Table 1 Recommended planning timeframes for various rhinologic surgeries during the COVID-19 era

From: CSO (Canadian Society of Otolaryngology - Head & Neck Surgery) position paper on rhinologic and skull base surgery during the COVID-19 pandemic

Priority (Suggested Timeframe) Surgical Procedure
Emergent (<  24 h) - Lesion or disease process (e.g. mucocele, infection, inflammatory, neoplastic, bleed) with significant acute neurologic or ophthalmologic compromise
- Invasive fungal sinusitis
- Significant bleeding that cannot be managed by other means (e.g. packing, medical, interventional radiology)
Urgent (<  1 week) - CSF leak repair (traumatic, iatrogenic)
- Control of recurrent significant epistaxis (e.g. SPA ligation after failed nasal packing)
- Severely displaced or open fracture
Semi-Urgent (<  4 weeks) - Biopsy of concerning nasal mass
- Malignant sinonasal/skull base skull tumour resection
Expedited (<  3 months) - Benign nasal tumour (ex. Juvenile nasopharyngeal angiofibroma, hemangioma, inverting papilloma)
- Mycetoma
- Odontogenic sinusitis
- CSF leak repair (spontaneous)
Standard (Regular Waitlist) - Endoscopic sinus surgery for CRS or mucocele (without neurologic or ophthalmologic compromise)
- Other rhinologic procedures (e.g. septoplasty, septorhinoplasty, dacrocystorhinostomy, orbital decompression, functional nasal surgery)
- Skull base or orbital procedures for benign disease without neurologic compromise
