    Introduction Tonsillectomy (TE) is one of the most common inpatient operations in Germany. A complication of this procedure is post-tonsillectomy hemorrhage (PTH). The primary aim of the study was to assess the frequency of PTH at the University Hospital Freiburg over the last six years and to identify influencing factors.

    Methods We included all TEs performed at the University Hospital Freiburg between 2014 and 2019. The following parameters were assessed: Age, sex, relevant secondary diseases and indication of TE, date of bleeding and treatment of bleeding.

    Results 1596 TEs were performed of which 1498 TEs fulfilled our inclusion criteria. All included TEs had a post-bleeding rate of 17.9 %. A higher rate of postoperative bleeding was found in the infection-free interval (n=768; 21.5 %) compared to abscess tonsillectomies (n=658; 11.7 %); without significant difference. Most of the postoperative bleeding occurred on the fifth to eighth postoperative day, with a peak on the sixth day (17.2 %). 47 % of PTH were treated conservatively, 14 % were coagulated under local anesthesia and 37 % were treated surgically under general anesthesia. Gender was the only significant influencing factor. PTH occurred significantly more frequently in male patients (20.9 %) than in female patients (15.0 %) (p < 0.01).

    Conclusions At the University Hospital Freiburg, approximately the same number of TEs are performed in an infection-free interval as abscess TEs. In contrast to the literature, a higher rate of postoperative bleeding is found in TEs in the infection-free interval. The number of surgically treated PTH, at 6,5 %, is in the range described in the literature (5-7 %). In Freiburg post-bleeding is more frequent in male patients, this result was also described by other authors.
