Diagnostic digital infusion submandibular sialography offers significant therapeutic benefits, improving symptoms in 67% of patients. This procedure involves minimal radiation exposure, making it an effective treatment option for salivary gland issues.
Area of Science:
- Radiology
- Salivary Gland Imaging
- Minimally Invasive Procedures
Background:
- Sialography, combining ductal dilation and hydrodilation with antimicrobial contrast, is used for diagnosis.
- The therapeutic potential of sialography remains under-investigated in large contemporary studies.
Purpose of the Study:
- To evaluate the therapeutic value of diagnostic digital infusion submandibular sialography.
- To assess symptomatic response following the procedure.
Main Methods:
- Retrospective review of 135 consecutive submandibular sialograms (April 2008 - November 2024).
- Focus on symptomatic response in 67 patients with available follow-up data.
- Analysis of indications, symptom improvement rates, and correlation with radiographic findings.
Main Results:
- Symptomatic improvement was observed in 67% of patients (45/67).
- Complete symptom relief rarely required further treatment (15%).
- Distal strictures were associated with higher improvement rates (78% vs. 57%).
- Radiation dose for sialography (0.14 mSv) was significantly lower than preceding CT (1.94 mSv).
Conclusions:
- Diagnostic submandibular sialography demonstrates significant therapeutic efficacy.
- The procedure is associated with limited radiation exposure.
- Further prospective studies are warranted to fully elucidate its therapeutic impact.
