Feeding tubes were required in 26% of the patients. Grade ≥2 late xerostomia and dysphagia were 11% and 8%, respectively. Chemotherapy, tumor subsite, and bilateral neck irradiation correlate significantly with toxicity. Quality of life (QOL) scores deteriorate during and shortly after treatment but returned in all scales to baseline scores within 6 to 12 months, with the exception of xerostomia.</p> </sec> <sec id="hed23244-sec-0004" sec-type="section"> <title>Conclusion</title> <p>Brachytherapy boost and neck dissection (in node‐positive oropharyngeal cancer) after 46‐Gy of IMRT resulted in excellent outcomes with low incidence of late toxicity and good QOL scores. © 2013 Wiley Periodicals, Inc. <italic>Head Neck</italic> 35: 1689–1697, 2012</p> </sec> </abstract>
