Midline Nasal Masses

Sharen J. Knudsen

Evaluation of a midline nasal mass requires a systematic approach. Knowledge of embryology of the nose and midface aids in understanding the origin of congenital midfacial deformities that manifest as nasal masses. A congenital mass mandates a differential diagnosis different from that of an acquired nasal mass. An acquired mass may be infectious, inflammatory, or neoplastic in origin. This chapter describes pathologic conditions of the nose and midface and delineates the essential elements of incidence, history, and physical examination necessary for generating a diagnosis and treatment strategy.
