Abstract

Objective: Intraductal laser lithotripsy is a preferred method to fragment large, immobile intraglandular salivary stones. A number of different laser systems has been investigated for this purpose. It was our aim to study the effectiveness of a 980 nm diode laser when fragmenting salivary stones in an experimental set up. Methods: In an experimental set up we used a 980 nm diode laser for the lithotripsy of 9 salivary stones. The temperature circle around the laser fibre tip was measured and stone remnants were chemically analysed for their composition. Results: The salivary stones had a mean diameter of 6.7 mm x 5.6 mm x 3.0 mm. Laser fragmentation with the diode laser was successful at all stones. The temperature next to the salivary stone increased to around 30 degrees C during the active lithotripsy with continuous rinsing (fluid temperature 21 degrees C). At a distance of 2 mm the temperature around the laser fibre's tip is reduced by already about 50%. The salivary stones mainly consisted of carbonate apatite, followed by beta-calcium phosphate and other calcium phosphates. Conclusion: The fragmentation of salivary stones with a 980 nm diode laser is possible in principle. Under a continuous irrigation with a positioning of the laser fibre's tip at the centre of the stone, no relevant temperature increase in the vicinity of the stone occurs. However, before the laser is used in humans, in vivo experiments on animal material seem to be advisable. (C) 2013 Elsevier Ireland Ltd. All rights reserved.
