I. Domestic criteria for assessing the efficacy of chronic sinusitis
Phase I healing: 3 months postoperative intra-sinus epithelialization
Delayed healing: post-operative intraoperative cavity re-existing granulation or polyps, intra-sinus epithelialization after treatment (4~5 months)
Delayed inflammation: Continued infection in the sinus cavity after surgery, polyps or granulation still present after multiple treatments for more than 6 months
No change: prolonged inflammation persists for 1 year, or a second surgery is needed in a short period of time (3 months)
II. Foreign standards
(1) Schaitkin,1993
Symptoms after surgery, follow-up for more than 3 years
I: Symptoms disappeared
II: disappearance of symptoms after retreatment
A Internal medicine treatment
B revision surgery
III: Improvement of main symptoms (no need for further treatment)
IV：Major symptom improvement (need further treatment)
A Internal treatment
B Revision surgery
The above is a successful surgery;
V: Main symptoms remain or worsen (further treatment is still not effective)
V: Failure of surgery
VI: Loss to follow-up
(2) Terris, 1994
Subjective symptoms.
Very good: complete disappearance of symptoms
Good: symptoms improved, not all disappeared, patient had 2-5 sinusitis episodes per year, good response to medical treatment
Poor: symptoms did not disappear after surgery, or symptoms worsened.
III. Objective assessment method
Sometimes the patient’s subjective symptoms are not consistent with the clinical examination results. The author has applied CT scan after nasal endoscopy to evaluate the efficacy of clinical endoscopic surgery.
