Q

Latissimus dorsi

A

Vascular: Thoracodorsal vessels off of subscapular vessels
Nerve: thoracodorsal nerve
Noteworthy: Can be pedicled or free. Can be combined with serratus anterior for very large defects or two paddles. Not to be used for people who depend heavily on shoulder use. Positioning is a huge pain

Q

Fibula

A

Vascular: peroneal artery and vein; perforators run in posterior intermuscular
septum
Nerve: peroneal communicating branch
Bone: up to 25 cm of bone available, contourable due to segmental blood supply

Q

Iliac crest

A

Artery: deep circumfl ex iliac artery off of external iliac artery; internal oblique supplied
by ascending branch of DCIA
Venous: deep circumfl ex iliac vein usually composed of two venae comitantes
Natural shape conforms to that of native mandible

Q

Scapula

A

Artery: circumfl ex scapular artery off of subscapular artery, divides into transverse and
descending branches to supply two separate skin paddles (scapular and
parascapular)
Bone: separate thoracodorsal blood supply to bony component, 10–12 cm length from
inferior lateral aspect of bone

Q

Pectoralis

A

thoracoacromial artery, lateral thoracic (supplies inferior one-fi fth), IMA
perforators
° Donor site location easily accessible
° Donor site and pedicle generally outside of radiation fi eld
° Ease of harvest
° Pedicle not skeletonized
° Large density of arterial perforators
° Disadvantages: functional defi cit at donor site, limited reach to lateral canthus, disfi guration
in women, bulky fl ap

Q

Paramedian

A

Supratrochlear artery and vein

17
Q

Trapezius

A

occipital, suprascapular, transverse cervical arteries
° Can provide thin tissue suitable for pharyngeal defects
° Can be used as salvage fl ap for carotid coverage
° Little donor morbidity
° Disadvantages: vascular anatomy is variable, longer operating room time, special patient
positioning needed

18
Q

Temporoparietal

A

uperfi cial temporal artery and vein
° Thin and pliable
° Multiple applications in scalp, skull base, and midfacial reconstruction
° May be harvested for free tissue transfer
° Disadvantages: Harvest may result in alopecia at donor site.

19
Q

SCM

A

occipital artery, superior thyroid artery, branch from the thyrocervical
trunk
° Used for closure of defects in mouth, oro-, pharyngo-, and tracheocutaneous fi stulae and
at parotid bed.
° Restricted arc of rotation limits application of fl ap
° Carotid coverage may be lost if SCM is used

20
Q

Platysma

A

occipital, postauricular, facial, superior thyroid, transverse cervical arteries
° Limited role in head and neck reconstruction

21
Q

Nape of neck

A

Occipital

22
Q

Supraclavicular island flap

A

Artery: Transverse cervical->supraclavicular
