Salivary gland ductal obstruction is a frequently presenting disorder of the salivary glands. Diagnosis of this condition includes ultrasound, sialography, or MR sialogram. However, each technique has its own limitations. Endoscopy of salivary glands allows optical exploration of the salivary gland system and incorporates both diagnostic and therapeutic procedures for intraductal pathologies like sialilithiasis. Sialendoscopy is one of the most fascinating innovations in the field of Head and Neck Surgery and was introduced in the early 1990s. As a minimally invasive technique, sialendoscopy has shifted from conventional open surgical resection procedures to endoscopic and gland preservation techniques. This article enlightens this novel technique, which will soon be included in the repertoire of all clinicians in the future.
