Facial paralysis can result in serious keratopathy because of corneal exposure and inadequate lacrimation. Thirty-seven patients underwent thirty-eight gold weight upper lid implants to rehabilitate paralysis of the eyelid from various causes. When indicated, implantation was combined with lower lid ectropion repair, medial canthoplasty or brow lift. Because of encouraging results in patients with longstanding facial paralysis, "early" implantation (within 1 month of paralysis) was offered to patients with severe lagophthalmos in whom (1) a severe neural injury was documented at the time of transtemporal surgery or (2) delayed, incomplete return of function was expected. Gold weight implantation resulted in excellent eyelid closure, protection, and cosmesis. There were no infections or extrusions. Lagophthalmos and exposure keratitis resolved or were significantly improved in all patients, and most were able to dispense with eyedrops and salves. Visual acuity improved in 95% of patients--a benefit even those without preoperative keratitis often achieved. A mild worsening of one patient's pre-existing astigmatism developed, which resolved after reimplantation with a lighter weight. The implant is easily removed from those patients who, having undergone early implantation, eventually recover adequate function. Gold weight loading has become our procedure of choice for eyelid rehabilitation.

A total of 136 injections was given to 83 patients for strabismus (99 injections), blepharospasm (29 injections), and spastic entropion (eight injections). All four patients with entropion experienced temporary benefits and early recurrence; one injection resulted in temporary paralytic ectropion. Two of 13 patients treated for blepharospasm developed transient bilateral blepharoptosis. Temporary and related sequelae of extraocular muscle injection included one periocular hemorrhage, one total ophthalmoplegia, and a 44% incidence (29 of 66 patients) of blepharoptosis, which in two patients lasted more than six months. Within three days of injection one patient developed homolateral acute herpes simplex keratitis and a second died of an acute myocardial infarction. No causal relationship for these events has been established.

We present our experience with correction of paralytic ectropion in 10 patients with a composite chondrocutaneous graft obtained from the scapha of the ear. This large composite graft is sutured to the tarsal plate to support the lower lid. It prevented exposure keratitis in all patients. Two patients needed minor secondary revisions of the corners of the cartilage graft. The donor defect healed satisfactorily without deforming the ear. There were no other complications and no other lid or visual problems. At 3-year follow-up, the results thus far appear long lasting.

The authors reviewed 44 tarsoconjunctival grafts performed from 1983 to 1993 to determine the nature and severity of complications related to these grafts. Follow-up ranged from 3 weeks to 10 years, with a mean of 23 months. The complications were categorized as none, minor, or major. A complication was deemed major if it required a second surgical procedure for treatment. Eleven percent (5/44) of patients had major complications, including marked upper lid retraction after upper lid reconstruction (1), wound dehiscence (2), cicatricial ectropion (1), and excessive lower lid laxity (1). Seventy-three percent (32/44) of patients had minor complications. Minor complications included trichiasis (5), notching of the donor and/or recipient lid margin (9), mild lid retraction (3), contour deformity (2), granuloma (2), prolonged edema or erythema (4), symblepharon (1), mild ectropion (2), punctate keratitis (1), minimal ptosis (1), and epiphora (1). Sixteen percent (7/44) had no complications. Despite the frequent minor complications and the occasional major complications, the use of free tarsoconjunctival grafts remains a valuable procedure in the surgeon's armamentarium for reconstruction of major eyelid defects. Knowledge and early recognition of the possible complications may result in better patient care.

Botulinum toxin has become the initial treatment of choice for the management of essential blepharospasm, hemifacial spasm and other craniocervical dystonias. Numerous studies have confirmed a 90% to 95% response rate. Although a number of common side effects have been reported, the occurrence and incidence of rare local complications remains poorly understood. More importantly, the acute and chronic distant effects of botulinum toxin have not been clearly elucidated. A better understanding of such effects is essential if clinicians are to appropriately advise patients on the use of this therapeutic modality. This article is based on the Duke University experience in the management of over 500 patients with craniocervical spasm disorders, combined with a review of the published literature. These disorders include essential blepharospasm, oromandibular dystonia, hemifacial spasm, and torticollis. The incidence of side effects following more than 6000 treatments with botulinum toxin is presented. Pertinent research relating to the causes of these complications is also reviewed. The most common complications of treatment with botulinum toxin are related to acute local effects resulting from chemodenervation. The most important clinical effect in this group is weakening of the levator muscle resulting in ptosis, and the corneal consequences of lagophthalmos. The latter includes exposure keratitis, dry eyes, blurred vision, and hypersecretion epiphora. Less common local effects include facial numbness, diplopia, and ectropion. Some distant effects are being observed with increasing frequency. These include pruritus, dysphagia, nausea, and a flu-like syndrome. Most significant, however, are the rare reports of generalized weakness and the documentation of EMG abnormalities distant to the site of toxin injection. This has been seen with injections for both blepharospasm and torticollis. Until further studies on the long-term distant complications of botulinum toxin are available, it is recommended that patients receive as few life-time doses of toxin as possible, consistent with adequate management of their spasms. The practice of reinjecting patients routinely every three months, or at the first return of mild spasms should be discouraged.

