ANATOMY
1. A patient is asked to tightly close the eyes against resistance. Which muscle is mainly responsible for this
action?
E. Orbital orbicularis.
The orbicularis oculi muscle forms a sphincter responsible for eyelid closure. The orbicularis has three parts: pretarsal, preseptal, and orbital. The orbital orbicularis is under voluntary control and is activated during forceful closure of the eyelids and is innervated by frontal and zygomatic branches of the facial nerve. The preseptal orbicularis has both voluntary and involuntary functions and is involved in blinking. The pre­tarsal orbicularis is also involved in blinking and is involuntary.
The corrugator muscles draw the medial brow downward and medially. The procerus muscle lies primar-
ily over the upper third of the nose and its contraction results in transverse rhytids over the nasion.

2. The levator palpebrae superioris muscle originates from which of the following bones?
B. Lesser wing of the sphenoid.
The levator palpebrae superioris is innervated by cranial nerve III and originates from the lesser wing of the sphenoid in the bony orbit.

3. A patient presents to clinic 6 days after botulinum toxin A injection to the glabella complaining of left upper
lid ptosis. Which of the following best describes the mechanism of action of apraclonidine, which is used to help address this issue?
C. Stimulates Müller's muscle via alpha-2 adrenergic agonist effects.
Botulinum toxin A inhibits release of acetylcholine from the pre-synaptic terminal; therefore, answer choice A is incorrect as this describes the mechanism of action of botulinum toxin A. Apraclonidine is an alpha-2 adrenergic agonist and stimulates sympathetically innervated muscle. Müller's muscle is a sympathetically innervated involuntary muscle which contributes to 2 to 3 mm of upper eyelid excursion. Apraclonidine, therefore, stimulates Müller's muscle and can be used to ameliorate lid ptosis due to inadvertent botulinum toxin effect on the levator palpebrae superioris muscle. Local anesthetics (i.e., lidocaine) are categorized as class 1 antiarrhythmics and bind/block sodium channel receptors, preventing sodium ion f low and mem­brane depolarization. Therefore, answer choices D and E are incorrect.

4. Which of the following correctly describes the function of Whitnall's ligament?
A. It redirects the vector of pull of the levator palpebrae muscle on the superior tarsal plate.
Whitnall's ligament functions as a fulcrum, helping to redirect the vector of pull of the levator palpebrae superioris muscle on the superior tarsal plate. Whitnall's ligament also contributes fibers to the medial and lateral canthal tendons. The orbital septum, not W hitnall's ligament, forms the middle lamella of the eyelid and lies between the orbicularis muscle and orbital fat. In the inferior lid, Lockwood's ligament functions as a fulcrum to redirect the vector of pull of the capsulopalpebral fascia.

5. A 65-year-old female returns to clinic 2 months after upper blepharoplasty complaining of a tiredappear-
ance of her left upper lid. There is no evidence of lagophthalmos. Examination reveals 10 mm of levator excur­sion bilaterally, with an MRD-1 of 2 mm on the left and 4 mm on the right. Which of the following is the most likely reason for this patient's postoperative complaint?
B. Failure to recognize preoperative eyelid ptosis.
The vignette describes a patient with nor mal levator excursion (normal 10–15 mm) but left eyelid ptosis. Although iatrogenic disruption of levator aponeurosis attachment to the superior tarsal plate can result in ptosis, it is much more common for postoperative upper lid ptosis to be due to unrecognized preoperative eyelid ptosis. A browlift would have not addressed this patient's ptosis. Insufficient skin resection would result in persistent postoperative dermatochalasis. Over-resection of the skin causing lagophthalmos would have presented differently in a patient who has difficulty closing eyelids due to over-resection.

