CO₂ laser labiaplasty

A guide to understanding CO₂ laser labiaplasty

Labiaplasty is a surgical procedure primarily intended to reduce or reshape the labia minora. The CO₂ laser can be used as a surgical instrument to excise tissue and simultaneously coagulate small blood vessels, but its use does not make labiaplasty a non-surgical procedure.

The technique and the amount of tissue to be modified are determined individually, taking into account the patient’s anatomy, symptoms and agreed treatment goals.

Vulval anatomy varies considerably

The size, shape, colour and symmetry of the labia vary widely between women and may also change throughout life. Visible, asymmetrical or larger labia minora do not, in themselves, constitute a medical condition.

Labiaplasty may be considered when physical symptoms are present, such as chafing, discomfort during certain activities or pain caused by friction. It may also be considered when an adult woman wishes to change the appearance of her genital area after receiving appropriate information about the procedure, its potential outcomes and its limitations.

Assessment before labiaplasty

Before surgery, it is important to carry out a gynaecological examination to assess the vulval anatomy, symptoms and reasons for seeking treatment.

The patient’s medical history, current treatments, previous surgery and any other circumstances that could affect the procedure or wound healing are also reviewed.

The preoperative assessment provides an opportunity to agree with the patient which changes can reasonably be achieved and to explain the postoperative recovery process and possible risks.

Before undergoing an aesthetic surgical procedure, it is important to understand what it involves, its potential complications and the follow-up care required.

What are the benefits of using a CO₂ laser during surgery?

During labiaplasty, the CO₂ laser can be used as an instrument for cutting and coagulation. Laser energy allows tissue to be excised while controlling bleeding from small blood vessels, thereby reducing bleeding during the operation.

A systematic review and meta-analysis published in 2024 found a lower incidence of bleeding, swelling and haematoma formation with laser techniques compared with procedures performed using a scalpel.

However, the outcome of labiaplasty does not depend solely on the instrument used. The choice of surgical technique, knowledge of the anatomy and the specialist’s experience are fundamental factors.

How is the procedure performed?

Surgery is planned according to the patient’s anatomical characteristics and the tissue requiring reshaping. The laser allows tissue to be excised while simultaneously controlling bleeding. The surgical site is then closed using absorbable sutures.

The procedure can be performed under local anaesthesia with sedation or, in certain cases, under general anaesthesia. It is usually carried out as day surgery, allowing the patient to return home on the same day.

The specific surgical protocol is adapted to each patient.

What can be expected during recovery?

During the first few days, swelling, tenderness, discomfort and small bruises are common in the treated area. These symptoms gradually subside as healing progresses.

The time needed to return to work and daily activities depends on the patient’s recovery and the type of activities involved. Although many activities can be resumed earlier, the tissues need several weeks to complete the initial stages of healing.

During this period, patients should follow the specialist’s recommendations regarding hygiene, clothing, exercise, bathing and sexual intercourse.

Possible risks and complications

Although most labiaplasty procedures are not followed by significant complications, labiaplasty is a surgical intervention and, as such, carries certain risks.

Possible complications include bleeding, infection, partial wound separation, haematoma formation, wound-healing problems, residual asymmetry, changes in sensation or the need for further corrective surgery.

The specific level of risk depends on several factors, including the technique used, the patient’s individual characteristics and the progression of wound healing.

Can labiaplasty affect sensation or sexual intercourse?

One of the aims of surgical planning is to preserve the anatomical structures and sensitivity of the area.

Published studies generally report high levels of patient satisfaction, and some have observed improvements in genital self-perception and certain measures of sexual function following surgery. However, many of these studies are observational, and the quality of the evidence regarding long-term outcomes remains limited.

Labiaplasty should therefore not be presented as a procedure that guarantees improved sexual function. Expectations and treatment goals should be discussed individually during the preoperative consultation.

Could further corrective surgery be necessary?

Wound healing and the final shape of the tissues take time to stabilise. Minor differences between the two sides may persist after surgery without necessarily constituting a complication.

In selected cases, a further corrective procedure may need to be considered because of residual asymmetry, wound-healing problems or other concerns. This decision should only be made once the tissues have healed sufficiently for the specialist to assess the final outcome appropriately.
