Cervical intraepithelial neoplasia (CIN) and microinvasive carcinoma of the cervix are considered the most intesting in the study of cervical neoplasia. The increase frecuency of this diagnosis, and the decrease in the number of cases of invasive carcinoma are related with expansion of the cervical citology (1). Evaluation of the patient with abnormal citology comprises, in addition to general and ginecological examination, the colposcopic inspection and byopsis of the cervix and, occacionally endocervical curetage and conization. The use of conization is decreasing with the increase of colposcopy (1,2,3,6). The coplposcopy can valorates the changes of the cervix that are related with the disease of cervix neoplasia; their characteristics and extension are helpful for the delimitation and identification of the invasive cencer (1). So the colposcopy can help to valorate the disease extension, leaving the conization only for some cases, wich oscilates between 10ù/. to 15ù/. in women under 45 years. In Solca Quito, besides colposcopy, the conization continues being a routine method for patients with CIN, method that we think is overused and increases morbility and cost in the patients management.
