A Clinical Analysis of Peritonsillar Abscess / 대한이비인후과학회지

ABSTRACT

BACKGROUND AND OBJECTIVES: Peritonsillar abscess (PTA) is the most common deep neck infection that occurs in adults, but until now there are so many controversies about the treatment modalities. The purpose of this study is to investigate the clinical course according to the treatment modalities for peritonsillar abscess and to evaluate the efficacy of tonsillectomy. SUBJECTS AND METHOD: Two hundred twenty-six patients with peritonsillar abscess admitted from January 1999 to October 2006. Among them, a retrospective review of medical records and additional telephone interview were performed on 151 cases. RESULTS: Among 151 cases, incision and drainage (I&D) was performed in 132 cases: 7 cases were done by aspiration and others were treated by antibiotics only. There was no significant difference in the dutarion of hospitalization between I&D, aspiration and antibiotics only (p>0.05). The incidence of recurrent PTA was only 6.6% (10/151). Tonsillectomy in PTA patients significantly reduced duration, frequency and severity of sore throat in long term follow up (p<0.05). CONCLUSION: The duration of hospitalization in PTA patients did not depend on treatment modalities. We conclude that tonsillectomy is not always necessary due to low incidence of recurrent PTA even though it improves satisfaction of PTA patients.
