Q

Describe the continuity at the tissue plane of the deep temporal fascia

A

Cranial periosteum
Deep temporal fascia
Parotid masseteric fascia
Deep cervical fascia
The deep temporal fascia splits into two layers that surround the superficial temporal fat pad as they extend inferiorly
The superficial layer then becomes the parotid masseteric fascia

25
What is responsible for Marinette lines?
Osteo cutaneous ligaments include the zygomatic and mandibular ligaments Zygomatic ligaments are responsible for male, fat, descent, and nasolabial full deepening Volume deflation in the setting of an intact, mandibular ligament can lead to the presence of Marinette lines
26
Minimal access cranial suspension
The SMAS is purse string sutured to the DTF with two sutures to correct the neck and the lower third of the face and sometimes an additional suture to address the mailer fat pad
27
What is the risk of facial nerve injury in a primary versus secondary facelift?
Risk of nerve injury is the same
28
Describe the course of the spinal accessory nerve
Exit the jugular foramen Travels deep to the styloid process Courses underneath the SCM Exits from the posterior border of the SCM fascia within 2 cm superior to the GAN Susceptible to injury after it exits the muscle in the posterior triangle of the neck
29
Posterior triangle of the neck
SCM anterior border Trapezius posterior border Middle one third clavicle inferior Contain spinal accessory nerve The trunks of the brachial plexus Scapular and transverse cervical branches of the thyrocervical trunk External jugular vein
30
Anterior triangle of the neck
Posterior border is the SCM Anterior border is midline of the neck Superior border is the mandible Contains the vagus nerve Hypoglossal nerve Part of sympathetic trunk Mylohyoid nerve Anterior jugular veins internal jugular, common facial lingual, superior, thyroid, middle thyroid veins facial vein, submental vein
31
When is the ear It’s adult size.
80% of the adult size by age 6 90% above age 10 Ear width is reached by seven for boys and six for girls Length reaches by 13 for boys and 12 for girls Average width is 3 to 4 centimeters Height is 5.5 to 7 cm
32
Describe ear anatomy
Lies one ear length posterior and lateral from the lateral orbital rim Highest point of the ear coincides with the brow and the lowest point with the columella Angles approximately 15° posteriorly Upper third protrude 10 to 12 mm from the scalp Middle is 16 to 18 mm from the scalp Lower is 20 to 22 mm from the scalp
33
Furnas sutures
Placed in the concha and mastoid These are the last sutures placed after completion of all other steps The conchal angle is ideally less than 90°
34
Most common complication of otoplasty
Residual deformity
35
Where can the nose be injected with fillers?
The sub, SMAS plane above the plane of the periosteum in the nasal dorsum and side walls
36
What is a tension nose
Combination of thin, constricted, nasal skin envelope with strong, lower lateral cartilage, leading to a potentially twisted or deviated appearance Also defined as excessive growth of the quadrangular cartilage, resulting in a high dorsum and displaced lower lateral cartilages

Grenz zone
Sub epidermal region of dermis where neo collagen formation by fibrous occurs after wounding or damage This is the area that is responsible for the regenerative changes in the skin after treatments
48
49
What is the most predictable peeling agent?

Most common long, lasting side effect of phenol peels
Hypo pigmentation, which can be permanent
53
How do you increase the penetration of a laser?
Increase the pulse energy or increase the number of passes
54
Most common type of laser used for hair removal
Nd YAG
55
Another name for phenol
Carbolic acid
56
What is the long-term effect of Retin-A treatment of sun damaged skin?
Pre-malignant lesions regress
57
Mechanism of action of retinoids
Decreased activation of Metalloproteinases through inhibition of AP one transcription
58
What bio material is designed to be replaced by bone
Bioactive glass is both Osteo conductive and Osteo inductive
59
At what age is skeletal growth essentially complete
Cranial vault is complete at three years Facial skeleton is complete at 14
60
What kind of material should you use in a loadbearing cranial facial reconstruction?
Autologous

Coherent Monochromatic Intense
62
585 nm pulse died laser is absorbed by what chromophores
Oxyhemoglobin
63