6. A 58-year-old female is 9 months post bilateral upper blepharoplasty and complains of right eye irritation and
dryness. Examination reveals 2 mm of right eye lagophthalmos and conjunctival injection without evidence of ulceration. Which of the following is the most appropriate management?
D. Full-thickness skin graft.
Lagophthalmos is a relatively common complication after upper blepharoplasty and can result from exces­sive resection of skin. If present in the acute postoperative period, conservative management is appropriate including hydrating ocular ointment application and downward scar massage on the upper eyelid, as many cases will resolve over time. However, this patient is 9 months status post upper blepharoplasty with per­sistent lagophthalmos. A full-thickness skin graft from the contralateral eyelid, cervical, preauricular, or pos­tauricular area is appropriate. A full-thickness skin graft will add additional tissue to the anterior lamella and is an effective treatment of persistent iatrogenic lagophthalmos. Excising more skin from the upper lid would cause worsening of her lagophthalmos.

7. A 61-year-old woman with significant herniation of upper eyelid orbital fat is to undergo bilateral upper
blepharoplasty with partial excision of orbital fat. The superior oblique muscle is most susceptible to injury between which of the following structures?
A. Medial and central fat compartments.
The trochlea of the superior oblique muscle separates the medial and central fat compartments of the upper orbit. Therefore, the superior oblique muscle is most susceptible to injury in this location and can result in strabismus (i.e., misalignment of the affected eye).

8. During blinking (i.e., eyelid closure), which of the following best describes the action of the lacrimal sac?
D. It expands due to contraction of the orbicularis oculi muscle.
The lacrimal apparatus is a complex drainage system. The tear film first drains into the punctum, which then drains into the lacrimal sac via the canaliculus. The lacrimal sac then drains into the nasolacrimal duct, which drains into the nasal cavity at the inferior turbinate. Jones's muscle (deep head of the preseptal orbicularis) inserts onto the lacrimal sac. During eyelid closure and orbicularis muscle contraction, Jones's muscle expands the lacrimal sac. Expansion of the lacrimal sac results in negative pressure, which draws the tear film into the lacrimal sac. During eyelid opening, the lacr imal sac recoils (i.e., relaxes) down to its resting size and projects the tear down the nasolacrimal duct.
The lacrimal sac does not contract independently. Expansion and recoil (i.e., relaxation) of the lacrimal gland is secondary to the action of the orbicularis oculi muscle. Furthermore, the lacrimal sac expands dur­ing eyelid closure. The lacrimal sac does not relaxin the same sense as muscles do. Instead, it participates in the ongoing drainage process as tears are produced and the eye blinks and moves. The lacrimal sac does change in size due a variety of factors previously mentioned.

PREOPERATIVE EVALUATION
9. Which of the following is an absolute contraindication to upper blepharoplasty?
A. Coumadin use for a prosthetic heart valve.
Retrobulbar hematoma is a rare, but severe, complication after blepharoplasty which can result in blindness due to compression of the optic nerve. Patients on therapeutic anticoagulation are not candidates for upper blepharoplasty due to an increased risk of bleeding.
It is recommended that blepharoplasty should not be performed earlier than 12 months after Lasik pro­cedure. The patient in the above vignette is 14 months after Lasik surgery and therefore blepharoplasty is not contraindicated. Hypothyroidism, contact lens use, and controlled hypertension are not contraindications to blepharoplasty.

PREOPERATIVE EVALUATION
10. A 72-year-old female presents to your office requesting a skin-only upper blepharoplasty complaining of
extra skinpartially occluding her visual fields bilaterally. Physical examination reveals deep transverse forehead rhytids and pronounced lateral hooding bilaterally. Levator excursion and MRD-1 are 11 and 5 mm bilaterally, respectively. You counsel the patient and recommend which of the following surgical interventions?
E. Browlift and upper blepharoplasty.
The clinical vignette describes a patient with concomitant brow ptosis. Deep transverse forehead rhytids are due to increased frontalis muscle tone. Unconscious frontalis muscle activation can occur to compen­sate for brow ptosis and/or blepharoptosis. However, the patient has 11 mm (normal) of levator excursion and an appropriate distance bet ween her corneal light reflex and upper lid margin (i.e., MRD-1 5 mm). Therefore, this patient is best served by first treating her brow ptosis and a concomitant upper blepharoplasty.
Isolated upper blepharoplasty is incorrect and would produce a suboptimal aesthetic result. In a patient
with concomitant brow ptosis, isolated blepharoplasty also risks excision of excess tissue.
There is no indication that this patient is not a surgical candidate.
Neurotoxin injection of the frontalis would exacerbate the patient's brow ptosis, and potentially result in
occlusion of her visual fields.

