Primary Outcome Measures
NameTimeMethod
<p>Peak fluorescence (F), time to peak fluorescence (T) and time to half-peak<br /><br>fluorescence (T1/2) will be measured. As a reference point we will measure the<br /><br>peak fluorescence of normal mucosa of the pharynx. Perfusion data will be<br /><br>correlated with the development of PCF or wound healing problems within 4 weeks<br /><br>after surgery. A receiver operation curve will be computed to determine<br /><br>sensitivity and specificity of ICG-IOLA. We will determine cut off values for<br /><br>hypoperfusion by relating the development of wound healing problems or PCF<br /><br>within 4 weeks of surgery to each variable. </p><br>
Secondary Outcome Measures
NameTimeMethod
<p>We want to compare perfusion rate of PTL to perfusion rate in STL in order to<br /><br>create cut off values for both patient categories.</p><br>
