This comprehensive guide discusses the most frequent defects encountered in the surgical treatment of head and neck cancer, showcasing real clinical cases. It consistently highlights the clinical image and the histological diagnosis and outlines the key points to be considered when choosing the reconstruction technique. Each chapter delves into a specific surgical technique, offering a deep dive into its principles, applications, advantages, and outcomes. It also includes follow-up and short- and long-term results. From the Facial Artery Musculomucosal Flap (FAMM Flap) to the Gastric Pull-Up, the work presents reconstructive procedures using microsurgical and locoregional pedicled flaps, through a collection of 108 clinical cases, each accompanied by detailed descriptions, videos and over 500 stunning original surgical illustrations. Head and Neck Reconstructive Surgery is an essential resource for head and neck surgeons, plastic surgeons, cancer surgeons, oncologists, and anyone involved in restoring both form and function to patients with complex head and neck defects.
