Background

  • Using intraoral ultrasound can increase your success rate for identifying peritonsillar abscess
  • Ultrasound can increase your success rate for drainage over landmark method by 50%[1]
  • An alternative transcutaneous approach for identifying peritonsillar abscess is to apply a linear probe at the angle of the mandible [2]
