Diagnostic and therapy of salivary gland diseases

Significant progress in the diagnosis and therapy of salivary gland diseases has been made in recent years. The new technique of diagnostic and interventional sialendoscopy has made an important contribution and is indicated in every case of obstructive sialadenitis. The number of open resections of salivary glands due to stones will clearly decrease in the future in favor of endoscopic removal. Due to recent publications on the appropriate extent of salivary gland resection in benign tumors, more and more specimens with reduced cuffs of healthy salivary gland tissue will be sent to the pathologists. Ultrasound will stay the procedure of first choice for imaging of salivary gland diseases in Germany. In combination with fine-needle aspiration cytology high sensitivity and specificity for the assessment of salivary gland tumors can be achieved. Diffusion-weighted magnetic resonance imaging (MRI) is a new imaging tool and the power of distinction of pleomorphic adenoma from malignant tumors is promising. The use of botulinum toxin for salivary glands diseases is increasing. Intraglandular injections have been shown to induce salivary gland atrophy in animal experiments. The availability of biologicals is currently yielding new aspects for the treatment of Sjogren's disease.
