We’ve had quite a few discussions about hyoid bone syndrome, the symptoms do overlap so it’s hard to say for sure, but often strangled feelings, globus sensation & choking seem to be worse with HBS. With hyoid surgery the greater horns/ processes of the hyoid bone are shortened. It has risks the same as with a styloidectomy, but having a skilled surgeon can lessen those risks… Your hyoid bone processes look a bit longer than average maybe, (although obvs not an expert), it’s hard to say with the angle of your images, but it looks like the right side in the image with contrast could be close to the carotid sinus , which can cause cardiac arrythmias. So this could potentially cause your tachycardia, vagus nerve compression can also cause this. Here’s a couple of recent discussions about HBS, there are more if you use the search function & have plenty of time!

Who were you thinking of seeing for surgery? Not all doctors who do styloidectomies do hyoid surgery, I’m not sure of doctors in Canada, but there are several in the US; Dr Dewan at LSU has done surgeries recently, Dr Dinesh Chhetri, UCLA we believe has, Dr Cognetti in PA apparently has started doing the surgery, Dr Brad deSilva, OSU Wexner Hospital, and also Dr Marshall Smith, Salt Lake City.
