A choker works, or a scarf. Chokers are cute and always in style.
If you're swimming in cash, surgery is an option. But if it's not too noticeable you have to weigh the possible benefit against the cost and risks. It's a couple thousand dollars and leaves a telltale scar. Also, you could lose a lot of vocal range if the surgeon shaves away too much tissue.
So if it's only visible from certain angles, or only if you tilt your head back, it might not be worth the risk or cost for the surgery.
If you are considering surgery, definitely get outside opinions -- at least ask your friends, if not consult with an actual surgeon. I assumed for years that I would need a tracheal shave because I can feel a lump when I put my hand to my throat. But when I actually started asking my partner & friends about it, they said "you have an adams apple?" This threw me for a loop, and I thought they were lying to make me feel better. But when I took some pictures of the area, I realized they were totally right -- despite the way it feels, my trachea bump doesn't show from most angles. And when it does show, it's small enough to be within female norms.
So in the end I decided against a tracheal shave, and in the long run that will save me money and brain cells (i.e. avoiding anesthesia). While a surgeon might have warned me against the procedure if I'd suggested it, you never know. It pays to get those outside opinions.
