<strong>Eyelid</strong> <strong>Reconstruction</strong><br />
• Adjacent eyelid skin is the best color match<br />
• Cheek skin is a good match (texture & color)<br />
• Glabellar & nasolabial skin are useful flaps , but<br />
the color& texture match are not always best<br />
16
<strong>Eyelid</strong> <strong>Reconstruction</strong><br />
• Skin graft - if primary closure & local flap<br />
coverage are not feasible<br />
• STSG contract & give poor color match<br />
• Sup. Clavicle FTSG good color match<br />
• Upper inner arm FTSG are hairless and pliable,<br />
color match may not be good<br />
<strong>Eyelid</strong> <strong>Reconstruction</strong><br />
• There are numerous available local flaps:<br />
a- bipedicled Tripier flap<br />

Lower <strong>Eyelid</strong> <strong>Reconstruction</strong><br />
PARTIAL THICKNESS DEFECTS<br />
• Tumor, trauma, or burns<br />
• It could involve skin loss only or skin & muscle<br />
• Enough skin in the adjacent area, primary<br />
closure be possible<br />
18
Lower <strong>Eyelid</strong> <strong>Reconstruction</strong><br />
PARTIAL THICKNESS DEFECTS<br />
• If the defect is horizontal, attempted closure<br />
of a large defect may result in ectropion<br />
• Small defects - skin from both upper lids<br />
• Orbicularis muscle loss - composite muscle and<br />
skin patch from the upper lid<br />
• FTSG from postauricular area<br />
• Excellent color match, heal with some<br />
stiffness - additional support to the lower lid<br />
19
• Relaxed lid margin furnishes poor support and<br />
allow lid eversion postoperatively<br />
• Wedge excision of tarsus and lid margin, the<br />
graft can be placed directly over the closure<br />
with good graft ―take‖<br />
Lower <strong>Eyelid</strong> <strong>Reconstruction</strong><br />
FULL THICKNESS DEFECTS<br />
• Frozen section<br />
• <strong>Reconstruction</strong> can be delayed<br />
20
Direct Closure<br />
30% defects in young patients<br />
Up to 45% in older patients (laxity)<br />
Lateral cantholysis - additional 5 mm<br />
Tarsal defect should be squared<br />
• The excision is vertically oriented in the tarsus:<br />
pentagon shape<br />
• Approximation of the pentagon:<br />
straight lid margin without notching<br />
• The knot must be tied<br />
away from the conjunctiva<br />
to prevent irritation<br />
• The wound is closed in<br />
three layers<br />
21
Direct Closure<br />
Lid Margin Repair<br />
22
The “extensile” approach:<br />
A: ―Tag‖ sutures can be placed in the tarsal margin<br />
under tension to see if closure is possible<br />
B: If direct closure is not possible, exposure and<br />
cantholysis of the lateral canthal tendon to relax<br />
the lateral eyelid<br />
23
Lateral Cantholysis<br />
Split upper and lower canthal tendons<br />
Detach lower limb (upper limb)<br />
Angle skin incision superiorly<br />
Anchor muscle layer to periosteum after<br />
closure of defect<br />
Lateral Cantholysis<br />
24
C: If lateral cantholysis is not adequate for closure,<br />
a skin flap can be designed with the incision<br />
extended onto the cheek or with a ―back-cut‖ of<br />
the flap as shown<br />
• Advancement of this<br />
flap along with rotation<br />
of the conjunctiva<br />
generally allows closure<br />
of defects, in some<br />
cases up to nearly onehalf<br />
of the lower lid<br />
Tenzel Rotational Flap<br />
Semicircular musculocutaneous flap<br />
Defects up to 60%<br />
Flap must arch upward<br />
Fixation of muscle to periosteum<br />
superior to canthal attachment avoids<br />
droop of lid<br />
25
Tenzel Flap<br />
D: If a small cheek advancement is not adequate, a<br />
large cheek flap can be designed and used<br />
• Defects up to complete lower lid loss can be<br />
reconstructed by this technique<br />
• Mobilization of the<br />
cheek flap is<br />
accomplished by<br />
wide undermining.<br />
26
Mustarde Rotational Cheek Flap<br />
Good for very large defects<br />
Advantage – single stage procedure<br />
