Powered Air-Purifying Respirator (PAPR)

PAPRs are reusable respirators that are typically loose-fitting hooded or helmeted. They are equipped with a battery-powered blower to force air through a particle filter for the wearer to breath. They are capable of reducing airborne exposures at efficiencies that typically exceed the N95 and EHFR, using a high-efficiency particulate air filter (information from the Department of Health and Human Services, Centre for Disease Control and Prevention, United States).

  • Recommendations from the OHNS Department at University Health Network led by Ralph Gilbert in Toronto for head & neck oncologic procedures:  (1)  All procedures that include any instrumentation of the upper airway including the oral cavity and nasopharynx should be treated as high risk procedures and all staff in the operating room should be protected with PPE –  For nursing and surgical staff this includes N95 masks, eye protection, gowns and gloves.  Surgical staff may use loops if required for the surgical procedure.  (2)  All other procedures should be managed as per operating room standard.  (3)  Where possible we should work to minimize the number staff in the room during the aforementioned procedures, this includes residents and fellows who are not required for performance of the surgical procedure.  (4)  All patients that are scheduled for surgical procedures of the upper airway including the oral cavity will undergo COVID-19 screening 48hrs prior to the planned surgical procedure, should they test positive, their procedures will be deferred until screened negative.  (5)  COVID-19 screening can take place at a regional COVID-19 testing centre closest to the patient. (6)  For high risk procedures as defined above; the department recommends that oral cavity and nasal sites be separated from the remainder of the surgical sites for procedures such as neck dissection and parotidectomy. Techniques include the application of adhesive and sterile drapes.


  • Endocrine Surgery during the Covid-19 pandemic

The AHNS Endocrine Surgery Section  felt that it might be useful to have some guidance on endocrine  surgery cancellation given the Covid-19 pandemic. These are loosely adapted to those of the ESES.  These are just suggestions as to which patients may need to move forward with surgery now. The specific decisions would be in the context of local hospital and community resources, directives and importantly surgeon judgment.  The duration of postponement is not currently widely agreed upon.  Also with any patient being brought to the OR now or in the future given spread possible from intubation of asymptomatic  Covid -19 patients  all patients should be considered for COVID-19 testing


  • Life-threatening  or severely symptomatic Graves’ that cannot be controlled medically
  • Goiter causing airway compromise with airway symptoms and tracheal narrowing
  • Thyroid cancers that are imminently threatening the life or the health of the patient such as those with short double timings or aggressive recurrences.
  • Open biopsy to confirm a suspected diagnosis of anaplastic thyroid cancer or thyroid lymphoma in order to direct appropriate treatment.


  • HPT with life-threatening hypercalcemia that cannot be controlled medically
