ROJAS BRUZON, Raquel et al. Morphometric study of mitosis and epithelial height, in facial skin exposed to photo damage. ccm [online]. 2018, vol.22, n.1, pp.90-103. ISSN 1560-4381.

Introduction: Facial cutaneous aging is a result of the factors that cause it. Sun exposure, smoking, genetic factors, gravity effects and muscle trophy lost. They are divided in two groups: intrinsically and extrinsically. Objective: to widen the knowledge about the photo- damage in Holguin´s population. Methods: a longitudinal prospective study at Vladimir Ilich Lenin Hospital, within September 2012 and September 2015. Characterization of patient according to age, sex, skin type and skin colour. Biopsies of morphometrical study of epithelial height and mitosis number. Results: most present age groups were: 40 - 49, for 43.3% y and 50 - 59 years old, pointing a 50%. A higher number of dry cutis and white skin patients were found in group III, and the morphometric changes of epithelial level was significant in the pre- auricular region, in relation to post- auricular region. The change in pre- auricular and post- auricular region, was not significant in relation to the number of mitosis. Conclusions: In present studies, facial cutaneous aging is a condition of age, sense and colour skin. Number of mitosis was influenced by age in pre and post- auricular region. Epithelial height was affected in pre- auricular region by photo- damage too.
