Silvio Ascione

Schönheitschirurg/-in
18 Jahre der Erfahrung

I was born in Naples, born in 1981, and I have the best job in the world. Imagine waking up every morning and knowing that on that day you will make someone's dream come true: you will change a man's life forever, you will give birth to a new woman, you will help a girl achieve happiness, a boy gain self-confidence. I am Silvio Ascione, specialist in Plastic, Reconstructive and Aesthetic Surgery. Son of art, from my father, a great man and great plastic surgeon, I learned the complex and enchanting magic of aesthetic plastic surgery. Nourished by art and medical knowledge, I grew up in operating theatres, always behind my father's back who, like the best of masters, passed on to me, a young disciple, the passion for a profession in which art combines to science to create masterpieces. Graduated in Medicine and Surgery in 2005 from the Second University of Naples, qualified in the first session of 2006 and specialized in Plastic, Reconstructive and Aesthetic Surgery at the School of Specialization of the Second University of Naples directed by Prof. Francesco D'Andrea, I am enrolled in the 'Order of Surgeons of Benevento and I obtained a Master's degree in Oncoplastic Surgery and integrated treatments at the University of Genoa.

My experience in the surgical room, however, began much earlier, and it was an intense, very hard journey, characterized by total dedication, constant updating, continuous training: initially internal at the Department of Plastic, Reconstructive and Aesthetic Surgery of the S.U.N., I frequented then the Department of Reconstructive and Aesthetic Plastic Surgery of the Mediterranean Clinic of Naples affiliated with the “Tor Vergata” University of Rome, the A.O.R.N. Major Burns Center Department, directed by Prof. Roberto D'Alessio, the Trauma Center Department of Prof. Antonio Martin.

 

I regularly participate in all the main national and international Plastic Surgery conferences to stay constantly updated on the technological innovations offered by the market, the cutting-edge products and instruments to be used for my treatments, the new research and the most recent studies in the field of plastic and aesthetic surgery.

I studied and carried out in-depth internships at universities and hospital centers in Spain, France and North America, gaining extraordinary experience on the most advanced surgical techniques, in particular on facial and breast rejuvenation.

MY MISSION

My innate passion for surgery, my attention to the care of the image and the harmony of forms, my obsessive precision and attention to detail, my unstoppable research and updating activity, my decades of experience in the most varied spheres of plastic and aesthetic surgery, working side by side with my specialized team, allow me today to boast a curriculum full of successes and satisfactions and to be able to offer my patients a detailed and scrupulous visit, a precise diagnosis, a treatment plan personalized and efficient intervention, agreed on the basis of the patient's needs and desires, highly effective personal techniques and tools to eliminate all types of blemishes, signs of aging or congenital imperfections, through increasingly less invasive interventions and with increasingly natural results.

Experience, professionalism, harmony, naturalness: these are the four key points on which I build a relationship that is first human, then professional, with my patient. The choice of plastic or aesthetic surgery does not only involve the decision to undertake a path of external change. For this reason I dedicate myself with dedication and attention to listening to the discomforts and wishes of each of my patients, so that we can plan together the most appropriate intervention for their needs and to achieve the expected result and to accompany them step by step towards a path of external and internal rebirth
