Traitement du bavage : revue de la littérature

An exhaustive review of the literature shows the very relative efficiency of diverse treatments for chronic drooling. Morbidity is too high with medical treatments and behavioral treatments require active collaboration from the patient. The different surgical techniques, either based on derivation or ligature of the principal salivary ducts combined with glandular tissue extirpation, are not free of complications. There is much controversy over their efficiency due to the lack of sound evidence. Caution is therefore primordial before proposing surgery for chronic drooling: the available surgical procedures all have technical limitations and clinical trials have demonstrated many failures. At the most, the patient can expect a 50 to a maximum 80% reduction of drooling.
