Cheek advancement for near total lip loss

Bernard Flap

A Bernard flap rebuilds a lip when most of it has been lost, by sliding cheek tissue inward from both sides. Small triangles of skin are removed near the nose and mouth so the cheek travels without bunching up.

Quick answer

A Bernard flap is used when a very large part of the lip, sometimes almost all of it, has been lost. Cheek tissue on both sides is released and advanced towards the middle, with small triangles of skin removed so it slides flat instead of folding. Lining taken from inside the cheek forms the red part of the new lip.

Key takeaways
  • A Bernard flap is reserved for very large lip losses, where flaps from the opposite lip cannot supply enough tissue.
  • Cheek skin and lining are advanced towards the midline from both sides to rebuild the whole width of the lip.
  • Triangles of skin near the nose and mouth are removed so the advancing cheek lies flat instead of bunching.
  • The rebuilt lip is usually less mobile and less sensitive than the original, since muscle continuity is hard to restore.
  • Drooling and difficulty holding liquid are common early on and often improve with therapy and time.

Rebuilding a lip that is almost entirely gone

Some injuries and cancers take nearly the whole lip. Nothing useful remains to borrow from the opposite side, and a graft would give a thin, immobile patch that neither holds saliva nor looks like a mouth. Tissue therefore has to come from somewhere close by, in enough quantity to rebuild both the skin outside and the moist lining inside.

Cheeks supply that tissue. Cuts are made outward from the corners of the mouth and the cheek on each side is released so it can slide towards the middle. Small triangles of skin near the fold running from nose to mouth are taken out, which lets the cheek travel without gathering into a bunch. Mucosa from inside the cheek is then turned outward to form the red part of the new lip.

What this cannot fully restore is movement. Muscle brought in from the cheek does not act like the ring that once circled the mouth, so the rebuilt lip tends to be stiffer and less sensitive. Therapy, and sometimes a further procedure, is used to improve control.

When a Bernard flap is considered
✦Loss of most or all of the lower lip after removal of a large cancer
✦A severe crush or tearing injury that has taken the lip and nearby skin
✦Extensive damage from an animal bite involving both lip and cheek
✦Destruction of the lip by a deep, long standing infection
✦Failure of an earlier repair, leaving too little lip to work with
✦Burn injury that has taken both the lip and its inner lining

Signs that need urgent attention

Cheek tissue that looks dusky, cold or pale points to a struggling blood supply and needs same day review.
Bleeding inside the mouth that will not settle should be treated as an emergency.
Fever with swelling, redness or foul discharge suggests infection in a large wound.
Sudden opening of a stitch line, especially inside the mouth, needs prompt assessment.

Who this operation suits

This is a large reconstruction, chosen when smaller flaps cannot cover the loss. Honest discussion about movement and sensation matters before agreeing to it.

May be suitable when
✦Loss of most of the lip, beyond what cross lip flaps can replace
✦Healthy cheek tissue on both sides, free of scarring or radiation damage
✦Someone fit enough for a longer operation under general anaesthesia
✦A patient who understands that cover and containment come before movement
May not be suitable when
✦Smaller defects that other flaps rebuild with better movement and feeling
✦Cheeks already scarred, irradiated or involved in the disease process
✦Continuing tobacco use or poorly controlled diabetes, which threaten healing
✦Expectation of a mouth that moves and feels exactly as it did before

How the operation is carried out

01
Assessing what remains

The surgeon maps how much lip is missing, checks both cheeks for scarring and plans where the lining will come from. Photographs and measurements guide the design.

02
Releasing the cheeks

Cuts extend outward from the corners of the mouth and each cheek is freed so it can advance. Triangles of skin are removed to allow a flat slide inward.

03
Building the lining

Mucosa from inside the cheek is turned outward to form the red surface of the new lip, giving a moist edge rather than dry skin at the opening.

04
Joining in layers

Lining, muscle and skin are stitched separately so the repair has depth. Attention goes to the level of the new lip edge on both sides.

05
Planning what follows

Before discharge the team explains speech and swallowing therapy, the diet plan, and any refinement that may be considered once healing settles.

Recovery week by week

Day 1 to 3

Swelling of the cheeks and lip is marked. Feeding is usually with fluids, pain relief is regular, and the mouth is kept clean with gentle rinses.

Week 1 to 2

Swelling begins to fall and stitch lines settle. Soft food is introduced slowly, and leaking from the mouth is common at this stage.

Week 3 to 6

Most people manage a soft diet and return to light activity. Therapy for speech and mouth control usually begins in earnest around now.

