[Deep-neck infection: clinical analysis of 299 cases].

Deep-neck infection (DNI) remains potentially fatal. We retrospectively analyzed 299 surgically treated DNI cases between January 1997 and October 2007 by reviewing computed tomography (CT) results and discuss treatment and risk factors. Subjects were divided into two groups by abscess-site; peritonsillar abscess (PTA) (n=251) and deep-neck abscess (DNA) (n = 48). Age, smoking habits, body mass index (BMI) and bacteriological histories were collected from clinical records and compared by group. DNI and PTA severity parameters were C-reactive protein (CRP) titer and hospitalization length. Median subject age in DNI was 51.0 years and peak incidence in the 50s. Median subject age in PTA was 31.0 years and the peak incidence in the 20s. Smoker prevalence was higher in both groups than in normal healthy subjects. The DNI group had higher BMI and diabetes mellitus. Factors potentially most affecting illness were complications such as obesity and diabetes mellitus in DNI and age in PTA.