Preferable for patients with:<br />
– Monocular vision<br />
– Children with amblyopia<br />
– Active corneal disease<br />
– Glaucoma<br />
Disadvantages – lacks orbicularis,<br />
sagging<br />
Mustarde Technique<br />
27
Mustarde Technique<br />
• The size of the mucosal defect is estimated<br />
• Septal cartilage-mucosal composite graft to<br />
lend support to the newly reconstructed lateral<br />
canthal area<br />
• The cartilage thinned by splitting it (allows<br />
slight convex curvature of the cartilage )<br />
28
• Over correction in the vertical dimension<br />
allows good support<br />
• Anchoring of the cheek flap must be at the<br />
deep lateral canthal area with a permanent<br />
suture<br />

Upper <strong>Eyelid</strong> <strong>Reconstruction</strong><br />
• If a skin defect is present, direct closure,<br />
local flap, or skin graft may be indicated<br />
• Loss of the orbicularis muscle: should be<br />
replaced by moving adjacent muscle or by a<br />
composite muscle & skin graft from the opposite<br />
upper lid<br />
36
• An excellent flap for local coverage may come<br />
from adjacent lateral eyelid or temporal skin<br />
• Midline forehead & glabellar areas:color &<br />
texture match are not good<br />
• The best donor source for color & texture<br />
match: same/opposite upper lid skin<br />
• If there is significant loss of muscle, an adjacent<br />
reinnervated muscle flap/graft can be utilized<br />
• Full-thickness defects of the upper lid can be<br />
treated in the same way as the lower lid defects<br />

CORRECTION OF PTOSIS<br />
• Ptosis is defined as an abnormal drooping of<br />
the eyelid<br />
• The normal level of the eyelid is that position<br />
where it covers 1 - 2 mm of the upper limbus<br />
of the cornea<br />
48
CORRECTION OF PTOSIS<br />
• When dealing with ptosis patients, factors<br />
other than lid level must be considered,<br />
including the amount of levator function, the<br />
level of the ptotic lid, and the level of the<br />
opposite lid<br />
CORRECTION OF PTOSIS<br />
• The levator is skeletal muscle under<br />
voluntary control<br />
• Muller’s muscle is smooth muscle innervated<br />
by the sympathetic part of the autonomic<br />
nervous system<br />
49
CLASSIFICATION OF PTOSIS<br />
Congenital ptosis<br />
1. Simple<br />
2. With lid anomalies<br />
3. With ophthalmoplegias<br />
4. Synkinetic (Marcus-Gunn)<br />
Acquired ptosis<br />
1. Neurogenic<br />
2. Myogenic<br />
3. Traumatic<br />
4. Mechanical<br />
5. Pseudoptosis<br />
• Congenital ptosis is associated with myogenic<br />
dystrophic changes of the levator muscle<br />
resulting in poor levator function<br />
• A small percentage of these changes include<br />
two types: misdirected third cranial nerve<br />
(CN III) ptosis of the Marcus-Gunn type &<br />
blepharophimosis<br />
50
• Neurogenic ptosis includes CN III palsy,<br />
congenital or acquired, and Horner’s cervical<br />
sympathetic nerve palsy<br />
• Myogenic ptosis includes ―involutional‖ or<br />
senile ptosis; acquired muscular dystrophy;<br />
progressive external ophthalmoplegia; and<br />
myasthenia gravis<br />
• Traumatic ptosis varies according to the<br />
location of the injury to the levator muscle or<br />
lid mechanism<br />
• Mechanical ptosis is due to a tumor, cyst, or<br />
enlarged lacrimal gland pushing down the eyelid<br />
• Pseudoptosis refers to the drooping lid skin of<br />
blepharochalasis and to the apparent ptosis seen<br />
in the postenucleation eyelid<br />
• Before proceeding with surgery in the ptosis<br />
patient, it is wise to make a detailed evaluation of<br />
the history and development of the problem<br />
51
Useful guide to the workup of ptosis<br />
1. Obtain the patient’s history<br />
2. Perform a careful gross eyes examination<br />
3. Measure the supratarsal fold and symmetry<br />
4. Evaluate the lid contour<br />
5. Measure the ptosis (in millimeters)<br />
6. Measure the difference between the two<br />
