Bilateral peritonsillar abscesses.

In the discussion about the management of the peritonsillar abscess (PTA) in regard to the pros and cons of tonsillectomy à chaud versus à froid, the risk of obscure contralateral abscesses is often neglected. To the authors' knowledge, there are only a few series of PTA being analyzed for the abscess rate of bilateral PTA. A group of 541 abscess tonsillectomies was retrospectively analyzed for the presence of a bilateral manifestation of peritonsillar abscess. Twenty-one patients (3.88%) had bilateral abscesses. None of these had been detected prior to the operation. Of the 541 patients, 2.22% had postoperative hemorrhages that had to be arrested under general anesthesia. Within the discussion about abscess tonsillectomy versus stab incision followed by interval tonsillectomy (à froid), the rate of almost 4% bilateral abscesses should be taken into consideration as dangerous complications such as mediastinitis could develop from the remaining abscess formation of the contralateral side.
