La sinusitis es la inflamación de las cavidades sinusales que son espacios húmedos y huecos en los huesos del cráneo. Hay cuatro pares de senos:

  • Senos frontales
  • Senos maxilares
  • Senos etmoides
  • Senos esfenoides (no se muestran en la ilustración)

Si la abertura de la cavidad sinusal se tapona, el flujo de moco se bloquea y la presión crece lo que causa dolor e inflamación.
