Abstract

Inflammation of sinuses (sinusitis) in one of the most common condition for which a patient seeks advice of a physician. In US, about 30 million patients per year visit Otorhinolaryngology clinics for sinusitis. Nasal polyposis (chronic rhinosinusitis with nasal polyp) are a subcategory of sinusitis and constitutes roughly 2-5% of patients with sinusitis. Although polyps are technically tumours, they are not malignant ones. Importance of polyps lies in the fact that nose has several vital functions in humans. First and foremost it is an entry point for air that we breath. It also processes the air, as it is an excellent humidifier. Production of mucus allows particulate trapping. It acts as a radiator that warms air. In addition to all this, it is the seat of sense of smell. Finally nose and paranasal sinuses add resonance to voice. Most common pre operative bacterial species culture was Coagulase negative staphylococcus followed by Staphylococcus aureus. Most common post operative bacterial species culture was Coagulase negative staphylococcus and Staphylococcus aureus. Coagulase negative staphylococcus were found to be resistant to ampicillin, gentamicin, cefotaxime and cephalexin. Sensitivity to ciprofloxacin and erytheromycin was found in all cases. Staphylococcus aureus was resistant to ampicillin and gentamicin only. No major difference in the antibiotic sensitivity was seen in the cultures . However resistance to the commonly used intravenous antibiotics were seen in almost all cultures whether pre operative or post operative.
