a high-risk area due to the small caliber of the supratrochlear vessels.

A

38
Q

Measurement to decrease the incidance of intrascaular injection

A

aspiration prior to injection of the filler material, serial puncture
technique use, antegrade or retrograde linear threading technique

of filler superficial to arterial structures, and manual occlusion of
larger vessels in the treatment zone prior to injection

46
Q

Can we use antibiotic use after a filler procedure?

A

Recently, biofilm-producing bacteria have been implicated in the development of delayed-presentation nodules after the use of dermal fillers leading to consideration of antibiotic use after a filler procedure.

49
Q

Toxin canot moves to distant palce

A

F. Migration of the toxin, defined as its movement to distant tissues, can occur either by neuroaxonal transport or hematogenously

50
Q

centrally acting effect of the toxin has been recorded

A

T

51
Q

Why the incobotulinumtoxin A is safer than other forms of botox

A

incobotulinumtoxinA contains only the active 150 kDa neurotoxin responsible for the therapeutic effect

52
Q

Before using botox for. Upper Extremity Vasospastic Disorders the patient should undergo vascular imaging studies to rule out occlusive disease.

A

T

53
Q

Onlabel indication of Botox

A

botulinum toxin uses are glabellar lines and lateral canthal lines (crow’s feet)

54
Q

Off label use of botox

A

off-label uses include forehead lines, lateral nasal lines,
perioral rhytids, marionette lines, and platysmal bands

55
Q

Which drug potentiate the botox effect

A

Aminoglycosides, penicillamine, quinine, and calcium
channels may potentiate the effects of botulinum toxin;
whereas choloroquine and hydroxychloroquine may
reduce the effects

56
Q

Absolute contraindications

A

known hypersensitivity
reactions to any ingredient in the formulation, including
lactose (Dysport) and albumin (all preparations), as well as
preexisting infections at the injection sites

Q

Risk of ptosis after glabelar injection

A

eyelid ptosis (about 3%)

69
Q

The injection sites for this area start in the lateral orbicularis oculi muscle, just temporal to the lateral orbital rim. The other
areas are 1 cm superior and 1 cm inferior with a 30-degree angle
toward the midline.

A

T

70
Q

injections should not extend inferior to the maxillary prominence.

A

T

71
Q

The most frequent adverse reactions following injection of botulinum toxin in the lateral canthal region are eyelid edema and bruising
(about 1%)

A

T

72
Q

The lower treatment
row will be halfway between the superior extent of the frontalis muscle and the eyebrow

A

T

73
Q

The upper treatment row will typically be halfway between the superior aspect of the frontalis muscle and the lower
treatment row

A

T

74

The most frequent adverse reactions following injection
of botulinum toxin for forehead lines are headache (9%), brow ptosis
(2%), and eyelid ptosis (2%)

A

T

75
Q

the standard plane of injection
is intramuscular, subcutaneous injections may be equally effective in
achieving paralysis

A

T

76
Q

When the central and lateral portions ofthe frontalis are
weakened, there is compensatory contraction of the frontalis muscle directly over the brow resulting in elevation

A

T

78
Q

Hyperactive platysmal bands in the superficial subdermal space can
be visualized and are the target of treatment

A

T

79
Q

It is well accepted that patients
with excess skin laxity in the neck are not good candidates for this
procedure as they have minimal overall improvement

A

T

80
Q

How many maneuvers has been used in neck botox injection

A

patients were injected with botulinum toxin along the inferior
border of the mandible and with the platysmal bands using a mean
dose of 124.9 units (however, some express concern given the high dose needed for effect and the potential risks of dysphagia and salivary gland dysfunction)

Direct platysmal band injection with 20 units of botulinum toxin.

Q

Botox is currently indicated for the treatment of chronic
migraines, defined as at least 15 days per month with headaches that

Prior to injection, patients
should undergo vascular imaging studies to rule out occlusive disease. in RF

A

T

84
Q

50-100 units of Botox
was injected into the palm directed toward the neurovascular bundles of the digits

A

T

85
Q

absolute contraindications for BoNTs are only two: hypersens1t1V1ty to any BoNT preparation (including any component of the
preparation) and infection at the injection site

A

T

86
Q

For Botox,
this includes 20 units for glabellar lines, 24 units for lateral canthal
lines, 40 units for forehead lines, 44 units for simultaneous lateral
canthal and glabellar lines, and 64 units

A

T

87
Q

Migraine doses

A

The recommended dosage is 155 units administered intramuscularly, divided between seven sites in the head and
neck: corrugators (5 U each side), procerus (5 U), frontalis (5 U each
side), temporalis (5 U each side), occipitalis (15 U each side), cervical
paraspinal muscles (10 U each side), and trapezius (15 U each side)
