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.     

Frontalis muscle advancement: a dynamic structure for the treatment of severe congenital eyelid ptosis

Forty-two consecutive patients have had severe eyelid ptosis corrected by intraorbital frontalis flap advancement as a motor unit to substitute for the function of the levator muscle. This technique has avoided the need for the linking structure necessary in the standard frontalis sling approach and has improved the direction of pull to more closely mimic that of a normal levator. This simple technique includes elevation of the innervated frontalis muscle flap and the creation of a pulley near the insertion of the orbital septum at the superior orbital rim, which redirects the lid movement along the surface of the globe rather than lifting it from the globe's surface toward the brow. This type of displacement is produced because the muscle is directed posteriorly by the pulley, so that it conforms to the plane of the levator aponeurosis all the way down to the tarsal plate. In addition, to improve the remaining function of the levator muscle (if any) and to facilitate voluntary positioning of the eyelid, the levator aponeurosis is shortened by plication. Symmetry is created by intervention on the contralateral eyelid to provide symmetrical supratarsal creases.     

Levator advancement technique for eyelid ptosis

There have been many procedures advocated for the treatment of eyelid ptosis. The technique advocated in this paper consists of careful dissection and identification of anatomic landmarks, including preaponeurotic fat, Whitnall's superior transverse ligament, and the vertically oriented blood supply of the levator muscle. The attachment of the levator muscle into the cephalad portion of the levator muscle into the cephalad portion of the levator aponeurosis can be identified and easily dissected in order to perform the procedure of detachment and advancement to the tarsal plate. This procedure for ptosis has been successful in management in moderate to severe ptosis and in some cases has actually increased the muscle function, thereby enhancing the result. In this technique, the full length of levator muscle remains, so maximum excursion is achieved postoperatively. In addition, this surgical approach may be utilized for levator-lengthening procedures in cases of thyroid exophthalmus or overcorrected ptosis simply by performing the reverse procedure of detachment and insertion of a spacer based on the same ratio. Good results have been achieved in over 20 patients, with the exception of two patients who had absent to poor function and in whom undercorrection was present postoperatively.     

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 double-eyelid operation without supratarsal fixation

Among the considerations in the formation of the double eyelid, two factors are considered to be important. They are the levator insertion into the skin and the amount of soft tissue between the levator aponeurosis and the skin. The author assumes that the amount of soft tissue may be more importantly related to forming the double eyelid than the levator expansion. Based on this assumption, the author undertook a modified operation to create the double eyelid by removing excessive soft tissue without any fixation to the levator aponeurosis or the tarsal plate.     

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.     

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.     

Surgical treatment of thyrotoxic exophthalmos

Conservative treatment of thyrotoxic exophthalmos has not given satisfactory results. Our observations, modifications of the standard surgical technique, and the results of orbital decompression for this condition are presented. Through a transverse incision close to the lower eyelid margin, the floor and the lateral orbital wall are explored. The posterior part of the orbital floor and the zygomatic part of the lateral orbital wall, as well as the periorbital fat, are removed. Through an incision made over the medial margin of the orbit, the medial orbital wall is explored and its ethmoidal part is removed. By the same approach, further retrobulbar fat is removed. Through an upper eyelid incision, fat is removed from the eyelid region and the levator aponeurosis is divided. This produces satisfactory symmetrical decompression of the orbit with good correction of exophthalmos and a significant decrease in the signs and symptoms of this condition.     

Surgical anatomy of the levator veli palatini: a previously undescribed tendinous insertion of the anterolateral fibers

The purpose of this study was to describe the previously unreported tendinous insertion of the anterolateral fibers of the levator veli palatini (levator) and discuss possible implications for levator function and cleft palate repair. The velopharyngeal anatomy in normal adult cadavers was studied, with histologic confirmation of anatomical findings. These findings were compared with a more limited study of levator anatomy in cleft palates at the time of intraoperative muscle dissection. Just before entering the velum, the levator divides into two parts. The smaller bundle of muscle fibers (anterolateral part) runs anteriorly, close to the lateral pharyngeal wall, and inserts into the palatine aponeurosis through a number of fine tendons. The main part of the muscle runs medially into the velum, where it fans out and forms the levator sling with the contralateral levator. The possible function of the anterolateral part of the levator is discussed. Inadequate release of the tendinous insertions at the time of palate repair may tether the levator anteriorly and compromise muscle retropositioning or may result in splitting of the levator, so that only part of the levator is retropositioned.     

