Objectives:
Before the widespread use of antibiotics, most deep neck infections (DNIs) stemmed from complicated pharyngeal infections. Nowadays, they seem to be due mainly to dental infections. In 2010, our group reported that DNIs originated from a major salivary gland in 14% of cases. The main endpoint of the present investigation was to review our experience of the diagnosis and treatment of DNIs of salivary gland origin. We also compared the characteristics of DNIs originating from salivary glands with those originating elsewhere.
Methods:
Between 2000 and 2011, 44 patients were treated for DNIs of salivary origin at our institution. These patients were compared with 191 cases of DNI diagnosed as having other sites of origin.
Results/Conclusions:
In the present series, DNIs originating from a major salivary gland accounted for 19% of all cases of DNI of known origin. Patients with DNI of salivary gland origin were more likely to be elderly than those whose DNI originated from elsewhere (p=0.000). Our multivariate statistical model showed that comorbidities (p=0.051, statistical trend) and the need for surgical treatment (p=0.028) independently predicted long-term hospitalization for DNIs originating from a major salivary gland.

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
