Probably not, but it’s certainly worth trying.
The throat is pretty well protected. The skin is thick and tough, the trachea itself is made of hard cartilage rings, and it’s actually surprisingly difficult for a human to get a good mouth-hold on another human’s neck. (If you have a significant other who is okay with this, give it a try; don’t actually bite down though).
Hunters who do the throat-ripping thing usually have longer mouths than we do, which helps them get a grip on their prey. Humans have fairly short mouths by comparison, and really aren’t evolutionarily adapted for this task.
Now, that is not to say that having a human try to rip out your throat is not an absolutely fucking terrifying thing, because it is, and flesh missing from the neck can be psychologically devastating even if it’s not actually physically lethal. Your character could probably significantly damage the musculature and the skin, and possibly cause a severe venous bleed from the external or internal jugular.
If your character is going to get any better of a bite than that they’ll need their hands to hold the neck in place while they bite.
(Also, bites in fights is proooobably more @howtofightwrite‘s territory much more than it is mine 😉 ).
Best of luck!

We’ve answered this kind of question before on several occasions, they’re in the biting and the only unfair fight tags. For a better exploration of this topic, read this ask answered by Starke about biting off fingers.
The short answer is that physically you certainly could take a good sized chunk out of their neck with your teeth (terrifying enough in and of itself), the problem is the psychology necessary to follow through with it. Biting is straight up nasty and, when it comes to other humans, runs up hard against a whole bunch of self-preservation instincts that any protagonist would need to fight past in order to pull it off.
More than that, with his hands bound he’d have no way to hold onto his opponent thus not enough time to get a good bite off. He’s got to get to them, lunge in fast enough to get his teeth around their throat or (possibly) lure them close enough to get the bite off, and hope they don’t stop his head with their hands (or head) before he gets there. Attacking the throat, even with the element of surprise, is a great way to get someone to guard it.
The truth is in the heat of battle you’re more likely to come up with
ramming your head into your attackers throat (more effective) to a
temporary stun, then follow up with a headbutt to their face or move on
to using your shoulders and legs before thinking of your teeth. (It’s
difficult, but you can kick with your hands tied behind your back.)
Strikes to the throat can crush or halt your ability to breathe entirely
with enough force, but are more often used as stunners, to distract via
fear (brain freak out, vital place has been attacked, internal screaming) and temporary loss of breath. These create what we call “openings” as in openings in defense.
As @scriptmedic says, the throat is
fairly well defended by your physiology. This is going to be true of
the most obviously vital places.
You get far more mileage out of convincing someone they’re being attacked there in order to strike elsewhere because your instincts will move to defend those places at all cost. Like your hands automatically rising to your throat if it feels like someone is going to hit it. (This doesn’t make you good at blocking, it’s just instinctual order of operation. Sacrifice the less necessary body part for the essential one. This is why we never fight on instinct.)
And frankly, depending on his position, a fake out headbutt to the
throat while actually hitting the stomach (rising on that upward
diagonal into the diaphragm) will probably be more effective. Then, if
they’re still standing, headbutt to the face.
The first question is: can he bite?
No, really think about it. He cannot hesitate, not at all. A split second hesitation and he’s done for, he must complete the act in one simultaneous move. He can’t drop the moment he tastes the dirt and sweat coming with their flesh, then the blood running over his tongue, and get enough for a lethal rip away while his opponent is trying to get away. (And the attacker is, he started backing up the second the protagonist came at him, and the protagonist has no way to make him stand still.)
Remember, we humans don’t have the sharp teeth of a carnivore to sink in and keep our prey from running.
I mean it, spend some time thinking about what it’d feel like, taste like, and smell like. Then think about it from his perspective, it’s a dramatic idea but can he follow through?
The second question is: can he move in and bite in .5 seconds?
This is the sort of attack where he doesn’t get a second shot, and the kind where threat level is upgraded into automatic kill territory. Biting is socially unacceptable, dishonorable, and offensive.
The four scenarios for the victim are terrified enough to be paralyzed into inaction, terrified into action, so terrified they run, and righteously pissed. The protagonist has got to kill before fight, flight, or freeze takes effect. (And they can’t, really, unless they somehow manage to take out the carotid.)
The third question is: will the attacker be shocked enough by this bite to not retaliate while it’s happening?
