Hereditary hemorrhagic telangiectasia – A perennial disease?

Introduction Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disease that leads to vascular malformations and thus presents epistaxis as the main symptom. The bleedings occur after vascular ruptures in the nasal mucosa and can take on a wide variety of forms. The severity is recorded using the so-called epistaxis/nosebleed severity score (ESS/NSS). The intensity of epistaxis can differ significantly from that of "normal" epistaxis. An investigation was therefore carried out regarding seasonal parallels.
