ENT & Otolaryngology Clinical Calculators
Otolaryngology—Head and Neck Surgery requires precise diagnostic differentiation, whether distinguishing peripheral from central vertigo or determining the surgical necessity of a pediatric tonsillectomy. The MedCalc ENT Hub provides rapid, 100% offline access to the specialty’s most heavily utilized clinical criteria and quality-of-life indices.
From staging chronic rhinosinusitis using the Lund-Mackay CT system to executing the HINTS exam for acute vestibular syndrome, these tools eliminate cognitive overload in high-volume clinics. All algorithms and questionnaires are strictly aligned with current clinical practice guidelines from the American Academy of Otolaryngology–Head and Neck Surgery (AAO-HNS).
