Yes, that glue that Remarcle uses seems to be uncomfortable for some. At some point it will come loose and come out with a cough. It is probably his way to ensure the suture stays tight even though it is a dissolving suture. Dr Kim uses permanent sutures to achieve this. Some patients of Dr Haben who apparently does not use either have reported thair stitches coming loose, I believe? (Correct me if I am wrong).
Ritana - the praat pitch reading depends on a lot of things first of all, if you measure "artefacts", it can distort the average pitch. So if you notive parts of the recording (let praat show the blue pitch line) that are below 120 Hz or above 500 Hz, most likely those are artefacts, unless they are really clearly part of that line. You should not mark that part then for pitch measurement, but choose a different part. You can also just check parts of the recording - just 5 second pieces and see if the pitch varies between them.
Another thing is that average pitch depends a LOT on voice melody and thus on your mood. If I am in a particularly good mood and use a lot of higher pitched parts as part of my voice melody, the average can be 40 or 50 Hz higher than if I am speaking rather monotonously. So if you want to compare, use the same voice melody and pitch range for recordings.
And lastly of course pitch is not stable from day to day or morning to evening. My pitch seems to be lower and more hoarse in the morning then get better over the day and then lower again in the evening with more vocal fry in it...
Speaking of vocal fry - using it (unintentionally mostly) can cause a much lower pitch reading.
