Paper Abstract

We sought to study the effect of fiber tip modification on the size and shape of lesions created by the interstitial application of a 805 nm diode laser. In order to clarify conflicting results of other authors, we performed a large number of burns in order to obtain definitive statistically significant data. The plastic cladding and jacket were removed from the distal 5 mm of a hard polymer clad fused silica fiber of 600 micrometers . Three tip modifications were compared: a bare cut tip with and without precharring and a conical diffused tip. Continuous wave laser radiation was applied over a 1.0 to 2.5 watt range at 0.5 watt increments for a duration of 5, 10, and 15 minutes in vitro using fresh pig liver. The liver burns were thinly cut in cross-sections, and photographed. The sizes of the resultant cavity and lesion were measured and analyzed for statistical significance.
