Summary
Endoscopic removal of submandibular stones is a safe and effective treatment. This sialoendoscopy technique reduces missed stones and nerve injury compared to traditional methods.
Area of Science:
- Otolaryngology
- Minimally Invasive Surgery
Background:
- Submandibular stones are commonly treated with transoral removal or sialoadenectomy.
- These traditional methods carry risks of missed stones and nerve injury.
Purpose of the Study:
- To evaluate the efficacy and safety of endoscopic removal for submandibular stones.
- To minimize complications associated with traditional stone removal techniques.
Main Methods:
- Retrospective study of 13 patients undergoing endoscopic submandibular stone removal.
- Procedures performed under general anesthesia using carbon dioxide laser and a 3.1-mm rigid scope.
- Stones were fragmented with laser or removed with specialized instruments.
Main Results:
- Successful stone removal in 11 out of 13 patients (84.6%).
- Complete symptom resolution in 11 patients within 4 weeks.
- No instances of lingual or hypoglossal nerve injury were reported.
Conclusions:
- Sialoendoscopy is a safe and effective treatment for submandibular ductal stones.
- This endoscopic approach reduces missed stones and nerve damage.
- It also decreases the necessity for sialoadenectomy.
