The document discusses different types of flaps that can be used for head and neck reconstruction including local, regional, distant and free flaps. It also discusses principles of wound closure and goals and techniques for using local flaps.

The different types of flaps discussed include local, regional, distant, free, axial, random, advancement, pivotal, transposition, interpolation and musculocutaneous flaps.

Some of the goals of using local flaps discussed are adequate color match, thickness, preservation of sensory innervation, sufficient laxity and restricting suture lines to fall within natural skin lines.

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.

( a piece of fabric to represent it the flap is


taken in reverse through various stages of
the mock transfer to ensure that the real
flap is large enough and long enough to
reach its destination without kinking or
undue tension at any stage of transfer)
Classification of flaps

1. Based on movement
Local flaps:
Advancement (single / bipedicle, V-Y)
Pivotal : Rotation
Transposition
Interpolation
Distant flaps
Direct
Tube
Microvascular (free)
Local Flap:

skin flap taken from an area close to the wound.

E.g. a wound on the lip may be repaired by a


flap from the adjacent cheek.

Regional Flap:

skin flap is not from the adjacent area, but is


from the same region of the body.

E.g. a wound on the tip of nose might be repaired with


a flap from the forehead.
Distant Flap:

- When a flap is from a different part of


the body.
- Any flap taken from below the lower
border of the mandible is considered a
distant flap.
A local flap repair is usually
done in one operation, whereas
regional and distant flaps need two or
more operations.
Free Flap:

This is a distant flap, but the whole


procedure is done in one stage by
repairing the donor and recipient
blood vessels by microsurgery.
2. Based on blood supply:
Axial
Random

Daniel (1973) blood supply to skin:

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.

Random cutaneous: it is composed of skin and subcutaneous fat with


multiple musculocutaneous arteries at the base.

Myocutaneous flap: it is composed of skin, subcutaneous fat and


muscle with its blood supply coming from muscular arteries
plus numerous terminal musculocutaneous arteries.
Septocutaneous system: vascular system reaching the skin
through septa between muscles. (groin & DP flaps)
3. Based on composition

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

Mathes and Nahai (1979)

Type I: one vascular pedicle


Type II: dominant pedicle (s) + minor pedicles
Type III: two dominant pedicles
Type IV: Segmental vascular pedicles
Type V: dominant pedicle + secondary segmental pedicles
Areas of skin availability exploited most commonly
for facial local flap transfer

Palpation & PINCH Test


Advancement flaps
flap moves in a straight path without any lateral
movement into the primary defect.
(Burrows Triangle’s)
sites – forehead, brow, cheek.

Single advancement flap:


movement is entirely in one direction.
Bilateral advancement flap:

When large tissue is required.


Same technique & principle.

used:
forehead, mustache area
and posterior neck.
A to T flap:

variant of bilateral advancement flap

Useful for
defects at the periphery of the face
around the nasal ala and upper lip

dog–ear almost always forms

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)

A V shaped flap is moved into a defect with primary


closure of the donor area leaving a final Y shaped
suture line.
It is pedicled from the underlying subcutaneous
tissue rather than the surrounding skin.

Ideal for Lesion in


the cheek
and alar base
Burow’s triangular flap

Variation of advancement flap

cover those areas on the face where there are


anatomical structures on one side of the defect
that should not be pulled or stretched.

repair of upper lip or over the lateral eyebrow,

Point C moves to point B


&
point D moves to point F
Panthographic expansion:

variation of the advancement

instead of the flap being advanced as a rectangle,


the limbs of the flap are designed at 120º with back cuts at the
bottom so that it looks like an inverted tumbler.

The flap is then advanced so that the donor site closes primarily.

This technique is particularly useful on the cheek and neck.


Pivot flaps:

Derives its name from the pivot point at the base of the flap
as well as its arc of rotation .

When flap moves laterally into the primary defect - transposition


flap

when it is rotated into the defect - rotation flap

isosceles triangle- triangulation of the defect


Pivot point

Is the axis around which the transfer takes place.

Flap is designed so that the distance from the pivot


point to each part of the flap before transfer is
atleast equal to the distance to be expected after
transfer

pivot point is on the side of the flap away from


the direction of movement of the flap.
Rotation flaps: it is semicircular flap that rotates about a pivot point
to fill the defect.

Place the arc closest to the defect higher than the defect itself,
to reach the most distal point of the defect

Should be 5-8 times the width of the defect


Simple rotation flap

Ideally suited on a convex surface


cheek
Submandibular area
Bilateral rotation flap
Transposition flaps
Classic form - a rectangle or near square which is raised
and moved laterally into a triangular defect

In a correctly designed flap, the distance from the pivot point to A


equals the distance to B and the transfer is carried without tension

sites of choice
retroauricular area
submandibular area A
perioral area for upper and
lower lip reconstructions.
scalp B
not to rotate more than 90º

More acute –less dog ear


Transposition flap
Methods for correction of “dog ear”
Limberg’s flap:

combination of flap rotation and


transposition

BD=DE=EF
EF at angle of 60º &
Parallel to one side

Disadvantages:
Excess tension

Anatomic landmark displacement because the tissue used to resurface


the rhomboid defect is borrowed from single area.
Rotation pucker at Point C

Best in temple region between the eyebrows and anterior hair line
Limberg’s flap
Dufourmental flap:

variation of a rhomboid flap

Need not convert into 60º rhomboid

Such flaps are designed for closure of


square & rectangular defects.

Adv:
less closure tension

Disadv:
rotation puckering at point C
Double ‘Z’ rhomboid flap: by Cuono

Advantage over Limberg flap:

Excessive tension is reduced by using


two flaps

anatomic landmark displacement in


minimized because tissue used to
resurface the rhomboid defect is
borrowed from two areas.

Rotation pucker seen with Limberg flap is avoided and the


resultant scar forms an elongated ‘Z’ plasty.
First by Esser in 1918
Bilobed flap: popularized by Zimany

reconstruct nasal and facial defects and even full thickness cheek
defects.

Tension free closure of original and secondary defects.

90º is the optimal angle between the first and second flap

Maximum distortion occurs around


the flap bases and the second donor
lobe closure sites

Disadvantages:
Rotation pucker
S’‘ plasty: Schrudder

First by Szymanowski

modification of transposition flap

Difference between transposition and S- plasty

Proximity of the flap base to the defect.


It is positioned tangential to the wound margin
leaving a ‘V’ shaped flap between them.

Intermediate flap created between the flap and the defect.


60 degree between the flap and the
defect will avoid ‘dog ear’

1/5th to 1/6th higher

½ or ¾ the defect
width
Interpolation flaps:

An interpolation flap is from a nearby, but not immediately


adjacent donor Site and transposed either above or below
the intervening skin to the Recipient defect
