Long-term results of frontal lobe suspension in children with congenital dystrophic ptosis

Long-term results achieved by our own operative technique in children with congenital dystrophic ptosis, with frontal muscle lobe shaping with or without shaping of corrugator muscle lobe attached to the tarsal plate, are presented. Data on 146 patients with congenital dystrophic ptosis operated on during the 1984-1998 period at Zagreb University Hospital Center were retrospectively analyzed. Postoperative success was defined as a situation with eyes open in which 1) upper eyelid covers the cornea at 12 o'clock position by 1-2 mm; 2) there is a good contour of the eyelid margin; 3) there is no lagophthalmos; and 4) there is symmetry with the other eye. Immediate re-operation due to undercorrection was required in 26 of 146 (18%) patients. Upon re-operation, 133 (91%) patients met the criteria for successful outcome at 6 months, 124 (85%) at one year, and 121 (83%) at 5 years. Correction of congenital dystrophic ptosis using a shaped frontal/corrugator lobe is an efficient and safe procedure ensuring long-lasting success.     

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.     

Correction of lower eyelid ptosis in the anophthalmic orbit with an autogenous ear cartilage graft

We describe the correction of lower eyelid ptosis in patients with an anophthalmic orbit, using ear cartilage grafts. This procedure has been particularly useful in the scarred or previously reconstructed lower 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."     

Temporary management of upper lid ptosis, lid malposition, and eyelid fissure asymmetry with botulinum toxin type A

During the past 10 years the primary focus for the aesthetic use of botulinum toxin has been directed to the treatment of dynamic facial lines. This agent has been shown to be very effective for the improvement of facial shape. The use of botulinum toxin type A for the correction of a variety of presentations of facial asymmetry has also been well established. The general principles regarding the counter-effects of facial muscle protagonists and antagonists and their potential effects on the position of facial soft-tissue regions apply here as well. Twenty-two patients received botulinum toxin type A for the temporary treatment of mild to moderate unilateral upper eyelid ptosis and aesthetic improvement of lower eyelid position, with favorable results. Although commonly related to a rare yet feared adverse consequence from the inappropriate application of botulinum toxin, its application for the treatment of upper eyelid ptosis, eyelid position, and other lid fissure asymmetries for aesthetic improvement is presented.     

A simple approach to identification of the levator aponeurosis in the correction of eyelid ptosis

A new method of approach for the correction of upper eyelid ptosis is described. This involves both conjunctival and skin incisions. It allows for greater ease of identification of the levator aponeurosis and appears to facilitate in the identification of Müller's muscle. Although advised for all patients requiring ptosis correction, it is particularly recommended in those patients in whom the eyelids are involved with extensive posttraumatic scarring.     

Frontalis Muscle Flap Suspension for the Correction of Congenital Blepharoptosis in Early Age Children

Background

We aimed to report our successful use of frontalis muscle flap suspension for the correction of congenital blepharoptosis in early age children.

Methods

This retrospective study included 61 early age children (41 boys, 20 girls) with an average age of 6 years (range, 3–10 years) with congenital blepharoptosis who received surgery during the period from March 2007 to January 2011. There were 39 cases of unilateral blepharoptosis and 22 cases of bilateral blepharoptosis, thus a total of 83 eyes were affected. If patient had bilateral blepharoptosis, both eyes were operated on in the same surgery. Patients were followed for 3 months to 5 years. The procedure was performed without complications in all cases.

Results

The postoperative healing grade was good in 81 eyes (97.6%); the correction of blepharoptosis was satisfactory, the double eyelid folds were natural and aesthetic, the eyelid position and the curvature were ideal, and the eyes were bilaterally symmetrical. The postoperative healing grade was fair in 2 eyes (2.4%); blepharoptosis was improved compared with that before surgery. At discharge, lagophthalmos was noted in 10 eyes of which 4 cases resolved by the last follow-up. The remaining 6 cases were mild. Eleven eyes received reoperation for residual ptosis after the first surgery. The curvature of the palpebral margin was not natural in 4 eyes. These unnatural curvature possibly was caused by an excessively low lateral fixation point or postoperative avulsion.

