Is Jaw Surgery Risky?
This is such a broad question. . . so I'm going to separate this into lower jaw surgery (BSSO/IVRO) and upper jaw surgery (LeFort I Advancement). The broad term for these two...
What are the treatment options for salivary gland stones?
Which implant is the best for molar tooth replacement?
How soon after the bone graft can I get an implant?
What drinks to avoid after implant surgery?
Can surgery fix receding gums?
Do I need antibiotics after a bone graft?
How long after jaw surgery can you eat normally?
What helps pain after jaw surgery?
Can you put a dental bridge on an implant?
How can you remove a cyst from your gum?
What helps with pain after tooth extraction?
Hope this helps,

Can screws come loose after jaw surgery?
As a surgeon who has performed hundreds of orthognathic surgeries, I can tell you that it's unlikely for a screw to come loose, but is always a possibility. This is true moreso in the maxilla (top jaw) following a LeFort. This is because the screws used in a maxillary surgery are smaller, the bones are thinner and the bone quality is less dense. If you are truly compliant and eat a soft, non-chew diet for at least 6 weeks, then it is far less likely as well. If one of the screws does come loose, say 6 months later, a year later, 2 years later, it can usually be removed with IV sedation in the office setting, and the bones are usually healed enough by then that no additional surgery is needed. In mandibular surgery (bottom jaw), I usually will utilize bicortical screws that are quite a bit longer. Bicortical means that they engage both sides of the mandible where the bone is VERY hard. Over many years of doing
these cases, I have yet to see a mandibular screw work it's way out. I'm sure it has happened in the long history (about 70 years) of this procedure (BSSO), but it's extremely rare. Again, you must still follow the NON-CHEW diet protocol for 6 weeks following your surgery. Usually, my patients are very compliant for the first 2-3 weeks ( I do short weekly follow-ups for 6 weeks after surgery). Then they will ask the following question: "Do I REALLY need to not chew for 3-4 more weeks?" YES!!! This is the difficult timeframe because the patient is feeling much better and really feels that it will be okay to chew. This is simply not true. I had one patient that did have hardware that had loosened on the maxilla and it was about weeks 4 post-op. When I asked if he'd been chewing, he admitted that he'd had a hamburger, the weekend after the 3-week follow-up. I also saw that he had brought in a motorcycle helmet. I asked him what he rode and he told me a that it was a Harley Davidson. Since his maxilla was "loose," I said, no more chewing, SOFT BLENDED, NON-CHEW diet ONLY and NO HARLEY for the next 6 weeks! Wouldn't you know it, he came back 2 weeks later and the jaw had tightened up. This was a close call as we almost had to return to the OR to re-fixate him (new plates and screws). Fortunately, that wasn't required. I now tell all of my patients that in addition to 6 weeks of soft, non-chew diet, no motorcycle riding or anything similar that might cause jarring/vibration of the maxilla. See there, even crusty old surgeons can learn a few things.
I hope this answer helps you out. Good luck with your surgery and remember to keep hydrated afterwards and use a soft, blenderized diet. There are lots of good things that you can blend and still taste suprisingly well.

Can you sleep on your side after jaw surgery?
I assume that you are referring to Orthognathic Jaw Surgery. In that case, I recommend that my patients sleep at a 30-45 degree angle using a pillow made for reading or (if that's not available) using three pillows to prop you up at night, for the first week following surgery. If you have a bed that adjusts, that works great, too. As a 27-year-old, you will heal enough by then that you can (probably) go back to your regular sleep pattern after that. We are trying to avoid pooling of blood on either or both sides (so NO side sleeping the first week).
