Your surgeon will try to make things people proof to achieve the best results. I didn't go to Dr. Haben myself, I went with Dr. Spiegel, but they cinch those stitches in pretty good. Well enough to withstand some light coughing for sure. For the record, I coughed a lot when my dissolvable stitches poked into my throat during recovery. I emailed my surgeon and he said to not worry about it, and that the stitches he put in there won't break. He also said that he expects these things to happen, and that he makes sure they will hold up. Don't worry about a little coughing. Dr. Spiegel also mentioned that you will know if your stitches pop because it will be very noticeable. I hope this helps put your mind at ease during your recovery! For the record, my voice turned out beautifully. All the best during your healing. It is totally worth the wait!!! ☺
