CO2
laser is widely used in gynecology, especially to treat diseases of the lower genital tract, due to its affinity for cellular water
and controlled thermal effect. It is effective in the treatment of cervical, vaginal, and vulvar neoplasms, as well as anogenital
warts. In Brazil, its use started 30 years ago, and today the technology has expanded due to cost reduction. The laser is also
indicated for genitourinary syndrome in postmenopausal women, helping regenerate the vaginal mucosa and improving
symptoms such as dryness and dyspareunia. It is used in procedures like Bartholin’s cyst marsupialization and labiaplasty.
In postmenopausal treatment, the laser stimulates collagen production and restores vaginal pH. For the vulva, the technique
requires local anesthesia, with specific post-operative care. Additionally, it is important to follow the equipment usage guidelines
to avoid thermal complications.
