Treatment / Procedure

Botulinum Toxin in Sialorrhea and Excessive Salivation

In the problem of excessive saliva/drooling accompanying neurological diseases, reducing the secretion of the salivary glands may be aimed.

Short answerIn cases of excessive saliva/drooling associated with neurological diseases, reducing salivary gland secretions may be aimed for.

Purpose of the procedure

The effect is temporary and varies according to individual anatomy, clinical presentation, and the application area.

Who can be considered?

Confirmation of the diagnosis, severity of symptoms, functional goals, prior treatments, and accompanying diseases are evaluated together.

Why does sialorrhea occur?

Sialorrhea does not always mean an overproduction of saliva. Particularly in neurological diseases, the inability to manage saliva in the oral cavity and issues with swallowing function can play an important role.

The purpose of botulinum toxin

It aims to reduce drooling from the mouth and the burden of care by temporarily decreasing the activity of the salivary glands. However, completely eliminating saliva is not desired; sufficient moisture is important for oral health and swallowing.

Why is swallowing safety evaluated?

In individuals with coughing, a choking sensation, or risk of aspiration, swallowing evaluation is an important part of the treatment decision. Dry mouth and thickening secretions are also considered during follow-up.

Scientific evidence

This procedure is evaluated based on the temporary regulatory effect of botulinum toxin on neuromuscular or secretory activity. Scientific studies and relevant specialty guidelines support the importance of appropriate patient selection and individualized clinical assessment.

Safety

Pain and bruising may occur at the injection site. Temporary weakness in neighboring muscles may develop depending on the target area. If generalized weakness, swallowing difficulty, or breathing difficulty develops, urgent medical evaluation is required.

Post-procedure considerations

Follow-up is important for dry mouth, changes in saliva consistency, or changes in swallowing function. If coughing while consuming liquids or food, a choking sensation, marked swallowing difficulty, or dry mouth affecting nutrition develops, contact our clinic. Breathing difficulty requires urgent evaluation.

Our approach at our Bodrum clinic

We approach the treatment plan not merely as an injection procedure, but within the context of diagnosis, functional goals, rehabilitation, and, when necessary, coordination with relevant specialties. Treatment goals, expected benefits, potential limitations, and risks are addressed in detail during the information process.

Frequently asked questions

Is the effect permanent?

No, it decreases over time.

Is the dose the same for everyone?

No. The treatment plan is individualized according to the targeted muscle or gland, anatomy, functional findings, and clinical goals.

In whom is it evaluated?

In sialorrhea, the goal is not to completely eliminate saliva, but to reduce the impact of excessive drooling on daily life, skin care, speech, and swallowing safety. In the evaluation, swallowing function and aspiration risk are of particular importance.

What is checked during follow-up?

During follow-up, changes such as dry mouth, saliva consistency, swallowing difficulty, and coughing during feeding are assessed. If excessive dryness or worsening in swallowing function occurs, the plan is re-evaluated.

Frequently asked questions

Is the goal in sialorrhea treatment to dry the mouth completely?

No. The goal is to improve saliva control while preserving oral and swallowing functions.
