Case 2
A 66 year old female patient was admitted with ”pharyngeal pain for 4 days and dyspnea for 1 day”. She had a history of type 2 diabetes for 2 years with poor control. Speciality check-up: swelling and tenderness in submaxillary and bilateral cervical areas was obvious, tenderness was positive. Emergency neck CT showed infections in retropharyngeal space, submental space and parapharyngeal space, and no large-scale abscess was found (Figure. 4A). Tracheotomy was performed under emergency local anesthesia (Figure. 4B). After the operation, anti-inflammatory, detumescence and blood glucose control were given, and the neck CT was reexamined every day. The general condition of the patient was improved day by day. Half a month later, the neck CT showed that the infection focus had disappeared (Figure. 4C), and the neck swelling was obviously improved. The tracheotomy cannula was removed (Figure. 4D), and the patient was cured and discharged.
