and Müller’s muscle<br />

<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 />

b- Fricke flap<br />

c- midline forehead or glabellar flap<br />

d- medial & lateral skin-muscle flaps<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 />

Ptosis – upper eyelid margin abnormally<br />

inferiorly displaced<br />

Entropion – inward rotation of eyelid margin<br />

Ectropion – eversion of eyelid margin<br />

Trichiasis – misdirected eyelashes<br />

47


Related Vocabulary<br />

Distichiasis – aberrant eyelashes from<br />

metaplastic meibomian glands<br />

Epiblepharon – normal eyelashes pushed<br />

toward the eye by redundant folds of skin<br />

Epicanthal folds – vertical folds of skin over<br />

the medial canthus<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

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 />

Levator aponeurosis plication<br />

blepharoplasty approach<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 />

– Deficiency or absence of tarsal plate<br />

– Dehiscence of eyelid retractors<br />

Involutional (senile)<br />

– Loss of orbital volume—enopthalmos<br />

– Upward migration of preseptal orbicularis<br />

– Laxity or dehiscence of eyelid retractors<br />

– Thinning of tarsal plate<br />

Epiblepharon<br />

– In-rolling of lid margin and<br />

lashes over superior tarsal edge<br />

– More common; bilateral<br />

– Lack of adhesion between lid<br />

retractors and anterior lamella<br />
