Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
Sialorrhoea may be due to hypersecretion of saliva,
dental malocclusion, postural problems, and an inability to recognize salivary spill. Parkinsonism or mouth ulcer or GERD may also cause. First we have to recognise the problem and treat it.
Anticholinergic medications, such as
glycopyrrolate and
scopolamine, are effective in reducing drooling, but their use may be limited by side effects. The injection of botulinum toxin type A into the parotid and submandibular glands is safe and effective in controlling drooling, but the effects fade in several months, and repeat injections are necessary. Surgical intervention, including
salivary gland excision, salivary duct ligation, and duct rerouting, provides the most effective and permanent treatment of significant sialorrhea and can greatly improve the quality of life of patients and their families or caregivers.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Penchila Prasad Kandikattu