11. The nurse pages you to evaluate a 60-year-old patient who underwent bilateral upper blepharoplasty 2 hours
ago. On examination, the patient complains of severe pain, and proptosis of the left globe is noted along with decreased visual acuity. Which of the following is the correct next step in management?
E. Emergent lateral canthotomy and cantholysis.
The clinical vignette describes a patient with a retrobulbar hematoma. A retrobulbar hematoma can result from a bleeding vessel after orbital fat excision. Although emergent ophthalmology consultation and phar­macologic interventions are indicated, visual compromise is an indication for emergent decompression to prevent permanent blindness. Therefore, a bedside lateral canthotomy and cantholysis under local anesthe­sia is first indicated, followed by return to the operating room to obtain hemostasis along with ophthalmol­ogy consultation and pharmacotherapy.

ANATOMY
1. An outward turning of the eyelid margin defines which of the following terms?
C. Ectropion.
An ect ropion is defined as an outward turning of the eyelid margin and can be further classified as senile or cicatricial. Senile ectropion results from age-related laxity of the lower eyelid. Cicatricial ectropion results
from scar-induced retraction of the lower eyelid.
An entropion is a rolling in of the eyelid margin toward the sclera. This can result in irritation of the cornea or sclera by the individual's eyelashes. Retraction is a downward displacement of the lower eyelid resulting in inferior scleral show. Steatoblepharon is excess or protruding fat through a lax septum. Blepharochalasis is thin, excessive eyelid skin secondary to recurrent bouts of painless eyelid edema.

B. Resting position of the lower eyelid at the level of the limbus without scleral show, fullness of the pre-

The lower eyelid should rest at the level of the limbus without scleral show between the limbus and the eye­lid margin. The presence of a pretarsal bulge, or pretarsal orbicularis hypertrophy, is considered by many to be an aesthetic component of the youthful eye. The eyelid–cheek junction should be a smooth, convex, essentially imperceptible, transition from eyelid to cheek in youthful patients.

D. Ectropion.
The orbital vector or position of the globe relative to the inferior orbital rim is useful for predicting postop­erative tendencies of lid position. Negative vector orbits have poor lower lid suspension and are at risk for postoperative ectropion and retraction.

4. What is the definition of an abnormal pull-away test and what procedure is indicated to correct the
abnormality?
B. Greater than 10 mm of laxity of the lid margin when pulled away from the globe indicates that a sup-
plemental canthal anchoring procedure should be performed.
Both the pull-away test and snap-back test are ways to examine for horizontal lid laxity. The pull-away test is abnormal when there is greater than 10 mm of lid laxity when the examiner grabs the lid margin with his or her index finger and thumb and pulls it away from the globe. A snap-back test is abnormal when there is delayed return of the lid margin to native positive when retracted downward with finger traction. A squinch
246 Part VII&Facial Surgery
(or squint) test can tell you if festoons are caused by ptosis of the orbicularis oculi muscle. The festoon will improve with forced closure of the eyelids. If either the snap-back or pull-away test is abnormal then the patient would benefit from a supplemental canthal anchoring procedure if undergoing lower blepharoplasty.

