What does it treat?
Loose skin along the outer chest, often below the underarm.
It may be considered after weight loss or when skin folds persist despite a stable weight.
Breast & Chest
Lateral Chest Wall Skin Excision
Lateral chest wall skin excision removes loose skin along the sides of the chest to improve contour near the underarm.
Will there be a scar?
Yes. Removing skin requires a permanent incision scar.
Its length and position depend on the fold and the amount of skin removed; clothing may not always cover it.
Is this a breast lift?
No. It targets the side of the chest rather than lifting the breast itself.
A breast lift, reduction, or other contouring procedure may be discussed separately if needed.
01 · Overview
Understanding lateral chest wall skin excision
Lateral chest wall skin excision focuses on a fold of loose skin along the side of the chest. It can be a localized operation or part of a broader body-contouring plan after weight loss. [1]
The surgeon removes a planned section of skin and, when appropriate, some underlying fat, then closes the edges. The incision follows your anatomy and the direction of skin looseness. Ask to see where the scar would sit with your arm both lowered and raised.
This is different from liposuction, which removes fat but does not directly remove loose skin. It is also different from a breast lift, arm lift, or upper back lift, although neighboring areas may need to be considered together. [2]
- Target area
- Outer chest near the underarm
- Main approach
- Surgical removal of excess skin
- Anesthesia
- Depends on the extent and combined procedures
- Main tradeoff
- Less loose skin with a permanent scar
Could the fullness be something other than loose skin?
Yes. Fat, tissue extending from the breast toward the underarm, and other causes of swelling can look similar. A new lump, one-sided change, or unexplained pain should be medically evaluated rather than assumed to be a contour concern.
Why does the plan vary between people?
A small fold beside the chest needs a different approach from skin that continues into the arm or back. Skin quality, previous scars, and how much tension closure would create also affect the plan.
02 · Concerns & Goals
What brings people to a consultation
Loose skin beside the breast or chest can affect clothing fit and comfort. Your surgeon can help distinguish excess skin from fat or breast tissue.
A fold beside the chest
Loose skin may gather below the underarm or along the outer edge of the breast or chest.
Clothing fit
A fold may show around a bra, fitted shirt, or sleeveless top. Surgery may change the contour, but cannot ensure a particular clothing fit.
Rubbing or irritation
Skin-on-skin contact may be uncomfortable. Persistent rashes need assessment and treatment, whether or not you choose surgery.
Uneven side contours
Differences between sides may be noticeable. Surgery may reduce them, but some asymmetry usually remains.
03 · Options
How the approaches differ
These are planning approaches, not interchangeable treatments. A surgeon can explain which, if any, fits your anatomy and priorities.
Localized skin excision
Removes a defined fold along the lateral chest.
How it worksA section of loose skin is removed and the edges are closed.
May suitMay suit a localized fold without extensive looseness in neighboring areas.
Main tradeoffLeaves a permanent scar and may leave fullness outside the treated area.
Excision with liposuction
Addresses both excess skin and selected fat deposits.
How it worksLiposuction may refine nearby fullness while excision removes loose skin.
May suitMay suit people whose side-chest contour reflects both skin and fat.
Main tradeoffAdds treatment and can increase swelling or contour irregularity; liposuction alone cannot replace needed skin removal.
Extended skin excision
Treats a fold that continues toward the back or underarm.
How it worksThe removal pattern extends to address connected areas of loose skin.
May suitMay suit broader laxity that a short incision would not adequately address.
Main tradeoffUsually requires a longer scar and may involve more recovery restrictions.
Combined or staged contouring
Coordinates side-chest treatment with a separate breast, arm, or back procedure.
How it worksProcedures may be done together or in separate operations after a safety assessment.
May suitMay suit people with concerns spanning several neighboring areas.
Main tradeoffCombined surgery increases the scope of one recovery; staging means separate operations and recovery periods.
Body-contouring and liposuction guidance explains the general principles behind these choices. Your lateral chest wall incision and treatment boundaries require an individual examination. [1] [2].
Can the incision always stay hidden in a bra line?
No. A garment line may help guide placement, but the fold's location and safe closure matter more. Ask which parts may be visible in your usual clothing.
Is a shorter scar always better?
Not necessarily. A shorter incision may leave loose skin or bunching at the ends. Discuss the balance between scar length and how much contour change is realistic.
04 · Results
What may improve and what may remain
Contour and comfort
The aim is less overhanging skin along the side of the chest.
- Clothing may sit differently as swelling settles.
- Relief from rubbing depends on its cause and the area treated.
- Perfect symmetry or a completely flat contour is not assured.
Scars and settling
The scar is permanent, and the early appearance is not the final result.
- Swelling and temporary puckering can affect the initial contour.
- Scars may soften and fade over many months, but can remain wide, raised, or noticeable.
- Your surgeon will explain when scar care is appropriate.
Longer-term changes
Weight changes and aging can alter the result.
- Maintaining a stable weight helps limit future stretching.
- Residual loose skin or unevenness may remain.
- Revision may be considered after healing, but adds risks and cost.
