Abstract
Introduction: Acute otitis externa is a common condition involving inflammation of the ear canal. The acute form is caused primarily by bacterial infection, with Pseudomonas aeruginosa and Staphylococcus aureus the most common pathogens. Acute otitis externa presents with the rapid onset of ear canal inflammation, resulting in otalgia, itching, canal edema, canal erythema, and otorrhea, and often occurs following swimming or minor trauma from inappropriate cleaning. Tenderness with movement of the tragus or pinna is a classic finding. Neomycin/polymyxin B/hydrocortisone preparations are a reasonable first-line therapy when the tympanic membrane is intact. Oral antibiotics are reserved for cases in which the infection has spread beyond the ear canal or in patients at risk of a rapidly progressing infection.
Aim: To compare the efficacy of polymyxin B, Neomycin and Polymyxin B, Neomycin, Hydrocortisone in the treatment of Otitis externa.
Methodology: This study was carried out in the Department of ENT, Nepal Medical College Teaching Hospital (NMCTH), Attarkhel, Kathmandu, Nepal from August 2012 to May 2014. This, prospective randomized study included patients with otitis externa. Patients of all age groups and both gender were included in this study. Patients were randomized into two groups; Group A: Patients, who received Polymyxin B, Neomycin and Group B patients, who received Polymyxin B, Neomycin, Hydrocortisone. Pack soaked either with polymyxin B neomycin/ hydrocortisone and applied for 48 hours. If not recover again applied for next 48 hours. The study will be conducted on the patient diagnosis, clinical features- signs: 1. Tragal tenderness. 2. Circumduction tenderness. Thus, the efficacy was compared between two drug groups.
