This chapter discusses benign neoplasms of the nose and paranasal sinuses, where benign tumors of the nasal cavity and paranasal sinuses represent a wide spectrum of distinct histopathologic entities. Management begins with comprehensive history and physical examination with focus on nasal endoscopy. Facial sensation, baseline vision, and sense of smell should all be evaluated prior to surgical intervention. Tumor resection needs to be tailored to each individual surgical case. Emerging techniques have resulted in shifts in preoperative analysis, treatment, and surgical resection. A multitude of staging systems have been introduced and subsequently revised to describe tumor extent and provide clinical risk stratification for recurrence rates, morbidity, and mortality. Hemangiomas are rare, vascular tumors of the sinonasal tract that most commonly involve the nasal vestibule and nasal septum with reports of paranasal sinus origin. Hamartomas are defined as benign masses of disorganized mature cells of any tissue type.