Conclusion

Frontalis muscle flap suspension under general anesthesia for the correction of congenital blepharoptosis in early age children can achieve good surgical results.     

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.     

Experience with the modified Putterman procedure

Results using our modification of the Putterman procedure are reported in 43 eyelids. The procedure is very effective in cases of minimal to moderate eyelid ptosis (3 mm or less) and in the presence of normal levator function. The patients, following a thorough clinical evaluation, are tested using 2.5% phenylephrine eyedrop solution, which acts as an extremely useful prognostic indicator. Depending on the degree of ptosis and the response to phenylephrine, 6 to 9 mm of combined Müller's muscle and conjunctiva is resected using a specially designed clamp under local or attended local anesthesia (no tarsal plate is resected). The incision is repaired using a running 6-0 Prolene horizontal mattress technique, and the ends are brought up through the skin and tied over the tarsal plate. In the treatment of 43 eyelids, with the exception of one slight overcorrection, there were no complications encountered with this simple procedure. Excellent results can be expected in properly selected patients, and recovery time is minimal. Our success in the last 4 years with this modified procedure allows us to strongly recommend it for the correction of mild to moderate ptosis when there is an acceptable response to phenylephrine.     

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.     

Kinematic and Diffusion Tensor Imaging Definition of Familial Marcus Gunn Jaw-Winking Synkinesis

Background

Marcus Gunn jaw-winking synkinesis (MGJWS) is characterized by eyelid ptosis, which disappears during jaw movement. Familial MGJWS is an extremely rare condition. Some authors suggested that MGJWS is due to neural misdirection in the brainstem whereas others suggested that aberrant reinnervation or ephapse may be responsible for synkinetic activity. Pathogenesis of this condition is therefore still unclear.

Methodology/Principal Findings

To investigate pathogenetic mechanism in familial MGJWS we performed neurophysiological (EMG, Blink Reflex, Recovery cycle of the R2 component of the blink reflex, Masseter inhibitory reflex, BAEPS and kinematic analysis) and neuroradiological (MRI, Diffusion Tensor Imaging) investigations in a member of a multigenerational family with autosomal dominant Marcus Gunn jaw-winking synkinesis (MGJWS). Kinematic analysis of eyelid and jaw movements disclosed a similar onset and offset of the eyelid and jaw in both the opening and closing phases. The excitability of brainstem circuits, as assessed by the blink reflex recovery cycle and recovery index, was normal. Diffusion Tensor Imaging revealed reduced fractional anisotropy within the midbrain tegmentum.

Conclusions/Significance

Kinematic and MRI findings point to a brainstem structural abnormality in our familial MGJWS patient thus supporting the hypothesis of a neural misdirection of trigeminal motor axons to the elevator palpebralis muscle.     

Involutional entropion: a simple and stable repair

A simple technique for repair of involutional entropion is described. A 4 x 20 mm strip of cartilage is removed from the concha of the ear and placed in the lower lid, deep to the orbicularis muscle. Over the past 6 years, I have performed this procedure on 15 patients. Fourteen patients had an excellent result; one patient required a secondary lateral wedge resection. There have been no recurrences. The tarsal plate of the lower eyelid appears to soften and shrink with advancing age. As the tarsus shrinks, the lid becomes less rigid and the margin tends to roll inward. Creating a neotarsus out of ear cartilage provides a simple and stable repair for involutional entropion because it restores the structural rigidity of the lower lid. The operative procedure is technically simple. Its long-term effectiveness confirms the view, not widely held, that one primary cause of involutional entropion is a shrunken and atrophic tarsal plate.     

Surgical correction of eyelid disfigurement in a stumptailed monkey (Macaca arctoides)

Self-aggression in an adult male stumptailed monkey (Macaca arctoides) resulted in severe lower eyelid distortion, conjunctivitis and epiphora. The behavior ceased with a change in environment, but the eyelid defect, conjunctivitis and epiphora persisted, requiring corrective surgery. Surgical correction was partially successful, although the animal died due to unrelated medical problems before final correction could be accomplished.     

Upper eyelid ptosis repair after cataract extraction and the importance of Hering's test.

