[Lithiasic salivary gland pathologies].

LITHIASIC SALIVARY GLAND PATHOLOGIES. Sialolithiasis is the most frequent pathology affecting the salivary glands. Almost 80% of these lithiasis affect the submandibular gland, in the Wharton duct whilst 20% occur in the parotid gland in the Stenon duct. The diagnosis is based on typical patient interrogation and clinical symptoms (intermittent facial swelling associated with eating, sialadenitis) and/or on paraclinical examination. Ultrasound echography is often prescribed, but CT-scan and sialo-MRI offer a more precise preoperative assessment. Minimally-invasive gland-preserving techniques such as sialendoscopy (combined or not with transoral duct surgery) are nowadays considered to be the method of first choice. These methods reach success rates above 80% and significantly reduce surgical complications and hospital stay.
