Abstract
SUMMARY
This study recruited 30 patients with chronic rhinosinusitis undergoing bilateral functional endoscopic sinus surgery and randomized to have absorbable nasal dressing impregnated with trimicinolone (2 mL of a 40-mg/mL) in one nostril and absorbable nasal dressing impregnated with saline in the other side. Recurrent cases were excluded.
Postoperative healing assessments of edema, crusting, secretions, and scarring were done at postoperative days 7, 14, 28 and at 3 and 6 months using validated Lund-Kennedy and POSE scores. Patients were all to resume their nasal saline irrigation and intranasal steroid sprays postoperatively per routine. Baseline Lund-Mckay, Perioperative Sinus Endoscopy (POSE), and Lund-Kennedy scores were collected.
Results showed that POSE and Lund Kennedy score became significantly lower beginning from day 7 till month 6. POSE and Lund Kennedy score significantly decreased in medicated and non-medicated sides beginning from day 7 till 6 months (P ≤ 0.05). A statistical significant difference were found between medicated and non-medicated throughout the 6 month follow up (P ≤ 0.001) which reveals the adding beneficial effect of local steroids on post-operative chronic sinusitis patients.
Compared to other studies, the current study used local steroids (triamcinolone) with self-control and not proceeded by systemic steroids.
