Methods: Thirty-nine patients with a clinical diagnosis of peritonsillar infection, 24 females and 15 males (age range, 7 to 44 years), were evaluated in the Clinical Hospital of Sao Paulo University Medical School, in the Otolaryngology Emergency Service. These patients were evaluated with intraoral and percutaneous ultrasound. Needle aspiration was used to compare and confirm the diagnosis. Results: The ultrasound showed 69.3% of the patients with peritonsillar abscess and 30.7% with peritonsillar cellulitis. The sensitivity was 96% and the specificity was 78.5%. Conclusion: The authors conclude that ultrasonography performed by a experienced radiologist proved to be a efficient method in the differential diagnosis of peritonsillar abscess and peritonsillar cellulitis.

This practice is widespread despite the lack of evidence to support its efficacy in the literature. Thirty patients undergoing septoplasty were randomised into two groups-one in whom infiltration was performed with lignocaine (2%) with adrenaline (1:80,000) and a control group who received lignocaine (2%). Both groups of patients received intranasal application of cocaine paste prior to surgery. The surgeon and anaesthetist were blinded to the contents of the infiltration. The operative field was rated by the surgeon, and the blood loss calculated. No significant difference was demonstrated in blood loss or surgical field between the groups. However there was significant rise in systolic blood pressure in patients who received epinephrine. The use of epinephrine with cocaine paste does not improve haemostasis or surgical field. As the use of epinephrine is associated with cardiac arrhythmias, the authors suggest that combined use of cocaine paste and epinephrine infiltration should be avoided in septal surgery.
