SALIVARY GLANDS (Sialography) RADIOGRAPHIC PROCEDURE Prof. Akram Asbeutah, PhD Department of Radiologic Sciences Faculty of Allied Health Sciences Kuwait University Objectives • Radiographic anatomy of Salivary glands • Radiographic procedures of Salivary Glands • Radiographic positioning of Salivary Glands A- Radiographic AnatomySalivary Glands Anatomy of Salivary Glands Happens 70% -80% benign tumour • Parotid below your ear and over the masseter Mostly danger happens malignant tumour • Submandibular is under lower edge of mandible • Sublingual is deep to the tongue in floor of mouth • All have ducts that empty into the oral cavity Anatomy of Parotid Salivary Glands • They are located anterior and inferior to ear • The largest of salivary glands • Superficial & deep parts • It duct is known as Stensen’s duct and it is 5-7 cm in length • Its duct open opposite second upper molar tooth Mumps - ‫خاز باز‬ • • • • • Happen bc of : * acute inflammation Rejection Allergy Pregnant The duct may be: • stone • Stricture • Inflammation • Tumour • Injury Anatomy of Submandibular Salivary Glands • It is the second largest salivary gland • It is located inferior and medial to mandible • It has superficial and deep parts • Its duct called Wharton’s duct and measures 5 cm in length and opens at the sides of the base of the frenulum of the tongue Collimation 70-80 kvp Control PA , LAT, LAT/OBLIQ, flush image ( uses lemon to take contrast out ) Improves the contrast resolution Anatomy of Sublingual Salivary Glands • They are the smallest of the salivary glands • They are numerous and located beneath the mucous membrane of the floor of the mouth • About 12 small ducts called ducts of Rivinus • One of the duct might enlarge and called Bartholin’s duct and join the submandibular duct Sialoectasis Functions of Salivary Glands • Helps keep teeth and mouth clean • Facilitates mastication and deglutition • Wet food for easier swallowing • Dissolves food for tasting • Bicarbonate ions buffer acidic foods – bulemia---vomiting hurts the enamel on your teeth • Chemical digestion of starch begins with enzyme (salivary amylase) • Enzyme (lysozyme) ---helps destroy bacteria • Protects mouth from infection with its rinsing action---1 to 1 and 1/2qts/day B- Radiographic Procedures of Salivary Glands (Sialogram) Sialography Procedure Silography Indications & Contraindications Patient Preparation for Sialography Procedure • The patients should remove any dentures or other associated orthodontics • All radiopaque items should be removed from the head & neck region • The procedure and possible complications should be explained to the patient • Consent form should be obtained prior to the procedure Major & Accessory Equipment for Sialography Procedure C- Radiographic Positioning of Salivary Glands Radiographic Positioning of Salivary Glands Radiographic Anatomy of Parotid Salivary Glands Radiographic Positioning of Salivary Glands Submandibular Radiographic Anatomy of Submanidbular Salivary Glands