The problem with the mechanics of a bite is you’ve got to get your teeth on the other guy’s throat for a solid rip away (and not miss because they moved their head or the teeth slip off), this takes time. The worst thing if he gets seized by the hair, punched in the face, stabbed by a knife, or gut checked by a sword pommel in the middle of (or slightly before) this bite going down. The protagonist needs to be mostly through the process of tearing by the time this antagonist realizes what’s happening. Even then, he’s in just the right range for some vicious retaliation. Even if he gets enough of a bite to kill, the other guy isn’t going to die right away. That could easily lead to an “I’m Taking You With Me” scenario.
The good news is that if he does manage a bite, he doesn’t need to take their windpipe. The human mouth is a vile, dirty, disgusting place and his victim will most likely die from either blood loss (depending on where he bites) or an infection.
The downside is his mouth will be full of their blood, and he’ll probably get sick too. If he doesn’t manage to escape, whoever else is working with his attacker will probably kill him because biting another human is as feral as it gets and automatically shifts whoever does it from “human being” into “animal”. While dehumanizing yourself to terrify your victims is a great strategy for psychological warfare, it doesn’t work so well when the shoe is on the other foot. In writing, you also run the risk of dehumanizing the character for the audience too. If it fails or the other guy lives, then he’s still the crazy idiot who tried to grab a guy’s throat with his teeth.
The trick to writing good fight scenes is being able to see and plan from the perspective of both parties in a fight. When trying to figure out whether something is possible never assume the guy they’re doing this action to is just going to stand there and take it. Everyone wants to live.
When talking about fighting, you’ve got to go through two steps. The first is the purely theoretical of “would it work?”, if the answer is maybe then ask “what would the other guy do in response?”
Most of the stupidest fighting ideas in real life die in this second stage (sometimes on the battlefield itself) because a live actor is much more difficult to deal with than lifeless dummy or someone whose given you permission to put your teeth around their throat. If the idea doesn’t float or sound good when pit against resistance then it’s usually no good, even if you’re crazy enough or desperate enough to try.
If rapid escalation into sudden, terrifying brutality isn’t in this character’s skill set (eye crushing, biting, and others) then this approach probably won’t work out for him. Does he think about ripping people’s throats with his teeth on a general basis? Has he ripped throats out before? Does he find the idea repulsive? If there’s a no to any of these questions or a yes to the last one then this approach may not be right for him.
1) With only his head, shoulders, and feet, your protagonist could put his attacker on the ground and then crush his throat with their foot. It would take slightly longer, be less shocking, and require a finer grasp of tactics, but that’s possible.
This has the potential to be exciting. I understand, however, that it is very difficult for someone without a martial arts background to think with their feet or plan a fight scene around kicks or anything other than fists.
2) Ram their attacker and drive them both to the ground, and give their head a few solid hits with their forehead if they manage to land on top. Then run for it.
This one would be much easier to go with, though their chances of killing via this method are slim unless they manage to land a concussion or damage the brain some other way. However, it could provide them with a chance to make an exit if they can do enough damage so their attacker doesn’t try to stop them from escaping.
There’s also the risk of what the other guy does with his hands. However, the one who lands on top is usually in the best position.
3) The environment surrounding your character and where they are fighting can become a weapon they utilize in their escape.
This is often overlooked in fight scenes, but utilizing the environment and terrain is a huge factor in combat. There may be a way for your protagonist to kill their attacker sitting right next to them, or they can take advantage of.
Throwing your body weight around is something anyone can do because your utilizing your core and momentum to destabilize the enemy’s balance. This can be done with just your shoulder and feet planted in the right place. Knock ‘em into walls. Use this force to create new, creative means of attack and opportunities in the environment.
4) Stun this guy, duck past, and run for a crowded area to make his escape.
This is what it says on the tin.
5) Or wait and plan an escape later when he’s in a better position.
This may not work depending on what’s about to happen to him in prison. The best time for a prison break is not from the prison itself but while the prisoner is in transit. Try to remember, depending on the situation, your character needs to escape in a way that keeps his pursuers from following him. This doesn’t necessarily they have to die. (At least, in this exact moment.)
6) He tries it and fails.
He tries it, he fails, or might be mildly successful but not successful enough, gets caught and the situation plays out another way.
Sometimes, scenes don’t go the way we want but that doesn’t mean the
story ends. Another interesting path is waiting right around the corner.
7) You ignore all advice and just do it. YOLO.
Try it and see what happens.