Month 6 and beyond

Scars fade and the lip softens. Movement and containment improve gradually, and further refinement is discussed once the tissue is quiet.

What this operation can achieve

✦Closure of a very large defect using tissue that is close by and reliable
✦A moist lip edge built from cheek lining rather than dry skin
✦Restored separation between the mouth and the outside, protecting teeth and gums
✦Scars placed in the folds running from nose to mouth, where they settle reasonably
✦A stable base that later refinement can build on

What results are realistic

Expect a mouth that is closed, protected and workable rather than one that looks untouched. Containment of saliva usually improves over the first few months, helped by therapy. Movement stays limited, since the muscle ring cannot be fully rebuilt, and numbness in the new lip is common. Mouth opening may be tighter than before. Many patients find eating and speech improve steadily across the first year.

Risks worth knowing about

A reconstruction of this size carries more risk than a small flap, and the trade offs should be clear well before surgery.

Partial loss of an advanced flap if the blood supply is stretched too far
Drooling and poor control of liquid, particularly in the early months
Numbness of the rebuilt lip and chin, which may not fully recover
Wound breakdown or infection, especially where lining meets skin
A tight mouth opening that limits dental care and denture use

Looking after a large repair at home

Care at home is about protecting a big wound while slowly retraining the mouth to do its job again.

✦Follow the diet plan step by step, moving from fluids to soft food as advised
✦Rinse the mouth after every meal to keep the inner stitch lines clean
✦Use the exercises given by the therapist for closure, speech and swallowing
✦Keep away from tobacco and protect fresh scars from strong sunlight
✦Report any new leak, opening or foul discharge rather than waiting for review

What people often get wrong

MythA big enough graft could replace the whole lip
In practice

Grafts bring skin without muscle or lining. A lip built from graft alone stays stiff, dries out and cannot keep saliva inside the mouth.

MythThe new lip will move like the old one
In practice

Movement is the hardest thing to rebuild. This flap restores cover and containment first, and therapy then improves control as far as it can.

MythNothing more can be done once the lip is gone
In practice

Even near total loss can be reconstructed. What changes is the size of the operation and the honesty needed about how the result will work.

MythDrooling afterwards means the surgery failed
In practice

Leaking is common early on while swelling settles and muscle control is retrained. It usually improves over the following months with therapy.

Why families choose Elegance Clinic

Large lip reconstructions at Elegance Clinic in Surat are planned with the therapy team from the start, because how the mouth works afterwards depends as much on rehabilitation as on the operation itself.

✦Detailed discussion of what a large reconstruction can and cannot restore
✦A written estimate before admission and support with insurance approval
✦Speech and swallowing therapy arranged as part of the plan
✦Long follow up while scars mature and refinements are considered

Cost & insurance

Cost and insurance

Charges reflect a long operation, the hospital stay, anaesthesia and any tumour surgery carried out at the same sitting. Therapy afterwards adds to the total, and staged refinement is quoted separately when it is planned. Reconstruction after cancer or trauma is generally admissible under mediclaim, and the team helps assemble the paperwork. A written estimate is prepared once the defect has been assessed.

Charges reflect a long operation, the hospital stay, anaesthesia and any tumour surgery done at the same sitting. Therapy afterwards adds to the total. Because plans vary widely, a written estimate is prepared once the defect has been assessed.

Most policies cover reconstruction after cancer or trauma, as it restores function. Approval typically needs imaging, biopsy reports, photographs and a surgical plan. Since the stay is longer, room rent limits in your policy are worth checking well in advance.

It is a recognised reconstruction carried out under general anaesthesia, with fitness checked beforehand. Risks include bleeding, infection and partial loss of an advanced flap. Careful planning and close monitoring afterwards are how those risks are kept down.

Fluids come first, then soft food over several weeks. Leaking and drooling are common early and usually improve with therapy. Many people manage a soft normal diet within a couple of months, though tough food may stay difficult.

Movement is the hardest part to restore, because the muscle ring around the mouth cannot be fully rebuilt from cheek tissue. Closure and containment improve first, then therapy adds control. Expect a working mouth rather than a natural smile.

It is meant for very large losses. Smaller gaps do better with flaps that preserve movement. Cheeks that are scarred or previously irradiated, uncontrolled diabetes and continuing tobacco use all argue against proceeding until things improve.

Expect measurement of the defect, examination of both cheeks, photographs and a discussion of what the result will and will not do. Therapy needs are raised early. Bring imaging, biopsy reports and details of any previous surgery.
