Principles techniques of wound closure
(reconstructive ladder)
What is ……
Flap:
In its basic form is a tongue of tissue
consisting of the entire thickness of skin
and variable amount of subcutaneous
tissue, which is transferred from one site
to another.
(McGregor)
Local / Regional flaps – Goals
(Kinnerw & Jeter)
1. Adequate color match
2. Adequate thickness – avoid protrusions or
deficiencies
3. Preservation of clinically perceivable
sensory innervation
4. Sufficient laxity – avoid retraction or
deranged function
5. Resultant suture lines of either primary or
secondary defects are restricted to
anatomic units and fall within natural skin
lines.
Delay of Flap: surgical outlining - before
actual transfer -improve circulation.
(1- 2 weeks)
2 basic schools
1. Delay improves nutrient blood flow
2. Delay increases the tolerance of the
cells to ischemia, allowing them to
survive at a lower flow rate.
Planning in Reverse : used when a local flaps
jumps over skin and in distant flaps.
1. Based on movement
Local flaps:
Advancement (single / bipedicle, V-Y)
Pivotal : Rotation
Transposition
Interpolation
Distant flaps
Direct
Tube
Microvascular (free)
Local Flap:
Regional Flap:
Musculocutaneous arteries
random arteries
myocutaneous
Septocutaneous arteries
fasciocutaneous
arterial
Septocutaneous arteries
Musculocutaneous system: Vascular system penetrating the
underlying muscles and then continues to supply the skin.
Skin (cutaneous)
Visceral ( colon, omentum)
Muscle
Mucosal
Composite
Fasciocutaneous
Myocutaneous
Osseocutaneous
Tendocutaneous
Sensory/innervated flaps
Osseo-myo-cutaneous
Based on vascular pedicle types
In muscles
used:
forehead, mustache area
and posterior neck.
A to T flap:
Useful for
defects at the periphery of the face
around the nasal ala and upper lip
Disadvantages:
number of scars- created with the three limbs and Burow’s triangle
and with the three point closure
V-y advancement flap: (Herbert flap)
The flap is then advanced so that the donor site closes primarily.
Derives its name from the pivot point at the base of the flap
as well as its arc of rotation .
Place the arc closest to the defect higher than the defect itself,
to reach the most distal point of the defect
sites of choice
retroauricular area
submandibular area A
perioral area for upper and
lower lip reconstructions.
scalp B
not to rotate more than 90º
BD=DE=EF
EF at angle of 60º &
Parallel to one side
Disadvantages:
Excess tension
Best in temple region between the eyebrows and anterior hair line
Limberg’s flap
Dufourmental flap:
Adv:
less closure tension
Disadv:
rotation puckering at point C
Double ‘Z’ rhomboid flap: by Cuono
reconstruct nasal and facial defects and even full thickness cheek
defects.
90º is the optimal angle between the first and second flap
Disadvantages:
Rotation pucker
S’‘ plasty: Schrudder
First by Szymanowski
½ or ¾ the defect
width
Interpolation flaps:
Types:
Advantages:
Easy
Donor site complications rare
Disadvantages:
Facial asymmetry is a possible complication
Buccal Pad Fat
Buccal pad of fat
Tongue flaps
First by Gersuny
Eiselberg popularized in 1901
advantages:
reliance on an excellent blood supply
low morbidity
Used to cover defects in cheek, floor of the mouth, soft palate and
hard palate, alveolus, oroantral fistulas and vermillion
and lip reconstruction
Classification of tongue flaps:
Uses:
anterior cheek,
lip,
anterior floor of the mouth,
anterolateral floor of the mouth and
palate
Transverse based dorsal tongue flap
unipedicled or bipedicled
Sushruta in 600 BC
popularized by Esser and Ganzer
Defect in the anterior face, nose and upper lip, floor of the mouth
OAF
Adv:
It provides thin, local tissue for coverage of small defects.
It may be also be deepitheliazed at the base
for one stage procedure.
Disadv:
Limited donor tissue
Facial scarring
Second surgical procedure might me needed
Difficult to use in the floor of the mouth if
the patient is not edentulous
Transfer of beard in male patients
Inferiorly based Superiorly based
Blood supply
superficial temporal artery and posterior auricular artery.
Disadvantages:
uses:
-nasal reconstruction
-cheek defects
disadvantages:
-donor site morbidity
-limited amount of tissue
Temporalis flap:
Golovine in 1898
Type III
Temporalis muscle - anterior and posterior deep temporal br. Max. art
Uses:
Useful for obliterating skull base,
maxillofacial and orbital defects.
It is also used in cranialisation procedure
Reanimation of the face
Used to close CSF leaks & dural tears
secondary to trauma & cancer surgeries.
Used for midface augmentation for
hypoplasia secondary to trauma &
congenital anomalies.
Advantages:
Close to the oral cavity
Good arc of rotation
Reliable and well tolerated
Thin flap
Problems from the loss of muscle function
are minimal
Disadvantages:
Cosmetic deformity in donor site
Traction paresis of Facial nerve
Temporalis flap
Narayanan bilobed flap
Uses:
Useful for obliterating skull base, maxillofacial and orbital defects.
It is also used in cranialisation procedure
Reanimation of the face
Advantages:
Close to the oral cavity
Good arc of rotation
Reliable and well tolerated
Thin flap
Disadvantages:
Cosmetic deformity in donor site
Facial nerve paresis
Cervicofacial flap:
•based laterally
•useful, well tolerated flap for closing cheek defects with or without
an associated neck dissection.