eyelids (width of the palpebral fissure)<br />
Useful guide to the workup of ptosis<br />
7. Measure levator function<br />
(lid excursion with the brow static)<br />
8. Check the visual acuity of each eye<br />
9. Check the extra-ocular muscle movements<br />
10. Check for Bell’s phenomenon<br />
11. Check for jaw-winking motion<br />
12. Check for lagophthalmos and lid lag<br />
52
• Previous problems:excessive tearing or dryness,<br />
allergy, or irritation<br />
• Photographs<br />
• Tensilon test<br />
• Horner’s syndrome can be tested by stimulation<br />
with 10% phenylephrine hydrochloride solution,<br />
which corrects the ptosis<br />
Classification of Ptosis Severity:<br />
Mild 1–2 mm<br />
Moderate 3 mm<br />
Severe 4+ mm<br />
Classification of Levator Function<br />
Excellent 12–15 mm<br />
Good 8–12 mm<br />
Fair 5–7 mm<br />
Poor 2–4 mm<br />
53
Margin reflex distance<br />
– Number of millimeters<br />
from the corneal light<br />
reflex to the lid margin<br />
– Upper lid – 4 to 5 mm<br />
(rests slightly below<br />
limbus)<br />
– Lower lid – 5 mm (rests at<br />
the lower limbus(<br />
– Reflex to limbus – 2.5 mm<br />
Absent function of the levator<br />
• For patients with absent function and severe ptosis, a<br />
frontalis sling is the procedure of choice<br />
Fascia sling<br />
A:<br />
Incisions at the lid margin<br />
54
B: Fascia is inserted between the orbicularis<br />
muscle and the tarsus at the lid margin<br />
C: pulling fascia to the upper brow level<br />
55
D,E: Crossover of the fascia<br />
sling pulls the lid to the<br />
desired level. Simple suture<br />
ties are used for fixation<br />
F: <strong>Eyelid</strong> is at the desired level<br />
• The principle of this operation is direct<br />
attachment of the frontalis muscle at the<br />
brow to the lid margin by means of a fascia<br />
lata sling or strip<br />
56
Mild/Moderate ptosis with fair to good<br />
levator function:<br />
• To correct mild ptosis, separate or combined<br />
resection of the tarsal plate, Muller’s muscleconjunctiva,<br />
aponeurosis, levator muscle or<br />
Aponeurosis plication has been used effectively<br />
Mild/Moderate ptosis with fair to good<br />
levator function:<br />
• To correct moderate ptosis some form of<br />
levator shortening threw aponeurosis approach<br />
procedure is used by most surgeons<br />
• Levator resection, levator “tucking”<br />
procedures, levator advancement, and<br />
aponeurosis shortening procedures are the<br />
treatment of moderate ptosis<br />
57
Fasanella-Servat procedure: posterior conjunctival<br />
approach (Combination of tarsal plate resection with<br />
mullerectomy & aponeurosectomy)<br />
A: Ptotic eyelid<br />
B: Eversion of the lid, clamping the<br />
combined edge of the upper tarsus,<br />
conjunctiva, and Muller’s muscle<br />
C: Running crossover<br />
pull-out suture<br />
above the clamped<br />
area<br />
D: Excision of tissue included in the clamped specimen<br />
E: Tissue is excised, and the lid is shortened by excision<br />
of the tarsus, conjunctiva, and Muller’s muscle, with<br />
tying of crossover stitches.<br />
F: Final position of eyelid<br />

Aponeurosectomy (Anterior view)<br />
A: Exposure of the aponeurosis<br />
B: Excision of the<br />
ellipse of the<br />
aponeurosis, Muller’s<br />
muscle, and<br />
conjunctiva<br />
C, D: Closure defect<br />
E: Defect closed<br />
59
Aponeurosectomy (Lateral view)<br />
A: Exposure of the<br />
aponeurosis<br />
B: Excision of the<br />
ellipse of the<br />
aponeurosis,<br />
Muller’s muscle,<br />
and conjunctiva<br />
C, D: Closure defect<br />
E: Defect closed<br />
Aponeurosis plication<br />
A: Incision to expose aponeurosis<br />
B: Exposed<br />
aponeurosis with<br />
plication sutures<br />
C: Plication sutures<br />
tied to desired<br />
level<br />
D: Lateral view of<br />
plicated<br />
aponeurosis<br />
60
• The usual amount of plication is approximately 3<br />
