Peritonsillar abscess or cellulitis? A clinical comparative paediatric study.

OBJECTIVE

Peritonsillar sepsis (PTS) can be divided into abscess and cellulitis. It is the most common deep neck infection in the paediatric age group. In this article we discuss the clinical issues related to peritonsillar sepsis in children.

METHOD

This study involves 185 cases of peritonsillar that were treated at the Montreal Children's Hospital in the last 10 years. The symptoms, signs, laboratory and radiological data as well as the medical and surgical therapies are included.

RESULTS

Seventy-five cases were peritonsillar cellulitis (PTC) and the rest were abscesses. The age at presentation varied between 2.5 months and 18 years. The majority of the cases diagnosed as peritonsillar abscess (PTA) occurred from age 12 to 18 years. Trismus was the only complaint that was statistically associated with PTA. Uvular deviation combined with trismus was also important in differentiating PTA from PTC. Our data revealed a lower percentage of anaerobic bacteria and the majority of cultures grew Streptococcus pyogenes group A.

CONCLUSIONS

Clinical picture is important in differentiating PTA from PTC. Recurrence of peritonsillar sepsis was higher in children with a history of recurrent tonsillitis. Needle aspiration of PTA resulted in a higher incidence of recurrence compared to incision and drainage. A management algorithm is suggested for the child presenting with peritonsillar sepsis.
