Tonsillar origin of deep neck infection as a negative prognostic factor for developing complications.

<b>Aim:</b> The aim of this study was to compare the odontogenic and tonsillar origins of deep neck infection (DNI) as a negative prognostic factor for developing complications. </br></br> <b>Methods:</b> This was a retrospective study of 544 patients with tonsillar and odontogenic origins of DNI treated between 2006 and 2015 at 6 ENT Departments and Departments of Oral and Maxillofacial Surgery. Complications from DNI (descending mediastinitis, sepsis, thrombosis of the internal jugular vein, pneumonia, and pleuritis) were evaluated in both groups and compared. Associated comorbidities (cardiovascular involvement, hepatopathy, diabetes mellitus respiratory involvement, gastroduodenal involvement) were reviewed. </br></br> <b>Results:</b> Five hundred and forty-four patients were analyzed; 350/544 males (64.3%) and 19/544 females (35.7%). There were 505/544 cases (92.8%) with an odontogenic origin and 39/544 cases (7.2%) with a tonsillar origin of DNI. Complications occurred more frequently in the group with tonsillar origin of DNI (P < 0.001). There was no difference in diabetes mellitus between the two groups. </br></br> <b>Conclusions:</b> Currently, the tonsillar origin of DNI occurs much less frequently; nevertheless, it carries a much higher risk of developing complications than cases with an odontogenic origin. We recommend that these potentially high-risk patients with a tonsillar origin of deep neck infections should be more closely monitored.

Severe parapharyngeal abscess that developed significant complications: management during the COVID-19 pandemic.

A 50-year-old Caucasian man presented to the emergency department during the early stages of the COVID-19 pandemic with a rapidly progressive facial swelling, fever, malaise and myalgia. The patient had recently travelled to a COVID-19-prevalent European country and was therefore treated as COVID-19 suspect. The day before, the patient sustained a burn to his left forearm after falling unconscious next to a radiator. A CT neck and thorax showed a parapharyngeal abscess, which was surgically drained, and the patient was discharged following an intensive care admission. He then developed mediastinitis 3 weeks post-discharge which required readmission and transfer to a cardiothoracic unit for surgical drainage. This report discusses the evolution of a deep neck space infection into a mediastinitis, a rare and life-threatening complication, despite early surgical drainage. This report also highlights the difficulties faced with managing patients during the COVID-19 pandemic.
