IMPACT OF INTENSITY MODULATED RADIATION THERAPY ON THE SALIVARY GLANDS FUNCTION AND SALIVA FLOW RATE

In patients with head and neck cancer, the most common issue after radiation treatment is xerostomia consequences of that, which are affecting quality everyday life patient. Subjectively manifested as dryness in oral cavity, followed obstructed chewing swallowing food. Mostly it happens because death cells gland that supposed to be dividing, caused by radiation. To improve patients’ treatment, IMRT approach has been considered a better solution for tissue sparing during therefore, decrease severity intensity following  xerostomia. The technique allows chosen dose applied specifically on where be, surrounding healthy parts from unnecessary aim this study was evaluate influence Intensity Modulated Radiation therapy (IMRT), different dosage, function salivary glands. For were analyzed total number 87 surveys, 41 them used detail analysis. This based narrative review published articles written English language, reporting results related use modulated cancer. gathered have shown glands can many cases protected or even restored some level, therefore resulting reduced its’ negative effects could minimized using improved IMRT. studies evaluated levels found significantly lower groups treated technique, compared other group conventional therapy. Also, big dosage beams, what depends outcome salivation Key words: therapy, xerostomia, hypo-function, saliva reduction, flow rate, sparing.
