[Symptoms, causes, and treatment options of geriatric nose]

With increasing age, structures of the internal and external nose change. Many elderly patients complain about rhinitis with nasal obstruction, endonasal crusting, epistaxis, intermittent rhinorrhea, and olfactory disorders. These symptoms are mainly caused by atrophy of the mucosa and the olfactory epithelium, but may also be an expression of drug side effects. Additionally, there are changes in the shape of the nose (continuous growth, altered elasticity of supporting structures) and in the dermis, which may develop tumors due to its sun-exposed position. These multiple internal and external changes of the nose can be summarized by the collective term "aging nose," whose treatment options are complex. These range from conservative (nasal care, medication changes, hemostatic measures) to surgical lines of therapy (septorhinoplasty, tumor excision, vascular ligation) and will require further scientific study in the future.
