Background:
Deep neck infections (DNIs) are potentially life-threatening diseases that are mainly caused by odontogenic and peritonsillar infections. Although DNI has also been reported to be caused by foreign bodies, no review articles exist to date.
Methods:
A comprehensive literature search was conducted using PubMed for articles published between 2005 and 2025.
Results:
A total of 131 relevant articles were identified. Frequently reported foreign bodies included injectable materials used in facial filler and fish bone. The latency to symptom onset varied widely, ranging from within 1 h after foreign body insertion to as long as 25 years, with substantial differences observed depending on the type of foreign body.
Conclusion:
Although foreign bodies are rare causes of DNIs, various type of foreign bodies have been reported. Recognizing the possibilities of DNIs caused by foreign bodies will help oral and maxillofacial surgeons to search for the cause rapidly and determine treatment plans and prevent recurrence.
