What we assess
- Chronic rhinosinusitis
- Nasal polyps
- Functional Endoscopic Sinus Surgery (FESS)
- Pre- and postoperative care
Assessment and care
- Review symptoms, nasal endoscopy and CT when indicated
- Confirm an adequate course of medical treatment first
- Discuss benefits, risks, alternatives and follow-up
When is a CT scan needed for sinus problems?
A CT scan is usually unnecessary for a short-lived cold or uncomplicated acute sinus symptoms. Non-contrast CT may be considered for symptoms lasting over twelve weeks, disease that persists despite appropriate treatment, nasal polyps, suspected complications or planning sinus surgery. Findings must be interpreted alongside symptoms and nasal endoscopy; an abnormal scan alone does not mean surgery is required.
When to consider it
Chronic symptoms, treatment failure, polyps, unusual one-sided disease, suspected complications or surgical planning.
Assessment
History, nasal examination, endoscopy and selected CT findings are interpreted together.
Treatment options
Saline irrigation, intranasal steroids, cause-directed care and selected FESS may be considered.
When it is urgent
Eye swelling, reduced vision, confusion, neck stiffness or a severe new headache needs emergency care.
Frequently asked questions
What is FESS?+
Functional Endoscopic Sinus Surgery uses an endoscope through the nose to open sinus drainage pathways, usually without an external incision.
When is sinus surgery needed?+
It may be considered for selected chronic sinusitis or polyps that persist despite appropriate medical treatment and are supported by endoscopy/CT findings.
Why is follow-up important after sinus surgery?+
Follow-up checks healing, removes crust when needed, detects infection or bleeding and supports correct saline and nasal-medication use.
