Minor salivary gland infection as origin of peritonsillitis - novel theory and preliminary results.

Background: Peritonsillitis (PT) is defined as cellulitis in peritonsillar tissue without pus. The pathogenesis of peritonsillar infections is controversial.

Objective: To explore whether minor salivary glands are involved in the development of PT and to identify clinical findings that predict the evolution of PT to peritonsillar abscess (PTA).
