Background : Deep neck infection remains a major problem for otolaryngologist as it may potentially lead to serious and fatal complications.
Objective : To assess the causes, diagnosis, bacteriology, management and complications of deep neck infections in Nan Hospital.
Material and method : A retrospective study was conducted on 127 patients with deep neck infections whom admitted in Nan Hospital between January 2008 and December 2010. Infection sites, etiological factors, bacteriology, treatment outcomes and complications were recorded and analyzed. Correlation between bacterial organisms and clinical parameters was analyzed by
logistic regression.
Results : Fifty-seven percent of the patients were male. The mean age was 41.6 ± 21.4 years (range, 1 - 84). Diabetes and thalassemia were found in 10.2% and 3.9% of the patients. The most common infection sites were submandibular space (27.6%) and buccal space (15.0%). Odontogenic infection was the most common cause (41.7%). Streptococcus viridans was the most common pathogen (15.4%), followed by Staphylococcus aureus (10.8%). The incidence of Klebsiella pneumoniae in diabetic patients was not different from non-diabetes (20% vs 7.3%, p = 0.643) but found in retropharyngeal abscess significantly higher than other spaces (50% vs 5.4%, p = 0.025). Surgical drainage was performed in 94 patients (74.0%). The major complications were upper airway obstruction (2.4%), shock (2.4%) and mediastinitis (1.6%). The death rate was 0.8%.
Conclusion : Deep neck infections in Nan Hospital were mainly caused by odontogenic infection. Infection sites, etiological factors, bacteriology, treatment outcomes and complications were corresponded with previous studies. Early diagnosis and prompted treatment were the keys of success to cope this problem.
