This retrospective analysis evaluated acute and late toxicities of postoperative adjuvant IMRT with a simultaneous integrated boost (IMRT-SIB) in oral cavity squamous cell carcinoma (SCCHN) patients. Toxicities were mostly grade 1–2, with no grade ≥ 3 events; late xerostomia/dysphagia/hoarseness were generally mild and improved over time. The findings support parotid-sparing IMRT to reduce long-term xerostomia and help preserve quality of life.