5. A 52-year-old man has come to the plastic surgeon's office seeking improvement in the appearance of his
lower eyelids. He expresses concerns about the persistent bags under his eyes that make him look tired and aged. On examination he has a negative vector, skin elasticity, and poor snap-back test. What is the patient at risk for and what maneuver may help decrease the possibility of that complication from arising?
D. Ectropion–canthopexy.
Given the patient's description and examination findings, he is at risk for developing lower eyelid malpo­sition after undergoing lower blepharoplasty surgery. The combination of a negative vector (where the lower eyelid is positioned below the level of the eyeball), poor skin elasticity, and a positive snap-back test (indicating reduced elasticity and poor tissue recoil) can contribute to potential complications involving the position and contour of the lower eyelid post-surgery.
One possible complication that can arise due to these factors is ectropion. Ectropion is a condition in which the lower eye lid turns outward, exposing the inner surface of the eyelid and causing discomfort, irritation, and an unnatural appearance. Given the patient's existing risk factors, there is an increased chance that the lower eyelid might not heal properly and could become pulled downwar d or have an abnormal position.
To decrease the possibility of ectropion and ensure a successful outcome, the plastic surgeon may employ a surgical maneuver known as a canthopexy or canthoplasty. These procedures involve tightening and sta­bilizing the lateral canthal tendon, which is the tissue that holds the outer corner of the eyelid in place. By reinforcing this structure, the surgeon can help prevent lower eyelid malposition, mitigate the risk of ectropion, and ensure a more natural and comfortable appearance after the surgery.

Skin-only or pinch blepharoplasty is indicated in patients with minimal redundant skin or fullness, usually iso­lated to the pretarsal region, and not associated with fat herniation, lid laxity, or orbicularis ptosis. If pretarsal orbicularis hypertrophy is present and contributing to excessive fullness, a strip of pretarsal muscle may be excised as well. The pinch technique can be combined with other blepharoplasty technique s if indicated.

8. A patient presents with apparent skin excess of the lower eyelid and a ptotic orbicularis muscle. What is the
key surgical step to address the ptotic orbicularis muscle?
D. Suspension of a preseptal orbicularis oculi flap to lateral orbital rim.
External skin-only techniques do not adequately address orbicularis ptosis even if a strip of orbicularis oculi muscle is removed. Along with elevating a pennant flap of the preseptal orbicularis muscle, the surgeon must also release the orbital retaining ligament and lateral orbital thickening in order to adequately suspend the flap to the lateral orbital rim.

9. Which of the following is an indication to perform a septal reset procedure?
E. Visible nasojugal groove and fat herniation.
A visible nasojugal groove and fat herniation along with the presence of the tear trough triad (herniation of orbital fat, tight attachment of the orbicular along the arcus marginalis, and malar retrusion) are indications to perform a septal release to allow herniation of the postseptal fat over the inferior orbital rim, or septal reset. Septal reset procedures should be performed with the eyelid under tension (by temporary Frost suture) to prevent excessive tightening of the septum and predisposing patients to ectropion.

10. Which of the following must be considered when determining whether to perform a canthal anchoring pro-
cedure (canthopexy or canthoplasty)?
A. Amount of horizontal lid laxity present.
The decision to perform canthal anchoring is based upon the amount of horizontal lid laxity (preopera­tively determined by the snap-back testand pull-away test), the prominence of the globe (a negative vector globe is at considerably higher risk of developing ectropion), the amount of skin/muscle resection planned, and other ancillary procedures performed (facial rhytidectomy, laser facial resurfacing, chemical peel, etc.). Whether orbicularis oculi muscle incision leads to paralytic ectropion after blepharoplasty is controversial. Pretarsal innervation is maintained through medial branches if the incision is only through the lateral aspect of the muscle. When muscle-splitting techniques are performed it is important to per­form proper preoperative risk assessment and routine lateral canthal anchoring procedures for a successful outcome.

D. Prompt return to the operating room for exploration.
Retrobulbar hematoma is a rare but serious complication with an incidence of 0.04%. A retrobulbar hema­toma can compress the neurovascular structures and cause retinal ischemia and optic nerve compression. Symptoms include severe pain, visual changes, proptosis, and ecchymosis. Any indication of retrobulbar hematoma should result in prompt return to the operating room for reexploration. If there is any delay,
