Salasche CH2: Junctional and Cosmetic Units Flashcards
anatomic junction contour or boundary lines are fixed landmarks , such as the hairline, eyebrow or the nasolabial fold
T
aesthetic units are areas within boundary lines that share common characteristics
T
what are some surgical principles regarding cosmetic units
a) place scars within a junction or boundary line
b) repair within a cosmetic unit
c) borrow tissue from adjacent units and hide the donor scar in the junction line
d) replace the entire aesthetic unit if a significant portion is missing
which common characteristics do aesthetic units have in common
sebaceous quality hairiness pore size colour texture
contour lines are familiar to everyone and include universally present, fixed, strong landmarks of:
hairline eyebrows alar crease nasolabial fold philtrum vermillion cutaneous junction labiomental crease
junction line between forehead and scalp in a balding man can be determined by the most superior transverse forehead crease
T
eyelids are composed of one subunit
F, several subunits corresponding to various components of the orbiculares oris muscle
nose is most complicated aesthetic structures of the face
T
soft triangle is rigid and well supported
F, fragile and unsupported
1-2mm displacement of philtrum is not too disfiguring
F, readily noticeable and disfiguring
vermilion of lip extends from the white roll of the cutaneous - vermillion junction to the mucous membrane junction that corresponds to the line where the upper and lower lip join when the mouth is closed
T
chin is a very mobile unit
F, relatively immobile
cheek is dominated in the lateral view
F, frontal view by the convex molar region of youth and the lower jowl area in the aged
if there is insufficient tissue for closure within the unit, the next best choice is a skin graft
F - borrow from adjacent unit that is oftenclosely matched in quality
