Body<br />

Objectives:introduce a new developed technique for treatment of sialolithi<strong>as</strong>is,by using two<br />

types of energy(electrohydraulic lithotripser) while sialoendoscopy apply whitout any surgical<br />

intervention.<br />

Method and materials:sialoendoscopy is performed with patients seated or supine,using local<br />

ane<strong>as</strong>thesia for nerve and papillae(orifice dilated,can accommodate the endoscope).endoscope<br />

have two channel(working,irrigation),injected saline through irrigation channel clear the<br />

stone,concretment,mocus plug founded in sjogren syndrome and chronic parotits in children.<br />

electrohydraulic lithotripter probe inserted into working channel,1-2mm distance between<br />

stone and probe is necessary,send shock wave directly to stone,started to generate the wave at<br />

10 hz,shot number at 1,then incre<strong>as</strong>ed the voltage level and shot number at 3,stone break into<br />

small pieces while irrigating the area with saline.at the end irrigation with acrinol solution<br />

w<strong>as</strong> performed to prevent any infection.<br />

Conclusion:sialolithi<strong>as</strong>is is the most frequent re<strong>as</strong>on for salivary gland obstruction,using this<br />

newly developed sialoendoscopey system for electrohydraulic lithotripsis allow us to remove<br />

stone without any surgical intervention.<br />
