Summary
Sialography is generally safe, with minor pain and swelling typically resolving within one day. Some patients experienced reduced pain below baseline levels two days post-procedure, suggesting a potential benefit.
Area of Science:
- Radiology
- Salivary Gland Imaging
Background:
- Sialography is an imaging technique used to visualize salivary glands.
- Post-procedural pain and swelling are potential side effects that require quantification.
Purpose of the Study:
- To investigate the incidence and severity of pain and swelling following sialography.
- To quantify the duration of these post-sialography symptoms.
Main Methods:
- 92 patients underwent sialography and completed questionnaires assessing pain and swelling using a Visual Analogue Scale (VAS).
- Friedman repeated measures analysis of variance on ranks was used for statistical comparison.
Main Results:
- VAS scores for pain and swelling significantly increased 1 hour post-sialography.
- Swelling returned to baseline within 1 day, while pain also decreased significantly below baseline by 2 days post-procedure.
Conclusions:
- Sialography is a safe diagnostic procedure.
- Minor post-procedural effects like pain and swelling usually resolve within 24 hours.
- A notable reduction in pain below baseline levels by day two suggests a possible analgesic effect of sialography.
