Pre-operative assessment:
Complete blood counts, Absolute Eosinophil Count (AEC), and total Serum Immunoglobulin (IgE) levels were assessed, along with a Quality-of-life questionnaire-Sino- nasal Outcome Test (SNOT- 20). The standard reference level of serum IgE in our institute was 0-100 IU/ml, and in AFRS, as per standard,>500 IU/ml was considered elevated. The standard reference range for AEC in our Institute was 40 -440 mm3. In AFRS, as per standard, a value of more than 500mm3 was considered elevated. Nasal polyps were graded by endoscopy according to Kupferberg’s grading system.7Patients were given a course of antibiotics (Roxithromycin 150 mg twice a day for ten days) and a short course of oral steroid (8 mg Methylprednisolone for five days followed by 4 mg methylprednisolone for five days) one week prior to endoscopic sinus surgery.
