This book provides up-to-date information on nasal vestibule malignancies, outlining the specific clinical history and pattern of spread. It also describes the flaws in TNM staging, which can be attirbuted to factors ranging from the anatomy to the definition of the main prognostic parameters.Nasal vestibule malignancies are associated with a peculiar oncological history, but there are also clear issues related to the reconstructive phase following ablative surgery due to the anatomic peculiarities.  Such issues deeply impact the cosmetic and functional results, and hence the quality of life of surviving patients.Additionally, the book describes novel evidence on treatment outcomes for these malignancies in terms of both oncological and functional results. It proposes a new standard based on interstitial HDR brachytherapy for the primary lesion and on surgery for regional metastases.
