of 74 consecutive patients (68 women and six men) who had upper eyelid ptosis correction in conjunction with cosmetic facial procedures from January of 1994 to January of 2000 were reviewed. During this period, 400 endoscopic forehead lifts and 479 face lifts were performed. The correction was performed through an external upper blepharoplasty approach removing an ellipse of skin and orbicularis muscle. Once the orbital septum was opened, a plication of the levator aponeurosis was accomplished by one or more horizontal mattress sutures of 6-0 clear nylon (with the first bite placed at or just medial to the vertical level of the pupil). The average follow-up period was 14 months. Long-term correction of the ptosis was excellent. The complications were minor, with the most common occurrence being asymmetry. Revisions were performed on only four patients. Correction of ptosis can be performed safely and effectively in conjunction with periorbital and facial rejuvenation. The technique described is simple, reliable, and reproducible.     

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.     

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.     

Early release of third-degree eyelid burns prevents eye injury

Burns to the eyelids occur in more than 20 percent of flame injuries and can lead to ocular damage and even blindness. Burn wound contracture can cause ectropion of the eyelid, resulting in exposure keratitis, corneal ulcers, and conjunctivitis. At our hospital, early eyelid release and grafting has made a significant difference in the long-term outcomes of third-degree eyelid burns; however, the question of just how early eyelid release and grafting should take place is an unresolved issue. Fifty-seven children with third-degree eyelid burns were reviewed; 17 had eyelid release within 7 days of receiving eyelid burns and 40 had a delay in eyelid release of more than 7 days after injury. Analysis was by chi-square with the Yates continuity correction or Fisher's exact test when appropriate. Corneal ulcers developed in 2 of 17 of the early eyelid release of third-degree burns, compared with 25 of 40 delayed releases (p = 0.001), exposure keratitis in 3 of 17 early releases, and 30 of 40 in delayed release (p = 0.000); conjunctivitis was identified in 1 of 17 early releases and 14 of 40 delayed eyelid releases (p = 0.025). Release of eyelid burns within 7 days of injury can prevent the development of exposure keratitis, progressive conjunctivitis, corneal ulceration, and the need for corneal surgery. We suggest that early release and grafting should be the treatment of choice for children and young adults with third-degree burns to the eyelids.     

Full-thickeness anterior blepharotomy and transpalpebral fat decompression in Graves' orbitopathy

A chief morbidity of Graves eye disease is eyelid retraction and exophthalmus. Transpalpebral orbital fat removal accomplished with full thickness anterior blepharotomy was performed in 4 patients (5 orbits). Preoperative and postoperative ocular exposure symptoms, visual acuity, upper eyelid retraction and proptosis were evaluated. In all 5 operated orbits preoperative symptoms resolved; good results were achieved from the functional and cosmetic point of view. Full-thickness anterior blepharotomy combined with fat decompression is a safe and effective surgery for patients with upper eyelid retraction and exophthalmus due to enlarged orbital fat compartment.     

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.     

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."     

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.     

Reconstruction using a three-dimensional orbitozygomatic skeletal model of titanium mesh plate and soft-tissue free flap transfer following total maxillectomy

The surgical strategy for maxillary reconstruction after maxillectomy has yet to be standardized. The authors developed a technique using a three-dimensional orbitozygomatic skeletal model of a titanium mesh for skeletal reconstruction after maxillectomy. From May of 1996 to September of 2000, 18 patients underwent reconstruction using the titanium mesh model in conjunction with a soft-tissue free flap following total maxillectomy for a maxillary malignancy. The soft-tissue free flap was conventional and consisted of two skin paddles to the maxillary defect. One skin paddle became the lateral nasal wall and the other was used to close the palatal defect. After modeling, the titanium mesh plate was implanted between the orbital contents and the upper edge of the free flap to lie over the front of the flap. The model was fixed to the residual zygoma laterally and to the nasal or frontal bone medially. The palatal skin paddle was anchored by three or four dermal stitches to the bottom edge of the titanium mesh to create a concave neopalate that allowed the patient to wear a denture. Thirteen of 18 patients who underwent implantation had good facial appearance and oral function. This procedure prevented lagophthalmos, facial deformity, and sagging of the palatal skin paddle caused by gravitational force. Five patients (27.8 percent) developed exposure or infection of the implant and lost the benefit of having the prosthesis. However, treatment did not require total removal of the implant. Maintaining adequate tissue volume during soft-tissue transfer on either side of the mesh plate may minimize the complication rate. Titanium mesh implantation for skeletal reconstruction after maxillectomy avoids the need for bone grafting and may be especially beneficial in fragile or aged patients.     

Long-term survival of corneal allografts is dependent on intact CD1d-reactive NKT cells

BALB/c mice that tolerate the allogeneic grafts develop allogeneic-specific anterior chamber-associated immune deviation. Because CD1d-reactive NKT cells are essential for anterior chamber-associated immune deviation, we postulated that the survival of C57BL/6 (B6) cornea graft in BALB/c mice was also dependent on CD1d-reactive NKT cells. The B6 corneal graft rejection rate in BALB/c vs Jalpha281 knockout (KO) mice, which lack NKT cells, was measured. While there were no difference in the early phase of rejection, the survival rates at 12 wk after grafting for BALB/c and Jalpha281 KO mice were 50 and 0%, respectively. Because anti-CD1d mAb abrogated the corneal graft survival in the wild-type mice we concluded that CD1d-reactive NKT cells were essential for graft survival. Moreover, allospecific T regulatory (Tr) cells correlated with acceptance of B6 grafts in BALB/c mice, and the adoptive transfer of these allospecific Tr cells to Jalpha281 KO mice allowed a 50% survival rate of B6 cornea grafts. In conclusion, CD1d-reactive NKT cells are required for induction of allospecific Tr cells and are essential for survival of corneal allografts. Mechanisms that contribute to cornea graft acceptance may lead to new therapies for improvement in graft survival in high-risk corneas and other transplanted tissues and grafts.     