mm to each 1 mm of ptosis<br />
• This procedure is not effective for patients who have<br />
progressive aponeurosis dehiscence (the aponeurosis<br />
will continue to dehisce)<br />
• The plication technique is an excellent noninvasive way<br />
to repair minimal long-standing eyelid asymmetry<br />
Levator advancement procedure<br />
moderate ptosis, fair to good levator function<br />
A: Incision in tarsal crease<br />
B: Exposure of<br />
aponeurosis and<br />
Whitnall’s ligament<br />
C, D: Isolation of<br />
levator muscle<br />
after Whitnall’s<br />
ligament has been<br />
dissected away<br />
E: Marking points on<br />
levator muscle &<br />
tarsus<br />
61
F: Cross-clamping of levator muscle at level of insertion<br />
into aponeurosis<br />
G: Advancement of levator muscle to tarsal plate, with<br />
fixation by permanent sutures<br />
H, I: Desired lid<br />
level achieved by<br />
advancement of 4<br />
mm of levator<br />
muscle to the<br />
tarsus for each 1<br />
mm of ptosis<br />
• It is usually best in a unilateral ptosis to have the lid<br />
level approximately 1.0 - 1.5 mm higher than the<br />
contralateral eye<br />
• Most surgeons prefer to use levator shortening as the<br />
first procedure, hoping to get a reasonably good<br />
result without having to resort to a fascia sling<br />
• If correction utilizing the patient’s levator muscle<br />
function is possible, it can potentially give a more<br />
natural result<br />

of technique and cases‖<br />

COMPLICATIONS<br />
• The best results are obtained in those patients who have<br />
the least severe ptosis with the greatest amount of<br />
levator muscle function<br />
• Selection of the proper operation for the patient is<br />
the most important part of the process<br />
• Under correction: the most common complication<br />
63
• Over correction: often leads to corneal exposure<br />
(especially during sleep), drying, and possible corneal<br />
erosion<br />
• If the over correction is mild, massage of the lid with<br />
gentle intermittent traction may be effective<br />
• If the procedure performed was tarsectomy or a similar<br />
operation, gentle separation of the suture line under topical<br />
anesthesia often corrects the problem by forcing the lid<br />
level down<br />
• If the over correction is severe, opening the defect in the<br />
aponeurosis and placing a scleral graft as a spacer may be<br />
necessary<br />
• This technique may allow the lid level to drop down to<br />
normal and overcome the corneal problems<br />
• Lagophthalmos: may result from removing a large amount<br />
of aponeurosis with subsequent adhesions preventing the<br />
downward motion of the eyelid<br />
• Usually time and massage take care of this problem, but in<br />
the interim the cornea must be protected from drying,<br />
especially at night, by artificial tears or ointment<br />
• If lagophthalmos persists and the lid level is normal,<br />
surgical exploration and lysis of adhesions may be<br />
indicated if severity of symptoms indicates it<br />
• Hematoma, excessive swelling: may occur and may<br />
compromise the result by causing excessive fibrosis,<br />
chronic edema, loss of lid fold, or loss of the surgical<br />
correction<br />
64
• Loss of eyelashes: may occur, probably due to<br />
dissecting too close to the lid margin during exposure of<br />
the tarsal plate<br />
• Once the loss occurs, there is no good procedure to<br />
correct it<br />
• Entropion: sometimes occurs as a result of removing<br />
too much tarsal plate or poor placement of the<br />
sutures, which reattach the levator muscle to it<br />
In summary: great care must be exerted to<br />
avoid the complications of ptosis surgery, as<br />
these problems may give rise to severe corneal<br />
symptoms or an unhappy patient. Moreover, they<br />
often require another operative procedure for<br />
correction<br />
65
Entropion<br />
Congenital<br />
– Hypertrophy of pretarsal orbicularis<br />
