ASSESSMENT OF SURGICAL TREATMENT FOR INFECTED PREAURICULAR SINUS AT HUE CENTRAL HOSPITAL AND HUE UNIVERSITY HOSPITAL

Abstract

Background: This study aims to research clinical characteristics and to evaluate the results of early surgical treatment of infected preauricular sinus. Subjects and methods: Studied 46 patients (46 ears) sufferring from infected preauricular sinus surgically treated, by the method of descriptive observative prospective study with clinical intervention. Results: Age group of ≤ 15 years old accounted for the highest percentage with 71.8%. Combined defects accounted for 2.2%. Number of patients having familial factors accounted for 60.9%. Location of preauricular sinus: classic position 91.3%, posterior to classic position 8.7%. Positive bacteria culture with the proportion of 38.5%. Common bacterium was Staphylococcus aureus 60%. Most bacteria were sensitive to antibiotics. Stages of the infected preauricular sinus: inflammation 71.7%, abcess 48.5%. Surgical procedures: hot 69.6%, warm 30.4%. Average inpatient time: 8.5 ± 3.1 days. Recurrence after surgery 3 months having 1 ear, accounted for 2.2%. Results after surgery 3 months: good 91.3%, moderate 6.5%, bad 2.2%. Conclusions: Infected preauricular sinus were most common in children, combined defects were rare, having the role of family factors.
