Type 3 (10%) shows no decussation.

Minor hematoma is defined as a collection of blood that does not require surgical evacuation but is amenable to treatment by bedside aspiration,
with volumes under 30 cc

A

T

67
Q

Minor hematomas consequences

A

unpleasant aesthetic results

68
Q

expanding hematoma is a serious
complication with an incidence of 1.8% that requires immediate
recognition and treatment due to impending risk of skin necrosis,
airway obstruction, and death.

A

T

69
Q

Measurement to decrease the incidence of hematoma

A

Strict blood pressure control in the operating room (SBP < 150 mm Hg) is a widely recognized preventive
intervention(Antihypertensive clonidine has been used successfully
in the postoperative period to keep SBP under 140 mm Hg)
The use of fibrin glue,
absence of epinephrine in the local anesthetic solutions,
and compressive dressings have been reported to be beneficial but are
not completely effective in preventing hematomas.
use of quilting sutures is a promising strategy in prevention of hematoma in the face by reducing the rate of hematoma to zero in the published series

Q

the SMAS as a superficial
fascia investing the face and the superficial mimetic muscles. It is contiguous with the galea aponeurotica, the temporoparietal fascia, parotid
masseteric fascia, platysma muscle, and superficial cervical fascia

A

t

82
Q

The fixed SMAS is firm and
lateral over the parotid gland. The mobile SMAS is softer and medial,
over to the zygomatic and masseteric retaining ligaments toward the
central face

A

t

83
Q

The most superficial layer ofmuscles is intimately related to the
medial extension ofthe SMAS. Traction and suspension ofthe SMAS
will also suspend the muscles

A

T

84

The great auricular nerve is a nerve of the cervical plexus
(C2, C3) that provides the dominant sensory innervation to the ear
(lobule, concha, and posterior auricle)

A

T

85
Q

The transverse facial artery branches off the superficial
temporal artery at the level of the external auditory meatus and travels anteriorly supplying the lateral face and lateral orbital area

A

T

86
Q

Aesthetic analysis is done by dividing the face into horizontal thirds and vertical fifths

A

T

87
Q

The frontal branch is vulnerable to injury as it crosses
the zygomatic arch 2.5 cm anterior to the external auditory meatus deep into
the temporoparietal fascia

A

T

88
Q

The SMAS can be elevated as a flap (high SMAS technique), can be
resected (SMASectomy), or can be plicated with or without tissue
stacking

A

T

89
Q

In the high SMAS technique, the SMAS flap is elevated at or
above the zygomatic arch with medial dissection with at least partial
transection of the zygomatic and masseteric-cutaneous ligaments for
full mobilization of the cheek and jaw line

A

T

90
Q

The subcutaneous undermining accompanies the SMAS undermining and extends
anteriorly to include the area of the mandibular ligaments and the
neck

A

T

91
Q

The lateral SMASectomy technique was popularized by Baker

A

includes resection of a diagonal strip of SMAS from the malar eminence to the angle of the mandible, parallel to the nasolabial fold with
posterior SMAS plication. The edges of the fix and mobile SMAS are
brought together with sutures for elevation of the jowls and cheek

92
Q

In the SMAS plication technique, there is no flap elevation or
resection of SMAS. The edges of the fixed and mobile SMAS are
simply plicated together with sutures

A

T

93
Q

In the minimal access cranial suspension lift (MACS lift) developed by Tonnard, large purse-string suture loops are used to suspend the SMAS platysma in a cranial position instead of using the traditional individual plication sutures placed parallel to the nasolabial
fold

A

T

94
Q

The deep plane approach The skin flap dissection in front of the ear is limited and there
the transition into a skin-SMAS flap starts laterally, over the deep
parotid fascia

Q

differentiate between subcutaneous fat and deep fat during the clinical
exam

A

the submental fat is pinched and the patient is asked to grimace
to contract the platysma muscle. If the amount of fat does not change
with contraction, it indicates that most of the fat is subcutaneous and
liposuction is a good option for fat removal.

99

Small cannulas (size 2-3) are recommended to
prevent excessive resection of fat and surface irregularities.

A

T

100
Q

The platysma is a pair of superficial muscle of the neck that originates
from the pectoralis major muscle fascia and inserts into the mentum
and the inferior mandibular border

A

T

101
Q

Stuzin discussed the importance of the platysma retaining ligaments in the aging neck

A

These ligaments are a series of fibrous
bands connecting the mandibular symphysis to the thyroid and once
attenuated contribute to platysma descent, band formation, and the
oblique cervical angle of the aging neck

102
Q

Submental necklifting consists in treatment of the central neck
through a submental incision

A

T

103
Q

incision is placed just posterior to the submental crease

109
Q

In an anterior neck, the superficial and deep planes of the
neck can be resected.

A

T

110
Q

straight resections are avoided to prevent banding and scar contraction. Most incision patterns are variations of z-plasty in the midline

A

T

are some of the downsides of this approach.

A

115
Q

The “pixie ear” deformity is a known tell-tale sign of previous
facelift

A

T

116
Q
