Epistaxis Severity Score (ESS) for HHT

Hoag 2010 Epistaxis Severity Score for hereditary haemorrhagic telangiectasia (HHT): six questions about typical nosebleeds over the past 3 months, normalised to 0–10. Validated in HHT only — not a triage score for acute epistaxis.

Used in: Epistaxis (Nosebleed)

Score interpretation

Minimal Epistaxis (ESS < 1) 0–0.99

ESS 0–1: no significant HHT-related nosebleeds.

→ Nasal moisturising (saline spray, emollient gel); check haemoglobin and ferritin periodically.

Mild HHT Epistaxis (ESS 1–4) 1–3.99

ESS 1–4: mild epistaxis (Cure HHT categories).

→ Nasal moisturising; check haemoglobin and ferritin and treat iron deficiency; review at an HHT centre (Second International HHT Guidelines 2020).

Moderate HHT Epistaxis (ESS 4–7) 4–6.99

ESS 4–7: moderate epistaxis.

→ As mild, plus consider oral tranexamic acid and ablative treatment (laser, radiofrequency, electrosurgery or sclerotherapy) by an ENT surgeon with HHT expertise; treat anaemia (Faughnan 2020).

Severe HHT Epistaxis (ESS ≥ 7) 7–10

ESS 7–10: severe epistaxis.

→ HHT centre: escalate — ablative therapy, systemic antiangiogenic therapy (e.g. intravenous bevacizumab), septodermoplasty or nasal closure for refractory bleeding; iron infusion or transfusion as needed (Faughnan 2020).
