As an M3 I did an above-knee amputation skin to skin. That was pretty neat. I also did a chest tube on tension pneumothorax as an M4, and popping into the pleura and hearing that "PSSSHHHHH" was incredibly satisfying.
In residency, we do plenty of crazy **** on ENT. Our service usually does the fun transfacial part of skull base resections
@neusu mentioned, but those are pretty rare since we have an aggressive endoscopic skull base surgeon who will do pretty much anything endoscopically.
Personally, my favorite case was a
radical maxillectomy last month (orbital extenteration, total maxillectomy, external ethmoidectomy and sphenoidotomy) with a really tough neck dissection (retropharyngeal nodes). I also enjoy robotic surgery a ton.