RADIATION THERAPY IN DISEASES OF THE EYE

Because of the wide variety of x-rays now available, selectivity is possible and important in treatment of diseases of the eye. By the use of short-range radiation, newly developed eye shields and the insulation of the eyelid itself, and by careful angulation of the beam, the desired irradiation can be given where it is needed without injury to surrounding tissues. The authors have found the 50 kv x-ray unit to be the most reliable and adaptable for most circumstances.The skin of the eyelid reacts to irradiation more sensitively than other tissues. The cornea reacts with keratitis and sometimes intractable ulceration. The iris, uveal tract and retina are less seriously affected.At the University of California Hospital irradiation has been found satisfactory for treatment of corneal ulcer, keratitis, pterygium, certain types of conjunctivitis, episcleritis, corneal vascularization, iritis, uveitis, and hemangioma. Irradiation may be of great benefit in absolute glaucoma with pain and blindness. Of 42 patients with carcinoma of the eyelid treated between 1935 and 1946, 27 had no recurrence in five years, 5 had recurrence, 7 died of other causes and follow-up was incomplete on 3. Good cosmetic result was usually achieved. No recurrence has been observed in 22 patients treated since 1946. Irradiation has been used with success in other kinds of cancer of the eye structures.     

Lateral canthal anchoring

LEARNING OBJECTIVES: After studying this article, the participant should be able to: 1. Understand the principles involved in canthal support for patients undergoing cosmetic and reconstructive surgery. 2. Understand the variations in surgical techniques required to perform canthal anchoring in differing patients. 3. Describe the significance and techniques of canthal anchoring (canthoplasty and canthopexy) as they relate to cosmetic and reconstructive lower lid surgery. 4. Describe the effect of canthal anchoring on the function of the upper and lower lids and eyelid fissure shape. Any surgeon performing cosmetic or reconstructive surgery procedures on the lower lid or midface through the lower lid should be comfortable with canthal anchoring procedures. Appropriate canthal anchoring is effective in preventing postoperative lower-lid malposition, in ensuring eyelid closure, and in improving or maintaining proper eye shape. In many patients, a canthopexy (nonlysis canthal anchoring) is effective. However, in patients with significant horizontal laxity, cantholysis with appropriate lid shortening is required. It should be remembered that canthal anchoring, no matter how well performed, will not prevent severe lower-lid complications in cases of over-resection of lower-lid skin and of poorly performed midface procedures that do not support the lower lid and cheek.     

Secondary correction of unsatisfactory blepharoplasty: removing multilaminated septal structures and grafting of preaponeurotic fat

Oriental blepharoplasty, commonly known as a "double eyelid operation," is the most frequently practiced cosmetic procedure in Orientals, who have probably become more fold conscious because of social westernization and an influx of Caucasians into their society. Anatomically, the upper eyelids of an Oriental are considerably different from those of a white person, and nearly half of Orientals have single eyelids. When performing blepharoplasty, an appropriate design and operative technique must be carefully selected, taking into consideration the anatomical characteristics of Koreans to obtain an aesthetically pleasing result. However, the incidence of complications is high. Patients who are faced with unsatisfactory results are often perplexed by the fact that such a commonly performed procedure could have a very high rate of dissatisfaction and that an improvement is not easy. An unfavorable result need not imply a postoperative complication, but only that the result is not acceptable to the patient, whose goal may not be based on good aesthetic principles. The most common sources of dissatisfaction are postoperative asymmetry and high placement of the lid fold. From 1991 to 1998, secondary blepharoplasty was performed on 72 patients by slitting transversely, removing the multilaminated septal structures exposed to the previous operative scar, spreading the preaponeurotic fat that extruded, and removing the septal structures into a space where the scar was eliminated to prevent secondary adhesion. The average age of the patients was 26.5 years, and the average follow-up period was 2 years. No remarkable complication was encountered after operation with this method, and the desired aesthetic improvements were achieved in the majority of the patients.     

A New Surgical Technique for Polysyndactyly of the Toes without Skin Graft

Reconstruction for polysyndactyly of the toes aims at cosmetic improvement. A previous method that uses a skin graft has inherent disadvantages of mismatched pigmentation between the graft and the surrounding skin and scar formation at the donor site. The authors' new improved surgical technique for the treatment of polysyndactyly of the toes does not require a skin graft and therefore avoids these problems. The authors designed a subcutaneous flap from the distal portion of a rectangular flap of skin from the dorsal side of the interdigital webbing and moved the former flap to the sidewall of the base of a toe. Both flaps are the same size; therefore, an interdigital space had to be of sufficient size to accommodate both of them. To ensure an adequate blood supply to the flap, careful handling of the subcutaneous flap is essential for success. This procedure can apply to polysyndactyly of the fourth, fifth, and sixth toes when the fourth and fifth toes adhere over the distal side of the distal interphalangeal joint and when the skin on the dorsal side of the fifth toe, regarded as the excessive one, is at lease twice the size of the dorsal rectangular flap. Ten patients with polysyndactyly of the toe were treated with this method. Aesthetically good results were obtained.
