摘要

Background

Management of parotid duct sialolithiasis is complicated by the anatomical intricacy of Stenson’s duct. Obstruction leads to recurrent pain, preauricular swelling, and secondary infection. Postoperative stenting is essential to preserve ductal patency and minimize the risk of restenosis. However, conventional stents such as silicone or PTFE (lacrimal tubing) may be costly or unavailable in resource-limited settings. This technical note explores the use of a widely accessible and cost-effective alternative: an 18-gauge intravenous (IV) cannula as a temporary ductal stent.

Method

Patient with anteriorly located parotid duct stone—anterior to the masseter muscle—underwent intraoral ductal exploration and stone retrieval. Following stone removal, an 18-gauge IV cannula was carefully inserted into the duct to function as a temporary stent. The cannula was trimmed for optimal fit, secured in place, and was retained for 2 weeks. Patient was assessed for pain, swelling, stent tolerance, salivary output, and any adverse events.

We observed that the IV cannula stent was well tolerated, with no instances of infection or ductal stricture. Patient experienced restoration of salivary flow and resolution of preoperative symptoms. The technique demonstrated reliable efficacy and excellent patient tolerance.

Conclusion

The use of an 18-gauge IV cannula as a temporary parotid duct stent offers a viable, safe, and economical alternative to commercial stents. This method is particularly advantageous in low-resource settings and can be adopted as a pragmatic solution where conventional materials are inaccessible. However, being a single case report, further research is required to recommend it as an effective clinical measure in every case.
