INTRODUCTION: This study aims to investigate the efficacy of holmium: yttrium aluminum garnet (Ho: YAG) laser as an intracorporeal lithotripter in the treatment of salivary calculi during sialendoscopy and to evaluate procedure-related complications.
METHODS: Between April 2014 and April 2016, a total of 31 patients (22 males, 9 females; mean age 38 years; range, 8 to 57 years) who were treated with laser sialendoscopy were included. The patients were postoperatively followed on a weekly basis for four weeks and every month, thereafter. Procedural success was defined as the absence of symptoms after a three-month follow-up.
RESULTS: Calculi were located in the parotid gland in eight of the patients and in the submandibular gland in 23 patients. The dimension of calculi varied between 2 to 12 mm. A 1.6 mm-Marchal all-in-one scope was used during sialendoscopy and the Sphinx 30, Lisa Laser was used as the laser device. In 27 of the patients, calculi were completely removed using laser sialendoscopy. In one of these cases, a second session was needed, since the patient definitely refused gland excision. In the second session, calculi were removed after breaking with laser lithotripsy. In four of these cases, calculi breaking process was unable to be completed with laser lithotripsy and open surgery was carried out. There was no canal perforation or nerve damage in any of the patients.
DISCUSSION AND CONCLUSION: Based on our study results, Ho: YAG lasertripsy is an effective and safe method in the treatment of salivary calculi. The use of Ho: YAG laser as an intracorporeal lithotripter increases the treatment success rate of salivary calculi with sialendoscopy.
