[Cervical dysplasia and their treatment with the CO2 laser (author's transl)].

The authors expound on their protocol for the treatment of dysplasias using the CO2 laser after they have reviewed the classification of dysplasia which is at the present time undergoing a lot of controversy. The indication for treatment is basal essentially on the site of the dysplasia in relationship to the endocervical canal. An exocervical lesion call for CO2 treatment with removal of a piece for histological examination and an endocervical lesion equally calls fro conisation carried out with the CO2 laser. A study of the post-operative appearances shows that clinically, colposcopically, cytologically and histologically, scar formation is perfect in 3 weeks due to centripetal metaplasia without spread from the zone of junction. It is essential to understand colposcopy perfectly before starting this from of treatment.
