How are risks assessed in aesthetic surgery? Why informed consent matters

In short: Risk in aesthetic surgery is assessed on three levels: general risks that apply to every operation, risks specific to the planned procedure, and personal risk factors arising from your own health. Informed consent is the process in which these risks are discussed openly before surgery, your questions are answered and you decide without pressure; the signed form is only the written record of that process.

Most aesthetic operations are planned and elective. That makes it both possible and necessary to take time over the decision: unlike emergency surgery, the potential benefits and the risks can be weighed calmly. No surgical procedure is free of risk. The goal is not to downplay risk, but to identify it correctly, reduce it where possible and make sure the patient can make an informed choice.

This article covers general surgical risks, procedure-specific risks, personal risk factors and how informed consent works in practice. The information here is general; an individual’s actual level of risk varies from person to person and can only be established through a physician’s examination, a detailed medical history and the necessary tests.

General risks that apply to every operation

Whatever the procedure, any operation that involves a skin incision and anaesthesia carries certain shared risks. How often they occur and how significant they are depends on the individual and the procedure:

• Bleeding and haematoma: blood can collect in the tissues during or after surgery (a haematoma). Small collections may be reabsorbed on their own; larger ones sometimes need to be drained in a further procedure. Uncontrolled high blood pressure and medicines that increase bleeding can raise this risk.
• Infection: despite sterile conditions and preventive antibiotics where indicated, a wound infection can develop. Redness, increasing pain, warmth and discharge should be reported to the surgeon.
• Wound-healing problems: the wound edges may separate, closure may be delayed, or the blood supply at the skin edge may be compromised. Smoking, diabetes and long incisions under tension increase this risk.
• Scarring: every skin incision leaves a scar. How a scar matures over time depends on genetics, skin type, body area and aftercare; some people develop thick (hypertrophic) scars or keloids.
• Anaesthesia-related risks: these range from mild effects such as nausea and a sore throat to rare but serious breathing and circulatory problems. The type of anaesthesia is decided after the anaesthetist’s pre-operative assessment.
• Thrombosis: immobility and long operating times can encourage a blood clot in the leg veins (deep vein thrombosis) that may travel to the lungs (pulmonary embolism). Early mobilisation, compression measures and, where appropriate, preventive medication aim to reduce this risk.

A realistic assessment of general risk comes from discussing your own situation rather than memorising figures found online. Published numbers come from different patient groups and different techniques, so they cannot be applied directly to one individual.

Procedure-specific risks

Alongside the general risks, every operation has its own possible problems, and these should be addressed separately in the consent discussion. Some examples:

• Rhinoplasty (nose surgery): nasal obstruction or changes in breathing, asymmetry, prolonged swelling, a shape that does not fully match expectations, and the possibility of revision surgery.
• Breast surgery: temporary or permanent changes in nipple and skin sensation, asymmetry and, when implants are used, capsular contracture (hardening of the capsule around the implant) and the need for long-term follow-up; with some procedures, a possible effect on breastfeeding.
• Tummy tuck (abdominoplasty): seroma (a collection of fluid in the tissues), healing problems at the navel or along the incision, reduced sensation in the lower abdomen, and expectations regarding scar position and quality.
• Liposuction: contour irregularities or rippling, more visible skin laxity, and fluid-balance considerations when large areas are treated.
• Facelift: usually temporary weakness of facial nerve branches, altered sensation around the ears, and issues related to the hairline and scar placement.

Procedure-specific risks vary with the technique used, the size of the area treated and whether several procedures are combined in one session. That is why two people undergoing an operation with the same name can have quite different risk profiles.

Personal risk factors: what makes your situation different

The most individual part of risk assessment is the patient’s own health. During the consultation and history-taking, the following factors are explored in detail:

Previous operations and scar behaviour, allergies, recent rapid weight loss, nutritional status and expectations are also taken into account. Unrealistic expectations are not a medical complication, but they are an important reason for dissatisfaction after surgery, so they deserve an honest conversation at the consultation.

How does informed consent work?

Informed consent means that the patient decides freely after receiving information about the planned procedure in language they can understand. In Türkiye, patients’ rights legislation also protects the right to information and the right to give or refuse consent. Consent is not just a signature; it is a two-way conversation.

A thorough consent discussion usually covers:

• What the proposed procedure is and which problem it aims to address
• The expected benefits and their limits
• General and procedure-specific risks, possible complications and what would be done if they occur
• Alternatives: other surgical methods, non-surgical options and the consequences of having no treatment
• The type of anaesthesia, the recovery process and factors that may affect the return to daily life
• Follow-up appointments and how things would proceed if a correction became necessary

Patients have the right to ask questions, to take time to think and to withdraw consent at any point before the operation begins. Seeking a second opinion from another doctor is a normal and legitimate step and can make the decision easier, especially when a plan involves several procedures. Reading the consent form carefully before signing, asking about unfamiliar terms and requesting a copy are all part of a patient’s rights.

What can be done to reduce risk?

Risk can never be eliminated completely, but there are concrete steps patient and surgeon can take together:

1. Give a complete and honest medical history: all medicines and supplements, smoking and alcohol habits, previous operations.
2. Complete the requested blood tests and any other specialist assessments.
3. Follow instructions on fasting, medication adjustments and stopping smoking before surgery.
4. Move as advised in the early post-operative period and follow guidance on compression garments and wound care.
5. Know the warning signs and contact your doctor without delay if they appear.
6. Attend all follow-up appointments.

Frequently Asked Questions

Is aesthetic surgery less risky than other types of surgery?

Aesthetic procedures are real operations, and all general surgical risks apply to them as well. Because they are planned, there is time to prepare the patient and to improve modifiable risk factors beforehand. However, an aesthetic purpose does not make the risk trivial; every operation should be assessed with the same seriousness and the same attention to the individual’s health.

Can I change my mind after signing the consent form?

Yes. Consent can be withdrawn at any stage until the operation begins; simply telling your doctor that you have changed your mind is enough. This right applies even if a form has already been signed. Asking in advance about any practical or scheduling consequences of withdrawing helps avoid surprises and makes the decision less stressful.

How long before surgery should I stop smoking?

The period is set by the surgeon according to the procedure and your health. For lifting operations in which large areas of skin are moved, tissue blood supply is critical, so a stricter approach may be taken. E-cigarettes and other nicotine products can have a similar effect on blood vessels and are usually treated the same way.

Does getting a second opinion mean I do not trust my surgeon?

No. A second opinion is a normal part of patients’ rights and can make it easier to decide, particularly before extensive surgery. When comparing recommendations, it helps to look at the reasoning behind each approach, how clearly the risks were explained and whether alternatives, including not operating, were discussed.

Which symptoms after surgery should be reported straight away?

Shortness of breath, chest pain, a painful swollen leg, high fever, rapidly increasing swelling on one side, foul-smelling wound discharge or darkening of the skin should all be reported to your doctor without delay. Rather than taking medication on your own, use the contact route you were given after surgery.
