Botox, or botulinum toxin, has been used in various medical conditions due to its ability to cause temporary muscle weakness. It is often used in cosmetic procedures to reduce wrinkles, but it has also been used to treat conditions like hyperhidrosis (excessive sweating) and bruxism (teeth grinding). Some studies have suggested that Botox might be effective in reducing the size of salivary glands, including the submandibular glands.

However, this is not a commonly performed procedure, and the evidence is not as strong as for other uses of Botox. It would be essential to have a thorough discussion with your doctor about the potential benefits and risks.

Regarding the need for repeated injections, Botox's effects are temporary, so if it did reduce the size of your glands, you would likely need repeat injections to maintain the effect. The frequency of these injections would depend on how quickly your body metabolizes the Botox, but generally, they might be needed every 3-6 months.

As for the use of ultrasound guidance, it can help ensure the Botox is injected directly into the gland, reducing the risk of complications. However, some experienced practitioners might feel comfortable performing the injection without ultrasound guidance. This is something you would want to discuss further with your doctor to understand their reasoning and comfort level with the procedure.
