|Drooling is the uncontrolled loss of saliva. At the same time it means a loss of face. Socially the acceptance is low. In the elderly it suggests senility. In childhood a serious handicap becomes public. Drooling can not be hided.|
Conservative treatment is disappointing. Adaptive training holds only one session. The use of anticholinergics requests increasing doses with annoying side effects. The surgical removal of the sublingual glands and retro positioning of the submandibular ducts is promising. However the margin between drooling and xerostomia is small and rigid. Moreover while the initial effect is hopefully it will but sometimes decline in time. This is due to an increased flow rate of the parotid gland.
Nevertheless there is a strong wish for treatment in individuals and their relatives. In this pages emphasis will be laid on the investigation of the salivary function before and after surgical treatment in the resting state and after citric acid stimulation. Mainly sialochemistry and sialometry techniques are used.
