Flaps and Grafts

“….the application of anatomical knowledge

to restore form and function…”

Graft VS FlapWhat is the difference?

What is a Flap?

• 16th century Dutch word “flappe”

– ….something that hangs broad and loose , fastened only by one side..”

What is a Flap?

• A flap is a unit of tissue that may be transferred from a donor to a recipient site while maintaining its blood supply.– Flaps can be characterized by their component parts

• cutaneous, musculocutaneous, osseocutaneous

– Their relationship to the defect• local, regional, or distant

– Nature of the blood supply• random versus axial

– The movement placed on the flap• advancement, pivot, transposition, free, pedicled

• Rung 1: Healing by secondary intention

• Rung 2: Primary closure

• Rung 3: Delayed primary closure

• Rung 4: Split thickness graft

• Rung 5: FTSG

• Rung 6: tissue expansion

• Rung 7: Random flap

• Rung 8: Axial flap

• Rung 9: Free Flap

Which flap when?

Goals of reconstruction

• Separating the physiological cavities – Eg brain, orbit, mouth, neck

• Protecting the neck vessels

• Obtaining a healed wound

• Restore function

• Restore swallowing

• No leaks

• Aesthetics

• Flaps reduce complications by:

– Obliterating dead space

– Recruiting healthy well-vascularized tissue into the region, which has commonly been irradiated and contaminated

– Tension free closure

– Interposing flap skin between irradiated wound edges

Pharyngeal defects

• Partial defects

– Pectoralis major flap with muscle and skin

– Radial forearm free flap

• Circumferential defects

– Tubed radial forearm flap or ALT flap

– Jejunum

Goals of reconstruction:

• A single stage, reliable reconstruction

• Prompt discharge from hospital

• Return of swallowing and speech function

• No salivary fistulas

Literature Review

• Nelligan (J PlastReconstrAesthet Surg. 2008) reported a fistula rate of:

– 13% for all fasciocutaneous flaps

• ALT flap 16.4%

• radial forearm free flap 14.4%.

– Jejunum 9.4%

• Charing Cross Study (Moradi et al)

– fistula rate: 2/43 (4.7%)

– stricture rate: 6/43 (14%)

Voice Restoration (Charing Cross

series)• 22 of 42 received a

primary (TEP)• 14 of 42 received a

secondary TEP • 36/42 (85%) received

either a primary or secondary TEP

• Voice was reported as:– Good in 17 of 39– Fair in 11 of 39. – 28 of 39 (72%) used their

tracheoesophagealpuncture as their primary mode of communication

When to eat?

• No scientific evidence on the timing of oral intake

• Err on the side of caution if previous radiotherapy

• Day 10

Mandible reconstruction

• Osteoradionecrosis (ORN) is a condition of non-vital bone in a site of radiation injury

• Characterised by:– hypovascularity– hypocellularity– hypoxia

• ORN occurs when, in the process of otherwise normal turnover of bone, the degradative function exceeds new bone production

• Can be either spontaneous or the result of an insult

Facial reanimation

• Goal of treatment

– Rest symmetry

– Facial function

– Voluntary function

– Spontaneous movement

– Absence of synkinesis

Facial reanimation

• Static vs dynamic

• Static: Divide face into 1/3rds

– Upper:

– Middle:

– Lower:

Dynamic: free gracilis

Static: slings

Tongue reconstruction

• Depending on extent of defect and the status of the floor of mouth

• Generally use:

– Radial forearm free flap

– Ulnar forearm free flap

– ALT
