Deep neck infections: A retrospective study of 142 patients

Deep neck infections: A retrospective study of 142 patients. Objective: To present the symptoms, clinical courses, and management of patients with deep neck infections (DNIs) encountered in our department in 2003-2011. Methods: We reviewed the records of 142 patients diagnosed with DNIs that required hospitalization during an 8 y period. In addition, we conducted a follow-up of the patients by telephone interview. Results: The incidence of DNIs has increased significantly in our hospital since 2008. Tonsillitis (15%) and foreign bodies (11%) were the two leading causes. In 57% of the patients, the cause of DNI was not known. The most common underlying systemic disease was diabetes mellitus, noted in 21% of our patients. Branchial cleft cyst was the underlying etiology in five of the 11 patients with recurrent neck infections. Conclusion: Closer attention should be paid to DNI patients, especially to those with diabetes and hypertension. Recurrence of DNI was uncommon and suggested the existence of a branchial cleft cyst.