General body-contouring guidance describes lasting contour changes alongside permanent scars and ongoing effects of aging. It does not predict an individual's result. [1]
05 · Recovery
Planning your recovery
Recovery at a glance
- Stay after surgery
- Determined by Your Surgeon
- Initial recovery at home
- Varies by Individual
- Return to desk work
- Varies by Procedure and Work Activity
- Light daily activities
- Based on Individual Recovery
- Strenuous exercise
- Based on Surgeon Clearance
Returning to work does not mean fully healed. Follow your surgeon’s instructions; strenuous activity requires clearance.
Recovery depends on the length and location of the incision and any combined surgery. Your surgical team's instructions take priority over general timelines.
Step 1 · Day of surgery
Treatment day
The team monitors you after anesthesia and reviews dressings, pain control, and any drains. Whether you go home that day depends on the operation and your health.
Step 2 · First several days
Early healing
Soreness, swelling, bruising, and a pulling sensation may occur. Your team will explain how to protect the incision during sleep, dressing, and arm movement.
Step 3 · Following weeks
Gradual return
Activity increases as the wound heals and your surgeon clears you. Returning to work does not mean the incision has regained full strength.
Step 4 · Following months
Scar and contour maturation
Swelling gradually settles and scars continue to change. Follow-up helps assess healing, comfort, and any persistent contour concerns.
Planning everyday activities
ActivityGeneral planning contextWhat affects the plan
Desk workPlanning context: Some people can resume light work within a week or two; larger operations may require longer.What affects it: Pain, fatigue, drains, and reaching demands can delay return.
DrivingPlanning context: Resume only when cleared and able to steer, turn, and brake safely without impairing medication.What affects it: Chest discomfort and limited arm movement can affect vehicle control.
Lifting and exercisePlanning context: Ask for separate clearance for lifting, overhead reaching, and strenuous exercise. [1]What affects it: These movements can pull on the side-chest incision.
Bathing and swimmingPlanning context: Follow your team's timing for showering and wait for clearance before soaking or swimming.What affects it: Open areas, dressings, and drains change what is safe.
These are discussion points, not a personal recovery schedule. Combined procedures may set stricter limits.
Before your procedure
- Discuss your health history, previous chest or breast surgery, and any new breast or underarm symptoms.
- Review all medicines, supplements, and allergies; change medications only as instructed.
- Discuss nicotine use and the team's requirements for stopping before and after surgery.
- Review weight stability, nutrition, and any concerns after major weight loss.
- Arrange transportation and help at home based on your anesthesia and treatment plan.
- Ask for written instructions covering wound care, movement limits, follow-up, and after-hours contact.
Will I need drains or a compression garment?
Possibly. This depends on the space created under the skin and the extent of treatment. Ask whether either is planned and how the team will decide when it can be stopped.
What if arm movement pulls on the incision?
Ask your team which movements are allowed and how to dress and sleep comfortably. Do not force a painful stretch or assume that keeping the arm completely still is necessary.
06 · Safety
Risks and what your clinician assesses
Temporary soreness, swelling, bruising, tightness, and altered skin sensation can occur. Symptoms should generally improve; worsening pain or swelling deserves a call to your surgical team.
Bleeding or fluid collection
Blood or clear fluid can collect beneath the skin and may require drainage or another procedure.
Infection
An infection may need antibiotics, wound treatment, or further surgery.
Delayed healing or skin loss
The incision can separate or areas of skin may heal poorly, especially when blood supply is reduced.
Noticeable or uncomfortable scars
Scars can widen, thicken, or cause tightness, including during arm movement.
Sensation and contour changes
Numbness, persistent pain, unevenness, residual folds, or differences between sides may remain and sometimes prompt revision.
Anesthesia and blood clots
Anesthesia complications and clots in the legs or lungs are uncommon but potentially serious surgical risks.
Discuss these risks and your individual health history with your surgeon. [1]
What your clinician assesses
- The amount of loose skin, underlying fat, and involvement of nearby breast, arm, or back tissue.
- Skin quality, existing scars, and how closure may affect arm movement.
- Health conditions, nicotine exposure, medications, and anesthesia or clotting history.
- Weight stability, nutritional health, expectations, and available recovery support.
07 · Costs

Your written estimate should explain the services included, any separate charges, and payment terms.
08 · Questions
Common questions
Will this reduce breast size?
Not in the same way as breast reduction. It targets side-chest skin, although treatment near the outer breast can affect its outline. Clarify whether any breast tissue is included in the plan.
Can exercise remove the fold?
Exercise supports health and muscle strength, but does not directly remove excess skin. Weight changes may change fullness without eliminating a loose fold.
Does insurance cover it?
Coverage depends on your plan, the reason for surgery, and documentation. Cosmetic contouring is often excluded. Ask your insurer about its requirements before scheduling; authorization is not a guarantee of payment.
Should I wait until my weight is stable?
A stable weight generally helps planning and durability. Your surgeon can discuss timing based on weight changes, nutrition, and any future weight-loss plans.
