Ultrasound-Guided Sialendoscopy Surgery for Parotid Sialolithiasis Using Yttrium Aluminum Garnet (YAG)-Holmium Laser: A Prospective Case Series.

BACKGROUND

Parotid sialolithiasis is a common condition in middle-aged individuals, with most cases occurring in the submandibular and sublingual glands, followed by the parotid glands and minor salivary glands. The treatment of salivary gland stones, particularly those of the parotid glands, remains challenging. Endoscopic surgery using a yttrium aluminum garnet (YAG)-holmium laser for parotid sialolithiasis is a minimally invasive approach that provides effective treatment for patients. This study aimed to evaluate the outcomes of the endoscopic laser treatment of parotid sialolithiasis a YAG-holmium laser.

MATERIALS AND

METHODS

A prospective case series study was conducted on 21 patients diagnosed with salivary gland stones in the parotid gland based on clinical features and imaging findings (including ultrasound and computed tomography scans), from March 2022 to March 2024. These patients underwent sialendoscopy surgery using a YAG-holmium laser and were evaluated for surgical results at 2, 4, and 12 weeks.

RESULTS

Cases with completely reduced symptoms accounted for 90.5%, whereas cases with partially reduced symptoms accounted for 9.5%. The ultrasound image of the salivary gland after surgery was significantly improved compared to that before surgery. After three months of surgery, most patients (90.5%) were satisfied. The postoperative complication rate was 14.3%, which included scarring at the opening of the salivary gland and in the salivary duct.

CONCLUSION

Sialendoscopic surgery using a YAG-holmium laser for parotid sialolithiasis is a minimally invasive surgical intervention that leaves no scarring, reduces the risk of complications as seen in open surgery, and shortens the postoperative care time for patients.