Evaluation of the Results of Surgery to Correct Congenital Ptosis of the Upper Eyelid

Experience in the surgical correction of congenital ptosis in 203 children operated on at The Hospital for Sick Children, Toronto, demonstrated that because of the different types and complicated nature of ptosis the choice of operation in each case is most important. Occasionally ptosis is associated with other anomalies such as blepharophimosis, epicanthus, and the jawwinking syndrome, which further complicate its repair. Although the results in complicated cases are not perfect, these children should be given the benefit of surgery, since almost all can be greatly improved. The best time for surgery is after three years of age but before the child starts school. If adequate levator action is present, shortening this muscle is the operation of choice. If levator function is poor, the lid is elevated by the frontalis muscle and fascia lata. Achievement of symmetry in the position of the lid and width of the palpebral fissure is the key to real success in ptosis surgery.     

Disinsertion of the levator aponeurosis from the tarsus in growing children

To confirm when the levator aponeurosis is disinserted and how the disinsertion is compensated for in growing children, the earliest and latest photographs of the same children were the subjects of a retrospective comparative study regarding upward displacement of the superior palpebral crease and the eyeball in the palpebral fissure. Ninety-four children (48 boys and 46 girls) were selected from 615 patients with cleft lip and palate who were followed for more than several years at our outpatient clinic and whose 58,000 photographs were digitized. The earliest and latest photographs of the patients were taken in primary gaze position; the former, taken at less than 3 years of age, and the latter, taken at more than 6 years of age, were selected for this study. The intervals between the two photographs ranged from 3 to 14 years (mean, 9.61 years; SD, 3.11). The superior palpebral crease moved upward parallel with the growth of the children (p < 0.0001) as well as with the length of the growth period (p = 0.0141). The lower eyelid did not move downward (p < 0.0001). The eyeball also displaced upward parallel with growth (p < 0.0001) and with the length of the growth period (p = 0.0302). The more the superior palpebral crease was displaced upward, the more the eyeball was displaced upward (p = 0.0005). The levator aponeurosis may be likely to disinsert from the tarsus in growing children, thus requiring compensatory, excessive contraction of the levator muscle, which may cause upward displacement of the superior palpebral crease. Subsequently, excessive contraction of the superior rectus muscle in conjunction of the levator muscle may rotate the eyeball upward, which may incline the head. When the head is not inclined in the primary gaze position, compensatory contraction of the inferior rectus muscle to maintain the horizontal visual axis may displace the eyeball upward in the orbit by means of the inferior suspensory ligament of Lockwood.     

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.     

Arterial anatomical features of the upper palpebra

The arterial anatomical features of the upper palpebra were examined in both sides of seven fresh cadavers that had been systemically injected with a lead oxide/gelatin mixture. All specimens were stereoscopically radiographed for analysis of the three-dimensional structure of the arteries and were macroscopically dissected for observation of the relationships between the arteries and the other tissues. Cross-sections were prepared from one specimen and examined histologically. In all cases, there were four arterial arcades in the upper palpebra, namely, the marginal, peripheral, superficial orbital, and deep orbital arcades. Each arcade provided small vertical branches. The vertical branches coursed on both sides of the orbicularis oculi muscle and on both sides of the tarsal plate. From these small vertical branches, fine vessels branched off to the skin, muscle, and tarsal plate. These findings are important for avoiding complications such as bleeding and are useful for designing local flaps, such as switch flaps, for reconstructive surgical procedures.     

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.     

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.

Orbitoblepharophimosis syndrome: a 16-year perspective

The orbitoblepharophimosis syndrome is a congenital malformation of the orbitopalpebral region. It is an autosomal-dominant condition typified by palpebral and orbital phimosis, ptosis, epicanthus inversus with telecanthus, and enophthalmia. It has three forms: minor, major, and extreme. It is a rare malformation affecting both sexes. The gene responsible is 3q21-24. Surgical treatment involves three to four operations: orbital remodeling by burring and grafting (intraorbital and extraorbital), epicanthus correction, and ptosis operation. Results varied depending on the severity of the form and the quality of the tissues. The authors present a series of 50 patients who were treated for this syndrome over the past 16 years.     

One-stage repair of blepharophimosis

Congenital blepharophimosis is a congenital anomaly characterized by abnormalities in the area of the eyes, including bilateral ptosis, shortening of the horizontal fissure of the lid, expansion of the intercanthal distance, and epicanthus inversus. The condition is subject to autosomal-dominant heredity and is said to occur more frequently in Orientals than in Occidentals. Over the past 9 years, we have surgically treated 11 cases of congenital blepharophimosis using a procedure in which levator resection and medial canthoplasty are performed in one stage. It has been commonly believed that when levator resection and medial canthoplasty are performed at the same time, tension in the eyelid becomes too strong to achieve favorable results; therefore, the standard procedure has been to divide the operation into two stages. In all 11 cases we experienced, however, it was possible to obtain good results with a single-stage operation.
