BET 1: ultrasound for the diagnosis and drainage of suspected peritonsillar abscess.

A shortcut review was carried out to establish whether intraoral ultrasound increased the accuracy of diagnosis and the success of aspiration in adults with suspected peritonsillar abscess (quinsy). Using the reported searches, one paper presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of this best paper are tabulated. It is concluded that emergency physician-performed intraoral ultrasound can reliably diagnose peritonsillar abscess and leads to greater success at aspiration when compared with the traditional landmark technique.
