Led by Dr.Sultan Ahmed Pradhan, the person who introduced Head & Neck Onco surgery as separate entity during the days of domination by general surgical oncology in India. He also introduced voice conservation surgeries for laryngeal malignancies and gastric pullups in India. The Prince Aly Khan Hospital is a Diplomat of National Board (D.N.B) center for surgical oncology. This center has performed the largest series of Trans Oral Laser Surgeries for glottic, supra glottic and pyriform sinus cancers in India. The Centre gets approximately 14500 head and neck cancer cases as outpatients every year. Annually around 1350 major head & neck surgical procedures are done. Close to 600 cases of trans oral laser surgeries are done every year, which is the largest number for any cancer center in the country. Another 480 cases of other day care procedures like DL scopy, EUA are done every year. Dr.Sultan.Ahmed.Pradhan has published 1 internationally acclaimed textbook on voice conservation surgeries. He is an internationally acclaimed surgeon-par excellence.

At the Prince Aly Khan Hospital I was trained in head and neck onco surgery.
