FIVE KEY-POINTS
  1. The 3 centers managed surgically 537 patients in 2019, versus 87 in 2020.  This represents a global 84% decrease in terms of surgical volume.
  2. The ratios calculated for other surgeries in other affected regions in the world are similar
  3. The number of cervicotomies for cancer remained stable
  4. The decreased volume is essentially at the expense of functional surgery
  5. The number of scheduled tracheostomies increased from 8 to 22.