Blepharoptosis is a well-documented complication of cataract extraction and other ocular procedures. Few authors have described the surgical findings and outcomes of postcataract blepharoptosis repair. The authors present a review of the causes of postcataract blepharoptosis with emphasis on both clinical findings and recommendations for treatment on the basis of their experience with 13 eyelids in eight patients over the past 10 years. They found that all patients had either partial or total disinsertion of the levator muscle from the tarsal plate. Of the eight patients in this series, five had bilateral blepharoptosis after bilateral cataract extraction. Although a multifactorial cause for postcataract blepharoptosis is commonly assumed, the authors propose that the mechanical forces of intraoperative traction on the levator aponeurosis during cataract surgery are the primary cause. This is further supported by their operative findings in the five patients who developed bilateral ptosis after bilateral cataract extraction. All eyelids in this series were repaired by levator muscle advancement and attachment to the tarsal plate with favorable outcomes and no recurrences during a 1-year follow-up. The importance of Hering's phenomenon of equal innervation is also discussed as it applies to bilateral and to apparent unilateral blepharoptosis. The authors propose "Hering's test" as an important indicative study in the preoperative evaluation of all patients with eyelid ptosis.     

Sphingosine 1-Phosphate Receptors Are Essential Mediators of Eyelid Closure during Embryonic Development

The fetal development of the mammalian eyelid involves the expansion of the epithelium over the developing cornea, fusion into a continuous sheet covering the eye, and a splitting event several weeks later that results in the formation of the upper and lower eyelids. Recent studies have revealed a significant number of molecular signaling components that are essential mediators of eyelid development. Receptor-mediated sphingosine 1-phosphate (S1P) signaling is known to influence diverse biological processes, but its involvement in eyelid development has not been reported. Here, we show that two S1P receptors, S1P₂ and S1P₃, are collectively essential mediators of eyelid closure during murine development. Homozygous deletion of the gene encoding either receptor has no apparent effect on eyelid development, but double-null embryos are born with an “eyes open at birth” defect due to a delay in epithelial sheet extension. Both receptors are expressed in the advancing epithelial sheet during the critical period of extension. Fibroblasts derived from double-null embryos have a deficient response to epidermal growth factor, suggesting that S1P₂ and S1P₃ modulate this essential signaling pathway during eyelid closure.     

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.     

Transcoronal blepharoplasty.

Some of the patients requesting blepharoplasty have a combination of excessive eyelid fat and brow ptosis but little or no dermatochalasis. Coronal brow lift, combined with transcoronal fat removal, serves these patients well. The prelevator fat pocket is easily entered from above by incising the periosteum of the anterior orbital roof just inside the orbital rim. Since the orbital septum and anterior lamella of the eyelid rim remain undisturbed, the result appears natural. Contraindications to the procedure include significant medical pocket fat and hair patterns that would exclude a coronal or hairline incision. Two complications, unilateral ptosis and unilateral chemosis, were temporary and totally reversible. Minor changes in the procedure have prevented the recurrence of these problems.     

Mechanisms of extraocular muscle injury in orbital fractures

The gross and microscopic events that occur after orbital blowout fractures were evaluated to assess the mechanisms of diplopia and muscle injury. Intramuscular and intraorbital pressures were evaluated in experimental animals, in cadavers, and at the time of orbital fracture explorations for repair of orbital fractures in humans. Histologic and circulatory changes, muscle pressure recordings, and operative observations were evaluated. Creation of a compartment syndrome was evaluated to include a histologic evaluation of the orbital fibrous sheath network for the extraocular muscles and the intramuscular vasculature. These experiments and observations do not support the role of a compartment syndrome in ocular motility disturbances because (1) intramuscular pressures were subcritical in both humans and animals; (2) no limiting fascial compartment could be demonstrated; and (3) microangiograms and histologic evaluations did not confirm areas of compartmental ischemic necrosis. Muscle contusion, scarring within and around the orbital fibrous sheath network, nerve contusion, and incarceration within fractures remain the probable causes of diplopia, with the most likely explanations being muscle contusion and fibrosis or incarceration involving the muscular fascial network.
