Abstract

Progressive hemifacial atrophy, also known as Parry-Romberg syndrome, is an uncommon degenerative and poorly understood condition. It is characterized by a slow and progressive atrophy affecting one side of the face. The incidence and cause of this alteration are unknown, and the pathogenesis of the syndrome is not clear. Some authors attribute the atrophy of the subcutaneous system to an alteration of the sympathetic system. Others attribute it to an alteration of the nervous system at the encephalic level or to an interstitial neuritis of the trigeminal nerve. The most common complications that appear in association with this disorder are trigeminal neuritis, facial disorders, and epilepsy. The latter is the most frequent complication of the central nervous system. Characteristically, the atrophy progresses slowly for several years and soon becomes stable. After stabilization of the disease, plastic surgery of autogenous fat grafts can be performed. This study aimed through the presentation of clinical cases to suggest a therapeutic plan comprised of two sequential treatments: aquisition of platelet gel from a small volume of blood (9 ml) followed by the Coleman technique for reconstructing the three-dimensional projection of the face contour, restoring the superficial density of the facial tissues. The results obtained prove the efficacy of these two treatments combined, and the satisfaction of the patient confirms the quality of the results.
