Notizen: Summary Standardized operations including incisions and ablations were carried out on pigthroats immediately prior to evaluation of the depths of thermal damage zones measured with a unit of 30 mikrons. The following parameters were applied on the tissue: 1) Continuous versus single pulse mode. 2) equal energy impacts with variation of time and power density. 3) super pulse versus non super pulse. In the 1st series the tissue damage for all tissues examined were significantly lower in the single pulse mode than in the continuous mode. In the 2nd series the pooled material showed a significance in favour of short impacts with high power density although the total energy required for a single operation was up to 40% higher in the high power/short time series. The 3rd series showed no significance in differences between super pulse and nonsuper pulse damage when applying the same average output on the laryngeal tissues involved.
