It's extremely unclear, as to what counts as major or minor. Where do you draw the line?
I haven't the faintest clue, as to whether what I've had, would be considered major, only minor, or is kinda in a grey zone, in terms of this poll.

Officially, major surgery is when they have to operate in the head (brain and spine, not dental) or torso, since that's where all the stuff that keeps you alive is located. If they had to cut open your leg or remove it, while the surgery is a big deal, it's technically a minor surgery.

An appendix is major surgery, even though in countries with adequate health care it's a fast and relatively minor ordeal if it's removed before it bursts. If it bursts then it's a race to save your life.

Edit: I'm actually happy to see only a small percentage of people having major surgery, because that means most people aren't facing issues that need fixing on that level.

Had couple of minor surgeries... One for screw in my broken elbow, and one to remove infection in my gums (not teeth but like they cut open the gums)

I've had both one major and one minor surgery. Major was not so pleasant (the aftereffects anyway), don't really want to repeat that. Minor one wasn't a problem. I also had LASIK surgery, don't know if that counts, too.

I had eye surgery and teeth surgery

Minor surgery at, I think, 15. It's not a tumor.meme. Except it was.

had full anaesthetic/hospitalization dental surgery as a child
I was considering cosmetic surgery; but weightlifting exceeded my expectations
so I'll save that for later.

Not sure what this counts as, but when I was a kid, I once smashed my head against a glass coffee table, had to be rushed to the hospital, and ended up with 16 stitches on my forehead.

I've also had wisdom teeth removal semi-recently, and honestly? I think the wisdom teeth hurt more.

I once had a lump on my left eyelid. It's small, but I still feel the ache imagining the scalpel digging into my eye while I was conscious.

I've had plenty of stuff done, the more recent ones include jaw surgery to correct my underbite (full anaesthesia) and maxillary sinus surgery that was performed on local anaesthesia (that failed, you can only imagine what that felt like...). And of course I've had plenty of more minor stuff, stiches, broken bones, dislocations etc.

Major surgery. Brain surgery. While I hope to never experience that again, at least I now have excuses for mistakes I make by saying I am a no-brainer, have a screw loose, etc.

I have a pro tip to get a week off work. I had my wisdom teeth removed in the military, at the very start of the week, so I could get the full week off with pay and no vacation days taken. They posed no danger whatsoever but I randomly found out about that policy and enjoy a week off on pain meds watching anime for 14 hours a day in 2010. The first day started with a Silent Möbius marathon and Heat Guy J thereafter. The procedure was even done by a military doc on base but doctors are basically free in Germany. I also got another half day off to get the stitches pulled the following week. Good times!

Look quietly into your company´s policy for wisdom teeth removal and schedule an appointment for Monday or Tuesday if things look good.

I got very very drunk at the pub. Whilst walking home, I tripped on a pothole on the sidewalk and suffered a large gash on my chin. Luckily, my Uni (which also ran a hospital as it was a med school mostly) was right there. The wound itself wasn't much of a concern besides some stitches but my colleagues who coincidentally did rounds at the ER at the time did have a laugh.

Kinda surprised that more than 70% of people here have had surgery before mmm...
I mean the age demography of this site is rather high so that is expected I guess mmm...

Maybe we should do another age demography poll again soon mmm...

there's probably a greater prevalence of manga readers amongst people who've had chronic health issues both for the lengthy convalescence times as well the obvious escapism we all enjoy in curated fiction.

most people might think a c-section is a major surgery; when it's generally done in under an hour with regional anesthesia I guess it depends who you're asking. I think people would say it was major to them.

no one is a healthcare expert; reading a lot of Black Jack you might think your absorbed twin's nervous system is viable outside of your body if only you built them an exoskeleton, then the rest of the organs and development would rapidly form. no, it's just a tumor

for someone who's had perfect health my entire life, I still remember waking up in the hospital 40yrs ago(post dental surgery) alone, with almost all the lights off and blood on my pillow not remembering what happened. It's traumatic to be apart from your parents and your siblings for the first time and be in a place of absolute silence, I had never felt so small before; I had no control over what was going on.

I'm glad modern day hospitals have greatly increased the access parents have to their children in these times, and that fewer young people have to feel the isolation experienced.
