Complications of Cosmetic Surgery: A Review

Every honest informed consent runs through this page. Cosmetic surgery is, in aggregate, safe in healthy patients at accredited facilities, and it is not risk free, and both facts deserve equal airtime. This hub gathers the real complication numbers, the mechanisms procedures share, and the early warning signs that turn a dangerous event into a treated one.

Large database studies give us honest benchmarks. Read them as orders of magnitude, not guarantees; individual risk varies with health, surgeon, and setting.

The pattern is consistent: single procedures in healthy patients run low, and combining procedures multiplies risk, the throughline of the combination evidence (Grade B). Procedure specific detail lives in each review: rhinoplasty, facelift, and blepharoplasty (all Grade B).

Most complications recur across procedures because they share mechanisms:

• Hematoma: blood collecting under the skin, usually in the first 24 hours, the single most common major complication in facial and body surgery. Blood pressure control and early follow up are the guards; one sided painful swelling is the signal.
• Seroma: fluid collection, classic after abdominoplasty and liposuction, managed by technique (progressive tension sutures, compression) and sometimes drainage.
• Infection: uncommon and usually treatable; nicotine, diabetes, and combined procedures raise it.
• Wound healing problems and scars: concentrated at tension points; dramatically worse with smoking; scar quality managed per Scar Management.
• Nerve events: temporary numbness is near universal; temporary weakness (facial branches after facelift, marginal mandibular after neck lift) usually recovers; permanent injury is rare and experience dependent, as in slow eye closure after facelift (Grade C).

Rare but grave complications deserve to be named plainly, because recognizing them saves lives:

• Venous thromboembolism (blood clots): deep vein clots that can travel to the lungs, the reason early walking and clot prevention protocols are core to abdominoplasty and long cases.
• Fat embolism: the defining danger of gluteal fat grafting, driven by injection plane, addressed by the subcutaneous only, ultrasound guided technique in the BBL safety evidence (Grade B).
• Retrobulbar hemorrhage: bleeding behind the eye after blepharoplasty, roughly 1 in 2,000, an emergency because vision is time dependent.
• Local anesthetic toxicity, airway and anesthesia events: covered in Anesthesia, clustering in under resourced settings.
• Device specific: the implant long horizon file (BIA-ALCL, breast implant illness, rupture) in Breast Implant Safety.

The evidence keeps pointing at the same levers, most of them decided before surgery: nicotine cessation (Grade A, Preop Preparation); an accredited facility and a dedicated anesthesia provider (Patient Safety); a board certified surgeon operating within their expertise; moderation in combining procedures and operative time; blood pressure and medical optimization; and honest disclosure of health and medications, including GLP-1 drugs (Grade B). None of these are glamorous; all of them move outcomes more than technique branding.

Call your surgeon for fever, spreading redness, escalating or one sided pain, wound drainage, or rapidly increasing swelling. Go to emergency care immediately for shortness of breath, chest pain, coughing or lightheadedness after a BBL, one sided calf swelling, severe one sided eye pain or vision change after eyelid surgery, uncontrolled bleeding, or confusion. Our emergency guidance is the front door for any of these.

• Grade B: the procedure complication benchmarks (facelift 1.8 percent, abdominoplasty 3.1 alone and 10.4 combined, liposuction 1.16, rhinoplasty and blepharoplasty profiles); combination limits; BBL safety mechanism.
• Grade C: nerve recovery timelines; several device incidence estimates.
