Abstract
Purpose
We wanted to compare the CT findings and clinical features of parotitis and submandibular sialadenitis in children and adults and to evaluate the statistical significance of these in different age groups and the usefulness of a CT scan.
Materials and Methods
Ninety-seven adults and 36 pediatric patients with sialadenitis were included in this retrospective study. Regardless of the site of involvement, we evaluated the CT findings and clinical manifestations between the pediatric and adult groups, and between the pediatric and adult parotitis and submandibular sialadenitis groups. At last, all the patients were classified into seven age groups.
Results
Abscess formations were more prominent in the parotitis groups, and sialiths were more common in the submandibular sialadenitis group with the lowest incidence in the young children group (≤ 10 years). Cellulitis seen on a CT scan showed a higher incidence in the adult parotitis group, and this finding was closely connected with pain. A number of patients showed cervical lymphadenitis on a CT scan and this coincided with lymph node palpation. Tonsillitis associated sialadenitis was common in the pediatric group. The therapeutic durations were longer in the pediatric parotitis patient group and the adult submandibular sialadenitis group.