Lower eyelid malposition is the most common long-term complication following transcutaneous lower eyelid blepharoplasty. The malposition may include rounding of the lateral canthal angle, lower eyelid retraction with inferior scleral show, or frank ectropion. The result is cosmetically unacceptable and may be associated with tearing, irritation, and other exposure keratitis symptoms. Multiple factors, including lower eyelid laxity, shortage of skin, and scarring of the middle lamella, may be responsible for this malposition. A systematic examination of the lower eyelid, as presented, helps to assess the degree to which each of these factors is responsible for the malposition. Patients with the most severe degree of lower eyelid malposition generally have middle lamella scarring. If this abnormality is not addressed, lower eyelid procedures aimed at correcting the malposition are doomed to failure. In the presence of significant middle lamella scarring, a spacer is required to provide vertical height and stiffness to support the lower eyelid following release of the cicatrix. A systematic approach aimed at addressing the underlying abnormalities was developed. In patients with significant middle lamella scarring, hard palate mucosa grafts were used as spacers in 29 eyelids (17 patients). A lateral canthotomy and transconjunctival incision allow access to the scarring in the lower eyelid retractors and septum. After careful release of all cicatrix, a hard palate mucosa graft is inserted between the lower border of the tarsal plate and the recessed conjunctiva, lower eyelid retractors, and septum. Horizontal lower eyelid laxity, when present, is corrected by performing a lateral tarsal strip. Most patients do not have a true deficiency of the anterior lamella (skin and orbicularis oculi muscle). When a moderate amount of anterior lamella deficiency is present with significant scarring of the middle lamella, the technique we describe allows correction of the lower eyelid malposition without a skin graft. After a follow-up interval of 6 to 30 months (mean 14 months), excellent results were obtained in all eyelids. Complications included corneal abrasions in two eyes before routine use of bandage cornea contact lenses at the end of surgery and a secondary bleed from the roof of the mouth in one patient. Palate mucosa closely resembles tarsus and provides excellent vertical support to the eyelid. It is stiff enough to maintain eyelid contour without causing a cosmetically unacceptable bump. Tissue can be obtained with ease. The technique, as described, addresses the underlying causes of lower eyelid malposition and gives excellent functional and cosmetic results.

Exposure keratitis can lead to infectious keratitis, corneal perforation, blindness and disfigurement. Chronic exposure of the cornea can occur following facial burns that cause eyelid ectropion. This complication can be difficult to diagnose in the unconscious patient. Five patients have undergone lid ectropion release to 11 eyelids in the early postburn period over the past 5 years. One patient required repeat release. Full-thickness skin grafts were used for the lower eyelid and no graft failure occurred. Operations were performed between 30-50 days postburn. Plastic wrap was used in one patient as a temporary dressing to maintain corneal hydration until surgery could be performed. All the patients were noted to have exposure keratitis on ophthalmological review. Patients most at risk are those with large area burns that include the face, who require prolonged intensive care support. It is important to look out for the development of eyelid ectropion, which should be corrected when first diagnosed to prevent disabling, sight-threatening 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.

Chemical burns of the eyelids are common, and this may lead to ocular damage. A direct insult of the eyes that result in permanent damage, is rare in facial burns. The majority of the chemical burns of eyelids are partial-thickness that heal spontaneously in 1 week. Whereas, 10 percent are full-thickness burns that require release of contractures and grafts. Wound contracture can cause ectropion of the eyelid, resulting in exposure keratitis, conjunctivitis, corneal ulcers, perforation, and even blindness. At our departments, thirteen patients with 28 chemical burns of eyelids of third-degree, were reviewed. The eyelids had burns wounds with granulation and necrotic tissue. All patients had severe cicatrical ectropion. The eyelids were released with incisions running along the eyelid margin, down to the orbicularis muscle, including the distal part of the levator palpebrae superioris muscle, when necessary. To cover the resulting defects, we use generous full-thickness skin grafts, if available, for both the upper and lower eyelids. Rarely has a tarsorrhaphy been required, and properly constructed dressing provides satisfactory eyelid margin immobilization and conjunctival hygiene. Eighteen full-thickness grafts in 10 patients are reported 8 to 12 weeks after grafting. In seven eyelids, 3 patients developed ectropion and required reconstruction of the eyelids. Our series demonstrates that the early grafting of eyelid burns with full-thickness grafts, can prevent the development of recurrent cicatrical ectropion. Split-thickness grafting should be limited to cases where we can not find the hairless donor site for full-thickness skin grafts.

Management of postburn cicatricial ectroption of the upper lid is always a challenge for the oculoplastic surgeon, as they are often associated with exposure keratitis and ulceration. Traditionally, split thickness grafts have been described for upper lid reconstruction and tarsorrhaphies have been discouraged. We present a case of corneal ulceration associated with postburn cicatricial ectropion presenting 10 years following the initial trauma. The patient underwent full thickness skin grafting and tarsorrhaphy to release the ectropion with resolution of corneal ulceration. We believe that full thickness skin grafts and tarsorrhaphy are effective in correcting upper lid cicatricial ectropion, without functional compromise.
