The cancers which affect the throat, mouth, sinuses or nose are classified as head and neck cancers. There are various treatment options for this type of cancer such as surgery, radiation therapy, targeted therapy, immunotherapy and chemotherapy. Surgical treatment involves removing the cancerous tumor and some surrounding healthy tissue. One of the major advancements in head and neck cancer surgery is virtual surgical planning (VSP). It refers to a type of pre-operative planning technique that uses 3D imaging computer software to visualize a surgical procedure. 3D reconstruction of complex head and neck cancers can reveal crucial details like tumor location, range of invasion and blood supply. It also offers the possibility of preoperative simulation for complex defect repair. This book aims to shed light on some of the advancements in surgical otolaryngology related to head and neck cancer surgery. The readers would gain knowledge that would broaden their perspective in this area of medicine.
