    Abstract:
    INTRODUCTION: Peritonsillar infection is the most frequent complication of acute tonsillitis. Peritonsillar infections are collections of purulent material, usually located between the tonsillar capsule and the superior constrictor of the pharynx. Peritonsillar infection can be divided into abscess and cellulitis. MATERIAL AND METHODS: We prospectively analysed the clinical data from 100 patients with peritonsillar infection from 2008 to 2010. The diagnosis of abscess or peritonsillar cellulitis was primarily based on obtaining pus through fine-needle aspiration. RESULTS: Seventy-seven per cent of patients had no history of recurrent tonsillitis and 55% were receiving antibiotic treatment. Sixty-two cases were peritonsillar abscess and the rest were cellulitis. Trismus, uvular deviation and anterior pillar bulging were statistically associated with peritonsillar abscess (P<.005). All patients were admitted to hospital and treated with puncture-drainage, intravenous antibiotics (amoxicillin/clavulanate in 83% of cases) and a single dose of steroids. All patients were discharged on oral antibiotic therapy. The mean length of hospital stay was 3 days and the recurrence rate was 5%. CONCLUSIONS: Due to the absence of clinical practice guidelines, there are different therapeutic protocols. According to our experience, puncture-aspiration and administration of intravenous antibiotics is a safe, effective way to treat these patients. To determine the efficacy and safety of outpatient management, controlled studies would be needed.
