The Surgical Treatment of Peritonsillar Abscess: A Retrospective Analysis in 584 Patients

There are three surgical treatment options for patients with peritonsillar abscess (PTA): needle aspiration, incision and drainage (ID), and abscess tonsillectomy (ATE). The updated German national guideline (2015) included changes in the treatment of PTA. The indication for tonsillectomy (TE) in patients became more stringent and preference was given to ID in certain cases.

Retrospective analysis.

We performed a retrospective systematic analysis of patient data using the in-house electronic patient records and considered a 4-year period from 2014 to 2017. About 584 patients were identified. Our aim was to analyze the influence of the updated guideline on clinical practice.

236 of 584 patients (40.4%) underwent ATE with contralateral TE. In 225 patients (38.5%), unilateral ATE was performed. Mean surgery time was significantly shortened when only unilateral ATE was performed. Concerning postoperative bleeding, we noted a tendency toward a lower incidence after ATE in comparison to ATE with contralateral TE. Less than 1% of patients who underwent ATE had to be revised surgically due to postoperative hemorrhage. After the revision of the guideline, unilateral ATE and ID were conducted more frequently.

These results support that ATE in an inpatient setting is a considerably safe and effective primary therapeutic option. ID represents a favorable treatment option for patients with PTA and comorbidities, nevertheless, patient compliance is required and insufficient drainage or recurrence of PTA may occur. The revision of the guideline had a significant impact on the choice of interventions (P < .001), which is reflected by the increased number of unilateral ATE.
